The cause of the tripping of the cabinet centrifugal fan


In the actual cabinet centrifugal fan operation, the centrifugal fan trips due to various environmental and other factors are mainly caused by the following reasons:

1. The dust collector pipe is relatively short, and the valve is closed (actually a butterfly valve, which is not dead), but the resulting system resistance is insufficient to cause the centrifugal fan motor to trip;

2. Because the pipeline is too long, the valve is not closed, but the resistance is still higher than the resistance that the fan can withstand, so it trips;

3, the cause of the electrical appliance caused the fan to trip;

4. The mechanical cause causes the fan to trip;

5. Failure to fully open the fan damper will cause a trip;

6. The cross section of the duct at the fan outlet is too large, causing the shaft power required by the fan to be too high, the motor load is overloaded, and the current exceeds the rated value;

7. The reason for the small resistance of the dust collector and pipeline.
