摘　　要：比例控制技术在液压系统中的应用越来越广泛,比例方向阀调节执行元件速度时,与压力补偿器配合使用,其优点可使比例阀阀口压差基本保持不变,从而使执行元件的速度不受负载变化的影响。目前,压力补偿器已广泛应用于冶金、电力、建筑、煤矿机械等各个行业。Proportional control technic has been abroad used in hydraulic system, proportional directional valve need to be cooperated with pressure compensator in order to adjust the speed of actuator, the excellence is that the pressure difference of valve port do not change, the load change can not impact the speed of actuator. At present, pressure compensator has been abroad used in metallurgy, electric, construction and mining machine.
