合理调节排水系统的流量提高系统运行效率

Regulate the flow of drainage system reasonable to increase the operation efficency of the system

排水系统的流量决定了系统是否处于经济运行状态。多年来煤矿对流量的调节有不同的方法 ,对改变管网阻力调解工况 ,改变水泵特性调节工况 ,改变水泵转速调节流量几种方法进行了总结归纳 。

The flow of the system for drainage pump determinates the cconomic operation statement of the system.There are a few ways of flow regulation have been used for many years.The paper summarizes the adjusting working condition methods about changing the pipe net resistance,changing pump character and changing pump running speed,and introduces the economic regulation ways.
