Abstract
A power end frame of a reciprocating pump includes a plate and a ring configured to couple to the plate in an assembled configuration of the power end frame. The ring and the plate cooperatively define a compartment of an interior of the power end frame configured to enclose a crankshaft of the reciprocating pump, the ring includes a base surface and a flange extending from the base surface such that an interface surface of the flange is offset from the base surface, the base surface faces the compartment of the power end frame, and the interface surface is configured to abut the plate in the assembled configuration.
Claims20
A power end of a reciprocating pump, the power end comprising:
- a ring defining a compartment of an interior of the reciprocating pump, wherein the ring comprises a base surface and a flange, the base surface faces the compartment, and the flange comprises:
- an extended portion extending away from the base surface, wherein an interior surface of the extended portion faces the compartment, and an exterior surface of the extended portion is disposed opposite the interior surface;
- and
- an interface surface extending between the interior surface and the exterior surface;
- and
- a plate comprising a lateral surface, wherein the interface surface of the ring is configured to abut the lateral surface of the plate such that the interior surface of the ring is offset from the plate.
A power end frame of a power end of a reciprocating pump, the power end frame comprising:
- a ring comprising a base surface and a flange, wherein the flange comprises:
- an arcuate portion extending from the base surface;
- and
- an extended portion extending away from the base surface, wherein the extended portion comprises a first interior surface defining at least a portion of a compartment of an interior of the power end frame, the extended portion comprises a first exterior surface opposite the first interior surface, and the first exterior surface and the first interior surface extend to an interface surface;
- and
- a plate comprising:
- a second interior surface defining at least another portion of the compartment;
- a second exterior surface opposite the first interior surface;
- and
- a lateral surface extending between the second interior surface and the second exterior surface, wherein the lateral surface is configured to abut the interface surface of the ring such that the first interior surface and the second interior surface are offset from one another.
A method of manufacture of a power end frame of a reciprocating pump, the method comprising:
- providing a ring, wherein the ring comprises:
- a base surface facing a compartment of the power end frame;
- and
- a flange comprising an arcuate portion extending from the base surface, an extended portion extending from the arcuate portion and comprising an interior surface defining at least a portion of the compartment and an exterior surface opposite the interior surface, the interior surface and the exterior surface extending to form an interface surface having a reduced dimension between the interior surface and the exterior surface;
- abutting the interface surface of the flange of the ring against a plate such that the interior surface of the flange is offset from the plate;
- and
- applying a weld along the flange to penetrate the interface surface of the flange to secure the ring and the plate to another.
