Reciprocating pump
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.
1. A reciprocating pump comprising:
a power end having a frame;
a fluid end;
a skid support structure integrally formed at a base of the power end frame to provide proper built-in support and rigidity for the pump power end 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 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 of claim 1 , wherein the integrally-formed support structure comprises a plurality of vertical struts forming a series of chambers at the base along front and back of the frame.
4. The reciprocating pump 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 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, where the location of the vertical struts of the inner chambers and the outer chambers is staggered.
6. The reciprocating pump 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 of claim 1 , wherein the integrally-formed crosshead guide tube and noseplate structure are formed from a single structure.
8. The reciprocating pump of claim 1 , wherein at least some components of the pump frame are assembled with external fillet welds.
9. The reciprocating pump of claim 1 , further comprising a crosshead having a wearable coating on its outer surfaces.
10. The reciprocating pump of claim 1 , 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 of claim 1 , further comprising a stay rod assembly having a plurality of stay rods spanning between first and second end plates, where the stay rod assembly joins the power end and the fluid end of the pump.
12. A reciprocating pump comprising:
a frame for a power end;
a skid support structure integrally formed at a base of the power end frame to provide proper built-in support and rigidity for the pump power end;
an integrally-formed noseplate and crosshead guide tube structure; and
wherein the integrally-formed crosshead guide tube and noseplate structure comprises an upper component and a lower component.
13. The reciprocating pump of claim 12 , wherein the integrally-formed support structure comprises a plurality of vertical struts forming a series of chambers at the base along front and back of the frame.
14. The reciprocating pump of claim 12 , 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.
15. The reciprocating pump of claim 12 , 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, where the location of the vertical struts of the inner chambers and the outer chambers is one of staggered and inline.
16. The reciprocating pump of claim 12 , wherein the integrally-formed crosshead guide tube and noseplate structure are formed from a single forging/casting/structure.
17. The reciprocating pump of claim 12 , further comprising a crosshead having a wearable coating on its outer surfaces selected from the group consisting of a leaded bronze, Ni-Al-Bronze, and any other ferrous or non-ferrous material.
18. A reciprocating pump comprising:
a fluid end;
a power end having a frame;
a built-in skid support structure integrally formed along a base of the power end frame to provide proper support and rigidity for the pump power end without altering dimensional envelope and mounting points of the pump frame;
an integrally-formed crosshead guide tube and noseplate structure; and
wherein the integrally-formed skid support structure comprises a plurality of vertical struts forming a series of inner and outer chambers without altering outer dimensions of the power end and where the location of the vertical struts of the inner chambers and the outer chambers is one of staggered and inline.
