从事地下开采的矿山企业,井下的排供水在生产中起很重要的作用。另外,废水回收也有利于节约水资源,降低排供水能耗。为了使排供水工作的正常进行和做好废水回收,较好的办法是实现水泵的自动控制。水泵的运行过程是:排除空气、轻载启动、正常运行和轻载停车等。我矿初步摸索出了一个简单而有效的水泵自动控制系统,如图所示。 Mining companies engaged in underground mining, underground water supply and drainage in the production plays a very important role. In addition, the recovery of waste water is also conducive to saving water resources and reducing the energy consumption of water supply and drainage. In order to make the normal work of the row of water supply and waste water recycling, the better way is to achieve automatic pump control. Pump operation process is: exclude air, light load start, normal operation and light load parking. My mine initially explored a simple and effective automatic pump control system, as shown.
