The influence of improper operation of centrifugal fan

1. centrifugal fan overspeed or overloading operation;

2. bad lubrication, or have scaling, damage and other phenomena;

3. the line point is close to the critical point, or falls into the critical speed region;

4. the actual value of the process parameters is deviated from the design value, such as temperature, flow rate, pressure and load, so that the fan can not operate normally.
