摘要： A reciprocating pump has a driven crankshaft and a connecting rod having an aft end rotatably mounted to the crankshaft. The pump has a stationarily mounted crosshead case in which a crosshead assembly strokes. The crosshead assembly has first and second crosshead members. A retainer pivotally joins the forward end of the connecting rod to the first crosshead member. The second crosshead member has a partially cylindrical recess containing a bushing. The forward end of the connecting rod is in pivotal engagement with the bushing. The second crosshead member is releasably secured to the first crosshead member to allow removal of the second crosshead member and the bushing from the crosshead case without detaching the forward end of the connecting rod from the first crosshead member.

摘要： A reciprocating pump assembly has a pump housing with a crankshaft. A plunger is connected to the crankshaft for pumping a fluid through a cylinder. The cylinder has a fluid inlet port and an opening that provides access to the cylinder. A suction cover is mounted in the opening and has a hub that is coaxial with an axis of the suction cover. A suction valve stop is mounted adjacent one of the fluid ports and has a spring retainer. A column extends from the spring retainer, and a bushing is mounted to the spring retainer for engaging and being retained by the hub of the suction cover. The suction cover guides the suction valve stop in operation and, when the suction cover is removed from the opening, the suction valve stop is removable.

摘要： A pressure relief valve has a housing fluidly connected to a pressurized system line carrying a system fluid. The housing carries a moveable piston and a valve member that both move between closed and open positions. The piston defines an upper chamber and a lower chamber within the housing. A pressurized fluid is supplied to the upper chamber to bias the piston toward the closed position. After the relief valve opens from excessive system pressure, the pressurized fluid is injected into the lower chamber to delay the return of the piston to the closed position. Initially, the fluid in the lower chamber flows through a check valve while the piston returns to the closed position. Then the fluid vent in the lower chamber vents from the lower chamber as the piston and valve member approach the closed position.
摘要翻译：减压阀具有流体连接到承载系统流体的加压系统管线的壳体。壳体承载两个在关闭位置和打开位置之间移动的可移动活塞和阀构件。活塞在壳体内限定上室和下室。加压流体被供应到上室以将活塞偏压到关闭位置。在安全阀从系统压力过大开启之后，加压流体被注入到下腔室中以延迟活塞返回关闭位置。最初，当活塞返回到关闭位置时，下室中的流体流过止回阀。然后当活塞和阀构件接近关闭位置时，下部腔室中的流体通风口从下部腔排出。
