The cleanliness of the car must be monitored so that the accumulated dirt containing aggressive chemical compounds does not destroy the paintwork and metal parts of the car. In order not to waste time and money on visiting a car wash, you can design a pressure washer yourself.

1 How a pressure washer works - construction and other details

The advantage of high-pressure washing is that the car body, engine compartment and bottom can be washed from dirt with a directed water jet. Such devices are installed on professional car washes and cost a lot of money. Great alternative device Karcher can become a homemade sink. The principle of operation of a pressure washer is the same as that of a conventional car wash.

First, air is pumped into the tank in which the water is located using a pump or pump. This creates excess pressure in the water tank. Water is supplied to the outside through a rubberized hose when the trigger of the watering gun is pressed. The pump is needed to pump air into the tank. You can use a car or plunger pump. The convenience of the plunger is that it belongs to the hydraulic devices of the metered type. According to the selected proportions, the plunger unit mixes water and detergents, and then delivers the mixture under high pressure.

A homemade pressure washer has several advantages:

  • the parts necessary for assembly can be purchased in stores or adapted from improvised materials;
  • assembled quickly and easily;
  • easy to use at home;
  • it is possible to increase functionality by installing additional equipment;
  • the main plus is low cost compared to professional counterparts.

2 Selection of electrical components - motor, pump and gearbox

The main element of the sink is the engine, which will supply a jet of water. You will need a powerful pump that could create pressure up to 150 atmospheres with a capacity of 15 liters per minute. In normal operation, it should use 80-90% of its rated power. It is desirable to select a pump with a power supply of 220 or 380 V. It can be made from an automobile compressor or a compressor from a refrigerator. It will cost less, but the performance will be lower.

When choosing a unit that supplies water, you need to pay attention to the materials from which it is made. It should have a high strength ceramic or metal piston. To make the design more durable, the head should be made of brass or bronze alloys. For a home-made sink, a low-power engine is suitable - 200-200 watts. It is better to choose a single-phase motor: it is safer to connect it, and it is more economical.

The design of the car wash can include a gearbox and a condenser. The capacitor bank increases the number of revolutions, which will increase performance. Installing a gearbox in the form of a belt drive with one stage will make it possible to balance the load and speed between the pump and the motor. To connect the motor and pump, you must purchase a coupling that will ensure the safety of these components. It is better to buy a soft coupling, with which it will be possible to compensate for small deviations between the shafts.

3 Additional materials for homemade washing

A necessary element is a container for holding water, which will be used for washing. It should be from 5 to 30 liters in volume so that you do not have to fill it often. As a container, you can use a plastic canister or bottle. It should be noted that there are no seams on its bottom. A fine mesh filter can be installed at the inlet or outlet of the tank, which will protect the pump from debris.

Hoses should be selected plastic or rubber with reinforcement, about 5 meters long and with an average diameter. Connections must be securely sealed. This is ensured with the help of clamps and sealant, which is applied at the joints. It is desirable that the design be collapsible and maintainable, so threaded connections should be used whenever possible.

Water is supplied through the gun by pressing the start key. When choosing a pistol, pay attention that the key works smoothly, without jerks. To facilitate the washing process and create a jet of water of a certain shape, you need to purchase various nozzles: rollers, brushes of different hardness, sprayers. All parts of the installation are mounted on a frame made of round and shaped pipes. Wheels can be attached to the down tubes for easy transport. You should also provide stops for fixing the installation and handles for moving.

If you need to wash the car at a low temperature, you can make a foam generator with your own hands. Using such a device, you can evenly apply fine-grained foam from the washing solution to the car, which allows you to qualitatively wash the surface from dust and adhering dirt.

To obtain foam, water mixed with detergents is sprayed with an air stream that passes through the installed channels, and then mixed with a foaming tablet in a special unit. The flow is regulated by means of special plates.

