北票矿务局台吉煤矿瓦斯泵房供水泵实现了自动化,经过两年运行证明工作可靠。保证了真空泵的安全运转,为我矿瓦斯抽放工作创造了安全条件。泵房内设两台 SZ—4型真空泵,一台使用一台备用。单台泵小时耗水量为6米~3,室内设静压水箱一个,容积为1.5米~3,每20分钟开动一次供水泵。瓦斯抽出浓度为9%左右,正是具有爆炸危险范围,一旦真空泵所需密封水断路,泵的转子长时运行会产生高温和火花,由于井下瓦斯处于正压状态, Beijiao Bureau of Mines Taichung coal mine gas pump water pump to achieve automation, after two years of operation proved to be reliable. To ensure the safe operation of the vacuum pump for mine gas drainage work to create a safety condition. Pump room equipped with two SZ-4-type vacuum pump, one to use a spare. Single pump hourly water consumption of 6 meters to 3, the indoor set of a hydrostatic tank, a volume of 1.5 m ~ 3, start the pump every 20 minutes. Gas extraction concentration of about 9%, it is with the scope of the explosion danger, once the vacuum pump required sealing water circuit, the pump rotor will produce long-term high temperature and sparks, due to underground gas in a positive pressure state,
