Centrifugal fans may sometimes encounter some problems during operation. These problems are usually caused by improper manufacturing, selection, installation, and operational management. However, some issues are not easily discernible. So how to determine if the centrifugal fan is operating normally?

1. Whether the bearing seat feels gentle, not numb or hot to the touch;

2. Whether there is vibration or large-scale shaking during the operation of the impeller;

3. Check for any abnormal sounds during the operation of the impeller;

4. Check if there is any jumping in the transmission triangle tape;

5. Check for any abnormal fluctuations in the ammeter pointer during impeller operation.

Based on the above phenomenon, it can be determined whether there is a problem with the centrifugal fan. Then make specific analysis and handling of the more specific problem.
