摘要： A piston with an integrated heat exchanger comprises a seal, a piston hub and a piston rod. The piston hub is further provided with a coolant reservoir and an outlet nozzle at its lateral surface. The heat exchanger integrated into the piston hub and/or the piston hub include a coolant manifold, a coolant passage communicating thereto, and a plurality of channels connecting to the coolant manifold and extending radially to the annulus. Said heat exchanger provides enhanced efficiencies of heat-exchange and debris-flushing.

摘要： A new pump design is described. The pump features a casing with a continuous enclosure extending from a power end of the casing to a fluid end of the casing for housing the reciprocating assembly of the pump, which includes a crankshaft, a plurality of control rods coupled to the crankshaft, and a plurality of crossheads coupled to the control rods. A detachable lid is attached to the casing at the power end and the fluid end of the casing, and encloses the reciprocating assembly. An alignment plate oriented substantially parallel to a stroke axis of the pump maintains alignment of the crossheads.

摘要： The disclosure herein generally relates to sealing elements for valves and methods for forming the same. A valve component has a body which includes a guide portion, a stem, and a sealing portion between the guide portion and the stem. The sealing portion has a front surface facing the guide portion, a back surface facing the stem, and a recess for a sealing element formed in a periphery of the sealing portion; and one or more passages extending between the back surface of the sealing portion and the recess.
