Abstract
Downhole centrifugal pumps and related components and methods may include diffusers housing impellers and a rotational shaft passing through the impellers to impart rotation to the impellers. Bearings are positioned within at least some of the diffusers to support the rotational shaft during the rotation of the impellers. Coupling pins may be positioned between and engage with the bearings and the at least some of the diffusers to at least partially secure each of the bearings to one of the at least some of the diffusers.
Claims20
A method of assembling a centrifugal pump, the method comprising:
- forming a stack of a plurality of diffusers;
- housing a plurality of impellers in the plurality of diffusers;
- extending a rotational shaft through the plurality of impellers to impart rotation to the plurality of impellers;
- supporting the rotational shaft with a plurality of bearings positioned within the plurality of diffusers;
- and
- positioning coupling pins between the plurality of bearings and the plurality of diffusers to at least partially secure each of the plurality of bearings to restrict relative rotation between the plurality of bearings and the plurality of diffusers.
A method of operating a downhole centrifugal pump, the method comprising:
- impellers;
- rotating impellers on a rotational shaft within diffusers having a body housing the impellers;
- supporting the rotational shaft during the rotation of the impellers with bearings positioned within at least some of the diffusers;
- and
- at least partially securing each of the bearings to the at least some of the diffusers against a rotational force applied to the bearings from the rotation of the rotational shaft with coupling members positioned between and engaged with the bearings and the at least some of the diffusers.
A method of operating a centrifugal pump, the method comprising:
- impellers;
- rotating a shaft coupled to impellers housed in diffusers;
- supporting the rotation of the shaft with bearings positioned within the diffusers during the rotation of the impellers;
- and
- resisting a rotational force applied between the bearings and the diffusers with coupling pins positioned between and engaged with the bearings and the diffusers.
