红旗矿区-30米排水系统,是保证我矿正常生产的主要排水设备,又是耗电的重要部位。该系统安装了四台8DA8×4型水泵和先四条后二条管路,自投入使用以来,一直是单台单管运行,系统效率低,排水耗电大。几年前,我们用200D43×4型更换了一台8DA8×4型水泵,收到了一定的节电效果。 1983年初,我们决定对该系统进行改造,目的是有效地提高水泵效率和改善管路特性,降低管路阻力损失,以节省排水用电。采取的主要措施是用
Red flag mining area -30 meters drainage system, is to ensure that mine normal production of the main drainage equipment, but also an important part of the power consumption. The system installed four 8DA8 × 4 type pumps and the first four after the two pipelines, since put into use, has been a single single-tube operation, the system efficiency is low, draining power consumption. A few years ago, we used a 200D43 × 4 type to replace a 8DA8 × 4 type pump, received a certain energy-saving effect. In early 1983, we decided to retrofit the system to effectively improve pump efficiency and improve pipeline characteristics, reduce pipeline resistance losses, and save electricity for drainage. The main measure is to use
