Roots Blower Is there a positive and negative rotation?

Case question: A customer called to inquire, there is too much dust in the inlet silencer of Roots blower, and they want to remove the dust inside. Don't you know if it can be reversed?

Answer: If there is too much dust, the fan cannot be reversed. That will cause the motor to burn off and damage the machine body.

I don't know what system your fan is used for. Fans for general purposes can be cleaned with cleaning agent (diesel, gasoline, rust remover, etc.). If there is too much dust, I suggest you find a professional technician to disassemble all fans for maintenance. Under what circumstances can Roots blower be reversed?

Whether Roots blower has positive and negative rotation

Generally, the roots blower cannot be reversed when it is powered on. If the roots blower reverses under normal operation, the motor will burn out instantly and the impeller will be broken, causing irreparable losses. The reason for this is usually that the check valve (also called check valve) is not installed

However, when the Roots blower stops, it can be reversed. If you plan to reverse for a long time, you should communicate with the Roots blower manufacturer in advance and adjust the front and rear end clearance. If the Roots blower reverses due to forward rotation inertia and backpressure at the outlet due to sudden power failure of the Roots blower, the coupling may be damaged, or even the rotor and even the blower body may be damaged.

Summary: Operating principle of Roots blower

Roots blower operates in accordance with the principle of "no-load startup, load shedding and shutdown". During normal operation of Roots blower, sudden reversal is not allowed. Reversal of two blade blower will lead to rotor damage immediately. The gear of the three blade fan may also be damaged. The solution is to correctly install the check valve and check whether the check valve can be closed.
