摘　　要：该文通过对EBZ-160掘进机内喷雾系统结构和存在的问题的分析,提出了改进的措施:将水路系统改在悬臂段外侧,安装了固定轴套和旋转轴套,避免了静压水进入悬臂段内的问题。通过水路改造,保证了掘进机内喷雾系统的使用效果,对于避免电机进水、冷却截齿和改善工作面环境有着非常明显的作用。This paper through the analysis of internal spraying system structure and existing problems of EBZ- 160 heading machine, the improvement measures are put forward： to change water system on the outer side of the cantilever, installed the fixed shaft sleeve and a rotating shaft sleeve, avoid static pressure of water entering the cantilever, the modification of the waterway ensured the effect of the internal spraying system in the driving machine, which have the obvious effect avoiding water into the motor, cooling cutting pick and improving the heading environment.
