摘要： A retaining assembly for coupling a fluid end component to a fluid end casing. The retaining assembly includes a pair for clamp members, each of which has a pair of rails that define a wedge-shaped groove therebetween. The groove applying an increasing amount of pre-load force or tension to a flange of the fluid end components and a flange of the fluid end casing to drive them together. The amount of pre-load tension applied can vary and can be determined by the user and amount of tightening of the clamp members.

摘要： A cradle plate for high pressure reciprocating pumps is installable within a cradle disposed between a power end of a high pressure reciprocating pump and a fluid end of the high pressure reciprocating pump. The cradle plate has a main body that extends from a front surface to a back surface and a first set of openings that extend through the main body. The first set of openings are configured to receive a set of elongate couplers that position the cradle plate within the cradle in a position that secures a fluid end component against a casing of the fluid end, against a seal of the fluid end, or against both the casing and the seal.

摘要： A fluid end of a reciprocating pump includes multiple bores formed therein, and adjacent bores intersect each other. The intersection of two adjacent bores forms an intersection corner, which is where a concentration of high stress occurs during operation of the pump. A novel geometrical shape or geometry of the intersection corner reduces the concentration of stress on the intersection corners. By improving the shape and geometry of the intersection corner, the impact and concentration of the stress can be reduced, thereby improving or lengthening the lifetime of the material in that intersection corner of the fluid end.

摘要： A sealing assembly for a fluid end of a reciprocating pump is installable within a segment of a casing of the fluid end and is arranged to form a seal with the segment. The sealing assembly includes a closure element and a seal element. The closure element has a sealing portion with a lateral surface that faces an interior wall of the segment of the fluid end. The seal element is sized to be installed around the closure element and includes a seal and one or more seal carriers. The seal is configured to form a seal between the lateral surface of the closure element and the interior wall of the segment. The one or more seal carriers are configured to position the seal with respect to the closure element.

摘要： A valve component utilized in a fluid end assembly of a high pressure reciprocating pump includes a valve body and a sealing element. The valve body defines a recess configured to receive the sealing element. The sealing element is composed of a fiber reinforced material. The valve component is configured to be disposed in a closed position with respect to a valve seat such that a sealing surface of the sealing element engages with a corresponding sealing surface of the valve seat in the closed position.

摘要： An annular scraper ring assembly for a packing arrangement is disclosed. The annular scraper ring assembly can form a seal with a plunger included in a fluid end of a reciprocating pump and includes two or more rings, including a first ring and a second ring. The first ring is formed from a resilient material configured to form a seal against a plunger included in a fluid end of a reciprocating pump and includes an upstream face and an inner surface. The second ring defines a caroming surface configured to engage the upstream face of the first ring and cam the inner surface inwards when the first ring is compressed against the second ring.

摘要： A piston assembly for a reciprocating pump comprises a piston disposed within a liner, a flange extending radially outward from the liner, and a hollow cylindrical end part insertable into a bore in a fluid end of the reciprocating pump. A groove is formed about a circumference of an outer surface of the hollow cylindrical end part and is positioned to face a cylindrical, inner side wall of the bore in the fluid end when the end part is inserted into the bore. A seal element is seated in the groove and is configured to protrude radially outward therefrom. The seal element includes a sealing surface oriented generally parallel to a longitudinal axis of the hollow cylindrical liner to form a seal between the end part of the piston assembly and the cylindrical, inner side wall of the bore when the end part is inserted into the bore.
