摘要
通过对EBZ-160HN掘进机截割部密封系统进行多次测试改装,将原有的磨擦密封改成旋转密封,并将浮动油封盖进行重新设计,形成双密封,彻底地根治了掘进机爬窝这个故障。避免了每月频繁更换磨擦油封、还因主轴缺油更换主轴等大件的现象,保证了生产掘进进度,起到了节约资金,再创经济效益作用,具有很好的推广使用价值。
By several tested modifications of the sealing system of cutting unit of EBZ-160HN entry-driving machine, the original friction seal was changed into rotary seal, and the floating oil seal cover was redesigned to form double seal, which has completely solved the halt failure of entry-driving machine. It has avoided the frequent replacement of friction oil seal monthly and the replacement of chief axis and other large parts for the oil starvation of chief axis, ensured the tunneling progress, played the role of saving funds and creating greater economic benefits, so it is of good value for promotion.
