Drilling vehicle classification and role Rock Drill Pneumatic Rock Drill from R & D by the Shandong University of Science and Technology, hydraulic crawler drill price is mainly used for the excavation, rock breaking, rock drilling. Pneumatic Rock Drill, Pneumatic Surface Drilling Rig Drilling Tools system, crawler drill car and hydraulic power station consists of four parts. Gas-liquid linkage drilling machine uses compressed air as the impact of power, hydraulic rotary power to co-driven rock drill conducted drilling, structural main advantage there: 鈶� The pneumatic impact mechanism institutions a simple, reliable work; 鈶� The hydraulic motor volume is small, blast hole driller the power, in the large rotation - impact rock breaking torque conditions, so keep the speed advantages of hydraulic rock drill rig; 鈶� impact mechaborehole drilling rigsnism does not require hydraulic powered, with respect to the hydraulic rock drill, which greatly simplifies the hydraulic power system, greatly reduce overall cost, to further improve the reliability of the machine for easy on-site maintenance. Pneumatic rock drill large thrust and torque conditions under rotation - impact methods, methods of rock breaking, in addition to the impact crusher, truck mounted water well drilling rig applied a strong crushed rock, its energy utilization and drilling speed is much higher than the general impact - rotary rock drill, close to the hydraulic rock drill rig drilling speed. The same time, due to a large thrust, drilling in a compressed state most of the time, to reduce or eliminate solder with tensile stress, avoid the symmetrical stress cycle, from the point of view of the fatigue damage, which will help to improve the brazing with life. Pneumatic Surface Drilling drills, hydraulic drill rig sale, impact power, hydraulic pressure gas as the rotation of power, concentrated long
