Analysis on electrohydraulic speed servo control schemes for anti-explosion hydraulic hoisters
Abstract：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.
