Hydraulic water well truck rock drill impact reciprocating piston in the high-frequency, high-speed conditions, the seal is not good, not only will cause a sharp drop in impact energy, will lead to serious machine does not work. YYG50 hydraulic rock drill for shock piston high-pressure, high-frequency, strong impact exercise, three-stage seal that gap - Low-back tank - in the form of seals, through the gap throttling high pressure into a low pressure, a small amount of oil leakage by low pressure back tank to flow away, so that the sealing of the third paragraph of the pressure on the low pressure return oil tank pressure, good sealing effect. Hydraulic boring machine rotating mechanism: the reliability of the rotating mechanism is a key factor to guarantee the drilling machine working properly, slewing mechanism fails to turn brazing cause fatigue, torque down, the speed is reduced, perforated prone to jamming phenomenon, loss of drilling machine ability to work. In order to improve the reliability of the rotating mechanism, The YYG50 drilling machine-independent rotary slewing mechanism, driven directly by a CS-100 cycloid motor jumbo rod rotation, the structure is simple and reliable. Hydraulic rock drill Problems: low reliability of hydraulic rock drill impact mechanism, from the underground industrial test, YYG50 hydraulic rock drill impact mechanism reliability is not high, mainly caused by the following two reasons. 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.
