Do you know what causes magnetic levitation fan surge?

1. When two fans run at the same time, the opening deviation of the guide blades is too large, causing the fan with a small opening to fall into the surge zone.

2. Serious ash accumulation in the smoke duct may cause blockage or the baffle of the smoke duct is not open enough, resulting in excessive resistance of the system.

3. Long-term operation under low load.

Methods to deal with surge generated by magnetic levitation fan:

Adjust the load of the fan, adjust the opening of the guide blades of the two fans so that the output of the fan is similar, observe and record the air pressure of the air inlet and outlet, find the cause of the fan surge, and then make corresponding treatment
