摘　　要：在分析现有液压提升机的液压控制系统的结构与特点的基础上,建立泵控马达电液伺服调速系统,以模拟液压提升机的闭环控制与运行工况,通过对带/不带位置环泵控马达伺服系统的调速特性的分析,指出液压提升机的电液伺服控制应在引入马达转速反馈形成转速闭环的同时,保证变量泵的排量是独立可控的,并以此为据,针对传统液压提升机进行自动化改造,设计了带/不带位置环的防爆液压提升机电液伺服调速系统。Based on the analysis of construction and disadvantages of hydraulic control system existing in hydraulic hoisters,a pump controlled motor speed servo system was set up to simulate the close loop control and process of hydraulic hoisters,and then dynamic performances of the system with/without position loop were analyzed,and a conclusion was gained：the electrohydraulic servo control for hydraulic hoisters should ensure the displacement of a variable displacement pump to be regulated independently while motor＇s rotary speed are fed back and to be controlled in closed loop.Based on this theory,in terms of automatic transformation for traditional anti-explosion hydraulic hoisters,those electrohydraulic speed servo control systems with /without a position loop were designed.
