Research on Medium-high Pressure Reversible Gear Pump with High Efficiency

A kind of medium-high pressure reversible gear pump was studied in order to improve the technology level of reversible gear pump in our country.Through automatic compensations of the axial gap and the radial gap,the leakage of the reversible gear pump was reduced and the efficiency was improved.And the pump actualized reversible work by internally integrating check valves.The research work is of important significance to improve domestic technology of reversible gear pump.
