变频恒压供水设备在大型泵站的应用

针对传统技术供水方式存在的问题．介绍了利用变频调速技术调节水压的原理、变频供水设备的选用；提出了新沐河大浦抽水站变频供水设备在运行中出现的问题及解决方法。结果表明，大型泵站采用变频恒压供水系统，对确保水压平稳、实现泵站全自动控制有着十分重要的意义。

Application of variable Frequency Constant Pressure Water Supply Equipment in Lage-scale Pumping Station

According to the problem existing in the traditional technological water-supply, principle of applying variable frequency timing technology to adjust water pressure and selection of water-supply equipment with variable frequency are introduced. Problem existing in water-supply with variable frequency in Xinmu river Dapu pumping station and resolution are put forward. Results show that it is very important to adopt variable frequency and constant pressure to ensure steady water pressure and to realize auto-control in pumping station.
