Abstract
The present disclosure relates to a jet pump tail cone insert for a jet pump. The jet pump tail cone insert comprises a cap, a body and an end member. The end member has a plurality of projections configured to matingly receive a plurality of forks of the body. When connected together, the body and the end member have a plurality of receivers configured to receive stator veins of a bearing hub of the jet pump. The body and the end member are configured to be proximate the stator veins. The cap is configured to matingly couple to the body. The jet pump tail cone insert encompasses a portion of the bearing hub of the jet pump. The jet pump tail cone insert occupies within the bearing hub thereby increasing a flow rate of water through the jet pump.
Claims20
A method of decreasing a flow area within a jet pump, comprising:
- disposing a jet pump tail cone insert encompassing a portion of a bearing hub of the jet pump, said jet pump tail cone insert including:
- an end member having an interior and an exterior opposite said interior, an upper portion and a lower portion opposite said upper portion, a plurality of projections configured to matingly receive a plurality of forks, and a plurality of receivers configured to receive at least one stator vein of said bearing hub;
- a body having an interior and an exterior opposite said interior, an upper portion and a lower portion opposite said upper portion, said plurality of forks configured to matingly attach to said plurality of projections, and a plurality of receivers configured to receive said at least one stator vein of the jet pump, said body is configured to be physically positioned about said at least one stator vein, said lower portion of said body configured to matingly couple to said upper portion of said end member;
- and
- a cap having an interior and an exterior opposite said interior and an upper portion and a lower portion opposite said upper portion, said lower portion of said cap configured to matingly couple to said upper portion of said body;
- and
- wherein said jet pump tail cone insert occupies space proximate said bearing hub thereby increasing a flow rate of water through the jet pump.
A jet pump tail cone insert for a jet pump comprising:
- an end member having an interior and an exterior opposite said interior, an upper portion and a lower portion opposite said upper portion, a plurality of projections configured to matingly receive a plurality of forks, and a plurality of receivers configured to receive at least one stator vein of a bearing hub of the jet pump;
- a body having an interior and an exterior opposite said interior, an upper portion and a lower portion opposite said upper portion, said body having said plurality of forks configured to matingly attach to said plurality of projections of said end member, and a plurality of receivers configured to receive said at least one stator vein of said bearing hub, said body is configured to be proximate said at least one stator vein, said lower portion of said body configured to matingly couple to said upper portion of said end member;
- and
- a cap having an interior and an exterior opposite said interior and an upper portion and a lower portion opposite said upper portion, said lower portion of said cap configured to matingly couple to said upper portion of said body,
- wherein the jet pump tail cone insert encompasses a portion of said bearing hub of the jet pump.
A method of installing a jet pump tail cone insert in a jet pump comprising:
- disposing an end member proximate at least one stator vein of a bearing hub opposite an exterior side of an impeller of the jet pump, said end member having an interior and an exterior opposite said interior, an upper portion and a lower portion opposite said upper portion, a plurality of projections configured to matingly receive a plurality of forks, and a plurality of receivers configured to receive said at least one stator vein;
- matingly coupling a body to said upper portion of said end member, said body having an interior and an exterior opposite said interior, an upper portion and a lower portion opposite said upper portion, said plurality of forks configured to matingly attach to said plurality of projections, and said plurality of receivers configured to receive said at least one stator vein of said bearing hub, said body is configured to be physically positioned proximate said at least one stator vein;
- and
- matingly coupling a cap of the jet pump tail cone insert to said upper portion of said body, said cap having an interior and an exterior opposite said interior and an upper portion and a lower portion opposite said upper portion.
