Many craftsmen know that you can make a compressor from the refrigerator with your own hands! Can . But, few people know how to do it! In this article, we will try to present an exhaustive answer, how to make a compressor with your own hands so that everyone can create this equipment at home.

After all, if you figure it out, in fact the air compressor is needed in every garage. With the help of the compressor, you can, pump the wheels without visiting a hundred or tireage, supply air to a working pneumatic tool or simply blew dust from the surface treated. So, consider the installation option for painting.

Factory or homemade compressor

Regarding the painting station there is a list of certain requirements. The main condition is the need for uniform air intake, without any impurities. The standard defects that are due to the presence of foreign particles can be attributed to the graininess, shagreen or cavity on the enamel coating. In the case of uneven flow of paint, drums or matte heel may form.

Of course, if you pay attention to branded air compressors, such installations are equipped with all the necessary functions for high-quality airbrush. The only disadvantage of such aggregates is their cost.

In order to save money and at the same time create a functional model that will not give up professional equipment, you need to familiarize yourself with the theoretical information base or view the video on the topic "Compressor for painting a car with your own hands."


The principle of operation of any model, regardless of whether it is self-made or the factory, one and the same. The tank creates excessive pressure. Different air injection method (manual, mechanical). In the case of manual feed, there is a significant saving of money, but a lot of energy is consumed. After all, the process requires constant control.

Automatic inflation makes it possible to avoid these disadvantages, except that the oil for the air compressor requires its periodic replacement. Thus, there is a uniform air supply to the distribution device. In the theory, it looks extremely simple, so you create a working compressor station, possibly in a short time.

We do with your own hands

So, we choose the manufacture of the installation for painting from the ordinary car chamber. The list is needed:

  1. Car chamber executing a receiver;
  2. Pump with a pressure gauge, performing a supercharger;
  3. Chamber nipple;
  4. Remkomplekt;
  5. Normal awl.

Now you can start making the compressor station. The camera must be checked for tightness, for this it needs to be met. If there are air leaks, it is necessary to solve this problem, or by sticking, or with the help of volcanization of raw rubber.

After that, in the manufactured receiver with a selection, you need to do a hole. A nipple will be placed here through which a uniform jet of compressed air will go.

Additional fitting is attached by attaching. Remkomplekt will help in solving this task. Then the fitting is connected to the paintopult. To check how the air flow comes to you to unscrew the nipple.

At the same time, native nipple remains, it will serve as a valve, and retain excessive pressure. In the end, it is necessary to determine the level of pressure by spraying the paint on the metal surface. If the enamel falls evenly, it means that the installation works well.

In addition, the pressure value can be checked using a pressure gauge. But, its level, even after pressing the aerator key, should not be scorching.

Describing the compressor is easy, but after its manufacture, anyone can make sure that the repair or painting of the car will become much more effective than it was with a canister.

The latter's incidence should be attributed to the fact that it is necessary to avoid water or dust into the car chamber in every way. So that these particles are not subsequently entering the paintopult, otherwise it is necessary to paint again.

As a result of the proper operation, the established installation will work for a long time, but it is better to automate the pumping of the air.

Semi-professional air supercharger

Specialists have repeatedly made feedback on the fact that homemade compressor installations have a longer service life. What the comparison was made with domestic and foreign models.

It is natural, because the installation is made by your own hands. Therefore, we consider the option how to make a compressor from a refrigerator, which will not give up even the products of famous firms. So, for its manufacture, the following list of materials is necessary:

  • Receiver for compressor;
  • Pressure gauge;
  • Relay to control the pressure in the compressor;
  • Threaded adapters;
  • Fuel filter (gasoline);
  • Reducer with an oil-separating filter;
  • Cross plumbing with threads ¾ inches;
  • Motor for compressor installation;
  • Car clamps;
  • Motor oil (10W40);
  • Switch (220 V);
  • Oil resistant hose;
  • Brass tubes;
  • Ordinary syringe;
  • Thick board;
  • Comceptor rust converter;
  • Filter of the power system (diesel);
  • Metal paint;
  • Nuts, washers, hairpins;
  • Wheels for furniture;
  • Sealant, tape FMU;
  • Filter.

Working mechanism

To simplify the procedure, the engine can serve as a compressor from the old refrigeration unit of the Soviet sample. There is one positive moment here, namely, the presence of a starting relay of the compressor.


Soviet models exceed their foreign competitors, producing higher pressure. It is necessary after extracting the executive unit to put it in order, freed from the stood rust.

Rust converter will help to produce compressor processing to avoid further oxidation. Thus, the work motor body will be prepared for the subsequent painting.

Installation scheme

After performing the introductory part, you can start replacing the oil. After all, if you do not crush the soul, then little, which refrigerator managed to be subject to regularly or replacing the oil. However, such a course of events is also quite acquitted, because in this case the system is in full insulation from atmospheric effects.

So, the semi-synthetic oil is quite suitable for this procedure. Especially since it is no worse than compressor oil, and has a sufficient amount of useful additives.

We go further, and finds 3 tubes on the compressor, 2 of which are open, one is posant. In our case, open tubes will be used to circulate air (input and output). To understand how the air moves, you need to apply for a compressor for a short time. After that, remember or record, which air duct draws air, and what, on the contrary, releases.

