Driving Methods of Centrifugal Fan
|centrifugal fan driving methods|
Fan impeller installed on the motor shaft directly. We always called A method driving.
The centrifugal fan works through the belt and pulley driving. This method can be divided into B, C, E method.
(1) B Method
Belt pulley is in the middle of two bearings, and impeller is cantilever installation.
(2) C Method
Belt pulley is installed cantileveredly at one end of bearing, while fan impeller is installed cantileveredly at another end of bearing.
(3) E Method
Belt pulley is installed cantileveredly, while fan impeller is installed in the middle of two bearing.
The centrifugal fan works though the coupling drive.
(1) D Method
The motor connects with one end of coupling shaft, fan impeller connects with another end of coupling shaft. Motor drive bearing, bearing drive coupling shaft, coupling shaft drive fan impeller.
(2) F Method
Centrifugal fan has bearing on both sides.
