Fault maintenance of centrifugal fan
- Oct 31, 2017-
The abrasion of the driving part of the centrifugal fan is a common equipment problem, which includes the bearing position of the fan, the wear of the bearing chamber and the wear of the blower shaft bearing position. For the malfunction of centrifugal fan, traditional maintenance methods have surfacing, thermal spraying, brush crossing, etc., but there are some drawbacks: the thermal stress produced by the welding high-temperature can not be completely eliminated, easy to cause material damage, resulting in parts bending or fracture, and brush plating is limited by coating thickness, centrifugal fan is easy to peel off, And the above two methods are metal repair metal, can not change the "hard to hard" coordination relationship, under the combined action of various forces, will still cause the rubber drum wear again. Contemporary Western countries to solve the above problems with the use of polymer composite repair methods, and more applications are the United States, the Blue technology system, its strong adhesion, excellent compressive strength, such as comprehensive performance, can be removed from machine-free processing. Not only does not have the effect of welding thermal stress, repair thickness is not limited, at the same time products have not had the concessions of metal materials, can absorb the shock vibration of equipment, to avoid the possibility of wear again, in the domestic application of centrifugal fan fault repair has gradually replaced the traditional method.