The appointment of the sealed tube is a regulatory oil change. Therefore, the closed end should be deleted. This will help us with a supreme who need to produce inscribed in a circle of the tube. It should be viewed that the chips do not get inside the compressor.

After it is necessary to break the end of the tube and drain the oil into any capacity in order to establish its volume for subsequent replacement. Then we take the syringe, and pour semi-synthetic, but, in a larger volume than it was fused.

When the oil is flooded, you need to drown out the engine lubrication system. This can be done by selecting the screw, after which this screw is winding the FUM ribbon and tightened into the tube. It's time to remind you that from the output air tube of the supercharger will sometimes be seeded oil drops.

Therefore, an oil separator for the compressor will come to the rescue.

When the designated works are completed, time to start assembling the installation. You need to start with the strengthening of the engine with a launch relay on a wooden base, so that it is in this position as it was on the frame.

This is necessary due to the sensitivity of the compressor relay to the spatial position. To determine more precisely, an arrow must be drawn on the top cover. It is important to observe accuracy here, because, the correct switching of the modes will depend on the installation of the compressor.

Air container

An excellent solution to the problem will be cylinders from fire extinguishers. It depends on their ability to withstand high pressure, in addition, the cylinders have a significant margin of strength, are perfectly suitable as attached equipment.

So, take as the basis of the OU-10 fire extinguisher. Its working volume is 10 liters. According to the technical characteristics, the cylinder withstands the pressure - 15 MPa. Now you need to unscrew the locking device from our billet, then screw the adapter.

In this case, in the case of detection of traces of corrosion, it is necessary to remove them with a rust converter. Of course, the external deletion is simple, but internally will require patience. Therefore, we fill the converter inside the cylinder, and we take the contents.

After cleaning, you can screw the plumbing cross. Thus, two work details of our compressor installation were prepared.

Installation of parts

To make it easier to store and move work items, they are best located on the same database. As it has already been previously said, we need a wooden board that will serve as a basis for reliable fastening of the engine, as well as the fire extinguisher housing.


Therefore, as the engine mount, we will use threaded studs that need to be used in pre-drilled holes. Of course, plus the nuts (washers) will also be needed.

Then you need to position the receiver in a vertical position, here there will be 3 sheets of plywood. At the same time in one sheet you need to do a hole for a balloon. The remaining sheets are mounted with self-draws to the main board and glue with the sheet that holds the receiver.

But, on the eve you still need to wipe the recess under the bottom of the receiver in the wooden base. And finally, that the design is maneuverable, you need to fasten the furniture wheels to its base.

After all made, you need to protect the system from possible dust. A gasoline filter of coarse fuel purification will come to the rescue. It will perform the function of the air intake.

The rubber hose and the supercharger inlet tube will be involved. It should be noted that at the entrance of the compressor station is low pressure, and, it means, the gain of contact with the help of automotive clamps is not necessary.

Thus, we have created an input filter for compressor installation. At the outlet of the station you need to install an oil separator, which will block the ingress of water particles. The power system filter will be used here. Due to the fact that the pressure at the output of the compressor station is increased, automobile clamps will be used from this place.

Thus, the queue reached the oil separatory filter. In this case, it needs to be connected to the input of the gearbox, which is needed for the disconnection of the tank and the output of the pressure supercharger. So, we screw out the exit to the previously prepared crossbar on the left side, and on the right we screw the pressure gauge, thanks to which you can control the balloon pressure. On top of the crossbar need to screw the adjusting relay.

The presence of an adjustment relay will give the ability to set the recruit pressure height range, as well as to interrupt the power circuit in the supercharger. When it comes to the actuator, it is recommended to use RM5 (RDM5).

With these devices, the compressor will be turned on, in the event of a drop in the air pressure in the tank below the set mark and turn off when the specified parameters are exceeded.

The desired pressure is adjusted on the relay using two springs. The function of the large spring is to create minimal pressure, while the small spring is responsible for adjusting the upper limit, actually installing the border of disabling the compressor installation.

RM5 (RDM5) was primary to use in the water supply network, in fact, these are conventional two-contact switches. In our case, one contact is used to connect zero network 220 V, while the second contact is connected to the supercharger.

We carry out the network phase through the toggle switch to connect to the second input of the compressor station. In the presence of a toggler in the electrical circuit, we will be able to make a quick disconnection of the system from the network, which will get rid of the runner towards the socket.

Naturally, all compounds must be released and carefully exhibited. After that, you can paint the finished installation and conduct test tests.

Adjust the pressure

So, after assembling the design, it is quite natural to conduct it. To do this, connect the paintopult, or as an option is a pneumatic equipment. Then, not including the toggle switch, make a plug into the network.


Adjusting relays are installed at minimum pressure, and make the power supply to the supercharger. Do not forget for a pressure gauge that allows you to control the pressure in the tank. After we managed to make sure that the relay turns off the engine, you need to check the tightness of the connections.

A classic soap solution can help here. If the system has been tested for tightness, you can make air remnants from the tank chamber. It is necessary to pay attention to that in the event of a pressure drop below the limits, the relay must start the compressor. In the event of the health of all systems, it is possible to embark on the color of any part.

It should not be loaded by pre-treatment of metal. It is important for us to establish the pressure necessary for painting.

Such experimentation will give us the opportunity to determine the atmospheric size so that the painting of any product happened to the uniform layer. In addition, it is very important that all this process takes place with a minimal number of supercharger.

