闭环变频控制技术在煤矿主排水中的应用

Application of Loop Frequency Control Technology in Main Water Drainage in Mines

以矿用本安型工业控制计算机和多功能控制驱动器结合系统为例,介绍了变闭环控制在煤矿主排水中的应用。控制系统可按主水仓液位等进行自动调节主排水泵的转速和开启台数,还可根据运行时间自动倒机切换运行和避峰填谷运行,实现设备的低碳、高效、高可靠性的运行效果,有效保证煤矿生产的安全运行。

Taking the combined system of intrinsic safety type industrial control computer and muhifunction control driver as an example, the paper introduced the application of varied closed-loop control in the main water drainage in mines. The system could automatically control rotating speed and number of main discharge pumps to achieve closed-loop In addition, the system could achieve the automatic on the running time to realized the low-carbon, effi guarantee the safety production of mines. the basis of the liquid level of main water warehouse hing operation and peak load shafting operation based and reliable operation, which could effectively
