Abstract
A housing for use in high-pressure fluid applications, and in particular a structure for the fluid end of a multi-cylinder reciprocating pump used in oilfield, wherein the structure includes features such as ruled surfaces and increased sidewall thickness to improve resistance to stress applied and has an extended the service life.
Claims7
A fluid end for a multiple-cylinder reciprocating pump, the fluid end comprising:
- a housing having:
- at least three plunger bores, each with a plunger-bore centerline wherein the plunger-bore centerlines are parallel and coplanar such there are neighboring plunger bores, and wherein the distance between neighboring plunger-bore centerlines are equal;
- a front plane perpendicular to the plunger-bore centerlines;
- a left sidewall having a left-sidewall thickness and a left side plane, which is substantially perpendicular to the front plane;
- and
- a right sidewall having a right-sidewall thickness and a right side plane, which is substantially perpendicular to the front plane and opposes said left sidewall plane, wherein the ratio of the left-sidewall thickness and the distance between neighboring plunger-bore centerlines is from 0.6 to 1.0, and wherein the ratio of the right-sidewall thickness and the distance between neighboring plunger-bore centerlines is from 0.6 to 1.0.
