Shengong vacuum -- measures to reduce bearing deformation of Roots vacuum pump

Addtime: 2020-07-18 Browse times: 2006

The bearing of Roots vacuum pump is the key to support the normal operation of the whole equipment. In order to avoid the failure caused by deformation, it is necessary to take corresponding measures.


1. The deformation of the bearing hole of Roots vacuum pump was measured.


2. Process the closed roots vacuum pump to the theoretical size.


3. After the upper and lower boxes of the unit are buckled together, the actual bearing holes are oval long holes with the long axis equal to the theoretical hole diameter, while the horizontal hole diameter is slightly smaller than the theoretical hole diameter.


4. According to the deformation of the long axis T, the thickness of T value is removed from the upper and lower surfaces of the unit.


5. Machine other bearing positions to theoretical dimensions.


6. After machining, the bolt hole of bearing cover will be dislocated with the bolt hole of box. The bearing cover can be reamed or the bearing hole of the box body can be re manufactured after mapping.


The above measures reduce the bearing deformation of Roots vacuum pump, improve the performance of the whole unit, hope to help you.
