摘要： The fluid end of a reciprocating pump contains a plurality of manifold cylinders for pumping fluid. The fluid end has an improved liner assembly with a shaft, a coaxial piston, and a liner with a liner seal on an outward end. The liner and seal abut an inner wall of the manifold to prevent pressurized fluid leakage between the liner and the manifold. The liner is pressed against the manifold by an adjustment mechanism which is mounted to a housing surrounding the pump. The adjustment mechanism is spaced axially away from the manifold wall and allows the liner to self-adjust to the wall without the need for a liner bushing. A support device is provided for assisting in the vertical alignment of the liner assembly prior to the liner being pressed tightly against the manifold wall.

摘要： An emergency pressure relief valve has a housing fluidly connected to a pressurized system line carrying a system fluid. The housing carries a piston and a valve member which move within the housing between a closed position and an open position. The piston defines an upper chamber and a lower chamber within the housing. A control fluid is supplied to the upper chamber, and the pressure of the control fluid exerts a biasing force to a first side of the piston. The biasing force holds the valve member and piston in a closed position when the pressure of the system fluid is at an acceptable level. As the pressure of the system fluid rises above the acceptable level, the valve member moves to an open position. While the piston moves from the closed position to the open position, a delay fluid is injected into the lower chamber. As the delay fluid is expelled from the chamber, it delays a return of the piston and valve member to the closed position. As the piston and valve member return from the open position to the closed position, the delay fluid in the lower chamber flows to the upper chamber through a check valve carried by the piston.
摘要翻译：紧急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。壳体承载活塞和阀构件，其在壳体内在关闭位置和打开位置之间移动。活塞在壳体内限定上室和下室。控制流体被供给到上室，并且控制流体的压力对活塞的第一侧施加偏置力。当系统流体的压力处于可接受的水平时，偏压力将阀构件和活塞保持在关闭位置。当系统流体的压力升高到可接受的水平以上时，阀构件移动到打开位置。当活塞从关闭位置移动到打开位置时，延迟流体被注入到下腔室中。当延迟流体从腔室排出时，其延迟了活塞和阀构件返回到关闭位置。当活塞和阀构件从打开位置返回到关闭位置时，下腔室中的延迟流体通过活塞承载的止回阀流到上腔室。
