2021-07-06
Summary
It is easy to have various problems when the roots blower that has been stagnant for a long time is restarted. The common problem is the situation of locking and not moving. Today, Shandong Sanniu Machinery Group Co., Ltd. will explain to you the reason why the roots blower cannot move according to its own knowledge.

Today, Shandong Sanniu Machinery Group Co., Ltd. will explain to you the reason why the roots blower cannot move according to its own knowledge.
1. Impeller is damaged
The impeller is damaged and the fan is stuck and cannot rotate. We can easily understand this kind of failure. The impeller and the impeller bite each other, causing the impeller to not rotate. This kind of failure requires disassembly and inspection of the casing.
2. Gear damage
The normal gear bite area is about 2/3, and if it is larger than this bite area, the bite force between the gears is too large, resulting in the gear being unable to rotate, thus causing the fan to rotate.
3. Bearing damage
There are 4 bearings on the roots blower. If the bearing is damaged, it will cause the gap between the impeller and the impeller to change, and the impeller friction will occur, resulting in the fan not rotating. This is an indirect cause of the impeller gap change and a common cause of the impeller not rotating.
4, rust stuck
Roots blower idle for a long time, will appear in the internal and external rust phenomenon, rust how to appear a large area of the fall off, the impeller may appear between the stuck situation. In this case, it is necessary to clean up the rust and adjust the gap.
5. Shell deformation
It is rare that the three-leaf Roots blower cannot rotate due to the deformation of the casing. A few manufacturers produce unqualified casings. Roots blower with the same model and low price is likely to have a thin casing. If the casing is thin, the casing may deform. The deformation of the casing will naturally cause the impeller to jam. There is also a certain standard gap between the casing and the impeller.
6. Motor damage
Idle for a long time Roots blower, if there is a motor failure, will naturally produce the situation of rotation, and the motor failure is easy to judge, the motor can not rotate, the fan will naturally not rotate, if the motor failure, the fan motor should be checked, and then troubleshooting.
