Current status of application and development trend of mining high-pressure and large-flow-rate emulsion pump station

Based on the understanding of the main technical difficult for high-pressure and large-flow-rate mining emulsion pump station,the technical characteristics and research outcomes of several typical domestic and foreign high-pressure and large-flow-rate emulsion pump station were presented,in terms of pump system configura tion,the level of pressure and flow rate ,the control pattern,the pressure control pattern and structural features. The technology gap between domestic and foreign high-pres sure and large-flow-rate emulsion pump station was summarized. Finally,the technology trends of the high-pressure and large-flow-rate emulsion pump station were also pr. edicted.The inevitable developing trend was that the emulsion pump station combined with the control system using frequency control in conjunction with the electro-hydra ulic unloading technic and the on-line intelligent diagnostic capabilities based on the high-precision sensors.
