矿井主要扇风机的耗电量是很大的,在煤矿中,往往占全矿耗电量的30%,个别的可达40~50%。所以管理好和合理使用好现有的扇风机,提高其运行效率,减少电耗,充分挖掘扇风机的潜力,就可以取得重大的经济效果。例如枣庄矿务局陶庄矿东风井的70B_2—21型№24风机经改造后,风机的静压效率比原来的提高13%,每年可节省电耗85万度,节省电费6.8万元。
The main fan fan power consumption is great, in coal mines, often account for 30% of the total power consumption, individual up to 40 to 50%. Therefore, management and good use of the existing fan, improve its operating efficiency, reduce power consumption, fully tap the potential of fan, you can achieve significant economic results. For example, Zaozhuang Mining Bureau Dongzhuang Taozhuang Dong 70B_2-21 type № 24 fan after the transformation, the fan static pressure efficiency than the original increase of 13%, annual savings of 850,000 kWh power consumption, saving electricity 68,000 yuan.
