通过深入小煤矿和到井下水泵房深入调查,分析发现有底阀排水系统存在诸多问题,可以利用现有的设备添加一些附件和改进现有水泵控制电路,使水泵实现无底阀自动化排水,从而实现泵房无人值班看守运转。这样,既能节约能源消耗,又能提高小煤矿企业的经济效益。 Through in-depth investigation of small coal mines and downhole pump houses, it was found that there are many problems in the bottom valve drainage system. Some existing accessories can be added and existing pump control circuits can be added to make the pump realize automatic drainage without bottom valves. Achieve pump room unattended guard operation. In this way, both to save energy consumption, but also improve the economic efficiency of small coal mines.
