Centrifugal fan fault maintenance

- Feb 17, 2020-

The abrasion of the driving part of centrifugal fan is a common equipment problem, including the abrasion of the bearing position of the exhaust fan, the bearing chamber, and the bearing position of the blower shaft. In view of the above faults of centrifugal fan, the traditional maintenance methods include overlay welding, thermal spraying, brush ferry, etc., but all of them have some disadvantages: the thermal stress caused by high temperature of repair welding can not be completely eliminated, which is easy to cause material damage, leading to bending or fracture of parts; while brush plating is limited by the coating thickness, which is easy to peel off, and the above two methods are metal repair metal, which can not change the "hard" Under the combined action of various forces, the "hard" matching relationship will still cause the rubber coated drum to wear again. The current western countries mostly adopt the repair method of polymer composite materials to solve the above problems, while the American fusible blue technology system is widely used. It has super adhesion, excellent compressive strength and other comprehensive properties, and it is free of disassembly and machining. At the same time, the metal material of the product does not have the concession, which can absorb the shock vibration of the equipment and avoid the possibility of re abrasion. In the domestic application of the centrifugal fan fault repair, it also gradually replaces the traditional method.https://www.ck-stone.com/
