How to Reduce the Noise of Industrial Fans and Blowers by Xianrun Blower?


(1) Centrifugal fan impeller, fan shaft, pulley and coupling, these rotating parts must be processed with the dynamic balance and static balance correction, and assemble after qualification.  At the same time, the interval between motor cooling fan blade and fan shroud should be reasonable, so as to reduce the the motor cooling fan blade rotation noise.

(2) Check the centrifugal fan connecting bolts and anchor bolts looseness regularly, and abnormal wear or bad lubrication bearing, whether the belt is tension, etc. For any abnormal situation, should stop the centrifugal fan immediately and check carefully.

(3) During the installation, between the centrifugal fan and the reinforced concrete foundation should have soft materials, such as cushion rubber, cork board or felt board and so on, in order to reducing or eliminating vibration of centrifugal fan passing to reinforced concrete foundation for maximum limit.

(4) It is better to install flexible connection in the industrial centrifugal fan air inlet and air outlet, so as to reducing or eliminating vibration of centrifugal fan passing to air duct in rubber hose for maximum limit.

(5) Choose a reasonable motor cooling fan blade shape,parameters, and etc., and reduce the vortex noise of motor cooling fan effectively.
