The existing hydraulic reciprocating pump has the problems of impact of hydraulic system and fluctuation of pump displacement and pressure. Therefore a novel hydraulic triplex pump is schemed. This new pump adopts a uniformly-moving roatry valve to replace the traditional hydraulic reversing valve, and uses 2 separate hydraulic oil pumps for suction and discharge strokes respectively. It can reduce effectively the impact of the hydraulic system and is able to run with constant displacement. The points for attention in the design of the pump are indicated.