4 Features of manufacturing and operation - assembly in 4 steps

Having prepared all the necessary components of the mini-sink, we combine them into a single design:

  1. First, we prepare a tank to connect the pump and fill in the washing liquid. In the lid of the prepared container, we make a hole for the nipple through which the pump will pump air and water with detergents will be poured. If there are gaps, they must be treated with sealant.
  2. Next, at the bottom of the tank, we prepare a hole for connecting a watering hose with a gun. We fasten the coupling from the inside and perform a thorough sealing.
  3. When the tank is ready, we fix the main installation to it with the help of soft connections. We seal all connections using a special sealant.
  4. From below we carry out a watering hose with a gun and check the performance of the car wash.

For safety reasons, the system must be grounded. To check, turn on the installation in the mains. In this case, you need to ensure that water does not get on the wires. If the assembly is done correctly, then after pressing the trigger, a powerful jet of water will begin to beat from the gun. If there is no pressure, then the seal is broken, you need to check all connections.

In order for the installation to serve you for a long time, you need to follow a number of rules during its operation:

  • Before each use of the car wash, check the tightness of the connections.
  • Do not use strong water pressure very often, as this puts a large load on the pump and leads to rapid wear.
  • For efficient operation of the mini-sink, it is desirable to use various nozzles.
  • If filters are installed at the outlet of the tank, they must be cleaned of accumulated dirt and debris after using the unit.
  • To protect against power surges, the installation should be equipped with a battery.

Today, you no longer need to waste time and effort to deal with dried-on dirt and clogged dust. Every year, new modifications of pressure washers appear on the market. These devices wash not only cars, but also windows, walls and doors of houses, all kinds of household utensils that are difficult to clean with a brush and a rag. Strong water pressure is much more effective to cope with this task. The presence of such a device at home will save money that will be spent on washing the car in the service, while water consumption will be minimal.

Internal washing device

The main parts are the engine and the pump, they create the necessary water pressure. It is recommended to use a single-phase electric motor with a potential of 220 V, it is easily accessible and safe.

To make the case, choose a strong material, metal or durable plastic. But even when using a wear-resistant case, it is not recommended to use a sink for more than three hours in a row. This will lead to a quick breakdown.

A wide variety of nozzles for hoses are available, they serve to facilitate cleaning - different stiffness brushes, standard sprayers and soft rollers. If you buy a pair of these nozzles, you can significantly increase the functions of the sink, use it as a steam cleaner (requires a heater) or an automatic mop.

Internal pressure

The more pressure is created inside the body, the stronger the jet of water from the hose will be, which means that the dirt will fall behind faster. Pressure must be set carefully, high pressure water may cause dents in the vehicle or damage fragile parts. Manufacturers recommend setting the pressure in the range of 150-170 bar, 100 bar is enough to clean the machine.

If a jet of water fails to clean, purchase a nozzle for a hose, a turbo cutter. With its help, you can wash discs, tires and remove accumulated dirt in the cracks. To use a turbo cutter, you need 160 bar.

Electric pump

Before buying a pump for designing a sink, you need to choose the right device. The material from which the pump is made will determine its durability.

The plastic pump will soon fail. Such a pump it is not recommended to use more than 20 minutes at a time. Reliable, but expensive are made of brass, as this material does not corrode.

How to use the mini sink

In order for the sink to work for a long time without breakdowns, the following rules should be followed:

  1. Before starting operation, be sure to check the functionality of the sink.
  2. Be sure to change the filter after each use.
  3. If the power source is unstable, install a battery in the sink.
  4. If necessary, replace damaged parts in a timely manner.
  5. Install surge protection.

If you follow all the rules, your sink will last a long time.

Homemade car wash

If you set out to make a sink with your own hands, you will need the following materials:

Canister volume selection depends on the purpose for which a home-made pressure washer will be used. A five-liter canister is enough for a car.

Choose a hose that is flexible and durable, it should not break. The most suitable option would be a hose with a nylon braid and consisting of several layers. You can't skimp on this part.

The pump can be used both foot and electric. It is more convenient to use an electric pump, you will not have to do unnecessary physical work with your foot. However, the cost of such a pump will be several times more expensive.

