Operation check of axial flow fan

- Jul 11, 2018 -

When the axial fan is running, it mainly monitors the motor's electricity.flow, current is not only a marker of fan load, but also a forecast of some abnormal changes. In addition, always check whether the vibration of the motor and the fan is normal and whether there is friction or abnormal noise. For fans operating in parallel, care should be taken to check that the fans are operating in a surge condition.

In normal operation, the following conditions should be detected:

1. The axial fan produces strong vibration or rubbing sound;

2. The motor current suddenly rises and exceeds the rated current of the motor;

3. The motor bearing temperature rises sharply.
