How to get rid of the noise of the generator. Additional noise insulation generator

As was established in the process of numerous studies, the noise from the working generator is transmitted in two ways: by air and through vibration when contacting other surfaces.

According to the data, the dieselgery installation makes sounds with a power up to 100 dB. If you compare this level with other objects, then on average it is equal to the noise of five cars passing in a kilometer from your home. To reduce its companies have been developed various recommendations, the integrated use of which allows you to achieve a decrease in noise five times! But for this you should block all the ways to distribute sounds from the working installation.

Experts allocate two such groups of methods:

Global noise suppression methods

1. Installing an aggregate in a separate building

This technique is optimal for large enterprises with the possibility of using separate buildings or cash For the construction of a new building. To implement this project, it is best to use in the construction of an object of a sandwich panel that have increased sound insulation. However, for a domestic consumer, this method is not suitable due to serious financial investments.

2. Installing the unit in noise insulated room

This method is applied much more often due to a simpler implementation. In adapted installation of a diesel-generating device, a complex of finishing works to increase its soundproofing characteristics is carried out. A non-combustible mineral wool can be used as a primary materials: it is capable of a quarter to reduce the noise level. Also used foam or lining. The principle is based on the properties of the air in which sound waves Fucking. So the thicker will be the airbag between the walls of the room and internal space With the unit placed in it, the lower the noise level.

Speed \u200b\u200bnoise suppression methods

The diesel generating unit has several elements that are sources of sounding device sounds. The use of additional soundproofing devices in these zones will significantly reduce the noise level.

1. Reducing mechanical vibration

The design of the power plant in the process of work creates a vibration that is transmitted through the floor walls and causes noise. To reduce these mechanical waves The manufacturer uses special shock absorbers.

However, for more efficient noise cancellations, there are sound insulation covers that create an additional sound barrier around the equipment. It is manufactured such a device in factory conditions with all the necessary options. Thanks to the effective noise reduction, the diesel generator can also be operated on the street, but only under the conditions of the optimal temperature regime.

Casing design:

• steel case, covered from inside with non-combustible materials;
• the presence of technical openings and the door with locks;
• viewing hole to access the control panel;
• muffler with a vibration resistant adapter;
• special noise reduction chambers from intake and outlet.

For installation on the street in order to suppress noise and protect equipment from atmospheric precipitation and low temperatures, all-weather containers are used. Their main difference from noise insulating housings is easier access to maintain the unit.

Besides:

• lack of impressive financial costs;
• convenient transportation without complicated mounting work;
• excellent opportunities for modernization and dustcompletion;
• no need for a separate building or premises.

Containers are also manufactured in factory conditions and have various sizes. In accordance with this, there are two types of enclosures:

• Containers with external service or minicontainers
• Containers with internal maintenance or full-format

Full-formats have access to the structures inward, where various serving or repair activities are carried out. There is no access to the mini-container.

2. Reducing noise with silencers

Installing the silencers is simple enough, in some models it may be provided for installation not one, but at once several "plugs". According to the principle of operation, the generator silencer is absolutely identical to the car. It reduces the sounds of the release system due to the dispersion of energy in special chambers and through tubular partitions, thereby delaying sound waves, which become the cause of resonance. Correctly selected this device, depending on the type of device and its power, is able to reduce the noise of the generator by 49 dB.

The silencers have a different degree of noise reduction and are divided into devices:

• Industrial with low degree. Optimally suitable for use in production areas where general level noise and without that high.
• For populated areas with a moderate degree. Allow you to reduce the sound level by 29 dB.
• Critical with high degree. It is necessary to apply in sleeping areas.

In the quality of this method, you can call insignificant financial costs for its execution, installation flexibility, as well as various solutions At the place of installation.

Important: The length of the entire exhaust system together with the silencer should not exceed three meters so as not to create a high return pressure of the spent gases. It is necessary to provide for additional heat isolation Devices, limit contact with it combustible materials.

3. Use for noise reduction of ventilation gratings

According to the parameters of the diesel generating device, the air flow in its ventilation holes reaches a speed of 3.5 m / C and is characterized as a moderate wind. At the same time, the passing air flow also creates various noises to which the sound from the running fan is added, ten times the buzz of a computer cooler.

Special ventilation grilles are used for noise reduction. They can be performed in different optionsThere are devices for mechanical or autonomous discovery of blinds, with air flow orientation systems.

Important: These air grids or attenuators should be selected according to the power of the dieselgery installation. According to the manufacturers recommendations, the device must have in open video minimum 50% free space, good profile Airflow with low resistance to his access.

If blinds running offline are installed, it is recommended to provide an additional possibility of mechanical regulation, since the speed of opening the curtains may not correspond to the degree of heat heating.

Regardless of the type of fuel used, the electric generator is a source of increased noise, as well as vibrations. This fact entails a number of restrictions. Thus, the generators cannot be used in places with increased requirements for vibration and noise loads. Therefore, many owners wonder how to make noise insulation for the generator.

Noise level of power plants

The noise from the working electro-unit interferes with a relaxing atmosphere in the room. The optimal option is to transfer the power plant into a separate structure, outside the main housing. The ability to carry out such a transfer is not everywhere. In some cases, diesel and gasoline generators are mounted in separate technical premises, such as boiler rooms or shields.

The noise that produces a benzogenerator during operation can be classified by sources of origin.

