煤矿掘进机机载内喷雾装置是掘进机掘进生产的必备部件,在巷道掘进中能够有效地捕尘、降尘,对煤矿工人的健康和巷道掘进生产安全具有重要作用。1工作原理巷道内的水经过高压水泵升压后,通过截割头上的喷嘴以雾状形式喷出,在巷道内形成一堵水墙,阻隔粉尘向后扩散,并在掘进面处捕捉粉尘。但传统内喷雾装置存在压力偏低、水密封易损坏和更换工作
Coal mine boring machine airborne spray device is an essential part of roadheader driving production, in the roadway tunneling can effectively capture dust, dust, coal miners health and roadway tunneling production safety plays an important role. 1 Working principle The water in the roadway is pressurized by the high-pressure water pump and then sprayed through the nozzle on the cutting head in the form of mist to form a water wall in the roadway to prevent the dust from diffusing backward and catch the dust at the driving face . But the traditional spray device is low pressure, water seal is easy to damage and replacement work
