Title
(EN) UNIVERSAL JOINT WITH COOLING SYSTEM
(FR) JOINT UNIVERSEL À SYSTÈME DE REFROIDISSEMENT
Abstract
(EN) A progressing cavity pump system including a rotor and a stator having an inner cavity. The rotor is rotationally disposed inside the inner cavity of the stator such that rotation of the rotor relative to the stator causes material in the inner cavity to be pumped therethrough. The pump system further includes a universal joint directly or indirectly rotationally coupled to the rotor, and a cooling system thermally coupled to the universal joint and configured to cool the universal joint by active heat exchange at a position remote from the universal joint.
(FR) L'invention porte sur un système de pompe à vis hélicoïdale excentrée qui comprend un rotor et un stator ayant une cavité interne. Le rotor est disposé de façon à pouvoir tourner à l'intérieur de la cavité interne du stator, de telle sorte qu'une rotation du rotor par rapport au stator amène un matériau dans la cavité interne à être pompé à travers celle-ci. Le système de pompe comprend de plus un joint universel couplé directement ou indirectement de façon rotative au rotor, et un système de refroidissement couplé thermiquement au joint universel et configuré de façon à refroidir le joint universel par échange de chaleur actif à un emplacement éloigné du joint universel.
