How To Repair And Clean The Centrifugal Fan
In the centrifugal fan, the impeller, as an important part, directly affects the efficiency of the centrifugal fan. Its geometry, size, number of blades and manufacturing accuracy have a great influence on performance. The impeller can be calibrated by static or dynamic balance to ensure smooth rotation of the fan. According to the different direction of the blade outlet, the impeller is divided into three types: forward, radial and backward. The top of the blade of the forward impeller is inclined to the direction of rotation of the impeller; the top of the blade of the radial impeller is radial, divided into straight blade and curved blades; the top of the blade of the backward impeller is inclined in the opposite direction of the rotation of the impeller.
