Development and Application of High Pressure Partial Combination-valve-type Hydraulic Unit of Reciprocating Water Injection Pump

Hydraulic unit of reciprocating pump in widespread application at present cracks easily and replacement of valves is difficult. To solve these problems, a partial combination - valve - type reciprocating pump is designed.The original integral hydraulic unit with three cavities integrated together is replaced by a combination hydraulic unit with three autonomous cavities. This kind of design has the advantages of easy hydraulic unit replacment and installation and long working life.
