掘进机内喷雾密闭壳体密封自动补偿装置的研制与应用

Spraying Closeness Housing in Driving Machine Seal up Voluntarily Compensation Installation Develop and Apply

介绍一种掘进机内喷雾进水密封系统,分析了它的工作原理、结构以及关键技术,其特征是密封材料使用高水基密封填料,两端带有环形油缸进行压力补偿,解决现掘进机使用内喷系统承受压力小、易磨损导致泄漏的问题,同时介绍了使用新型密封后掘进机内喷雾达到的效果。

Introduce a kind of spraying in driving machine into water sealed system , analyse its working principle, structure as well as crucial technology, the feature is to seal up material to use high water base sealed packing, two end is had annular oil cylinder carries out pressure compensation, solution shows driving machine to spray system in use to bear pressure little, easy wear is caused the problem leaked , at the same time, introduce the effect of using the new spraying in sealed rear driving machine to reach.
