Title (EN) INTEGRATED HEAT EXCHANGER AND THRUST BEARING BASE
(FR) ÉCHANGEUR DE CHALEUR INTÉGRÉ ET BASE DE PALIER DE BUTÉE
Abstract:
(EN) A submersible well pump is driven by an electrical motor. A thrust bearing module between the pump and the motor has a base secured to and extending downward from a housing. The base has a motor end connector and an axial bore in fluid communication with lubricant in the motor. A shaft extends through the bore and into the housing. A thrust bearing assembly has a lower end at an upper end of the base. A lubricant pump mounted in the bore and coupled to the shaft pumps lubricant upward into the chamber. A passage has an inlet port in the chamber and an outlet port within the bore for returning lubricant pumped by the lubricant pump. The passage extends internally through the base and has a number of turns encircling the bore.
(FR) L’invention concerne une pompe à puits submersible entraînée par un moteur électrique. Un module de palier de butée entre la pompe et le moteur comporte une base fixée à un boîtier et s'étendant vers le bas à partir de celui-ci. La base comporte un connecteur d'extrémité de moteur et un alésage axial en communication fluidique avec le lubrifiant dans le moteur. Un arbre s'étend à travers l'alésage et dans le boîtier. Un ensemble palier de butée présente une extrémité inférieure au niveau d'une extrémité supérieure de la base. Une pompe à lubrifiant montée dans l'alésage et couplée à l'arbre pompe le lubrifiant vers le haut dans la chambre. Un passage est doté d’un orifice d'entrée dans la chambre et d’un orifice de sortie à l'intérieur de l'alésage pour le retour de lubrifiant pompé par la pompe à lubrifiant. Le passage s'étend à l'intérieur à travers la base et a un certain nombre de spires encerclant l'alésage.
