ZEGA screw air compressor will make large or small noises during operation, where do these noises come from and how to deal with them? Today, our professionals of Hunan Ruisheng Electromechanical Equipment Co., Ltd. analyze as follows:

Noise origin:

　　Air compressors play an important role in production, but air compressors are a kind of equipment with strong noise. The primary origin of air compressor noise is the four parts of the air intake, exhaust port, mechanical port and electromagnetic port. The air compressor has a high noise level, low frequency se, long transmission distance, and large pollution range. In particular, the frequency of some noises is close to the natural frequency of human internal organs, causing resonance, causing dizziness, nausea, tachycardia, hypertension and other diseases, which not only causes people's work and quality of life to fall, but also simply attacks safety accidents and interpersonal conflicts. Therefore, controlling air compressor noise is not only an important issue for labor maintenance and environmental maintenance, but also an important issue for production enterprises to continue to be healthy, so landing air compressor noise and noise management are particularly important.

　　Disposal plan:

　　1. How to lower the noise of the air compressor inlet: the method of installing a muffler can be used generally. Since the noise of the air compressor inlet is a low-frequency characteristic, it is advisable to choose a resistant muffler.

　　2. How to lower the exhaust port noise of the air compressor: The air compressor with high exhaust pressure and large flow rate has a high exhaust noise, and a special muffler is set up to stop the operation in the exhaust system requirements. The exhaust port muffler requires a large amount of muffling, a wide muffling frequency band, and has the effect of reducing pressure expansion and reducing the pressure drop of exhaust venting to reduce the exhaust venting noise.

　　3. How to land the noise of the air compressor body: control the body noise of the air compressor, motor noise, commonly think about the use of sound insulation and sound absorption control technology. The method is to add a sound insulation cover or sound insulation room to the tightening machine to block the transmission of noise.

　　4. How to land the oscillation noise of the air compressor body: to control the noise of the air compressor, you need to control the oscillation, the oscillation of the air compressor is first transmitted outward through the foundation and pipeline system, and the control of the oscillation is first controlled by vibration isolation.
