Abstract

A reciprocating pump includes a frame for a power end, a skid support structure integrally formed at a base of the power end frame to provide proper support and rigidity for the pump power end, where the integral skid support structure has a plurality of struts forming a series of chambers.

First claim

What is claimed is:

1. A reciprocating pump power end housing, comprising:
a frame;
a skid support structure integrally formed at a base of the frame to provide support and rigidity for a power end of a reciprocating pump without altering outer dimensions of the power end;
an integrally-formed crosshead guide tube and noseplate structure; and
wherein the integrally-formed skid support structure comprises a plurality of struts forming a series of chambers.

2. The reciprocating pump power end housing of claim 1 , wherein the integrally-formed support structure comprises a plurality of vertical struts forming a series of chambers having a shape selected from the group consisting of rectangular, square, and triangular.

3. The reciprocating pump power end housing of claim 1 , wherein the integrally-formed support structure comprises a plurality of vertical struts forming a series of chambers at the base along a front and a back of the frame.

4. The reciprocating pump power end housing of claim 1 , wherein the integrally-formed support structure comprises a plurality of vertical struts forming a series of inner chambers and a series of outer chambers at the base of the frame.

5. The reciprocating pump power end housing of claim 1 , wherein the integrally-formed support structure comprises a plurality of vertical struts forming a series of inner chambers and a series of outer chambers at the base of the frame, wherein the location of the plurality of vertical struts of the series of inner chambers and the series of outer chambers is staggered.

6. The reciprocating pump power end housing of claim 1 , wherein the integrally-formed crosshead guide tube and noseplate structure comprises an upper component and a lower component.

7. The reciprocating pump power end housing of claim 1 , wherein the integrally-formed crosshead guide tube and noseplate structure are formed from a single structure.

8. The reciprocating pump power end housing of claim 1 , wherein at least some components of the frame are assembled with external fillet welds.

9. The reciprocating pump power end housing of claim 1 , further comprising a crosshead having a wearable coating applied on outer circumferential surfaces of the crosshead.

10. The reciprocating pump power end housing of claim 9 , wherein the wearable coating on the crosshead is selected from the group consisting of a leaded bronze, Ni-Al-Bronze, and any other ferrous or non-ferrous material.

11. The reciprocating pump power end housing of claim 1 , further comprising a stay rod assembly having a plurality of stay rods spanning between first and second end plates, wherein the stay rod assembly couples the power end to a fluid end of the reciprocating pump.

12. A power end of a reciprocating pump, comprising:
a frame;
a skid support structure integrally formed at a base of the frame configured to provide support and rigidity for the power end, the skid support structure including a plurality of substantially vertical struts forming a series of chambers at the base of the frame; and
an integrally-formed noseplate and crosshead guide tube structure, wherein the integrally-formed crosshead guide tube and noseplate structure comprises an upper component and a lower component.

13. The power end of claim 12 , wherein the plurality of vertical struts form a series of horizontally-oriented chambers at the base along a front and a back of the frame.

14. The power end of claim 12 , wherein the integrally-formed skid support structure comprises a plurality of substantially vertical struts forming a series of inner chambers and a series of outer chambers at the base of the frame.

15. The power end of claim 12 , wherein the integrally-formed skid support structure comprises a plurality of vertical struts forming a series of inner chambers and a series of outer chambers at the base of the frame, where the location of the vertical struts of the inner chambers and the outer chambers is one of staggered or inline.

16. A reciprocating pump comprising:
a fluid end;
a power end coupled to the fluid end and having a housing with a frame;
a skid support structure integrally formed along a base of the housing configured to provide support and rigidity for the power end without altering an outer dimensional envelope of the housing; and
an integrally-formed noseplate and crosshead guide tube structure, wherein the integrally-formed skid support structure comprises a plurality of vertical struts forming a series of horizontally-oriented inner and outer chambers without altering outer dimensions of the housing.

17. The reciprocating pump of claim 16 , wherein the location of the plurality of vertical struts of the series of horizontally-oriented inner and outer chambers is one of staggered or inline.
