发布时间：2018-09-19 14:08
【摘要】：通过对短壁采煤机调高系统进行理论分析,找到了摇臂空载下降过程中发生抖动的原因。提出的新型平衡阀组解决了双向摆动的摇臂下降时抖动和上升时附加阻力的问题,显著提高了短壁采煤机调高系统的稳定性。
[Abstract]:Based on the theoretical analysis of the height adjustment system of short wall shearer, the causes of the jitter in the falling process of rocker arm without load are found out. The new balance valve set solves the problems of dithering when the rocker arm drops and the additional resistance when rising, and improves the stability of the height adjustment system of short-wall shearer.