Coupling and fitting choose at your discretion, the main thing is that they have a tight connection with each other.

In the canister, make a hole suitable for the size of the coupling. Next, insert the coupling into the hole and screw in the fitting. In order to maintain the desired pressure in the canister, all structural details are connected to the sealant.

The lid on the canister must be solid and durable.. For higher tightness, put a rubber gasket on the bottom of the lid. Then drill a hole in it and insert the fungus of the tubeless tire.

The canister is tightly twisted with a lid, and a cord from the pump is connected to a pre-embedded fungus. The hose is attached to the hole in the canister with a fitting. The device is ready!

The principle of operation of such a device is simple: with the help of a pump, air is supplied to the canister (you do not need to fill the canister with water to the brim). The pressure created will displace the water when the gun handle is pressed.

If a home-made device will be used in cold weather, it should be equipped with a heating element. For such a sink, a canister with a large volume is required, it will lose its mobility, but with the help of hot water, the dirt will be cleaned much faster and more efficiently.

The cleanliness of the car is not only an aesthetic indicator, but also protects the product from negative environmental factors. After all, adhering and dried dirt may contain aggressive elements that damage the paintwork. Also, long-term and regular pollution of the body can lead to irreversible damage to the metal, up to through corrosion on individual elements.

In this case, a regular visit to a car wash or home water treatments saves. But in the second case, you need to buy a washing device or a car wash must be made with your own hands from improvised means. Prices in stores generally start at 5 thousand rubles. The upper threshold may not stop at 20 thousand. Therefore, we will do it ourselves.

Pump and electrical part

The main part of any water supply unit is the pump. For our product, it will need a sufficiently powerful one, capable of developing a pressure of at least up to 150 atmospheres. When choosing a finished pump, it is necessary to take into account the materials from which the working units are made.

Preference should be given to products with a high-strength metal or ceramic piston.

It is desirable to select an electric motor with a voltage of 220 V. Reliable start is provided by an additional capacitor unit. A higher RPM will provide more performance.

You need to be aware that a pump that is too fast with a high number of revolutions can lose power at maximum operating speed and is subject to intense wear.

Consumers of 2-3 kW and rotation up to 2000 rpm are considered optimal.

Rotation transmission

A self-constructed high-pressure washer must have the necessary safety elements in the circuit to preserve important components. This link is the coupling connecting the pump and the engine.

It is desirable to install a coupling that can compensate for small axial misalignments between the shafts.

You can also install a belt drive with one stage. Such a gearbox will balance the speed and load between the engine and the pump. The gear ratio is selected based on their required output parameters in terms of rotation frequency.

Reservoir and performance regulator

The mini sink must be equipped with a sufficient water tank. A tank is suitable, which can be additionally powered from a permanent source of water: a water tap, a deep well or a small water tower.

What to make a sink

It is advisable to install coarse and medium filters at the inlet to the tank. So, unnecessary rubbish will not get into the pump and will not interfere with the operation of the entire system.

Car shampoo or other approved car cosmetics can be added to the main water tank. The process will run more efficiently.

The performance regulator is usually combined with an unloading autovalve, which redirects unused pressure back to the tank, reducing the load on the pump.

External elements

All units are mounted on a frame made of shaped or round curved pipes. Often, a pair of wheels are attached to the down pipes to help transport the unit. Stops for fixing and a handle are also installed so that the entire structure can be moved.

The appearance of a do-it-yourself car wash

For a high pressure hose, you can use a plastic or rubberized reinforced hose. Be sure to ensure the tightness of the connections using high-quality clamps or hydraulic seals.

The design must be collapsible and maintainable. Therefore, it is desirable to use threaded connections where possible.

Also, in places of contact with water (fittings, valves), low-corrosion alloys should be used: brass and bronze.

Car wash scheme

Direct water supply is carried out through a gun with a nozzle installed in it. It bears a visual resemblance to a pistol at a gas station. A jet of water is formed only after pressing the key. This method helps to save the prepared working fluid with consumable additives. You can simply buy a gun at any hardware store.

