综采工作面智能供液系统关键技术研究

Key Technology Research and System Application of Intelligent Liquid Supply System

针对岳城矿13091工作面乳化泵站出口压力脉动大、人工配液繁琐且准确度低等缺点,开发了一套乳化液泵智能供液控制系统,并对其自动配液、恒压供液及智能化控制等功能进行了现场试验。试验结果表明,乳化液泵工作压力保持在30.2~31.5 MPa,能够实现自动吸油和乳化液智能配比,乳化液浓度为3.9%左右,系统运行状况良好,实现了乳化液泵站的智能化运行。

Aiming at the disadvantages of large pressure pulsation at the outlet of emulsion pump station in the 13091 working face of Yuecheng Coal Mine,complicated manual liquid mixing and low accuracy,a set of intelligent liquid supply control system for emulsion pump was developed,and its functions of automatic liquid mixing,constant pressure liquid supply and intelligent control were tested on site.The experimental results show that the working pressure of the emulsion pump is maintained at 30.2-31.5MPa,which can realize the automatic oil absorption and the intelligent mixing of emulsion.The emulsion concentration is about 3.9%.The system is in good condition,and the intelligent operation of the emulsion pump station is realized.
