What causes the overcurrent of Roots blower?

It is believed that during the use of Roots blower by major manufacturers, the current is often too high and the motor is overloaded. What are the reasons? Now let's have a detailed understanding!

First, it may be the problem of pipe blockage. The air outlet of the fan is not smooth, and the air cannot be discharged, so the pressure rises. At the same time, the motor causes overpressure and overload, which causes the rise of Roots blower ammeter; It may also be due to lubricating oil.

If the lubricating oil of Roots blower is insufficient and the blower continues to operate under the condition of oil shortage, the impeller failure friction and gear wear will increase, thus increasing the motor load, which will only increase the motor burden and accelerate the loss.

Misoperation is also one of the possible reasons. Current overload may also be caused by problems during operation, such as reverse operation when installing the check valve and operation before all the gate valves are opened. Such operations are likely to cause instantaneous burning of the motor. Operation should be carried out according to regulations, and carelessness should not cause unnecessary trouble. Another problem is the fan itself. Roots blower has its own quality problem. When installing the fan, many parts and components do not fit well in the gap, which will cause additional friction. In addition, some parts and components may be damaged, increasing the motor load, and causing the fuse to blow.

The Roots blower of our company will not have such quality problems.
