摘　　要：通过对DA阀的控制原理进行系统分析,论证了其利用DA阀的自动调节作用,可以始终保持液压泵扭矩与发动机的输出扭矩的最佳匹配,防止了机械系统发动机因负载过大而熄火,并提高了使用效率,同时也减轻操作者的心理负担。DA阀在机械行业必将得到越来越广泛应用。Through a systematic analysis of the control system of DA valve,the paper proves the automatic adjusting function of DA valve,which can always keep the optimal match between the hydraulic pump torque and the output torque of engine,avoid the flameout of the mechanical system engine due to the heavy load,improve the use rate and at the same time relieve the operator s psychological load.DA valve will be used in the mechanical field widely.
