消防给水系统剩余水头的计算

CALCULATION OF SURPLUS WATER HEAD OF THE FIRE WATER SUPPLY SYSTEM

室内消防给水有两种主要工况:水箱供水和水泵供水。它们形成的剩余水头是不相同的。本文从水力学能量方程式着手,推导出剩余水头的计算公式,明确了一些概念,并对在工程设计中的具体应用提出了建议。

Fire water supply system in buildings generally fails into two types:the water tank type and the water pump type,and the water surplus heads of the two are different from each other.Beginning with hydraulic energy equations,this paper presents the calculation formula of surplus water head,clarifies some concepts and gives some suggestions on the application of the formula.
