本文首先提出“矿井排水设备吨水百米电耗特性”表达吨百电耗随工况而变的规律,论证了矿井常用水泵的吨百电耗定性特性具有随流量加大而降低的特征,指出泵效率最高工况不是吨百电耗最低工况,提出了降低吨百电耗的途径,列举了各种措施的节电效果。 This paper firstly put forward the law that the power consumption of one hundred meters per ton with the working condition changes when the power consumption of one hundred meters per ton of water drained by a mine drains shows that the qualitative characteristic of one hundred percent of power consumption of the common pump in a mine has the characteristics of decreasing with the increase of the flow, It is pointed out that the highest pump efficiency is not the lowest power consumption per ton of power, and the way to reduce the power consumption per tonne is proposed. The power saving effects of various measures are listed.
