How to reduce noise when the screw air compressor is running too noisy

Screw air compressor in the process of gas production, noise is very headache, if the air compressor and the production department distance is relatively close, a long time will affect our hearing, we will generally install the air compressor in the corner of the factory, far away from the production and processing personnel, but some small enterprises site problems can not guarantee the distance, at this time we must find ways to reduce the noise of the machine.

Granklin water lubricated air compressor noise between 57-80 dB, the greater the power of the machine, the noise will increase accordingly.

screw air compressor mainly has two parts: pneumatic noise and mechanical noise. Aerodynamic noise is caused by periodic intake and exhaust noise, eddy current noise and rotating noise. Mechanical noise is caused by gear noise, pipeline vibration and fan noise.

Measures to control and reduce noise are:

1. improving the structure and processing technology, controlling the noise source, correctly selecting the rotor profile, improving the flow state of the airflow in the cylinder, reducing the eddy current loss, selecting a reasonable speed, improving the dynamic balance of the rotor, equipped with low-noise gears and improving the design and manufacture of cooling fans.

Acoustic enclosure and sound absorption screen are 2. provided. Box-shaped full-cover low-noise fast installation can reduce noise by 20 ~ 30dB(A).

3. room for sound insulation and sound absorption treatment.

4. set the muffler. In the intake and exhaust ports are respectively set up intake and exhaust muffler, can reduce the noise of about 25dB(A).
