Treatment of unstable wind of centrifugal fans

Centrifugal fans sometimes have the problem of unstable wind force. Once such a problem occurs, its actual operation and application will be greatly affected. We should first understand the reasons for its unstable wind force, so that the problem can be solved correctly.

1. Because there are some problems in the diodes of the four rectifiers of the centrifugal fan, the performance of the equipment is compromised.

2. The carbon powder of the motor rotor and commutator is different from the motor carbon brush itself. At this time, you can discuss the adjustable resistance of the centrifugal fan first, and it is good if the resistance value changes with the adjustment.

3. The problem may be in the thyristor, as if the lead, looseness, short-circuit failure, and inability to touch are all problems that cause the speed of the centrifugal fan to be unstable. In addition, if the adjustable resistor is loose, the stability of the rate will also be affected.