Operation of a do-it-yourself sink

Details for assembling the sink

When using, you need to follow a few tips:

  • periodically it is necessary to inspect the connecting nodes and tighten the threaded connections with a wrench;
  • the filters installed in the device need to be inspected before each connection so that the throughput does not decrease;
  • the electrical part must be grounded to avoid accidents during operation, for this a cable with three copper cores is used, and the plug must have a ground terminal;
  • during the washing process, it is not necessary to fix the jet at one point on the machine body for a long time, so as not to damage the paintwork with strong pressure.

Foam generators for car wash

A device for high-quality contactless washing is called a foam generator. With it, you can completely envelop the machine with small bubbles of washing suspension and carry out high-quality cleaning of the surface from dust, dirt and adhering small particles.

The process of foaming with a home foam generator

Do-it-yourself foam generator for washing can be made even in the garage. It is necessary to be patient and prepare all the nodes and elements.

The principle of operation of the foam generator

The device performs two main functions in the car wash process:

  1. the formation of fine-meshed foam from prepared reagents;
  2. uniform application of foam on the desired surface of the vehicle.

Homemade foam generator

To perform such a process, a jet of water mixed with car cosmetics (shampoo or other specialized preparations) is sprayed using an air stream passing through installed channels, and together form a coarse foam.

The mixture is then passed through a blowing tablet block. Now such a mass can be applied to the surface.

The flow control plates provide a fine atomizing spray to distribute the working foam to all the irregularities in the exterior of the body.

The difference between homemade equipment and professional

The quality of professional washing with a foam generator can be higher than when using a device made by yourself. For this, there are several criteria that determine the final result.

The main parameter is the size of the formed foam. An important characteristic is the homogeneous structure and the minimum bubble diameter.

When using professional sinks, specialized industrial shampoos are used.

Also, professional equipment allows you to pump a significantly greater fluid pressure than that which can be achieved in garage conditions. This reduces the consumption of detergents.

But with all these factors, the result of self-washing turns out to be quite worthy, especially since the final price for one session speaks in favor of a home-made device.

Self-made foam generator

Making a foam generator will require the creators to stock up on a set of keys, a grinder, a pre-purchased repair kit with spare parts for a professional installation, consisting of a nozzle, a gun, a compressor, and a flushing hose.

How a car wash works

In addition to the listed elements, it is necessary to take an inch pipe about 70 cm long. From it you need to make a filter. To do this, fill the cavity with pieces of fishing line. It is advisable to use it of different diameters, so foam will form more efficiently.

After stuffing, you will need to install metal filters on both sides to prevent pieces of fishing line from falling into the shampoo container.

The principle of operation of the foam generator

Next, threaded plugs are placed on both ends of the pipe. Now a T-junction is screwed to one of the plugs. A compressor is screwed to such an adapter, and a hose from the liquid reservoir is screwed onto the second thread. The free end of the line tube will be the outlet for the foam. A hose is attached to it through a fitting for spraying the finished foam.

You need to know that the quality of the resulting foam depends on the quality of the stuffing in the tube with the fishing line.

You can achieve the desired result by changing the packing in the tube with fishing line. It is also allowed to empirically select the required length of such a pipe and the texture of the stuffed fishing line.

How to make a pressure washer

Over time, high-pressure washers, mainly used for cleaning cars, have become more widespread in domestic markets. Using a similar device, you can wash both the body part and the bottom and engine compartment. The undoubted advantage of this device is that a precisely directed jet is used to remove dirt from the surface of the car without the use of a powerful water pump. A very profitable idea is a do-it-yourself pressure washer, which allows you to significantly save money spent on periodic washing of the car. If we take into account domestic weather conditions, when at any time of the year there is dirt on the roads in any of the states of aggregation, then such a wash will pay off very quickly.

The easiest way to do your own washing is to use an air compressor.