Thus, you can bother the results. Production of a car compressor, lifting lesson for every motorist.

Of course, it is difficult to argue with the fact that the second version is more difficult and will take longer to manufacture, but, thanks to the system of automatic pressure control, as well as the presence of a supercharger starting work with such equipment, will become one solid pleasure.

In addition, you will not need to control the receiver camera more. Such a station will allow you to paint the car, fence in the village or garage doors.

For the continuous operation of the created compressor, it will be necessary to carry out periodic regulations. . To make a plum of oil, you can use the syringe. In this case, we unscrew the plug hole, we wear a hose on the tube and pumping outlaughter. Also, fresh oil can be downloaded using a syringe. Filters change as needed, including in the case of a decrease in the speed of filling the tank chamber.

Make or buy

Today, the market is filled with a variety of compressor equipment. There are piston installations, vibration units, screw stations and other devices that are manufactured for different purposes. Finished installations can be purchased in auto parts stores or profile sites.

A large range may make it difficult to choose the desired product. But be that as it may, if you decide to buy a finished station, make an emphasis on the study of technical parameters, cost and reviews.

To obtain quality assurance, it is better to purchase equipment of well-known brands, however, an expensive product justifies itself in the event of a professional car repair. Little-known products can bring you, so it is better not to risk.


Often, budget options have low-quality materials. There are often cases of setting facilities, due to instant breakdowns of individual parts, while the warranty repair takes a lot of time.

As already mentioned, his own assembly is often more reliable than factory. An individual plus is the technical parameters. For example, according to statistics, refrigerator compressors serve dozens of years. Regarding the fire extinguisher, it can be said that this product has a tenfold safety margin.

Therefore, it is better not to buy what you are unsure. In addition, after studying the current material, you know what to make a compressor with your own hands, you can even in domestic conditions. The well-made device will become the envy of the neighbors of the garage.

Another story

Let's start with the design of the technical requirements for the fetus of its own engineering. Suppose that it all started with the purchase of a new double-acting airbrush. Therefore, the issue of manufacturing compressor installation with the receiver became extremely necessary.

Double action airbrush has the ability to control the air flow, as well as lock it and open the air duct. In Europe, such a device is used with a separate cylinder for compressed air. So, the compressor with the reservoir serves as a capacity for collecting air, and the airbrush uses this air.

Of course, the main component is the compressor. An old refrigerator will come to the rescue, from which you can remove an excellent compressor. To do this, you can walk on sites that sell refrigeration equipment.

We define at a price, and order delivery, but before you still need to write the name of the manufacturer and visit the site. So, in our case, the manufacturer is Danfoss. On the company's website, we download the technical description of the compressor.

Next, consider this option as the receiver for the compressor with your own hands. Here, of course, a reservoir is needed, which has been manufactured for gas content or can withstand high pressure. Optimally, if such a container meets the requirements of GOST. Therefore, immediately exclude the container, by type of plastic canister or bottles. Consider options for tanks:

  1. Carbon dioxide fire extinguisher. Withstand pressure - 10 atmospheres. Capacity - 3 l / 5 l / 10 l. Cons - at the entrance metric thread.
  2. Hydroaccumulator. Good capacity, with a small operating pressure. At the entrance convenient carving. Cons - needs to bend, since, from the inside it is divided into a membrane that contains carbon dioxide. The membrane needs to be deleted.
  3. Oxygen balloon. Withstands high pressure. Cons - only extremely heavy models are available.
  4. Propane cylinder. Overall, analogous to the fire extinguisher, but the manufacturer does not recommend their use for compressed air.

Binding links

After we have decided on the compressor, and chose a suitable product for the receiver, the next step will be their association. In addition, it is necessary to solve the problem to enter the airbrush.

You can start with the node that is attached directly to the receiver, and will provide air distribution. It is necessary to recall that the key factor is its compatibility with the receiver connector. Next, we draw attention to the pressure relay, which will be shutdown and turning on the compressor.

The optimal option for the relay will be RDM-5, which is used for water supply systems. This model is widely available on sale, and is good because its connecting element is designed for an external inch thread.


Then we are determined with the pressure indication in the receiver. To do this, we need a pressure gauge for 10 atmospheres, it also has a suitable connecting size. And we still need a static device.

Then we are engaged in the air preparation unit. In the hose, which leads to the airbrush, you need to submit pressure. Accordingly, there is a need for a gearbox, with the limit of pressure regulation up to 10 atmospheres, and it is desirable that a pressure gauge and filter oil separator attached to it.

Using a pressure gauge, we will control the pressure, and the filter will ensure the incomprehension of particles of the compressor oil from the receiver. But, it is not necessary to be confused with a lubricator filter, which performs the diametrically opposite function.

We will continue to collect materials, and it's time to prepare fittings, turns, tees. As a basic size, we take inch. To determine the amount, the diagram of the distribution and air preparation unit is needed.

We will also need external and internal adapters. If you wish, you can make a plan to make a compressor. The next stage is the placement of the finished design. As an option, chipboard plates can be approached.

