综采工作面智能供液系统设计和应用

Design and Application of Intelligent Solution Supply System at Fully-mechanized Working Face

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 high pressure fluctuation in the exit of emulsion pump station and redundant and inaccurate artificial solution preparation at 13091 working face in Yuecheng Colliery,the author develops an intelligent solution supply control system and makes a field test on its automatic solution preparation,constant-pressure solution supply and intelligent control,whose testing results show it can keep the operation stress maintain,realize the automatic oil absorption and intelligent emulsion proportioning with 3.9%concentration and ensure the intelligent operation of emulsion pump station.
