Why does the screw air compressor make noise when it is running?

Air compressors play an important role in industrial production, but air compressors are noisy equipment. The source of the noise of the air compressor is the four parts of the air inlet, exhaust port, mechanical port and electromagnetic port. Air compressors have high noise levels, long transmission distances, and large pollution areas. Controlling the noise of air compressors is not only an important issue of labor protection and environmental protection, but also an important issue for the sustainable and healthy development of production enterprises. Therefore, it is particularly important to reduce the noise of air compressors and noise management. So how to reduce noise?

1. How to reduce the noise of the air compressor inlet:

Generally, the method of installing a muffler can be used. Since the noise at the air compressor inlet is low-frequency, it is advisable to use a resistant muffler.

2. How to reduce the noise of air compressor exhaust port:

The air compressor with high exhaust pressure and large flow rate needs to install a muffler in the exhaust system to control it due to the high exhaust noise generated. The exhaust muffler requires a large amount of noise reduction, a wide noise reduction frequency band, and has the effect of decompression and expansion, reducing the pressure drop of the exhaust air, so as to reduce the noise of the exhaust air.

3. How to reduce the noise of the air compressor body:

To control the body noise and motor noise of the air compressor, the control technology of sound insulation and sound absorption is adopted. The method is to add a sound insulation cover or a sound insulation room to the compressor to prevent the transmission of noise.

4. How to reduce the vibration noise of the air compressor body:

Control the noise of the air compressor to control the vibration. The vibration of the air compressor is transmitted outward through the foundation and the pipeline system. The vibration control is controlled by vibration isolation.