Of course, in order not to swear with a mat during the movement of the station on the workshop, it is desirable to immediately resolve the issue with legs-rollers. Any furniture store with joy to sell them. To save space, you can make a two-story design. True, you may need long bolts. So, we summarize the planning stage, the list of components:

  • Compressor;
  • Receiver;
  • Pressure switch;
  • Pressure gauge;
  • Filter gearbox;
  • Emergency valve;
  • Fittings, adapters;
  • Plumbing pads, fum-tape, sealant;
  • Cables, switch, plug;
  • Flexible oil-resistant hose;
  • Sheet of chipboard
  • Legs, bolts, nuts, washers and tools.

We start assembly

The ideal will be the dismantling of the node of the fire extinguisher and the welding of the adapter fitting. An alternative way is to unscrew the part of the valve, leaving the inner mechanics and removing the control element, then screw the adapter to one output with an internal inch thread, to another adapter from 1 to 38.

Using the adjustable key, twist adapters according to the scheme. Next, mounted gearbox, pressure gauge, pressure switch and adapter on a flexible hose.

The next step is the screw to the wheels to the chipboard sheet. Since the design will be two-level, you need to drill holes for the studs. After that, we climb into your place a fire extinguisher.

In the case of using a hydroaccumulator, the assembly scheme is even easier, since it has brackets from above and below. Therefore, the lower mounts are screwed to the base, and the tops serve to install the compressor.

In our case, the second floor must be constructed. For this, the layout is made, the holes are drilled, and the top and bottom floors are fastened. After that, the compressor is mounted on the second floor. Silicone gaskets are suitable for decreasing vibration.

When installing the compressor, we put the washers. We screw the air distribution module to the tank. Using the hose and clamps, tightly connect the compressor output and the input of the air preparation unit.

Now it's time to work with the connection scheme. It will be a relevant jumper installation. The protective elements will not prevent. The connection line should pass through the relay and switch. The connection itself will be as follows.

From the plug, the phase wire goes to the switch. Then connects to the desired relay terminal. In the absence of a ground wire, we start the zero wire on the terminal grounding the relay.

Already from the relay, the phase wire and zero wire goes to a starting device for driveing \u200b\u200bthe compressor station and are connected according to the scheme to the desired terminals. Further, on the terminal block of the starter, we set the jumper by spike.

It will ensure the connection of the windings to the phase. Cable can be laid in plastic ties. Check and start the installation. Then paint it.

For painting cars, as a rule, a device for spraying paint is used. This is an air compressor and a kraskopult connected to it. If you are planning such equipment for your garage, you can make a compressor with your own hands or purchase the factory model.

It is quite obvious that buying the finished product is much easier. This entails less labor. However, independent production is a significant economy of finance. In addition, experts argue that the homemade powerful electric compressor for cars with a relay and the receiver can be much more efficient and durable of the serial product. Below we will tell about how to make a compressor for painting a car for a voltage in 220V alone.


Compressor for painting cars with your own hands

Obviously, we need to collect certain materials to work. So, to assemble a homemade air compressor for a voltage of 220V for painting cars, we will need the following details:

  • pressure gauge;
  • reducer with oil protection filter and moisture;
  • relay for pressure adjustment;
  • purification filter for gasoline engines;
  • cross for water with carvings inside;
  • threaded adapters;
  • clamps;
  • motor;
  • receiver;
  • engine oil;
  • 220V voltage switch;

Materials for homemade compressor
  • tubes from brass;
  • oil resistant hose;
  • wooden plank;
  • syringe;
  • rust removal tool;
  • studs, nuts, washers;
  • sealant, fuma ribbon;
  • emale for metal;
  • pillet or file
  • wheels from furniture;
  • motor diesel filter.

Collect this list is easy. After everything you need assembled, we can proceed to work.

Collect the engine

We start working from the most important element - the engine that will create the desired amount of air pressure. Here we can use the motor from an unnecessary refrigerator.

Its device includes a relay that will be needed in order to maintain a given air pressure value. Experts argue that the old Soviet models make it possible to achieve higher pressure than new imports of imported production.

Remove the engine from the refrigerator, carefully clean it and processes the means to avoid the oxidation of the housing. After that, it will be ready for painting.


Remove the engine refrigerator

Now it is necessary to replace the oil in the motor. For this, the semi-synthetic is quite suitable - it is not worse than the engine and has a lot of useful additives.

There are 3 tubes in the motor: 1 closed and 2 open, with the help of which circulates air. In order to determine the input and output channels, turn on the motor and remember where the air flow is coming, and where it comes from. The closed tube is used just in order to change the oil. Working with a file, we wriggle in such a way as to avoid falling into the sawdust tube. We break the end, remove the oil and pour a new one, using the syringe for this purpose.

To seal the channel after replacing the oil, select the screw of the right section, we wind the sealant tape on it and screw into the tube tightly.

Motor together with the relay is fastened on a thick board, which will play the role of the foundation. We choose this position in which it was in the refrigerator. This is necessary because the start relay is extremely sensitively reacting to how it is posted. On it, it is usually the corresponding marking - stick to the right location so that the relay worked stably and correctly.


Krepim motor on a prepared board

The air tank is a necessary element that is necessarily entered into the compressor device. It must be designed for a certain pressure value so that the device worked correctly. We can use as a receiver, old capacity from decoyl fire extinguishers - they are durable and sealed.

Instead of a start-up valve, we get a threaded adapter on the receiver - use a special fum-ribbon for tightness. If the future receiver has foci rust, it is necessary to get rid of them by grinding and processing with special means. In order to eliminate corrosion foci inside, we fill the remedy and shake well. After put the water pipe with the use of sealant. We can assume that the homemade receiver is ready.


