Abstract:
A power end frame assembly for a reciprocating pump that includes a first and second end plate segment each including annular bearing support surfaces configured to support a crankshaft bearing assembly. At least one middle plate segment is disposed between the first and second end plate segments and includes an annular bearing support surface configured to support a crankshaft bearing assembly. The annular bearing support surfaces of the first and second end plate segments and the at least one middle plate segment each have a diameter and are coaxially aligned. The diameter of at least one of the first and second end plate segments is different from the diameter of the at least one middle plate segment to facilitate insertion and removal of the crankshaft bearing assembly from the power end frame assembly.

According to one aspect, a manifold assembly includes a skid, a low pressure manifold connected to the skid, and a high pressure manifold connected to the skid. In another aspect, the high pressure manifold has a modular configuration so that the high pressure manifold is disconnectable in whole or in part from the skid, and reconnectable in whole or in part to the skid. In yet another aspect, the high pressure manifold includes high pressure modules, all of which are in fluid communication with each other and each of which is adapted to be in fluid communication with at least one pump. In still yet another aspect, the low pressure manifold includes one or more flow lines, the high pressure manifold includes fittings, and the manifold assembly includes vibration isolators to dampen dynamic loading, the vibration isolators being disposed between the fittings and the one or more flow lines.
Abstract:
A reciprocating pump assembly having a power end housing and a fluid end housing and a cylinder having at least a portion within the power end. A plunger assembly reciprocates between the power end housing and the fluid end housing of the pump assembly, the plunger assembly having a crosshead, a first section limited to movement within the power end and a second section moveable within the fluid end housing. The pump assembly also includes a seal housing disposed within the cylinder, the seal housing having a proximal end adjacent an entrance to the cylinder, and a distal end disposed within the cylinder. A power end seal is secured to the seal housing proximate the distal end and a fluid end seal is disposed within the fluid end housing. The power end seal sealingly engages an outer surface of the first section and the fluid end seal sealingly engages an outer surface of the second section such that during the reciprocating movement of the plunger assembly, fluid end proppant is deterred from contaminating the outer surface of the first section and thus, contaminating the power end seal.
Abstract:
A fluid end 15 for a multiple reciprocating pump assembly 12 comprises at least three plunger bores 61 or 91 each for receiving a reciprocating plunger 35, each plunger bore having a plunger bore axis 65 or 95. Plunger bores being arranged across the fluid head to define a central plunger bore and lateral plunger bores located on either side of the central plunger bore. Fluid end 15 has suction valve bores 59 or 89, each suction valve bore receiving a suction valve 41 and having a suction valve bore axis 63 or 93. Discharge valve bores 57 or 87, each discharge valve bore receiving a discharge valve 43 and having a discharge valve bore axis 63 or 93. The axes of at least one of suction 10 and discharge valve bores is inwardly offset in the fluid end from its respective plunger bore axis.
Abstract:
A valve assembly includes a valve body that defines an internal flow passageway between an inlet and an outlet, and a valve seat disposed in the valve body with a sealing surface perpendicular to the flow passageway. The valve assembly further includes a clapper pivotally correlated to the valve seat having a closed configuration extending across the valve seat configured to substantially close off the flow passageway, and an open configuration configured to substantially allow fluid flow in the flow passageway from the inlet to the outlet through the valve body. An annular valve seat seal is disposed within an annular groove formed in a surface of the valve seat, where the annular valve seat seal is disposed at an interface between the valve seat and the clapper when the clapper is in the closed configuration.
Abstract:
A high pressure swivel comprises a first tube; a second tube; and a plurality of balls contained between a plurality of bearing races and a plurality of complimentary bearing races, wherein the first tube and the second tube comprise a carburizing grade micro-alloy steel, wherein the carburizing grade micro-alloy steel comprises a yield strength of greater than about 110,000 psi, a tensile strength of greater than about 130,000 psi, an elongation of greater than about 14%, a reduction area of greater than about 45%, and a longitudinal Charpy v-notch of greater than about 31 ft/lbs longitudinal at about −40° C., and a nickel concentration of less than about 1 wt. %, by weight of the carburizing grade micro-alloy steel, and a carbon content of less than about 0.15 wt. %, by weight of the carburizing grade micro-alloy steel.
Abstract:
A seat removal tool is disclosed for removing valve seats. A seat removal tool having a main rod, actuator rod within the main rod that actuates to cause radially expandable extraction segments to transition between an expanded position and a contracted position. When using the seat removal tool to remove a valve seat, portions of the radially expandable extraction segments may pass through a seat while the valve seat removal tool is in a contracted position. Thereafter, the seat removal tool may transition from the contracted position to an extended position, which grabs the seat. While in the expanded position, the seat removal tool may pull the valve seat from the passage.
Abstract:
A cable-tie carrier is disclosed herein that includes a chip holder with a recess cavity for holding an electronic chip and a cable that is removably attached to the chip holder. The electronic chip stores identification information or testing data that may be used to identify and track the part. External computing devices (e.g., smart phone, tablet, scanner) may access the stored identification information or testing data for a user. The electronic chip is fastened, magnetically attached, or stuck with adhesive to the chip holder to position a transmitter (or antenna) to face out of the recess cavity.
Abstract:
A gearbox is coupled to a power end housing of a reciprocating pump, where the gearbox includes at least one support member having a first end securely affixed to the gearbox, and the at least one support member having a second end securely affixed to an immobile part of the reciprocating pump for supporting the gearbox and resisting movement of the gearbox relative to the reciprocating pump.
Abstract:
A suction cover assembly for a reciprocating pump includes a suction cover nut having a nut face and a thread configured to threadably connect the suction cover nut to a fluid cylinder of the reciprocating pump. The suction cover assembly includes a suction cover having a cover face. The suction cover is configured to be held by the fluid cylinder such that the cover face opposes the nut face of the suction cover nut. The suction cover includes first and second seals having a leakage trap defined therebetween. The leakage trap is configured to trap leakage pressure during operation of the reciprocating pump. The suction cover includes at least one leakage channel that is configured to channel the leakage pressure from the leakage trap to an interface between the cover face and the nut face.