• Mechanical noise, as well as noise appearing as a result of engine vibration;
• Noise appearing as a result of exhaust exhaust gases;
• Noise arising when air movement. Air is constantly circulating to the cooling system fan.

Protection methods

The global method is most suitable for enterprises where there is an opportunity to use individual buildings to install an electric generator. One option is to build a new building from special sandwich panels with high sound insulation. In view of the need for large financial investments, living conditions This option is practically not used.

You can also install the unit in a separate insulated room. Conducting a complex of finishing work using mineral wool, foam or other similar material, It is possible to increase the soundproof characteristics of this room.

In domestic conditions, preference is most often given to point methods. Their goal is to eliminate the vibrations of individual components and elements of the electric generator, which act as sources of noise. Specially designed shock absorbers can be used to reduce vibration. Many manufacturers make electrical generators based on a metal frame with vibration pouring.

Mechanical noise can be reduced by soundproofing casing. Around the electric generator, equipped with such a casing, a sound barrier is created. In addition, it is possible to operate an outdoor unit. IN this case problems may arise with maintenanceWhat is solved by using an all-weather container that protects the equipment and freedom of access to the generator.

Noise insulation of the gasoline generator includes the installation of the muffler. A qualitatively selected and installed silencer can reduce the noise level produced by the electric generator, by 49DB. Among the advantages of this method, you can note the small cost and ease of installation. It is necessary to ensure that total length Exhaust systems, including the silencer, was not more than three meters. Otherwise, the inverse pressure of exhaust and spent gases is possible.

Among additional anti-vibration measures, it is possible to note elastic connections of cables, fuel pipelines, as well as exhaust exhaust systems of exhaust gases.

For noise reduction, ventilation grids can be used. They are selected based on the generator power. Manufacturers recommend that at least 50% of the free space remain in the open form.

Among comprehensive solutionsWith which noise insulation is carried out for the generator, the Eurocozhok is allocated. Externally metal carcass, Outside sheathed sheet metal. Below - transport wheels, the size of which varies depending on the power plant, up to the automotive. In addition to noise absorption, it provides protection against harmful climatic conditionsas well as from vandals.

Nowadays, when electricity is often disconnected or it is necessary to connect light in a country house, often use backup voltage sources. But they work on internal combustion engines and, accordingly, publish some sound. Today, silent aggregates have not yet invented, as they did not come up with another alternative to these engines. Therefore, you have to admit that the installations are noisy and often quite loud, but this is not a problem at all. Each consumer can solve it in a fairly short time.

How to get rid of the noise of the generator?

If the equipment is in the garage or a shed, that is, on the street, you will agree that it will not interfere with the noise. But often people do not have such premises, and the technique has to be put in the house, basement or on the balcony. Then, you see, this annoying noise will not be easy to interfere, but also annoy.

The first thing you can do is when buying pick up the most optimal option The unit, which would make less noise or purchase additional devices, such as a noise insulating casing. Usually gasoline models work much quieter than their diesel competitors. Qualitative devices that have Japanese gasoline engines make noise in 65 dB. As for diesel units, the noise level here exceeds 70 dB.

It is worth noting that the work of the technique is equated by the level of noise to the loud conversation, a quarrel or scream. For example, a conversation in a normal tone or a noise of a surf on the seashore has a power of 40-50 dB, but the work of a vacuum cleaner is 80 dB. The volume of the jet engine and the sound at the concert in the country of the rock band is equal to 100-110 dB.

The main causes of loud equipment

Many factors affect the volume of the unit's work, but several main reasons can be distinguished, which directly cause noise.

1. The first reason is the usual vibration. To get rid of her, or at least a little to reduce the mind, you must correctly put the design. Note that the unit should stand on an absolutely smooth surface, and the rubber mat should be put under it, which will reduce the vibration and the sound, respectively. In addition, you need to push the device from the walls, furniture items. Additionally, make insulation of the exit point of the exit for exhaust with a special soft gasket.
2. The second cause of noise is the exhaust system. Usually, the technique is already equipped with an excellent silencer, but it can be replaced or improved if necessary.
3. The third factor is the cooling system. Everyone knows that air cooling makes loud sounds that can be eliminated by a protective casing with special lattices that absorb the sound. You can install equipment in a special soundproofing room or to build a casing yourself. But the company's specialists have already thought about it and now, together with the installation, you can purchase a professional modern Eurocup, which will ensure the quiet work of the aggregate.

With the help of the Eurochak, you can solve several problems at the same time, for example:

• He copes perfectly with different species Noise and extinguishes vibration.
• It is equipped with modern ventilation, which provides admission fresh air In the chamber and prevents the equipment overheating, even on the hottest days.
• The casing perfectly protects the device itself from dirt, dust and adverse weather conditions.
• It has excellent protection against vandals.

It is worth saying that a diesel generator who dismisses noise in 75-80 dB without a casing, after purchasing the product will give only 60 dB, which is equal to the conversation.

As a result, I want to say if you decide to put the design on the street or near the residential buildings, then you should think about its noise insulation, and acquire the Eurocup.

It can become an excellent option for autonomous power supply. it good decision For backup, emergency nutrition. Today we will find out more on the level of noity Generators, consider the quietest, silent benzogenerators.

Noise of gasoline generator depends on loads from. Definitely great importance Also will have the quality of the assembly. It is important that there was a good silencer, which is really able to suppress sounds.
