UNIVERSAL JOINT WITH COOLING SYSTEM

摘要

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.

1. A progressing cavity pump system comprising:
a pump comprising:
a rotor;a stator having an inner cavity, said rotor being rotationally disposed inside said inner cavity of said stator such that rotation of said rotor relative to said stator causes material in said inner cavity to be pumped therethrough; anda universal joint directly or indirectly rotationally coupled to said rotor; and a cooling system thermally coupled to said universal joint and configured to cool said universal joint by active heat exchange at a position remote from said universal joint pass a fluid about said universal joint or about said pump at a position external of said inner cavity, wherein said position is axially aligned with at least part of said universal joint to provide cooling thereto.
