摘要： An example system includes a fluid end having a block, a suction bore formed in the block, a suction valve seat disposed within the suction bore, and a suction valve disposed within the suction bore, the suction valve, in a closed position, being configured to contact the suction valve seat to seal the suction bore. The system also includes a rod configured to engage the suction valve, the rod being moveable between a first position and a second position, wherein in the first position the suction valve is in the closed position, and in the second position, engagement of the rod with the suction valve causes the suction valve to be in an open position.

摘要： A pinion shaft assembly for operation in a power end of a reciprocating pump includes a tubular member coupled to first pinion gear member via an interference coupling extension, possibly having a protruding alignment key operable to engage a slot formed on an inner wall of the first end of the tubular member to ensure correct rotational orientation of the first pinion gear member and the tubular member and to help prevent rotation of the first pinion gear member relative to the tubular member. The tubular member is also coupled to a second pinion gear member via an interference coupling extension, possibly having a protruding alignment key operable to engage a slot formed on an inner wall of the second end of the tubular member to ensure correct rotational orientation of the second pinion gear member and the tubular member and to help prevent rotation of the second pinion gear member relative to the tubular member.

摘要： A valve assembly and system, method, and apparatus thereof can comprise a valve body having a side surface and a valve body contact surface; a ring surrounding the valve body such that an inner surface of the ring is slidably engaged with the side surface of the valve body; and a retainer at an upper surface of the ring and movable with the ring relative to the valve body such that the retainer moves with the ring as the ring slides along the side surface of the valve body.
