Operational Inspection of Axial Fans

When the axial fan is running, it mainly monitors the current of the motor. The current is not only a marker of the fan load, but also a forecast of some abnormal changes. In addition, it is necessary to frequently check whether the vibration of the motor and the fan is normal and whether there is friction or abnormal noise. For fans running in parallel, check whether the fans are running in a surge state. In normal operation, it should be stopped immediately if it encounters the following conditions:

1. The axial flow fan produces strong vibration or scratching sound;
2. The motor current suddenly rises and exceeds the rated current of the motor;
3. The temperature of the motor bearing rises sharply.
