Title (EN) LOAD SHARING SPRING FOR TANDEM THRUST BEARINGS OF SUBMERSIBLE PUMP ASSEMBLY
(FR) RESSORT DE PARTAGE DE CHARGE POUR PALIERS DE POUSSÉE EN TANDEM D'ENSEMBLE DE POMPE SUBMERSIBLE
Abstract:
(EN) A submersible well pump assembly (15) has upper and lower seal sections (19, 20) connected between the pump (21) and a motor (17). The seal sections have drive shafts (37, 55) with thrust runners (39, 57) that engage thrust bearing bases (33, 53). The upper drive shaft will undergo a limited amount of downward movement toward the lower drive shaft in response to wear of the upper thrust bearing base. A spring (75) between ends of the drive shafts transfers a portion of the down thrust on the upper drive shaft to the lower drive shaft prior to the limited amount of downward movement of the upper drive shaft toward the lower drive shaft being reached. A rigid stop member (71) in the coupling transfers down thrust directly from the upper drive shaft to the lower drive shaft, bypassing the spring, only after the limited amount of downward movement of the upper drive shaft toward the lower drive shaft has been reached.
(FR) L'invention concerne un ensemble de pompe de puits submersible (15), lequel ensemble a des sections de joint supérieure et inférieure (19, 20) reliées entre la pompe (21) et un moteur (17). Les sections de joint ont des arbres d'entraînement (37, 55) dotés de coulisses de poussée (39, 57) qui viennent en prise avec des bases de palier de poussée (33, 53). L'arbre d'entraînement supérieur subit une quantité limitée de mouvement vers le bas vers l'arbre d'entraînement inférieur en réponse à l'usure de la base de palier de poussée supérieure. Un ressort (75) entre les extrémités des arbres d'entraînement transfère une partie de la poussée vers le bas sur l'arbre d'entraînement supérieur à l'arbre d'entraînement inférieur avant que la quantité limitée de mouvement vers le bas de l'arbre d'entraînement supérieur vers l'arbre d'entraînement inférieur ne soit atteinte. Un élément d'arrêt rigide (71) dans l'accouplement transfère la poussée vers le bas directement à partir de l'arbre d'entraînement supérieur jusqu'à l'arbre d'entraînement inférieur, contournant le ressort, uniquement après que la quantité limitée de mouvement vers le bas de l'arbre d'entraînement supérieur vers l'arbre d'entraînement inférieur a été atteinte.
