Theoretical and Experimental Research on Flow Variation Regularity of Hydraulic-driven Reciprocating Pump
Constitution and work principle of hydraulic-driven reciprocating pump (HDRP for short) with double cylinders and double action is introduced, and flow variation regularity in its sucking and discharging main pipes as well as calculating methods are analyzed in detail. In addition, the specific calculating formula is derived and a systematic experimental research is carried out. The flow curves of sucking and discharging main pipes measured from experiment demonstrate properly theoretical analysis result. The experiment shows that flow variation inside suction and discharging main pipes is smooth and steady, achieving a constant value, which fully reveals excellent hydraulic characteristic of HDRP, However, during accelerating and decelerating of sucking and discharging in hydraulic cylinder, influenced by reversing control precision, ideal superimposition of flow fails to be realized, hence, flow impulse easily occurs inside sucking and discharging main pipes. Piston reversing control accuracy plays an influential role in flow variation regularity of pump, accordingly, it is one of the key techniques to keep HDRP fine output characteristic by designing reasonable stroke reversing control device.
