南阳棉纺织厂每月取水量平均55万吨,付水资源费25万元左右,深井年耗电230kWh,电费70万元。因生产生活用水管网系统没分开,低谷时深井泵也必须照常运行。使用变频调速恒压供水系统,可以随时调节水压,低谷用水时自动降压,水泵电机随压力变化改变频率,既节水又节电。根据对宜昌等应用单位的实际考
Nanyang Cotton Textile Factory takes an average of 550,000 tons of water per month, pays about 250,000 yuan for water resources, and uses 230kWh of electricity for deep wells and 700,000 yuan for electricity. Because the production and domestic water pipe network system is not separated, the deep well pump must also operate as usual at the time of trough. The use of variable frequency constant pressure water supply system, you can adjust the water pressure at any time, when the valley water automatically depressurized, water pump motor changes with frequency changes in frequency, not only saving water and saving electricity. According to the actual test of the application units such as Yichang
