煤矿排水系统最佳节能模式的变频运行方式探讨

Discussion of the frequency operations of the mine drainage system in the best energy-saving mode

为了满足煤矿排水系统的排水需要和排水设备高效运行的要求,针对煤矿井下涌水量变化大的特点,按照水泵的特性及变频器的节能原理,探讨了煤矿排水系统变频运行的几种节能方式,指出可以通过改变变频运行的方式来实现排水系统的最佳节能。

Satisfying the drainage requires of the coal-mine-drainage system and the high-effective operational demands of drainage devices and against the characters of great changes of the underground water amounts, the paper discusses several energy-saving methods o f the frequency operation for the mine drainage system according to the performance of pumps and the energy-saving principle of converters, and promotes the best energy-saving mode is gotten by changing the methods of frequency operation.
