Screw air compressors produce varying levels of noise during operation. Where does this noise come from and how should it be handled? Let's analyze it for everyone below:
Air compressors play an important role in industrial production, but they are a type of noisy equipment. The primary sources of noise from air compressors are the intake, exhaust, mechanical, and electromagnetic ports. The noise level of the air compressor is high, the transmission distance is long, and the pollution range is large. Especially when the frequency of certain noises is close to the natural frequency of human internal organs, resonance can occur, causing dizziness, nausea, tachycardia, high blood pressure and other illnesses. This not only leads to a decrease in people's work and daily quality, but also causes simple safety accidents and interpersonal conflicts. Therefore, controlling the noise of air compressors is not only an important issue for labor and environmental maintenance, but also an important issue for production enterprises to continue healthy development. Therefore, reducing the noise of air compressors and noise management is particularly important.
So how to reduce noise?
1. How to reduce the noise at the inlet of the air compressor: Generally, the method of installing a muffler can be used. Due to the low-frequency nature of the noise at the air compressor inlet, it is advisable to use a resistant muffler.
2. How to reduce the exhaust noise of an air compressor: For air compressors with high exhaust pressure and high flow rate, a dedicated muffler should be installed in the exhaust system to stop the operation due to the high exhaust noise. The exhaust muffler requires a large amount of noise reduction, a wide frequency band for noise reduction, and has the effect of reducing pressure and expanding capacity, reducing the pressure drop of exhaust venting, in order to reduce exhaust venting noise.
3. How to reduce the noise of the air compressor body: Control the body noise and motor noise of the air compressor by using sound insulation and absorption control techniques. The method is to install soundproof enclosures or soundproof rooms on the compactor to obstruct the transmission of noise.
4. How to reduce the oscillation noise of the air compressor body: To control the noise of the air compressor, it is necessary to control the oscillation. The oscillation of the air compressor is mainly transmitted outward through the foundation and pipeline system, and the control of the oscillation is mainly achieved through vibration isolation control.
