二次加压给水中一些问题的探讨

A Discussion of Some questions in Secondary Water-supply System

生活二次加压给水中存在着很大的能量浪费。本文对典型的给水方式进行分析 ,以实际例子展示水泵选型、管材、管径等因素对能量利用率的影响程度 ,最后探讨决定能量利用率的几个因素 。

A large energy is consumed during secondary water-supply. This paper analyze on the typical water-supply mode. By using the practically examples to show the influence lever of energy efficiency caused by diathesis of pump type, tube material and tube diameter. In conclusion to probe into the method of increasing efficiency.
