变频技术在老式矿井主排水系统技改中的应用

The Application of Frequency Conversion Technique on the Main Drainning System of Old Coal Pit

针对目前老式矿井水平延伸主排泵技改方案中,大功率电动机的节能问题进行探讨,重点对变频调速进行分析,证明变频调速可节支降耗,带来可观的经济效益。

It is approached to save high-power motor's energy in the technique reconstruction program of main draining oriented horizontal elongation of old coal pit in this paper. It analyses frequency conversion velocity modulation mainly. It is proved that using frequency conversion velocity modulation can save fund and produces appreciable economic effect.
