对自来水厂供水方案选择的分析

Analyse on the Plan Selection of Supply puming Waterworks with Water

本文以普明水厂为例,说明将水泵变速运行以适应用水量的变化又保持恒定的扬程,是最优的一种供水方式。它革除了传统的水塔、水箱、气压罐等容器。因此,投资省、供水质量好,节能效果显著。近年来这一新技术已在水泵站、城市小区、高层建筑、工业及消防用水各领域逐步推广,均获得较好的经济效益。 当用多台泵并联供水时,可将台数控制与转速控制结合在一起,因此可靠性更高,节能效果更好。

Pump motion with variable velocity is an optimum operating mode of water supply , Puming waterworks for example,it can adapt to water quantity change ,keep steady pumping - up height ,and reduce classical water tower ,water tank ,and high pressure tank. When parallel connecting with multi pumps ,pump quantity controll can be combiened with rotating speed regulation ,its reliability is better ,effect of saving energy is better.
