摘要
在分析MGTY400-900-3.3D电牵引采煤机当前主要故障及其原因的基础上,分别对该型号采煤机外牵引润滑系统、外牵引系统以及液压系统提出了整改方案。实践应用表明,改造后的MGTY400-900-3.3D采煤机其维修时间及成本大幅下降,从而使得在节约开采成本的同时也提升了采煤效率。
On the basis of analyzing the main faults and causes of electric traction shearer at present,the rectification schemes of external traction lubrication system,external traction system and hydraulic system of shearer are put forward respectively.The practical application shows that the reformed shearer greatly reduces its maintenance time and cost,and not only saves the mining cost,but also improves the coal mining efficiency.
