随着我国煤炭工业的高速度发展,综合机械化采煤越来越普遍。但由于滚筒的高速切割,煤尘的发生量很大,对采煤司机及支架操作工的健康和安全生产,都有很大的影响。如何解决综采工作面的灭尘问题,已成当务之急。 滚筒式采煤机采用喷雾降尘是比较经济而有效的方法之一。喷雾降尘,首先要有压力水供应,再通过喷雾器,把水变成所需要的雾状,以达到灭尘的目的。由于采煤机喷雾各项参数的要求,压力水要有一定的压力范围;同时,采煤机在工作中,需要随时开停供水阀门,要求供应的压力水,有一个控
With the rapid development of China’s coal industry, comprehensive mechanized mining is more and more common. However, due to the high-speed cutting of the drum, the occurrence of coal dust is very large and has a great impact on the health and safety of coal mine drivers and stents operators. How to solve the dust problem of fully mechanized mining face has become a top priority. Drum shearer using spray dust is more economical and effective method. Spray dust, first of all have pressure water supply, and then through the sprayer, the water into the required mist, in order to achieve the purpose of dust. Due to the requirements of various parameters of shearer spray, the pressure of water to have a certain pressure range; the same time, shearer at work, need to open and close the water supply valve at any time, the pressure of water supply requirements, there is a control
