针对综放工作面移架、放煤时,产生粉尘量大以及原来的支架间喷雾系统存在启动慢、控制不灵活、降尘力度不够等特点,利用可编程序控制器取代分立元件,电子控制降尘喷雾系统,实现了控制方式可调、开启灵活、操作方便、安全可靠的智能化控制。 In view of the characteristics such as slow moving, uncontrollable spraying, inadequate dust reduction and so on, when using the fully mechanized caving face to move the frame and release the coal, the amount of dust generated is large and the original spray system between supports is slow to start. The programmable controller replaces the discrete components and electronically controls dustfall Spray system to achieve an adjustable control mode, open flexible, easy to operate, safe and reliable intelligent control.
