Work drilling machine is pumping reverse circulation type. Its working principle is: the role of atmospheric pressure, circulating liquid by sedimentation through ring back to the ditch along the bottom of the wellbore flow gap, then the turntable drive drill, drill driven rotary drilling conducted by the mud pump aspiration to establish a negative pressure suction drill mud debris cavity, and then rose to tap into the sedimentation tank through the mud pump, circulating fluid after precipitation continue to flow into the wellbore, again and again, forming a reverse circulation drilling work .

Well drilling machine consists of a piston, the exhaust air cavity under 180 drilling machine picture, down into the drill bit from the cooling effect, and the bottom of the hole cuttings out of the wellhead. Its rotation and circulation flushing part structure and wash well with compressed air rotary turntable rig is basically the same as the drill bit or tungsten carbide teeth cone bit and so on. Pneumatic DTH drilling rig can be used for deep hard rock drilling 180 drilling rig, drilling speed is high, and the drilling speed is not increasing depth due to reduced drilling, borehole drilled relatively straight. 180 drilling machine parts, Prius, Fenxi County 180 drilling machine provided by Luoyang Prius Drilling Equipment Co., Ltd.
