摘　　要：阐述了电液先导控制阀组的控制原理和结构特点,介绍了先导阀组的试验原理和步骤。在不同压力、流量等多种条件下对先导阀组静动态特性进行了试验研究,得到了其动态特性曲线及静态特性曲线,得出了相应的结论。The control concepts and configuration characteristic are detailed, as well the experiment principle and process of the pilot valves are introduced. Under certain conditions of different pressures and discharges the experiment research is done to the pilot valves on the dynamic characteristic and the static characteristic. The dynamic and static characteristic curves are also obtained. Then, relevant conclusion is drawed.
