Optimal Desigh of Self-Sealing Low Friction and Non-Leakage Plunger Pump

Abstract:

A new type of wear-resistant hydraulic feedback self-sealing plunger pump is proposed. finite element analysis and optimal design of orthogonal parameters are applied to determine the structural parameters. The pump overcomes the conventional piston friction, low efficiency, short life. Laboratory tests showed that the pump free down stroke, full returns, leakage reduction 1,000 times than the standard API. Field experiments indicate that pump efficiency attain to 60-80%, achieved a good energy saving effect of improving the pump efficiency.
