with regards toRoots FansTo meet what problems need to be overhauled? On this issue Roots fan small editor to take you to understand.
1、Impeller gap is too big problem
The clearance between the impeller and the impeller of the Roots fan is by a certain standard. For some small Roots fans, like some three-blade Roots fans, we have considerable expertise, we can carry out self-repair. But for some large Roots fan, such as two-leaf large Roots fan, such a fan impeller clearance problems, you need to return to the factory for overhaul, the reason is that the impeller of this type of Roots fan is more massive, and requires specialized machinery and equipment to deal with.
2、Bearings are bent and broken
Bearing is an important part of the link impeller and motor, some manufacturers produce impeller quality is not qualified, or factory does not test, bearing there is a more serious balance error, then, under the long-term operation of the Roots fan, it is easy to bearings deformation, a serious situation may lead to the Roots fan shaft fracture and the motor burned out.
In this case, we need to return the machinery and equipment back to the factory, make adjustments and do the relevant tests before carrying out the installation work.
3、Roots fan motor problems
If we have problems with the motor, we need to disassemble the motor and send it back to the original factory for overhaul, the motor is very easy to cause damage in an unreasonable working environment, and the damage to the motor is generally very difficult to recover from, and it is very difficult to be able to ensure that the life of the motor without returning to the original factory for repair.