Basic principles for creating a sink

The main functional element of the sink is a pump that meets a number of requirements. So, it should show high functional performance per unit of time and work in normal mode at a pressure of about 100-200 bar. Many electrically driven plunger pumps have these characteristics. When choosing a pump for your future sink, special attention should be paid to the material that has become the basis for its working part. The best option is if ceramic or durable metal is used for the pump pistons. The best option for the manufacture of the cylinder head is brass. Durable components are the key to a long service life.

The most profitable would be to purchase a pump with a working capacity of about fifteen liters per minute and a pressure of up to two hundred bar.

It turns out that such a pump in normal operation will operate at 80-90% of its maximum power.

The choice of parts for washing

When choosing an electric motor, you should pay attention to models that have a power supply of about 220 or 308 volts. In the event that the pressure washer will be used at home, it is advisable to use a single-phase 220 volt connection, as it will not entail additional costs and meets all safety requirements. To ensure optimal starting of certain motors, it is desirable to use additional capacitor banks. So, the performance of the pump directly depends on the number of engine revolutions: the higher their frequency, the greater the performance.

But it should be borne in mind that working in this mode can negatively affect its resources. Do not give preference to too high-speed models. The maximum allowable rotational speed in this case is up to two thousand revolutions at a power of two or three kilowatts.

A high-pressure washer of a certain design makes it possible to provide the necessary pump performance when using a single-stage gearbox operating with a V-belt drive. Their gear ratio depends on the parameters of the pulleys (slave and driver). An equally important role in the activity of gearboxes is played by the characteristics of the distance between the axes of rotation.

A coupling is usually used to ensure the fixation of the pump and motor. The most suitable option is a soft coupling that can compensate for the minimum axial misalignment of the shafts and act as a safety element in case of a gearbox or pump jamming.

A very important structural element of any sink is a water storage tank. In order to ensure the maximum performance of the pump, it is necessary to use a certain volume of liquid. To do this, it is possible to use a special liquid tank capable of replenishing from the water supply network. Be sure to install a filter element at the outlet from the tank (it can be an ordinary small network), designed to clean the liquid from dirt particles and prevent blockages from entering the pump. To enhance the washing effect, a special or conventional detergent can be added to the liquid.

Do-it-yourself car wash should have a pump performance regulator in its design. Typically, this device is connected to an automatic unloader valve capable of redirecting the liquid back to the tank in an emergency so that no harmful load is placed on the pump.

In order to fix all the structural elements of the sink, a special frame is used. For its construction, you can use hollow curved pipes. To ensure the convenience of its use, you can fix a pair of small support wheels in its lower part and make an emphasis to give stability to the structure during use. One of the ends of the frame can be equipped with a special handle designed to transport the sink around the yard or garage.

The main structural element of a homemade sink is a water tank. In order to ensure maximum pump performance, a certain volume of liquid must be used.

One of the most important elements that make up a do-it-yourself sink is high pressure hoses. A standard not too thick reinforced rubber or plastic hose can act as a sleeve. It should be borne in mind that all structural connections of hoses must be made in compliance with the conditions of tightness, on the one hand, and not be afraid of corrosion and easy to disassemble, on the other. To equip the fasteners, you can use fittings or threaded bushings made of hard aluminum alloys or brass. For this purpose, it is possible to install bayonets.

When building a sink with your own hands, you must also pick up a gun equipped with a nozzle. Thanks to its shape, an imitation of the shape of the working jet is obtained. Actually, in appearance it resembles a pistol used at gas stations. In order to start the water supply from the nozzle, press the handle. This is a definite plus, as it allows you to save a large amount of water: the liquid is supplied only when it is needed, when you press the pistol grip. It is quite problematic to make a shut-off valve with your own hands; the simplest and most reliable option would be to purchase a ready-made tip.

The high pressure pump from a car washer is perfect as a compressor for a car wash.

When performing high pressure, care must be taken to create grounding. For this purpose, a three-core flexible wire equipped with double insulation is often used, and a plug supplemented with a ground terminal. It should be borne in mind that the power outlet also needs reliable grounding using a circuit.

