    摘要： A fluid end block for a reciprocating pump defines a fluid chamber and a packing bore. An outlet fluid passage is formed in the fluid end block in communication with the fluid chamber and includes an outlet valve. An inlet fluid passage is formed in the fluid end block in fluid communication with the fluid chamber and includes an inlet valve. A plunger is reciprocally disposed in the packing bore. Packing in the packing bore is positioned to contact the plunger and a packing sleeve is disposed between the packing and the packing bore. The packing sleeve is a hollow cylinder with inner and outer surfaces and an inner end configured to be inserted into the packing bore. The inner end includes a bevel extending between the outer surface and the inner end, the outer surface including a notch formed therein adjacent the inner end.

    摘要： A retainer nut assembly for a fluid end of a pump system includes a fastener with a generally cylindrical configuration, first and second ends, external threads configured to engage corresponding threads of a fluid end block, and a cavity formed at the first end. A suction cap is configured to sealingly fit to the fluid end block. A load piston is movably disposed in the cavity adjacent the suction cap. A bore is formed through the fastener in communication with the cavity and provided with hydraulic fluid. A pressure piston is movably disposed in the bore. A threaded passageway is formed through the fastener in communication with the bore and open to the second end. A locking bolt is disposed in the threaded passageway and, when inserted into the threaded passageway, contacts the pressure piston and generates fluid pressure on the load piston.

    摘要： An integrated pump and manifold assembly includes a support structure, a manifold assembly mounted on the support structure, and one or more frac pumps. The manifold assembly includes one or more low pressure lines and a high pressure discharge line including a discharge outlet configured to fluidly couple to a wellhead. The one or more frac pumps are each mounted on the support structure and include a frac pump inlet and a frac pump outlet. The one or more frac pumps are configured to be in fluid communication with the one or more low pressure lines and the high pressure discharge line. The one or more low pressure lines, the high pressure discharge line, and the one or more frac pumps are integrated as a single unit and mounted on the support structure.

    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： An apparatus according to which a power end of a reciprocating pump assembly includes a block having bores formed therethrough, and crossheads disposed in the bores and adapted to reciprocate therein. A lubrication pump is in fluid communication with the bores. The pump is operable to pump lubrication fluid into each of the bores so that the crossheads are lubricated as they reciprocate within their respective bores. In another aspect, a power end includes a crosshead block and a power frame connected thereto, the frame including rib plates and supporting the crosshead block. In yet another aspect, a method includes casting a crosshead block; fabricating rib plates; connecting the rib plates to form a frame; and connecting the cast crosshead block to the frame. In some embodiments, the power ends may be used in oilfield operations such as, for example, the cementing, acidizing, or fracturing of a subterranean wellbore.
