摘要： An arrangement for supporting one or more bearings of a crankshaft assembly of a hydraulic fracturing pump includes a frame and one or more bearing supports. The frame is of a first material and defines one or more bearing support profiles. The bearing supports are of a second material different from the first material of the frame. The bearing supports are cast-in-place within the corresponding bearing support profiles of the frame and are configured to be in contact with an outer race of the corresponding bearings of the crankshaft assembly. Compared to the first material of the frame, the second material of the bearing supports is more effective at preventing slippage of the bearings.

摘要： In some implementations, a flowline connector assembly may include a first flowline member having a first cylindrical passageway, and a second flowline member having a second cylindrical passageway. The flowline connector assembly may include a pin, configured to be inserted into the first cylindrical passageway and the second cylindrical passageway, including a stop extending radially outward from an outer surface of the pin, where a first side of the stop is configured to contact a face of the first flowline member when the pin is inserted into the first cylindrical passageway. The flowline connector assembly may include a collar configured for threaded engagement at a first end with an outer surface of the first flowline member, wherein an inner surface of the collar is configured to contact a second side of the stop to connect the first flowline member with the second flowline member.

摘要： An intermittent flushing plunger packing assembly is described herein. The packing assembly includes a plurality of annular seals disposed about the plunger configured to reciprocate along a linear axis within the fluid bore of the pump, and an annular packing nut disposed circumferentially about the plunger and configured to retain the plurality of annular seals and adjust a combined height of the plurality of annular seals. A selected one of the plurality of annular seals proximate to the fluid cylinder of the pump has a flushing fluid chamber in fluid communication with a flushing fluid port coupled to a first one-way check valve allowing a pressurized flushing fluid to be introduced and retained within the flushing fluid chamber and creating a fluid barrier to prevent frac fluid in the fluid cylinder from bypassing the annular seals.

摘要： A fluid end of a reciprocating pump assembly includes a cylinder, a cover, and a valve stop. The cylinder has a fluid inlet, a fluid outlet, and an access side wall comprising an access wall inner surface that defines an access opening. The access opening provides access to an inner area of the cylinder and has an access opening axis. The cover is positioned in the access opening and forms a seal with the access wall inner surface along the access opening. The cover includes a cover axis coaxial with the access opening axis. The valve stop is positioned partially in the fluid inlet and includes a spring retainer and a column portion. The column portion includes a flange positioned between the cover and the access wall inner surface. The flange is in the shape of an arc.

摘要： A clapper comprises a first valve body piece, a second valve body piece, wherein the second valve body piece is separate from the first valve body piece, and a seal. The first valve body piece has a seal groove. The second valve body piece has an angled edge. The seal is disposed in the seal groove of the first valve body piece. When the first and second valve body pieces are coupled together, radial compression of the seal between the seal groove and the angled edge causes the seal to be retained within the clapper.

摘要： 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.

摘要： A valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, wherein the inlet and outlet passageways fluidly communicate with the internal region. A valve seat is positioned within the internal region defining a fluid passageway. A hanger is connected to the valve body. A linkage assembly is pivotally and rotatably to the hanger and a valve member is pivotally connected to the hanger via the linkage assembly, wherein the valve member is movable between an open configuration, in which fluid flow is permitted through the fluid passageway, and a closed configuration, in which the valve member engages the valve seat to at least partially restrict fluid flow through the fluid passageway.

摘要： A valve assembly for use in a fracturing pump including a valve member movable into and out of engagement with a valve seat body. The valve seat body includes an outer surface and an inner surface, the inner surface forming a fluid bore extending between a first end and a second end of the valve seat body. The body further includes a seating surface extending radially from the inner surface and facing the valve member, the seating surface having a recessed area. An insert is disposed in the recessed area forming at least a portion of the inner surface and at least portion of the seating surface. The valve seat body first end has a diameter different from a diameter valve seat body second. The difference between diameters allows the valve seat body outer surface to be supported by the fluid passageway.
