Title
(EN) ARTICULATED PLUNGER ROD PUMP
(FR) POMPE À TIGE DE PISTON ARTICULÉE
Abstract
(EN) A reciprocating rod pump system, comprising an articulating plunger assembly having a plurality of plunger segments, each having a pin end and a box end, and a ball and socket articulating connector formed between the pin end of one plunger segment and the box end of another plunger segment. The articulating connector is formed from a collar rigidly attached to the pin end, which defines a socket, the collar comprising an internal shoulder which abuts an external shoulder on the plunger pin end, such that the uppermost end of the collar does not contact the plunger segment, and a plunger nipple comprising a ball adapted to fit and rotate within the socket, and a shank which rigidly engages the box end thread of a plunger segment.
(FR) L'invention concerne un système de pompe à tige à mouvement alternatif, comprenant un ensemble piston articulé pourvu d'une pluralité de segments de piston, possédant chacun une extrémité formant broche et une extrémité formant étui, et un connecteur d'articulation à rotule formé entre l'extrémité formant broche d'un segment de piston et l'extrémité formant étui d'un autre segment de piston. Le connecteur d'articulation est formé à partir d'un collier fixé de manière rigide à l'extrémité formant broche, qui définit une douille, le collier comprenant un épaulement interne qui vient en butée contre un épaulement externe sur l'extrémité formant broche du piston, de sorte que l'extrémité supérieure du collier n'entre pas en contact avec le segment de piston, et un mamelon de piston comprenant une bille conçue pour s'ajuster et tourner à l'intérieur de la douille, et une queue qui vient en prise de manière rigide avec le filetage de l'extrémité formant étui d'un segment de piston.
