摘　　要：采煤机自适应调高对煤炭开采的自动化和高效率有着重要的影响,该文将压力补偿阀应用在采煤机液压调高系统上,油缸的流量不受负载的影响而只取决于阀口的开度,该方法解决了因负载变化引起的流量的不确定性问题,使得滚筒的自适应调高的控制精度更高。Shearer self-adaptive adjusting high has an important effect on coal mining automation and high efficiency, this paper will pressure compensation valve used in coal mining machine hydraulic height adjusting system, cylinder flow is not affected by load but its opening only depends on the valve port, the method solves the problem caused by change of load flow uncertainty the problem of the drum, the precision of adaptive control of high is more higher than before.

关 键 词：采煤机 压力补偿 自适应调高 负载敏感
