Abstract
A fluid end includes a housing having a bore configured to receive a closure element, the bore extending through the housing along an axis and including a wall comprising first threads and a retainer configured to be positioned in the bore of the housing. The retainer includes second threads configured to engage with the first threads of the wall of the housing, and a lateral surface area of the wall of the housing and/or of the retainer is greater than 531 square centimeters.
Claims20
A retainer of a fluid end, the retainer comprising:
- a threaded portion configured to engage with threads of a wall of the fluid end, the wall defining a bore in which the retainer is configured to be inserted, the threaded portion extending from a first end to a second end, the first end is configured to lead insertion of the retainer into the bore, and a distance between a center of gravity of the retainer and the second end is less than 10% of a diameter of the threaded portion to provide sufficient rigidity of the retainer to withstand rotation relative to the wall of the fluid end while the threaded portion is engaged with the threads of the wall.
A fluid end of a reciprocating pump, the fluid end comprising:
- a housing having a bore extending along an axis from a pumping chamber of the housing to an external surface of the housing, the bore comprising a wall with threads configured to engage a retainer installed in the bore, wherein the wall comprises a first diameter and extends a length along the axis;
- and
- a reciprocating element extending along the axis and comprising a second diameter, wherein a ratio between the first diameter of the wall and the second diameter of the reciprocating element is greater than 1.9 to secure the retainer in the bore.
A fluid end of a reciprocating pump, the fluid end comprising:
- a housing having a bore extending along an axis from a pumping chamber of the housing to an external surface of the housing, the bore comprising a wall with first threads;
- a retainer comprising a threaded portion configured to engage the first threads of the wall while installed in the bore, wherein the threaded portion extends a length along the axis while engaged with the first threads of the wall;
- and
- a reciprocating element extending along the axis and comprising a diameter, wherein a ratio between the length of the threaded portion of the retainer and the diameter of the reciprocating element is greater than 0.9 to secure the retainer in the bore.
