Abstract
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.
Claims40
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;
- and
- a 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.
17-27. (canceled)
A method for operating a progressing cavity pump system comprising:
- accessing a progressing cavity pump including a rotor and a stator having an inner cavity, wherein said rotor is positioned inside said inner cavity, said pump further including a universal joint directly or indirectly rotationally coupled to said rotor;
- causing said rotor to rotate relative to said stator to cause materials in said inner cavity to be pumped therethrough;
- and
- cooling said universal joint, during said causing step, by active heat exchange at a position remote from said universal joint passing a fluid about said universal joint or about said pump at a position external of said inner cavity that is axially aligned with at least part of said universal joint.
A joint system comprising:
- a first shaft configured such that at least part of said first shaft rotates generally eccentrically;
- a second shaft rotationally coupled to said first shaft;
- a universal joint rotationally coupling said first and second shafts;
- and
- a cooling system thermally coupled to said universal joint at a position that is axially aligned with at least part of said universal joint and configured to cool said universal joint by active heat exchange at a position remote from said universal joint.
A progressing cavity pump system 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;
- a universal joint directly or indirectly rotationally coupled to said rotor, wherein said universal joint is fluidly isolated from said inner cavity;
- and
- a cooling system configured to circulate fluid in a manner such that said fluid provides cooling to said universal joint.
(canceled)
A progressing cavity pump system 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;
- a universal joint directly or indirectly rotationally coupled to said rotor;
- and
- a cooling system including a plurality of fins thermally coupled to said universal joint and configured to cool said universal joint.
