Title (EN) TANDEM MOTOR LINEAR ROD PUMP
(FR) POMPE À TIGE LINÉAIRE ET À MOTEURS EN TANDEM
Abstract:
(EN) A tandem motor linear rod pumping apparatus for imparting reciprocating, substantially-vertical motion to a pump rod for a sucker-rod pump. The tandem motor linear rod pumping apparatus includes first and second linear mechanical actuator systems disposed in a single housing. These linear mechanical actuator systems impart and control vertical motion of the pump rod. Each linear mechanical actuator system includes a rack and pinion gearing arrangement. Each rack is operatively connected with two pinions. Each pinion is operatively connected to a motor. Rotation of the two motors in a first direction results in an upward motion of the rack and connected sucker rod pump. Rotation of the two motors in a second direction, opposite the first direction, results in a downward motion of the rack and sucker rod pump. The tandem motor linear rod pumping apparatus includes at least one electronic controller to control the operation of the two motors.
(FR) La présente invention concerne un appareil de pompage à tige linéaire et à moteurs en tandem permettant d'imprimer un mouvement alternatif sensiblement vertical à une tige de pompe pour pompe à tige d'aspiration. L'appareil de pompage à tige linéaire et à moteurs en tandem comprend des premier et second systèmes d'actionneurs mécaniques linéaires disposés dans un seul boîtier. Ces systèmes d'actionneurs mécaniques linéaires impriment et commandent un mouvement vertical de la tige de pompe. Chaque système d'actionneur mécanique linéaire comprend un dispositif d'engrènement à crémaillère et pignons. Chaque crémaillère est fonctionnellement raccordée à deux pignons. Chaque pignon est fonctionnellement raccordé à un moteur. La rotation des deux moteurs dans une première direction produit un mouvement vers le haut de la crémaillère et de la pompe à tige d'aspiration associée. La rotation des deux moteurs dans une seconde direction opposée à la première produit un mouvement vers le bas de la crémaillère et de la pompe à tige d'aspiration. L'appareil de pompage à tige linéaire et à moteurs en tandem comprend au moins un dispositif de commande électronique conçu pour commander le fonctionnement des deux moteurs.
