What are the problems of Roots blower that need overhaul?

Belt, lubricating oil addition, filter cotton replacement, etc., but some problems may require us to return to the factory for overhaul. What problems need to be returned to the factory for overhaul?

1. Excessive impeller gap

The clearance between the impellers of Roots blower is determined by certain standards
During use, the clearance between impellers becomes larger, which will affect the normal operation of Roots blower. For some small Roots blowers, such as some three leaf Roots blowers, we have considerable expertise, and we can repair them by ourselves. However, for some large Roots blowers, such as two blade large Roots blowers, if there is a problem with the impeller clearance of such blowers, they need to be returned to the factory for overhaul. The reason is that such Roots blowers have large impellers and need special mechanical equipment for treatment.

2. The bearing is bent and broken

Bearing is an important part connecting the impeller and the motor. The quality of the impeller produced by some manufacturers is unqualified, or the factory does not test, and the bearing has serious balance errors. Then, under the long-term operation of Roots blower, bearing deformation is easy to occur, and serious conditions may lead to the fracture of the Roots blower shaft and the burning of the motor.

In this case, we need to return the mechanical equipment to the factory again for adjustment, relevant tests and installation.

3. Problems of Roots blower motor

If there is a problem with our motor, we need to disassemble the motor and send it back to the original factory for maintenance. The motor is vulnerable to damage under unreasonable working conditions. In addition, the damage of the motor is generally difficult to recover. It is difficult to ensure the service life of the motor without returning it to the original factory for maintenance.

Summary: The overhaul problem of Roots blower generally exists inside Roots blower, and
