分析了 MG2× 30 0 - W采煤机存在的主要问题及产生问题的主要原因 ,重点分析了采煤机牵引部位热交换系统的缺陷 ,提出了采煤机牵引部位冷却系统的改进措施 ,提高了采煤机的牵引能力 ,使采煤机满足了下分层条件下综采生产的需要
The main problems existing in the MG2 × 30 0 - W shearer and the main causes of the problems are analyzed. The defects of the heat exchange system in the traction part of the shearer are analyzed emphatically. The improvement measures of the cooling system at the traction part of the shearer are put forward Shearer’s traction capacity, so that shearer to meet the requirements of the next stratified production of fully mechanized production
