Centrifugal fans transmission parts wear is often seen farming equipment problems FRP fans, including the blower bearings bit worn bearing chamber, blower shaft bearings bit wear. Centrifugal fan for the failure of traditional repair methods are welding, thermal spraying, brush crossing, etc., but have certain drawbacks: high temperature welding thermal stress generated can not be completely eliminated, could easily lead to material damage, resulting in part appears bent or broken; The electric brush by coating thickness limit livestock breeding fan, easy peeling, and the above two methods are used to repair metal metal, can not change the "hard on hard" relationship with farming fan, fan culture under the combined effect of the various forces will still cause the drum again wear plastic bag. Valve adjustment (export / import / snail line) exit valve adjustment is change the characteristics of the pipe network, rather than changing the characteristics of air-conditioning fan. Air volume control range is usually at the bottom of the fan performance curves of all the rated conditions. Because the employer in order to increase the resistance of the pipe network method to change the properties of the pipe network, the additional consumption drop off a small damper resistance generated when regulating the economy is bad.
