Patent number: 11920599Abstract: An electric submersible pump includes a plurality of centrifugal pump stages, each stage including a rotating impeller and a stationary diffuser mounted on a shaft coupled to a motor. An upthrust washer can be disposed axially between an impeller and its associated diffuser at or near a tip of the impeller, and the gap between the impeller tip and diffuser can define the end play or axial clearance for the pump. If the upthrust washer wears away, upthrust rubbing occurs at the impeller tip instead of proximate the pump shaft to advantageously help protect the shaft from damage or failure related to heat. In some ESPs, an upthrust bearing assembly can be located at the pump head. A downthrust washer can be disposed in an upstream facing groove of the impeller. The downthrust washer can have a thickness greater than 0.10 in.Type: GrantFiled: September 18, 2020Date of Patent: March 5, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Raju Ekambaram, Teng Fei Wang, Pradeep Mahadevan, Kean Wee Cheah, David Milton Eslinger