Old fire extinguisher Using as a tank for compressed air

Collect the device

The receiver from the fire extinguisher with the motor is attached to the base of the thick board. As a means of fixing, we use nuts, washers and studs. The receiver must be vertically. For its attachment, we take three plywood sheets, in one of them we do a cylinder hole. Two other sheets are fastened to a wooden basis and a plywood sheet that holds a homemade receiver. On the bottom of the wooden base, we screw the wheels of furniture accessories for the best maneuverability of the mechanism.

On the compressor's inlet tube, we wear a rubber hose to which the filter of cleaning for gasoline engines connect. Additional clamps will not be needed, since the magnitude of the air inlet pressure is relatively low. To avoid the presence of moisture and oil particles in the air flow, we put the oil-moisture-separating filter for diesel engines at the output. Here the pressure value will be high enough, so special clamps with screw fasteners should be used for additional attachment.

The diagram below shows how the self-made automotive compressor for painting cars is assembled.


Compressor scheme for car painting

Next, the filter for cleaning from oil and moisture is connected to the input of the gearbox, which we will be needed to join the pressure in the engine and the cylinder. We carry out a compound on the plumbing crossing on the left or right side. From the opposite side of the cross, we put a pressure gauge to control the pressure level in the cylinder. On the upper end of the cross mounted the relay for adjustment. The seal of all connections is performed using the sealant.

With the help of the relay, we will be able to submit pressure in the receiver, while ensuring the step of the mechanism. The relay is tuned by two springs, one of which sets the upper pressure boundary, and the second is lower. One contact with the supercharger, the second switch with the zero phase of the network. The second network input of the supercharger connects through a toggler with a power supply phase. The toggle switch will allow you to turn on and off the device from the power supply without removing the plug from the outlet. We carry out soldering and insulating all electrical contacts. After painting, our homemade compressor for the car will be ready for testing.


Homemade car painting compressor

We are experiencing and tighten the homemade compressor for painting cars

For testing to the output, we perform the connection of the collapse. Tumbler put in the off position and turn on the plug into the electrical outlet. The relay controller is installed on the smallest value and turn on the toggle switch. To control we use a pressure gauge. We are convinced that the relay is properly in the right moments open the network. With the help of water with a detergent, we check how sealed all the hoses and connections are.

Next, we release the container from compressed air - after the pressure drops to a certain level of the relay, the motor should turn on. If everything works fine, you can try to apply the apparatus for painting a suitable object. We look at the quality and make sure that the device works stably, and it can be used to work with the car.

The compressor is a multifunctional device that can be used for various daily needs, such as car tire swap, painting, and the like. But by virtue of the high-cost factory models, many owners think about an independent assembly of such an aggregate. The most common option to create a compressor with your own hands is the use of a refrigerator.

Benefits of the factory and self-made device

Before independent production of the air compressor from the refrigerator, it is necessary to compare it with a regular factory sample. This will help make the right decision.

Z. avodian and homemade devices have such differences:

Motor Restrictions

Not all refrigerator engines can work at the same conditions. Some of them have their own restrictions on operation.

Several modes of operation can be distinguished:

  • normal - from 16 to 32 degrees;
  • tropical - from 18 to 43 degrees;
  • subnormal - from 10 to 32 degrees;
  • subtropical - from 18 to 38 degrees.

But, despite this, combined modes occur, which include multiple operating ranges.

Thus, self-made devices are much easier and more efficiently factory, in particular, to work with air.

Disassembly work with the refrigerator

In order to scaffle a mini-compressor with your own hands, you must prepare for work. First you need to remove the compressor directly from the refrigerator. This is the initial stage. It is located in the back of the refrigerator from below. To remove it, you should prepare a set of basic tools: pliers, set of keys and screwdrivers (figured and ordinary).

On the compressor itself there are two tubes that are connected to the refrigerator cooling system. They must be bought off with bustacles or pliers. It is categorically forbidden to chop them with hacksaw for metal, because when sawing, small parts of the metal can get into the motor, which can lead to disastrous consequences.

After that you need to remove the start relay. It has the appearance of a regular black box with sticking wiring from it. First you need to unscrew the mounts, and then eat the wires leading to the fork. No need to forget to mark the upper and lower part of the relay so that there is no error when setting. It is also necessary to pick up all the elements of the unit fastening, they can also be used with the use of high pressure compressor with their own hands.

Checking performance

After disassembling the refrigerator and the compressor, it is necessary to check the performance of all parts. It is necessary to do this due to the fact that the item was removed from the old refrigerator, and it may not work for a long time. Therefore, it is necessary to do this. To begin with, flattering the tube pliers.

It is necessary to do this in order to pass the air through them. Further requires a previously removed relay to put back to the same position as it was before. No need to forget about the correct mounting relay. Top and bottom should be in their place. If it is established in a different way, the compressor may fail, which will lead to an incomplete breakage, or to burn.

Directly on the case of the relay there are wires. It is necessary to screw the wiring with a fork. A place in which the connection will be, it is necessary to oversee at least the power to avoid damage to the current. It is advisable to carefully suck the seat of the wires.

