Title (EN) DEVICE FOR THE CONNECTION OF RODS FOR ROTATIONAL DRIVE OF A DOWNHOLE PUMPING APPARATUS
(FR) DISPOSITIF POUR LA CONNEXION DE TIGES POUR L'ENTRAÎNEMENT EN ROTATION D'UN APPAREIL DE POMPAGE DE FOND DE TROU
Abstract:
(EN) A device for connecting sucker, or drive rods, consisting of a threaded coupling, one end of which has a right hand female thread and the other a left hand female, which joins the threaded pins of adjacent rods. The ends of the pins are equipped with dogs, or lugs, that interlock when the connection is made up, firmly linking the rods torsionally. The coupling serves only to keep the dogs, or lugs, engaged and to carry the tensional load on the connection. Such a connection provides a stronger torsional link between rods than connections currently available. The connection also does not require the special make-up procedure of the current systems and cannot over tighten or back off during operation.
(FR) L'invention concerne un dispositif pour relier des tiges de pompage ou des tiges d'entraînement, constitué d'un raccord fileté, dont une extrémité a un filetage femelle à droite et l'autre extrémité un filetage femelle à gauche, qui relie les broches filetées de tiges adjacentes. Les extrémités des broches sont équipées de taquets, ou d'ergots, qui s'emboîtent lorsque la connexion est réalisée, reliant solidement les tiges en torsion. L'accouplement sert uniquement à maintenir les taquets, ou les ergots, en prise et à supporter la charge de tension sur la connexion. Une telle connexion offre une liaison en torsion plus solide entre les tiges que les connexions actuellement disponibles. La connexion ne nécessite pas non plus la procédure de fabrication spéciale des systèmes actuels et ne peut pas produire un serrage excessif ou un desserrage pendant le fonctionnement.
