the sealing effect with the size of the gap, pressure difference between the mating surfaces of the length, diameter, size and boring machine processing quality factors, in order to achieve the desired sealing effect, in addition to the rational design of the gap, a good grasp of the clearance of the manufacturing quality in design may be appropriate to increase the length of the mating surfaces with the mating surfaces of the valve spool or the rear of the cylinder can also open several equidistant pressure trough, uniform seal gap, reducing Leakage flow, improve the sealing performance. Since the gap for sealing inevitably leak exists, but after long-term work, wear and tear causes the gap to increase the sealing performance is reduced, it is possible to consider in the case of the structure size to allow the seal into contact seal, i.e. between the mating face additional a wear-resistant, high temperature and a small frictional resistance of the sealing element, in order to ensure the sealing effect. Rock drill impact mechanism work properly critical impact concentricity between the piston and the cylinder, the KG seires hydraulic rock jumbo its concentricity relies entirely on the size to ensure that the adjustment of the three join a long screw tightening torque, making it difficult to achieve the assembly requirements, caused by the difficulty of maintenance and assembly, reduces the reliability of the drilling machine. Proposed three long screws into the four screw connection improved design to ensure uniform tightening, while in the water well truck cylinderbefore and after the creation of the positioning pin, the impact of the piston and cylinder coaxial with the connection long screw tightening torque change, for not only did not change the characteristics of compact structure of the rock drill, but also to maintain the same firm in all directions, to improve the reliability of rock drill, reduce assembly requirements, to reduce the maintenance workload.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,Diesel Movable Screw Air Compressor and so on.
