How to control the noise of high-pressure fans?

　　How to control the noise of fan products?

　　Noise comes from the vibration of objects, and fan noise mainly consists of three parts:

　　1. Solid vibration radiation noise generated by general vibration of fan rotation, electromagnetic noise during motor operation;

　　2. The aerodynamic noise radiated from the air inlet and outlet (* * * the main source of noise), as well as the dynamic noise generated by air flow;

　　Among them, aerodynamic noise mainly includes rotational noise and eddy current noise.

　　3. Solid vibration noise generated by the casing, motor, and bearings on the fan, as well as mechanical noise during fan operation.

　　The fan noise is mainly composed of 2 and 3. Dynamic noise is caused by fluid eddies or sudden pressure changes, while mechanical noise is caused by mechanical vibrations. The aerodynamic noise in high-pressure fans is greater than that in medium and low-pressure fans.

　　How to control the noise of fan products?

　　1. Add isolation cover

　　2. Install the muffler.

　　3. Wrap it with a flexible hose.

　　4. Sound insulation measures are taken during the initial installation of the fan.

　　5. Install the fan and adopt vibration isolation measures.
