摘要
主要介绍了射流泵自动注胶装置应用于煤矿防灭火的技术,该装置主要利用了射流泵在汽蚀工况下流量比恒定的特性,保证了注胶的准确配比要求,而且结构简单,操作方便,可很好地满足煤矿防灭火要求。通过试验找出了影响装置流量比和效率的主要因素,从而指出了装置的设计原则,并分析了装置的优缺点。在姚桥煤矿对该装置进行了现场试验,获得了成功。
This paper introduces the technique using the device of auto-slurry-injection jet pump to control fire in coal mine. This device uses thejet pump characteristics of constant flow ratio in cavitations to ensure the exact ratio of slurry-injection. In addition, it has simple structure and convenient operation, so it can commendably satisfy the requirement of fir control and extinguishment in coal mine. The main factors that influence the device flow ratio and efficiency are found out in experiments, thus the design principle is pointed out. The advantages and disadvantages of this device are analyzed. It has been tested in Yaoqiao mine, and the result is good.
