The function of wind-water linkage drilling wind

The function of wind-water linkage drilling air: a device that can reduce the nozzle strength and play the role of fire prevention and dust reduction, which can realize automatic water distribution when drilling and automatically stop water distribution when drilling stops. Water distribution is controllable and can be adjusted according to the water content of coal seam. During drilling construction, a small amount of water is automatically added into the compressed air pipeline to form water mist, so that the water mist is evenly mixed with the ejected coal to form a reasonable proportion of coal slag, which ensures the smooth drilling, reduces the dust concentration, improves the working environment, improves the cooling effect of the drilling tool, reduces the high-temperature wear of the drill bit, and reduces the risk of hole burning or fire in the hole. The device is suitable for compressed air slag discharge, compressed air and mechanical mixed slag discharge drilling.