Periodically, it is necessary to inspect all connections and fasteners and tighten them if necessary. Regularly clean the filter element of the tank from accumulating debris.

It is undesirable to use a jet of water with high pressure too often - this causes an excessive load on the charge pump and damages the car's paintwork. It is recommended to apply pressure that can contactlessly remove the main layer of dirt on the surface to be treated, and already with the help of a brush to manually get rid of the remaining dirt.

The principle of operation of a pressure washer

Thanks to the devices operating at high pressure in the range of 120-150 bar, dirt can be removed from almost any surface. It is worth being prepared for the fact that a small layer of plaque will still remain after such processing.

Any sink must have a device that regulates the nozzle. By adjusting the position of the nozzle, you can change the pressure or shape of the jet. The nozzle can be equipped with foam generators and additional mud cutters.

If you wish, you can design a sink with your own hands that can be fed not only directly from the water supply, but also from a special reservoir - for example, barrels of water. To improve the pressure in the sink, you can put the barrel on a slight elevation.

In case of a power outage or use of a sink away from outlets, you can equip the device not only with a water tank, but also with a powerful battery.

The undoubted advantage of sinks of this kind is the great water savings, in contrast to manual washing.

Washing device

Inside the high-pressure washer, there should be an engine that provokes the rotation and opening of the remaining parts - the valve, washer or sprayer. The result of its work is the untwisting of the washer and the movement of water along the sprayer according to the forward-return trajectory, as a result of which water enters the sprayer valve. The result of the action of many mechanisms is the formation of a powerful pressure and water supply.

It is advisable to choose a housing for washing from impact-resistant plastic. The same requirements apply to the hose connected to the sprayer, as it will have to interact with a strong water pressure.

No matter how durable the sink materials are, it is highly recommended not to use it for more than two consecutive hours. Too long a cycle of operation can lead to rapid wear of the component parts and shorten the life of the device several times.

If you equip the sink with additional nozzles, it will be able to perform the functions of household appliances. When using additional nozzles, the sink can be used both for washing a car and for cleaning roofs, facades and floors.

The main parts of a pressure washer

A do-it-yourself sink consists of the following elements:

  • durable wear-resistant housing;
  • engine running on gasoline or electricity;
  • pump operating at high pressure;
  • containers for water and detergents;
  • additional nozzles;
  • water filters;
  • hoses.

The principle of operation of a homemade sink is extremely simple. From the water supply or a special container, after connection, water enters the sink container and is pumped using a pump. In the maximum load mode, the washer operates at a pressure of about 160 bar. For comparison, a stream of water from a conventional tap is supplied at a pressure of five bar.

The next step is to supply water through a hose to a gun with a nozzle. It is advisable to equip the gun with a special nozzle that allows you to change the nature of the water flow - from a concentrated jet to spray. The nature of the water supply should be determined based on how the surface will be cleaned. For example, to cover a large area (veranda area or car body), a fan jet would be the best option. In order to remove fragments of stubborn dirt, it is advisable to use a point version of the water supply.

The role of additions can be a nozzle with a rotary nozzle, a rotating brush and much more. The main advantage of using nozzles is non-contact cleaning of the surface, which significantly reduces the risk of damage to the paintwork of the car body or the decorative surface of the facade tile.

When choosing parts for washing, you should not chase after achieving maximum power. A sink used at home can function normally at an operating pressure of 100 bar. Moreover, for a person who has not previously encountered such a technique, it will be problematic to manage a high-pressure washer.

The household goods market is replenished every day with new products that are designed to make life easier for a person. And here, far from the last place is occupied by a high-pressure washer, which makes it possible to significantly facilitate the process of washing a car, paths, shop windows and much more. A powerful jet of water is able to clean dirt even in the most inaccessible places, to cope with old dirt on any surface.

But at the same time, it is worth noting the fact that, due to the high cost, not everyone can purchase a device of this type, and therefore some craftsmen make it on their own. But how can you do a high-pressure washer with your own hands, we'll talk in this article.

