The development of the national economy needs a lot of power, and the electric power of our country mainly depends on the strong power generation, coal is the pillar of great power. Nowadays our country coal mining has access to 1000 meters below the surface mining, drilling depth also deepened. Company to build well pattern development developed the input power 160KW constant power hydraulic double liquid grouting pump, the pump maximum flow rate 500L/min, maximum pressure 35Mpa. Double grout ratio can be adjusted arbitrarily, the design of the production process, solved many technical problems, such as the hydraulic system flow and the formation of the hydraulic impact of hydraulic system; hydraulic control contactless commutation; the plunger surface hardening treatment and seal configuration. China"s drilling engineering and mine grouting pump with high power, high pressure pump that has been used in oil field by prying pump, and oil pump transmission medium to small and drilling mud circulation, and the grouting pump transmission medium to cement slurry, small cement slurry to plunger and seal wear more. Moreover the requirements of the casting process of pressure grouting performance mechanical variable oil pump is unable to meet the. I 160KW R & D constant power hydraulic double liquid grouting pump can meet the above requirements. In mine construction and mine pump field, the current leader.
