Abstract
An electric submersible pump (ESP) can include a shaft; an electric motor configured to rotatably drive the shaft; a housing; a stack of diffusers disposed in the housing; impellers disposed in the housing and operatively coupled to the shaft; and a proximity sensor operatively coupled to the housing.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . An electric submersible pump (ESP) comprising:
a shaft; an electric motor configured to rotatably drive the shaft; a protector operatively coupled to the electric motor; a housing; a stack of diffusers disposed in the housing; impellers disposed in the housing and operatively coupled to the shaft; and a proximity sensor operatively coupled to the protector.
2 . The ESP of claim 1 wherein the protector comprises a bellows and wherein the proximity sensor comprises a bellows sensor that senses at least one characteristic of the bellows.
3 . The ESP of claim 2 wherein the bellows sensor comprises distance detection circuitry.
4 . The ESP of claim 1 wherein the protector comprises a shaft seal and wherein the proximity sensor comprises a shaft seal sensor.
5 . The ESP of claim 1 wherein the protector comprises a thrust bearing and wherein the proximity sensor comprises a thrust bearing sensor.Join the waitlist — get patent alerts
