Design and Control of the Hydraulic Reciprocating Pump

Jia Guang-zheng, Wang Xuanyin

Abstract

Abstract The reciprocating pumps are widely used for transporting fluid in oil field. The flow pulsation and pressure fluctuation in the conventional reciprocating pump with short stroke, high speed and simple harmonic motion of piston driven by crank-connecting rod mechanism are inevitable. For reducing the flow and pressure pulsation, a hydraulic reciprocating pump with the GPCM control by means of normal on-off valve is designed. In order to improve the overall pump performances and life span. fault analysis and optimized design of the pump valve are completed. The mathematical model of the asymmetric cylinder system with PCM valve control used in the hydraulic reciprocating pump is built. The digital simulation about the control system is done, and the result shows that the pulsation of pump discharge flow is improved greatly.
