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.

摘要： 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.

摘要： A plug valve assembly has a valve body with an inlet and an outlet each defining a fluid passageway in fluid communication with a cavity defined within the valve body. The valve body further has a collar defining a service opening extending upward from the valve body. A plug with a spindle top and a plug body is disposed within the cavity. The plug has an opening that is operable to obstruct the fluid passageway when it is in a closed position and to connect the inlet to the outlet when it is in an open position. The spindle top of the plug has a hexagonal outer profile and a through opening and adaptable to engage with a variety of actuating devices. A threaded cap is removably engaged with the collar of the valve body and is operable to retain the plug within the valve body cavity.

摘要： In some implementations, a powertrain for powering a fluid pump may include a power source configured to rotate a first drive shaft at an approximately constant speed. The powertrain may include a mechanical transmission. The mechanical transmission may include one or more gearboxes associated with a set of fixed gear ratios, a second drive shaft coupled to the first drive shaft, and a third drive shaft coupled to an input drive shaft of the fluid pump and configured to rotate the input drive shaft at variable speeds or with variable torque based on using different gear ratios from the set of fixed gear ratios. The powertrain may include a torque converter disposed between the first drive shaft and the second drive shaft to enable the first drive shaft to be coupled to the second drive shaft.
