摘　　要：本文分析了电牵引采煤机喷雾系统及液压调高系统的现状及存在的问题 ,针对存在问题 ,对采煤机喷雾与滚筒调高系统进行了综合分析 ,提出调高系统工作介质使用纯水 ,喷雾系统采用高压水射流技术 ,调高系统与喷雾系统共享同一压力源的方案。The paper describes systematically the structure of spraying system and height adjusting system of electric coal cutting machine,analyses the problems of both systems.Against these problems,a new conception has been developed that the height adjusting system uses water as working medium,the spraying system uses the technique of high pressure fluidics and both systems share the same pressure source.