The content of the article:

How to make your own pressure washer

Pump and electrical network. For any water supply device, the pump is the basis. And in our case, it should also be powerful enough (from 150 atmospheres).

When choosing a pump, special attention should be paid to the working units, that is, the material from which these products were made.

If possible, we choose a product with a high-strength metal or ceramic piston. In this case, the block head is recommended to be selected from brass or bronze alloys. This design can last much longer. The resource between repairs is quite high.

A speed of 15 l/min will be sufficient for the pump.

It is recommended to choose an electric motor with a voltage of 220 V. An additional capacitor unit can provide a reliable start. Higher speeds also ensure greater productivity. But at the same time, a pump that is too fast at maximum operating speed is subject to intense wear.

The best option is a consumer of 2-3 kW and rotation up to 2000 rpm.

A home-made high-pressure washer, in order to preserve important nodes in the chain, must also have safety elements. This link is the coupling connecting the pump to the engine.

If possible, we install such a coupling that could compensate for small axial misalignments between the shafts.

You can also install a single stage belt drive, which will balance the speed and load between the motor and the pump.

The subordinate number is selected based on the required parameters for the frequency of rotation.

Reservoir and performance regulator. The minisink also needs a water tank. In this case, you can use a simple tank, which, if necessary, can also be powered from a permanent source of water (well or water tap).

To exclude the possibility of various debris entering, it is recommended to install coarse and medium filters at the inlet to the tank.

We also add shampoo or other approved auto cosmetics to the main water tank. In this case, the washing process will be more efficient.

As a rule, the pump has a capacity regulator combined with an unloading autovalve that redirects unused pressure back to the tank, reducing the load on the pump.

External elements. We mount all elements on a frame, which can be made of profile or round curved pipes. For the convenience of transporting the unit, a pair of wheels can also be attached to the down pipes. In addition, we also install stops for fixing and a handle.

How such a mini sink will look like can be seen in the photo.

For a high pressure hose, you can use a plastic or rubberized reinforced hose. Be sure to ensure the tightness of the connections using high-quality clamps or hydraulic seals.

The fittings and valves used must be made of low-corrosion alloys: brass or bronze.

Water will be supplied through the gun from the nozzle installed in it. Visually, it looks like a pistol from a gas station. A jet of water will be formed after pressing the key, which in turn will also save the working fluid with consumable additives. You can buy a pistol of this type in almost any hardware store.

  1. Periodically inspect the connecting units, and, if necessary, tighten the threaded connections with a wrench.
  2. In order not to reduce the throughput of a home-made mini sink, before each connection we inspect the filters installed in the device.
  3. To avoid accidents during operation, it is mandatory to ground the electrical part. Therefore, the plug used must be with a grounding terminal, and the cable must be copper, three-core.

How to make a foam generator with your own hands?

You can make a foam generator at home. Of course, in terms of functionality, such a device will lag behind its counterpart, but in everyday life it is difficult to overestimate its benefits.

Of the tools we need:

  • Set of wrenches;
  • Roulette;
  • Bulgarian;
  • pliers;

1) .We use an inch pipe with a length of about a meter. We hammer the front part of the product with a plastic washcloth, the purpose of which will be the formation of foam.

2) . For one of the edges of the pipe we make a plug, we also screw a special tee here. After that, we connect a tap to the foam generator to the inlet hole.

3) . On the other side of the pipe, we install a valve through which compressed air will be supplied from the automobile compressor.

4) . We combine the second pipe outlet through a special fitting with a foam hose. To prevent the washcloth from getting into the tube, we also install a special filter. In this case, the filter element may have large sections.

A diagram of a foam generator of this type is presented below.

Please note that the density of the produced foam depends on the length of the tube and the density of its stuffing with a washcloth.

Any container that can withstand the pressure of the compressor is suitable as a liquid tank.

How to properly wash a car with a car wash?

Hand washing is the so-called easy option for cleaning a car from dirt. But as practice shows, in this way it is possible to partially clean the surface of dirt. Another thing is the use of special technical means - car washes that supply detergent and water under high pressure.
