How to solve the problem of loud air compressor noise?

 

As a kind of aerodynamic equipment, air compressor is a noisy equipment. Air compressors are widely used in industrial fields. Therefore, if the noise of the air compressor is too loud, it will cause symptoms such as dizziness, nausea, tachycardia, high blood pressure, etc. among workers. Therefore, it is very necessary to reduce the noise of the air compressor.

 

1. Air inlet and outlet

 

Check the equipment structure of the air compressor inlet and outlet, such as whether the fan blades are damaged or have slight collision and friction with the fan cover, which will cause noise. For the friction noise of the equipment, the lubricating oil can be added or replaced to reduce the friction noise of the equipment. For aerodynamic noise at the air inlet and outlet, a muffler can be installed, and porous sound-absorbing materials are used to fix it on the inner wall of the air flow channel. The resistive muffler has a good silencing effect on medium and high-frequency noise.

2. Air compressor body

 

In view of the vibration noise of the entire air compressor, it is recommended to install a shock-absorbing base, which can slow down the vibration and reduce the noise to a certain extent. Air compressors often emit strong vibration noise. At this time, it is necessary to adopt vibration damping treatment on the base of the air compressor. According to the different vibration frequencies of different air compressors, as well as the weight and model of the machine, appropriate dampers are selected. vibration products. Both shock absorbers and spring shock absorbers can effectively reduce vibration noise. To comprehensively control the noise of the air compressor, a sound insulation cover can be installed, and the interior is filled with vibration-absorbing materials to prevent the transmission of vibration and sound waves.

 

3. Structural design

The noise in the air compressor pipeline is also very serious, so it is necessary to adopt a vibration-absorbing design for the pipeline. Generally, a throttling orifice plate can be installed in the exhaust pipe to slow down the vibration.

 

4. Gas storage tank

Another source of air compressor noise is the noise in the gas storage tank. We can hang a sound absorber inside the tank and use the sound absorption effect of the sound absorber to prevent the propagation of sound waves.
