Abstract: 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.

Abstract: Una válvula tiene un cuerpo que tiene un elemento de válvula giratorio. Un mecanismo impulsor tiene un miembro de entrada impulsor y un miembro de salida impulsor que están acoplados al elemento de válvula para girar el elemento de válvula. Un miembro de corte está operativamente localizado dentro del mecanismo impulsor entre el miembro de entrada impulsor y el miembro de salida impulsor para cortar en caso de que la fuerza para girar el elemento de válvula sea excesiva. La válvula tiene indicios que indican posiciones abiertas y cerradas para el elemento de válvula. Un indicador está montado al miembro impulsor de salida para alinearse apropiadamente con los inicios sin importar si el miembro de corte ha cortado o no.

Abstract: A dual circuit lubrication system for a power end of a reciprocating pump that includes a lubrication pump that supplies lubrication fluid to a high pressure lubrication circuit and a low pressure lubrication circuit. The high pressure lubrication circuit is fluidly coupled to a crankshaft to supply lubrication fluid to sliding surfaces associated with the crankshaft at a first lubrication fluid pressure. The crankshaft drives a crosshead coupled to a plunger to displace fluid from a fluid end of the reciprocating pump. The low pressure lubrication circuit is fluidly coupled to supply the lubrication fluid to a plurality of rolling surfaces associated with the crankshaft at a second lubrication fluid pressure. The first lubrication fluid pressure is greater than the second lubrication fluid pressure.
