In fact, not only is required for different rock drill three screw tightening torque, even if it is the same rock drill three long screw tightening torque required will also vary with the time change and change. (2) hydraulic rock drill rotating mechanism failure rate is high: the rotating mechanism of the rock drill is a rotary motor, gear, turn solder sleeve and seals and other components, in the industrial test period in addition to the motor output shaft at Yx ring replacement more frequently outside , slewing mechanism of the rest of the maintenance workload is small. Time to replace the seal for 10min, the replacement cycle for about a week, frequent replacement not only affects the normal operation of the underground, to delay the progress of the excavation, but also may be caused by installation errors gear bearing damage. Drilling machine must be in the top tight Rod solder tail to work properly, turn solder sleeve pressed in the thrust plate, its forces, generally drilling and drilling when rock the brazing rod reaction force, resulting in the transfer brazing the friction between the sleeve and the thrust plate, which not only caused serious thrust plate wear, and increased rotation resistance moment, affect the normal work of the rock drill. Hydraulic rock drill improvements: Theimpingement structure of the hydraulic rock drill Improvement, gap sealing due to the sealing of the mating surfaces between the valve body and the rear cylinder with oil, fully rely on a small gap between the surfaces of the two relatively moving parts to achieve a seal.Zhengzhou Dayu Machinery Co., Ltd. is a leading mining machinery supplier in China, Business scope:All Pneumatic Mining Crawler Drilling Rigs,Hydraulic Mining Crawler Mining Drilling Rigs,Integrated Mining Crawler Drilling Rigs,Down Hole Mining Drilling Machine, Crawler Water Well Drilling Rigs,Truck Mounted Water Well Drilling Rigs so on.
