The maintenance of dual -speed smoke is mainly concentrated in the maintenance of the bearings and the maintenance of the impeller.
1. Leaf wheel maintenance:
(1) Eliminate the dust, oil, and rust on the surface of the impeller to reveal the metal.(2) View whether the blades have the disadvantages such as cracks. If there are cracks, etc.Use wear -resistant welded wire to replenish the wear and damage parts of the fan blades, and the wear -resistant pile welding of the blades and side plates is 5mm thick to ensure the smooth transition of the pile welding. Part of it can be welded to 8mm thick.Board stripes.(3) The welding process of the fan of the fan should be welded in segmented, and the thermal input should be controlled as much as possible, and the release of the blade is reduced.
1. The maintenance of the bearings:
(1) Turn on the dual -speed fire smoke exhaust aircraft every month to run in so that the bearing of the smoke exhaust wind machine is smooth and adheres to the good situation.(2) In general, it is injected once a year. If the bearing is absent, the reason should be checked to make up for it at any time.(3) Check whether the screws of each component of the dual -speed fire smoke exhaust fan are loose and whether there is a missing part. If there is loosening, the missing parts should be repaired in time.(4) When the two -speed fire smoke exhaust fan operates, listen to whether the sound announced by its homework is normal.
