Precautions For Wear Of Boiler Fan
May 27, 2017

The abrasion of the driving part of the boiler induced draft fan is a common equipment problem, including the bearing position of the exhaust fan, bearing room wear, fan shaft bearing wear, etc., in view of the above-mentioned fault 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 heat can not be completely eliminated, easy to cause material damage.

Life common sense tells us no matter what mechanical equipment, in the use of a period of time will appear big and small problems, centrifugal fan is no exception to the components appear curved or broken; and brush plating by the thickness of the coating, 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, in the overall effect of the force, will still cause the rubber drum wear again.
