What should I do if the cabinet centrifugal fan trips?
Solution:
1. Reduce the opening degree of the fan outlet damper.
2. Reduce the shaft power.
3. If the damper is adjusted and the system requirements cannot be met, it is necessary to consider replacing the fan.
4. Under normal circumstances, the start of the fan is to close the damper, that is to say, when the damper is closed, the fan will not load (generally there are few).
5. Replace the centrifugal fan motor.
6. If it is a multi-wing fan-shaped damper (the damper is rotated to the left and right), the damper is not rotated correctly, and the damper is opened at a lower current.
7. Check the concentricity (D type), the bearing, and whether there is excessive dust in the impeller.
