低冲次双缸软管隔膜泵液压伺服系统的设计与仿真
Design and simulation of a hydraulic servo system for a low-speed dual-cylinder hose-type diaphragm pump
摘要
Abstract
Aiming at the problems of traditional diaphragm pumps,such as high reciprocating frequency,large flow pulsation,and short diaphragm lifespan,which are caused by the crank-link mechanism,this study proposes a novel configuration of a low-reciprocating-frequency hose-type diaphragm pump with dual-cylinder cooperative motion based on full hydraulic drive.By integrating a closed-loop pump-controlled hydraulic system,a U-shaped buffer structure,and a hydraulic accumulator,and combining with AMESim simulation modeling,the advantages of hydraulic drive in terms of flow stability and pressure smoothness are systematically analyzed.The simulation results show that the displacement curves of the two groups of cylinders and the flow curve of the propulsion cylinder change continuously without collision.Meanwhile,after the introduction of the hydraulic accumulator,the flow and pressure fluctuations during system commutation become smaller,and the load pressure fluctuation is controlled within the range of 0.5 MPa.Compared with traditional mechanical diaphragm pumps,this hydraulically driven diaphragm pump has a larger diaphragm volume,a lower operating frequency,and fewer commutation times,which is beneficial for improving the lifespan of the diaphragm and the inlet and outlet check valves.This study provides a theoretical basis and an engineering solution for the design and improvement of high-stability and large-flow diaphragm pumps and experimental prototypes.关键词
