通过对矿井大型水泵的真空引水启动过程调查研究,针对启动过程中存在的真空度波动和泄漏引起的误启,采用在单台水泵真空电动阀和水泵抽真空管路出口之间增设抽真空出水缓冲环节和液位检测系统,使引水管路中气泡的含量降低。通过液位检测信号有效控制真空系统启停和水泵的启动,提高了水泵启动的可靠性和运行效率,降低了真空引水系统的能耗,延长了抽真空系统和水泵的使用寿命。 Through the research on the start-up process of the vacuum water diversion in the large-scale mine pump, aiming at the vacuum degree fluctuation and the misoperation caused by the leakage in the start-up process, a vacuum pump is added between the single pump vacuum electric valve and the outlet of the pump vacuum pump Links and liquid level detection system to reduce the air bubbles in the water pipe. The liquid level detection signal can effectively control the starting and stopping of the vacuum system and the start of the water pump, which improves the reliability and operation efficiency of the water pump start, reduces the energy consumption of the vacuum water diversion system and prolongs the service life of the vacuum system and the water pump.
