摘要
随着城市建设的快速发展和人民生活水平的不断提高,对城市供水的质量也提出了更高的要求。采用PLC、组态软件、变频器等组成的全自动恒压供水控制系统,可根据管网压力自动调节供水流量,既保证了管网压力恒定,又达到了节能的良好效果。
With rapid development of city construction and persistent improvement of people＇s living conditions, urban water quality has been set higher requirements. In this paper, the water supply system with constant pressure which is composed by PLC, configuration software and inverter. Adjusts automatically the water flow aceording to the pressure. This can guarantee the constant pressure and energy saving.
