基于Logo和变频技术的医院恒压供水设计

Energy Conservation Design of the Constant Pressure Water Supply of Hospital Based on Logo and Frequency Conversion

采用德国西门子逻辑模块Logo和日本三垦SHF、SPF系列变频器及独特最新技术SWS实现高性能全自动恒压供水,根据管网瞬间压力的变化,自动调节某台电机的转速和多台电机的投入及退出,从而使管网出口端保持在恒定的压力值,整个系统始终保持在高效节能和最佳运行状态。

Using Simens logic module Logo of Germany and Sanken SHF and SPF series frequency conversion controller of Japan and unique newest technical SWS, the high performance completely automatic constant pressure water supply is realized. According to pipe network instantaneous pressure change, automatic control some electric motor＇s rotational speed, many electric motor＇s operation and withdrawal, the water supply system can lead the pipe network to keep the constant value of pressure. The overall system can operate at the highly effective energy conservation and the best running status.