After that, turn on the compressor into the socket and monitor the efficiency of the unit. If it does not work, it means that the wires or the compressor does not work correctly. After turning on the compressor in the rosette from the tubes should go air. This will be an indicator of the device's performance. It is necessary to mark, from which tube the air goes out, and what it comes to.

Step-by-step assembly instructions

Before starting to work, all the necessary tools and materials should be prepared. Such kits may differ from each other depending on what the future owner of the compressor awaits.

In addition to the compressor itself, which is removed from the refrigerator, it is required to prepare nexther:

Then you should take the capacity of plastic of any sizes from three liters. In the upper part of the tank, you need to drill several holes for the compressor tubes. Then insert the tubes into the holes made and pour everything with a resin. The input tube should be located at a distance of 200 mm from the edge of the receiver. The output tube must be placed 10 mm inside the tank.

The receiver can be made of plasticAnd here nothing terrible will happen. But for greater reliability it is recommended to do it from a metal box. With this outcome of the events, there is no need to pour everything with a resin for good tightness, and the hoses are closed. Moreover, only a pressure gauge can be installed on the metal case.

To do this, in the receiver you need to drill a hole for the nut, which is necessary in such a hole to brew. Then there is an opportunity to screw the pressure gauge in the nut. After that, the work on the creation of a self-made compressor from the refrigerator is completed. For painting, you can use any materialsBut first can be cleaned and progress to avoid corrosion. After that, only you should attach the receiver to the base with a wire.

Some technical features

It is quite difficult to determine initially what will be the pressure in the compressor. This indicator may depend on both the brand of the apparatus and the period of its declared operation.

By the way, old structures can sometimes show even the best results than new and factory. It is not important that it is possible to assemble the device, but how to care for its condition.

Such works are usually in replacing filters (gasoline and diesel), as well as oils in the device. All homemade compressors are equipped with three copper tubes. Two are activated when installed. This is an input and output tube. The third was not touched. She is the very short one and sealed at the end. She is responsible for draining oil in the device. For maintenance it is necessary to cut off the sealed part, drain the oil, pour new and pour back.

Whether the compressor is repaired

As a rule, the relay when repairing needs to be squeezed. You also need to replace the oil in the device. If the compressor does not work after that, then there is no sense to take something, further repair needs to be stopped. It is better to throw such an autocompressor and make a new one. In addition, its price will not exceed one and a half thousand rubles.

By the way, an internal combustion engine with a supercharger can be used as a source material for the compressor. Thus, you can get a decent device with high power. Especially since the piston group is provided with a high power reserve. If there is an opportunity and desire, you can find it for a fairly low price in excellent condition. With this option, the ignition, intake and exhaust system must be deleted. For its successful work, there is enough lubrication of pistons, cooling systems and tightness.

Similar structures can be made from the gas cylinder. There are membrane compressors.

For two years I dream to acquire a compressor. Very useful device for a wide variety of works in the garage: swinging wheels, painting with gun, blowing engine parts and other things. On average, a simple compressor costs 10 thousand rubles, homemade cost 300 rubles, plus a bunch of trample, which was drank at home. An old compressor from the refrigerator, a gas cylinder, 10 bar pressure gauge, corners and tees with brass, plugs to them, nipple with a thread from moped cameras metallic, clamps, washers.

For the manufacture I used a compressor from the cylindrical refrigerator set horizontally. It has a capacity of 10l / min, it is very little compared to the industrial, but I don't have to let's lower the air under a low pressure of 3 bar, when in the receiver (I'll tell you further) the pressure is 8-9 bar.

For the receiver, I take a gas cylinder for 50l. The ahead of all gasoline merged with it. I tried to promote the crane, but whatever how to use, the crane did not succumb.

Since on the tap of the balloon, the left thread, I decided to make an adapter by 3 \\ 4 inches with the right thread. He took a high pressure hose and two adapters from 3 \\ 4 to 10mm with left and right threads. It turned out such an adapter

Ascended from the tees and corners a simple splitter and made a trial inclusion.

In 45 minutes, the cylinder scored a pressure of almost 9 bar, with the volume of the receiver 50l it is about 430l air

I scored a couple of times, and then up the bottom of the balloon, to remove the remains of gas and gasoline, after the resulting thorough assembly. The position of the cylinder is horizontal, the compressor mounting on top and installed all the wiring with the pressure gauge. Passed the clips planned on the nails welded to the cylinder. The compressor with the scheme connected the hose, attaching to the clamp

In the plug, drilled a hole, inserted nipple and put the rubber gasket on top. The plug squeezed on the crane, to the crane in a row two tees: one removal on the receiver, the other on the pressure gauge. Following the corner, to the corner of a coarse cleaning filter, to the clutch filter and the same plug as on the other side.

The filter had to be delivered to the oil that squeezes the compressor defended and did not fall into the receiver and tube.

It remains the case for small, fight legs and paint everything into one color. Front leg turned out one, behind two. All legs remnants corner

The automatic on the shutdown did not put the money for the purchase. The reducer to adjust the pressure for the same reason did not put. How will the money finish, but still enough and so.

To date, many different types of compressors are used in everyday life, for which a variety of gases are used. The greatest popularity has, which is also actively used by car owners for painting the machine or swing the wheels of the car, since it is less convenient to use a hand pump for the same purposes. Next, we consider how to make a compressor for painting cars and what is the procedure for its manufacture.

