Adjustment of cross-flow in multi-stage shielded pumps
Thread Content
In a symmetric multi-stage shielded pump like this, thrust bearings are present at both ends; why then is there a shaft play of 1 mm after installing the balance disk? Could it be that the clearances of the thrust bearings at both ends are quite large? Could any expert give some guidance?
For devices of this type, it is essential to follow the specifications provided by the manufacturer. The clearance of the thrust bearing is adjustable, and this is usually achieved using shims. For reference.
The axial play of this pump can reach 1.5 mm
Thank you; it seems that the gap between the thrust disc and the thrust bearing is also quite large
Learn*, learn* – many experts post comments
The thrust disc is also part of the thrust bearing assembly; there’s so much you need to learn
