摘　　要：通过对普通型双向液力锁和阻尼型双向液力锁的理论分析,找到了普通型液力锁在采煤机摇臂下降过程中发生抖动和系统压力过高的原因,提出采用阻尼型液力锁可以解决这些问题,并找到了降低摇臂下降压力的途径。The reason that the common type double liquid control one-way valve is shaking and the system pressure is rising too high during the shearer rocker arm down process is analyzed.And the reason why the damping double liquid control one-way valve can solve these problems is presented.The solutions to decrease the pressure during the arm down process are provided.
