Roots Blower After a certain number of years of use, failure may occur due to the impossibility of maintenance. For some large Roots blowers, the maintenance cost is also expensive. Some Roots blowers have been used for many years
With the technical improvement and upgrading of Roots blower, it is difficult to purchase and replace the old Roots blower parts. Therefore, in order to solve the customer's concerns in this regard, we summarized the conditions under which the Roots blower needs major repair
Avoid the situation that too many faults can not be repaired.

1. The clearance between the impellers of Roots blower is subject to certain standards. If the clearance between impellers becomes larger during the use of Roots blower, the normal operation of Roots blower will be affected. For some small Luo
We have considerable professional knowledge of the Roots blowers, like some three leaf Roots blowers, and we can repair them by ourselves. However, for some large Roots blowers, such as two blade large Roots blowers, such fan impeller clearance appears
If there is a problem, it needs to be returned to the factory for overhaul. The reason is that this type of Roots blower has a large impeller and needs special mechanical equipment to deal with it.

2. The bearing is bent and broken

Bearing is an important part connecting impeller and motor. Some Roots blower manufacturers produce unqualified impellers, or do not test the bearings when they leave the factory, and there are serious balance errors in the bearings. Therefore, Roots blower will operate for a long time
Under operation, bearing deformation is very easy to occur, and serious conditions may lead to the fracture of Roots blower shaft and the burning of motor.

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

3、 Roots Blower Motor problems

If there is a problem with our motor, we need to disassemble the motor and send it back to the original factory for maintenance. Under unreasonable working conditions, the motor is very easy to be damaged. In addition, the damage of the motor is generally difficult to recover and will not be returned
It is difficult to guarantee the service life of the motor when it is returned to the original factory for maintenance.
