摘　　要：针对传统定量泵控制的液压回路系统的不足,设计分析了一种将双联泵代替定量泵的新型液压回路系统。首先,介绍了双联泵工作的基本原理;然后以不同泵控液压回路系统为研究对象,分析对比了传统液压回路单个定量泵和新型液压回路双联泵在速度、功率、压力等特性的不同之处;最后利用AMESim搭建液压回路系统进行仿真,并进行相关实验测试,仿真与测试结果表明:双联泵控液压回路相比传统单个定量泵控回路,其控制效率高、减少功率损失,从而达到高效节能作用。Aiming at the shortage of hydraulic circuit system controlled by traditional quantitative pump,a new type of hydraulic circuit system which replaces double pump with quantitative pump is designed and analyzed.Firstly,the basic principle of double pump operation is introduced,then the difference of speed and power characteristics between single quantitative pump and new hydraulic circuit double pump in traditional hydraulic circuit is analyzed and compared with different pump-controlled hydraulic circuit system.Finally,the hydraulic loop system is used to simulate of the AMESim,and the relevant experimental test,simulation and test results show that the double pump control hydraulic circuit compared with the traditional single quantitative pump control circuit,its control efficiency is high,reduce power loss,so as to achieve high efficiency and energy saving effect.
