The by underground industrial test, Reference YYG50 hydraulic rock drill design is reasonable, compared with the existingdomestic boring machine, its small size, moderate weight and other characteristics more suitable for matching domestic drilling machines, drills, boring mechanical. In the future design, need to be further from the structural problems in the industrial test to be improved to improve its reliability, you can get a wide application.YYGJ90 hydraulic rock drill dynamic performance, the dynamic performance of YYGJ90 hydraulic rock drill impact institutions of computer simulation analysis study achieved satisfied with the results well consistent with the general theory of analysis and measured results, and explore out of the hydraulic rock drill impact of institutional dynamic movement mechanism of some new rules and characters. The research work completed, led the authors to draw some of the more academic reference value conclusion, to improve the design and structure of this rock drill and similar models provide more reference theoretical basis. YYGJ90 send pressure drilling machine is a slide valve control system front chamber of constant pressure hydraulic rock drill, YYGJ90 hydraulic rock drill impact mechanism established three different degree of sophistication of the power bond graph model. Modeling, give full consideration to the system ministries hydraulic fluid capacitance effect of the cavity (ie the compressibility of the hydraulic oil in the cavity and possible compression of the pipe wall the expansion characteristics) and the bus characteristics of the cavity along the way and local pressure loss characteristics of the form of a liquid barrier (linear or nonlinear) to be described; the same time, also be taken into consideration and the description of the inertial characteristics of the impact of the hydraulic cylinder piston and the control spool valve body, in addition, also included in the model two piston and the valve body by the Coulomb friction force moving parts, spool valve port cover the amount of factors.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.