A small hole is cut in the chamber itself, it will later be the nipple for the electric or manual pump, which will be used for painting the car. At the input it should be done with the nipple, the second is inserted without nipple, the sprayer will be connected to it. The degree of compression of air is subject to accurate adjustment empirically. For this, the experimental part of the paint is sprayed onto the wall of the wall or any other. After the appropriate pressure level is detected, the pump is disconnected, and it is important to make sure that the pressure has not changed.

It is also important to take into account that the camera needs a dense fastening, because on the floor it will not be in a steady position. This option will make it possible to create a simple tool, with which the small flaws of the paint coating on the car are easily corrected.

Homemade compressor with your own hands. Option 2.

This case involves the use of a car tire with a chamber (or the camera itself), as well as the pump.

In this case, the use of a camera with a tire or without it depends on how much pressure you need to get from the homemade car. A small hole is cut in the chamber, in which another nipple is pasted (for this, raw rubber is quite suitable). One nipple should be equipped with a nipple for downloading air, and the second (output) joins the hose from the sprayer.

The pressure is adjustable using a barometer built into the pump. Next you need to spray paint on the wall to determine the required pressure. After that, it should be slightly unscrew the hose from the pump in such a way that the pressure of the sprayer does not significantly change during pressing. The exception is auto pumps with a built-in triggered mechanism, in this case the pressure will be permanent.

Production of complex compressors. Method 1.

For the manufacture of a complex compressor, any electric motor from the refrigeration device can be used (if it is overwritten, it is only necessary to use a piston mechanism).

To remove it, the case is made in two places with the help of the metal hacksaw, and then the fastening bolts are unscrewed and the stator and the pump with the rotor are removed.

Due to the fact that the rotor does not need it, it can be knocked down from the crankshaft if the design is equipped with a belt drive to the pump, then the crankshaft and the tail of the engine shaft are put on the pulleys with prismatic knaps that are fixed by M6 bolts.

Swipe grooves must be milling on all shafts, they can also be drilled using an additional sleeve with a hole with a diameter of 14 mm. It puts on top of the shank, after which the hole is drilled with a diameter of 5 mm exactly on the joint, then the sleeve is removed. In the section, key grooves have a semicircular shape, therefore the same form should be given to the knaps.

How to make a bed for construction?

The frame of the compressor can be made using two channels tied by cross-steel from steel plates on screws. The pump is fixed on the bed with four bolts with sleeves (their height can be selected directly in place), after which the engine is installed on the base plate.

The bed allows you to stretch the wedge-shaped belt due to its movement along the adjusting holes. If the air duct is quite long, then there is no need to apply the receiver - it can be used as a sump for oil.

Production of complex compressors. Method 2.

For this method of manufacturing a self-made compressor for painting, an empty five-liter cylinder for a gas stove is useful. Take the receiver, compressor and wheels, they must be fixed on the basis. The frame can be welded using rectangular tubes with a cross section of 40x25 mm, and in the absence of a pipe, you can use steel corners. To the base of secure wheels for the convenience of moving the structure. To adjust the pressure in a working compressor from the refrigeration device, visual control is needed using a pressure gauge.

It is also important to put the limiter at a suitable level. Nipple, pressure gauge and two fittings (one - on the entrance, the other - to the yield), are combined by the base on a solid metal bar with four drilled holes that are connected in one channel. In the holes you should cut the threads for each element. The block itself is fixed using two screws on the surface of the frame. Thus, compressed air is sent to the hose receiver.

In the gas cylinder used, you can leave a slightly shortened valve. From it, remove the valve, replacing it with a copper tube. From the inside it should be hoping a chlorine tube leading to the bottom of the receiver. With it, they are separated by pairs of moisture and oil.

In order for condensate to merge from the receiver, in the bottom it is necessary to make a muffled hole, the M8 nut is welded and the bolt is screwed. Welding can be started only after all the remnants of explosive gas are released. To do this, it must be filled with water. The second copper tube in the threaded hole M6 in the valve transfers air to the splitter, which transmits it directly to the consumer (on the paintopult, to the camera, in the ball, etc.) to start the engine, you can use the standard starter relay in advance attached On the frame. When painting with a gun, you can send whagi pairs to the hose using a fine filter of fuel purification for the car, it has the ability to delay moisture. Also before starting work, it is important to check if there is no condensate in the receiver. The finished compressor for painting cars is almost silent and very compact.

Production of complex compressors with their own hands. Method 3.

Compressor installation scheme. Click on photo to enlarge

The role of the main mechanism in this version is played by a two-cylinder compressor from ZIL-130. The carrier and generating detail will serve as a muffler from the car "Kraz". In the design, he is a receiver. It creates a simple frame from an angle of 35x35 mm, on which corners and mechanisms are located.

Under the receiver are several crossbar and the above-mentioned corners, they are connected to a frame with spills, self-orientaging wheels are attached at the ends.

Stage I.

To convert the silencer from the "Craz" to the receiver on the compressor installation, it is necessary to boil the inlet and outlet and the outlet, and then drill several holes on the M14x1 mm thread output, and screw two fittings on sealant. Initially, an intermediate receiver based on an oxygen cylinder is mounted.

His task is to absorb moisture and oils contained in compressed air. In order for it to work more efficiently, it is necessary to equip the threaded drain hole at the bottom of the device, after which it is overlapping it with a sealed plug. Bolon in this case can be deleted.

