Centrifugal fans transmission parts wear is often seen equipment problems, including blower bearing position, bearing chamber wear, 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, easy to cause material damage to farming fans wholesale, resulting in part appears bent or fracture; and electric brush by coating thickness restrictions, easy to peel off the fan culture, and the above two methods are used to repair metal breeding metal fan, you can not change the "hard on hard" relationship with the fan culture Which, in all Under the combined effect of the force, will continue to cause the drum again wear plastic bag. The main consequence of this reflux export performance generated as follows: First, the exit area can not be fully utilized, the actual amount of wind often can not meet the design requirements. Second, the destruction of the uniformity of air, affecting the heat transfer performance of the evaporator. Third, the return air collision speed of rotation of the impeller, resulting in aerodynamic noise. Thus, this phenomenon should be avoided. Which is good farming fans, Changle farming fans, the people of China Qingzhou Qingzhou temperature control equipment supplied by Chinese citizens thermostat plant.
