With the continuous development and progress of intelligent unmanned mining technology in coal mines, more and more intelligent unmanned fully-mechanized mining faces with large mining heights and super mining heights have been built and put into production, and high-efficiency intelligent fully-mechanized mining technology and equipment have achieved a leap forward development, which also puts forward new challenges and requirements for the liquid supply capacity of intelligent liquid supply system in coal mines.In order to meet the liquid supply demand of intelligent unmanned fully mechanized mining face with super high mining height, the problems of emulsion pump under the complicated working condition of super large flow were analyzed and summarized, and the key technologies to improve the reliability of super large flow emulsion pump station were studied.A new type of shaft system based on herringbone gear pair input shaft and crankshaft is designed, which solves the problem of low stability of gear pair transmission system in megawatt pump station system. The reliability analysis of the reciprocating cross-liner friction pair and the key bearings of the megawatt transmission system is carried out to improve the reliability of the transmission pair. Through dynamic characteristic analysis of valve, visualization technology and high reliability sealing technology research, the performance of high-efficiency cavitation valve is improved. A cavitation suppression method and structure based on permanent magnet intrinsic safety electromagnet and air pocket enrolling are studied to improve the response characteristics of the pilot stage and the anti-cavitation characteristics of the unloading valve port, thus improving the reliability of the high-pressure large-flow unloading valve. The safety and availability of high pressure and large flow pumping stations have been improved through the innovative development of the intelligent early warning and diagnosis system of cloud edge end cooperation.
