Title
(EN) TAPERED THRUST BEARING FOR PUMPING SYSTEM
(FR) PALIER DE BUTÉE CONIQUE POUR SYSTÈME DE POMPAGE
Abstract
(EN)
A system includes a drive shaft and a diffuser positioned around the drive shaft to transmit a flow of fluid. The system also includes an impeller that is rotatable with the drive shaft to induce the flow of fluid through the diffuser. Additionally, the system includes a tapered thrust bearing positionable to receive a downhole force from a pumping stage. The tapered thrust bearing includes a flange sleeve positioned around the drive shaft. The flange sleeve includes a tapered mating surface. The tapered thrust bearing also includes a stationary bushing positioned around the flange sleeve. The stationary bushing includes a tapered receiving surface to receive the tapered mating surface of the flange sleeve.
(FR)
L'invention concerne un système, qui comprend un arbre d'entraînement et un diffuseur positionné autour de l'arbre d'entraînement de façon à transmettre un écoulement de fluide. Le système comprend également une hélice qui peut tourner avec l'arbre d'entraînement de façon à induire l'écoulement de fluide à travers le diffuseur. De plus, le système comprend un palier de butée conique pouvant être positionné de façon à recevoir une force de fond de trou à partir d'un étage de pompage. Le palier de butée conique comprend un manchon de bride positionné autour de l'arbre d'entraînement. Le manchon de bride comprend une surface d'accouplement effilée. Le palier de butée conique comprend également un coussinet fixe positionné autour du manchon de bride. Le coussinet fixe comprend une surface de réception effilée pour recevoir la surface d'accouplement effilée du manchon de bride.
