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.
摘要翻译：往复泵具有从动曲轴和具有可旋转地安装在曲轴上的后端的连杆。泵具有固定的十字头箱体，十字头组件在其中行进。十字头组件具有第一和第二十字头构件。保持器将连杆的前端枢转地连接到第一十字头构件。第二十字头构件具有包含衬套的部分圆柱形凹部。连杆的前端与衬套枢转接合。第二十字头构件可释放地固定到第一十字头构件，以允许将第二十字头构件和衬套从十字头壳体移除，而不将连杆的前端从第一十字头构件分离。

摘要： A reciprocating pump assembly has a pump within a housing. The pump has a crankshaft that rotates and a crosshead that is connected to a plunger via a pony rod. The plunger pumps fluid through cylinders in the pump. A connecting rod connects at one end to the crankshaft and at another end to the crosshead to translate the crankshaft's rotational movement into linear movement of the crosshead and thereby the plunger. The end connected to the crosshead is secured to the crosshead by a bushing located within the crosshead that allows the connecting rod end to pivot during operation. The bushing extends more than 180 degrees, retaining the connecting rod with the crosshead without the need for a wrist pin. The end secured by the bushing can be retained within the bushing by a lock plate, and retainers without the need for a wrist pin.
摘要翻译：往复泵组件在壳体内具有泵。泵具有旋转的曲轴和经由小马杆连接到柱塞的十字头。柱塞通过泵中的气缸泵送流体。连杆在一端连接到曲轴，另一端连接到十字头，以将曲轴的旋转运动转换成十字头的线性运动，从而将柱塞平移。连接到十字头的端部通过位于十字头内的衬套固定到十字头上，该衬套允许连杆端部在操作期间枢转。套管延伸超过180度，将连杆用十字头固定，无需腕针。通过衬套固定的端部可以通过锁定板和保持器保持在衬套内，而不需要腕针。

摘要： A frame for supporting a pressure relief valve located within a frac line connected to high pressure pumps on frac tracks. A metallic base is formed from rectangular tubing in the shape of a box. Saddles on the base support a tee on the lower portion of the relief valve. Brace links axe connected at one end to the corners of the metallic base and swivel about clevises to allow access to the pressure relief valve. The other end of the brace links connect to clevises on a flange when assembled. The flange is rigidly connected to an upper portion of the relief valve to stabilize the assembly. Lifting loops on the flange allow the frame to be lifted during assembly.
摘要翻译：用于支撑压力释放阀的框架，该压力释放阀位于与压裂轨道上的高压泵相连的压裂线内。金属底座由箱形的矩形管形成。基座上的鞍座支撑安全阀下部的三通。支架连杆在一端连接到金属底座的角部，并在支架上旋转以允许进入泄压阀。组装时，支架连杆的另一端连接到法兰上的U形夹。凸缘刚性地连接到安全阀的上部，以稳定组件。法兰上的起吊环可以在装配过程中使框架抬起。

摘要： A reciprocating pump assembly having a pump within a housing. The pump having a crankshaft that rotates and a crosshead that is connected to a plunger via a pony rod. The plunger pumps fluid through cylinders in the pump. A connecting rod connects at one end to the crankshaft and at another end to the crosshead to translate the crankshaft's rotational movement into linear movement of the crosshead and thereby the plunger. The connecting rod is fabricated from multiple pieces, with the body of the connecting rod fabricated out of light weight aluminum and the end connected to the crosshead fabricated out of steel. The steel end of the connecting rod can withstand the stress at the crosshead. The lighter weight of the connecting rod lightens the weight of the pump and its transportation is easier and less costly.
