Centrifugal fan blower backward inclined centrifugal fan transmission part belt pulley made of steel

Fault maintenance:

The wear of the transmission part of centrifugal fan is a common equipment problem, including the wear of the bearing position of the suction fan, the wear of the bearing chamber, and the wear of the bearing position of the blower shaft. In view of the above faults of centrifugal fans, the traditional maintenance methods include surfacing, thermal spraying, brushing, etc., but they all have certain drawbacks: the thermal stress caused by high temperature of repair welding cannot be completely eliminated, which is easy to cause material damage and lead to bending or breakage of parts. However, brush plating is limited by the thickness of the coating, which is easy to peel off, and the above two methods are to repair the metal with metal, which cannot be changed.

Contemporary western countries mostly adopt the repair method of polymer composite materials to solve the above problems, and the American Fuslan technology system is more widely used, which has super adhesion, excellent compressive strength and other comprehensive properties, and can be disassembled and machining free. There is neither the influence of thermal stress of repair welding, and the repair thickness is not limited. At the same time, the metal material of the product does not have the retreat property, which can absorb the shock and vibration of the equipment and avoid the possibility of wear again. It is also gradually replacing the traditional method in the application of fault repair of centrifugal fans in China.
