Abstract

A skid for supporting a reciprocating pump assembly, the reciprocating pump assembly including a power end frame assembly having a pair of end plate segments and a plurality of middle plate segments disposed between the end plate segments. The end plate segments each have at least a pair of feet and the middle plate segments each having at least one foot. The skid includes a base and a plurality of pads extending from the base. At least a portion of the plurality of pads correspond to the end plate segment feet and at least another portion of the plurality of pads correspond to the at least one foot of each middle plate segment.

Claims

1. A skid for supporting a reciprocating pump assembly, the reciprocating pump assembly comprising a power end frame assembly having a pair of end plates and a plurality of middle plates disposed between the end plates, the end plates each having at least a pair of feet and the middle plates each having at least one foot, the skid comprising:

a base having a pair of side segments including a top wall, a bottom wall, and a sidewall extending between the top and bottom walls forming a c-shaped channel;

at least one transverse segment coupled to and extending between the pair of side segments;

a plurality of spaced apart gussets disposed within the channels, the gussets extending between and connecting to the bottom wall and the top wall of the c-shaped channel; and

a plurality of spaced apart pads extending from the base, the plurality of pads corresponding to the end plate feet and at least another portion of the plurality of pads corresponding to the at least one foot of each middle plate.

2. The skid of claim 1, wherein the plurality of pads have different thicknesses to accommodate bending of the base such that a top surface of each of the plurality of pads lies in substantially the same plane.

3. The skid of claim 1, wherein the spaced apart gussets are vertically secured within the channel so as to perpendicularly intersect the top and bottom walls.

4. The skid of claim 1, wherein the spaced apart gussets intersect the top and bottom at a non-perpendicular angle.

5. The skid of claim 1, wherein a portion of the spaced apart gussets intersect the top and bottom walls at a non-perpendicular angle and a portion of the spaced apart gussets intersect the top and bottom walls a perpendicular angle.

6. The skid of claim 1, wherein the at least one transverse segment is hollow.

7. The skid of claim 1, wherein the at least one transverse segment comprises three transverse segments extending between and connecting the pair of side segments.

8. The skid of claim 7, wherein the transverse segments are parallel.

9. The skid of claim 1, wherein the bottom wall includes at least one mounting opening to enable the skid to be secured to a support structure.

10. A method of mounting a reciprocating pump assembly to a support skid, the reciprocating pump assembly including a pair of end plate segments and at least one middle plate segment disposed between the end plate segments, the end plate segments each having at least a pair of feet and the at least one middle plate segment having at least one foot, the method comprising:

forming a base section, wherein forming the base section includes providing a pair of side segments having a c-shaped channel therein and securing respective ends of at least one transverse segment to the pair of side segments;

securing a plurality of spaced apart gussets within the c-shaped channels, the gussets extending between a bottom wall and a top wall of the c-shaped channel;

securing a plurality of pads to the base section, the plurality of pads corresponding to the feet on the pair of end segments and the at least one foot on the at least one middle plate segment;

aligning the feet of the pump assembly with a corresponding pad on the base section; and

securing the feet of the pump assembly to the base section.

11. The method of claim 10, wherein, prior to securing the feet to the base section, the method comprises machining the plurality of pads such that a top surface of each pad lies in substantially the same plane.

12. The method of claim 10, further comprising machining the feet of the pump assembly such that a bottom surface of each of the feet lies in substantially the same plane.

13. The method of claim 10, further comprising securing a reinforcing plate to at least one side segment.

14. The method of claim 10, wherein providing at least one transverse segment comprises providing at least one transverse segment in the form of an I-beam.

15. The method of claim 10, wherein providing the at least one transverse segment member comprises providing at least one transverse segment having a hollow interior.

16. A reciprocating pump assembly comprising:

a power end frame assembly having a pair of end plate segments and a plurality of middle plate segments disposed between the end plate segments, the end plate segments each having at least a pair of feet and the middle plate segments each having at least one foot;

a base forming a support surface having a pair of side segments and a transverse segment connecting to and extending between the pair of side segments, the pair of side segments including a top wall, a bottom wall, and a sidewall extending between the top and bottom walls forming a c-shaped channel;

a plurality of spaced apart pads extending from the support surface, the plurality of pads corresponding to the feet on the end plate segment and at least another portion of the plurality of pads corresponding to the at least one foot of each middle plate segment, the pads disposed between the support surface and the respective feet on the power end frame assembly.

17. The reciprocating pump assembly of claim 16, further comprising a plurality of spaced apart gussets disposed within the c-shaped channels, the gussets extending between and connecting to the bottom wall and the top wall of the c-shaped channel.

18. The reciprocating pump assembly of claim 16, wherein the plurality of spaced apart pads have different thicknesses to accommodate bending of the base such that a top surface of each of the plurality of pads lies in substantially the same plane.

19. The reciprocating pump assembly of claim 16, wherein the spaced apart gussets are vertically secured within the channel so as to perpendicularly intersect the top and bottom walls.

20. The reciprocating pump assembly of claim 16, wherein the bottom walls of the side segments include at least one mounting opening to enable the skid to be secured to a support structure.