Stage II.

For compressor drive, a three-phase AC electric motor is used. Suitable power - 1kW with speed of 1380 / min. With the windings attached to it in the form of a triangle. It should be converted to working with the domestic network (voltage 220 V), but ideally the engine must be single-phase. In order for it to be easily launched and did not overheat, it must be equipped with a start-up and working battery of capacitors, and then connect according to the specified scheme.

A starting box can be used from washing machine. You should run the engine as follows: Press the Conferser's starting battery button, and then the main start-up on the switch. After the engine is picking up the nominal turnover, you can release the button of the start-up battery. Stop the engine can be button "Stop".

Stage III

The capacitance of the working battery of the capacitors should be selected such that the engine does not overheat even with long use. For one-cell engines, a capacity of 25 μF is suitable. The capacity of the launchers in this case should be between 70 to 100 μF. Basic criterion - fast rpm set. The breakdown voltage of all capacitors should be at least 300V. For better cooling on the motor shaft, an impeller is installed from six sowing blades. With the help of a clinoremable transmission, a rotation to the eccentric compressor from the electric motor is carried out by three times the number of revolutions.

Reducing the drive power consumed, and thereby facilitating its work, you can achieve, converting the compressor. For this, instead of a regular head equipped with only two outlet valves, it is necessary to install a duralumin plate on four valves (two intake and two graduation). The compressor is connected to the handout and receiver using pipelines. They are made of aluminum with a passing diameter of 6 mm. It is fixed by standard aviation fittings, tees, coolers and cape nuts with sleeves. The dispensing box can also be made independently.

For this, the aluminum bar is taken with a unilateral deaf longitudinal hole with a diameter of 10 mm. The receiver tube is joined to it through the fitting. It is also necessary to make three more holes: one side and two tops. In the same upper opening, a pressure gauge is installed, in the other - a safety valve. It should be adjusted at the limit pressure of 4 kg / cm2 (4 atm). In the side opening mounted nozzle for the output of compressed air.

Classical Layout of Nodes and Parts

This layout is used in all domestic household devices. As a base for nodes and parts, a large and bulk receiver is used. It is also used for sparky motor-compressors. Under it adapts an empty cylon from under liquefied gas by 50 liters. Such a balloon is designed for 16 atm.

Stage I.

The remaining propane is removed from the cylinder, for this, the valve is unscrewed, the balloon is set "on the ass", and above it is a water reservoir. Using a thin rubber hose with a metal tube at the tip, the balloon is filled with water. She displaces gas and all sorts of fluids from it, contained in propane to be able to detect gas leakage. A supporting ring is removed from the cylinder. First, it is possible to cut the cross-crosswise, and then beat the edges until they slam down across the welded seam. Such a procedure will make the type of product more aesthetic.

Stage II.

Before starting welding, the cylinder must need to put "on the ass" and pour to the top to the top. Couples that are formed by welding will be cooled during the rise through water. From above cylindrical, horizontally, the receiver should be placed the supercharger. It consists of paired motor-compressors on a submool frame made from angle of 30x30 mm, the relay, starter and terminal bar are placed there. A handle is welded on one of the edges, it can be reached from a plumbing pipe with a diameter of 20 mm, this will help in moving the unit.

To do this, you can also bring the chassis, under the handle of one edge, set the drain in the form of an inverted letter "P", on the other edge - similar, but from the chassis. The first is manufactured using a steel corner of 30x30 mm, the second (optional) is from angle of 40x40 mm. It should be accelerated by the crossbars on the edges, the corner brackets designed for holes under the axis of the wheels. On the inner side of the brackets, it is necessary to prigerate the nuts M8, with their help the axes from identical bolts M8 are attached.

Stage III

On the side of the balloon, a hole with a diameter of 6 mm is drilled. The input fitting is welded in the form of a small cut pipe with a diameter of 10 mm. One of the troops of the tee is attached to it with the help of the hose, two other discharges are combined with such oxygen high-pressure oxygen hoses with lean nozzles of all motor-compressors. On connections, tees, hoses and fittings are dragged with clamps.

To remove water and oil from the cylinder in the process of using them, you need to welcome a short threaded fitting at the tip at the bottom of the cylinder. A hole on the inner diameter of the pipe is drilled in the wall, and the fastening itself is "jamble" with the help of an injected tube. The brass valve on the cylinder needs to be revisted, so at the base of the part it is necessary to drill the hole and cut the M14 threads in it. There should be screwed the nozzle, and to attach a pressure gauge to it with a special nut. The second nozzle must be screwed into the outlet of the valve, then attach the consumer hose to it.

The homemade compressor, in particular, its electrical part, in this case consists of a starter and starting windings taken from the washing machine, the disconnection relay and terminal block connections. The latter can be taken from the fluorescent lamp of daylight. All the above is mounted on the board from five millionth textolite and is attached to the tip of the cylinder. One end of the board must be opened on the frame of the frame of motor-compressors, the second - on another support rack, welded to the surface of the cylinder.

Power is powered from the AC household network (voltage 220V). The electrical circuit and separate starters, depending on the amount of consumed compressed air, allow you to include both Motor Compressor or one of two. It will create a high-quality and durable aggregate with your own hands. Below, in the diagram, the compressor with a crane from the design of the liquid cooling of the Moskvich car instead of the valve is depicted.
