How to silence the air compressor 30

The propagation of sound can only be solved by controlling the propagation of the air, because it is a house, so you still check the anti-noise sponge of the air compressor shell, the sound is vibration, the sponge can solve this problem very well, if it is further improved, the machine needs to be sealed but it needs to be ventilated from the outside world, the specific method is to isolate the machine with a silencing board.

In fact, this method is very basic, no matter what kind of compressor you need.

For noise, there are usually two ways we use: one is noise isolation, and the other is noise reduction, which should be solved according to the situation; What style of air compressor do you use? Is it piston, screw or sliding? In this case in the laboratory, it is best to choose the scroll type, which has very low noise.

First, the walls are covered with sound-absorbing panels, the ceiling is dropped with gypsum sound-absorbing panels, and the outside of the door is covered with a thick curtain. Check whether there is a sound-absorbing sponge in the air compressor case. Also, pay attention to the negative effects of high temperatures.

Silencer filter with air compressor.

1. Establish a sound insulation cover

After installing a muffler or setting up a muffler at the inlet and exhaust ports of the air compressor, the airflow noise can be reduced to less than 80db(a), but the mechanical noise and motor noise of the air compressor are still very high, so a sound insulation cover should also be installed on the air compressor unit. If you choose the right air filter that is suitable for the air compressor, the noise will be relatively reduced.

2. Set up a silencing tunnel

The underground or semi-underground tunnel of the anechoic tunnel, the tunnel wall is made of bricks with good sound absorption. Connect the air intake pipe of the air compressor with the anechoic tunnel, so that the air enters the air compressor through the anechoic tunnel. The use of muffler pit can greatly reduce the intake noise of the air compressor, and the service life is longer than that of the general muffler.

3. Suspension space sound absorber:

It is to disperse and hang sound absorbers on the roof of the plant to absorb noise to achieve the purpose of reducing the working noise of the air compressor.

4. Install the muffler

The main noise sources are the intake and exhaust ports, and appropriate intake and exhaust mufflers should be selected. The spectrum of air compressor intake noise is low-frequency, and the intake muffler should be selected as a resistant structure or an impedance composite structure based on individual and resistance. The exhaust air pressure of the air compressor is large and the air velocity is high, so a small hole muffler should be used at the exhaust port of the air compressor.

Of course, the most important point is to choose the right air compressor accessories.

This is a big business opportunity. Whoever solves it will send it.

The operating noise of the air conditioning compressor cannot be eliminated, and the noise can only be appropriately reduced by some means.

For example, you can use soundproof cotton for the compressor to eliminate part of the noise, you can appropriately adjust the strength of the fixed foot of the compressor to reduce the operating noise, and reduce the operating noise by adjusting the operating state of the air conditioning and refrigeration system.

Targeted improvement measures need to be taken on a case-by-case basis.

The choice of noise reduction method of compressor depends on the specific situation of the compressor, and the sound insulation cover is generally used to deal with it, because the sound insulation cover can carry more noise reduction methods and can better adapt to the various noise situations of the compressor. Specific noise reduction equipment includes acoustic covers, soundproof doors and windows, ventilation mufflers, cooling fans, etc.

Air compressor noise control measures.

Generally, three methods of sound absorption, sound insulation and sound reduction are adopted, and when the air compressor room is surrounded by vibration-sensitive buildings, vibration control means are also required.

1. To control the air intake noise of the air compressor, the method of installing a muffler or other muffler is generally adopted. If a muffler is used, it is advisable to choose a resistant muffler with a wide range of low frequency and low and medium frequency muffler performance.

2. The exhaust noise generated by the air compressor with high exhaust pressure or large flow rate is high, and a special muffler should be set up to control it.

3. To control the body noise and motor noise of the air compressor, the measures of sound insulation and sound absorption are often adopted.

It is not possible for the compressor to be completely silenced, and the ways to reduce the sound of the compressor are:

1. The foot bolts of the air-conditioning compressor are loose; Tighten with a wrench.

2. The base of the air conditioner compressor uses a spring vibration absorbing structure, and the product often tightens the base nut when leaving the factory to make the vibration isolation spring pressure to the minimum; Before installing the air conditioner, the chassis should be pulled out and the nut should be relaxed, so that the spring can play a vibration-absorbing role during the operation of the compressor.

3. The compressor may cause resonance of other accessories, and the accessories attached to the compressor add rubber sleeves to reduce vibration.

If it is caused by vibration, then you can: if the compressor is four legs, choose the least stressed foot to remove the shock pad. If the pipe resonates, put a movable styrofoam ring on the pipe, and add some heavy objects to the circle, such as winding some thick wires.

It takes some time to debug and it works well.

Anchor shock absorption, compressor high and low pressure interface with software connection, if it is a household machine, you can use thermal insulation and noise reduction cotton to wrap the compressor.

The use effect of the compressor exhaust silencer of Lianyungang Huabo Machinery Equipment **** 1, the air compressor silencer.

In order to suppress the noise of high-pressure steam flow, this type of exhaust steam muffler muffler is designed by integrating the most reasonable sound reduction principle. The high-pressure steam enters the depressurized body after a flow control in the muffler, and after the large volume expands the pressure, so as to form a low-pressure steam and then ejects out, in this process, the internal energy of the steam flow is partially converted into the sound energy of a certain frequency, although the noise is greatly weakened, but often due to various reasons such as the exhaust steam deviation from the design value, the noise is still higher than the standard value.

2. Air compressor muffler.

For the safety door of the boiler and other devices, its exhaust steam should avoid excessive dry sound, but also should let the steam flow flow discharge smoothly, for this reason, the silencer means of multi-stage throttling and small hole injection that are common in the past should not be adopted, this restriction has always been the design difficulty of the safety door silencer, and also the reason for the poor silencing effect of the safety door silencer. The silencer of the utility model safety door also adopts the silencing principle of anti-spray, resistance, wherein the flow control hole of smaller diameter is replaced by large hole expansion, and the anti-spray, anti-noise effect is strengthened more in the structure, and the sound suppression effect has been achieved.
