摘　　要：自动喷水灭火系统以其灭火效率高,经济实用等优点,被广泛应用于各类建筑的消防设计中。以某高层综合楼的自动喷水灭火系统设计为例,分析了该系统各组成部分的设置情况,采用海登-威廉式计算管道水头损失,重点对其水泵的扬程和流量进行计算分析与校核。通过计算校核可知,该建筑的自动喷水灭火系统的设计符合相关规范的要求。在水力计算中,海登-威廉式不仅可以满足一般水头损失计算的要求,用该式计算旧管道的结果也是可信的。此结论为自动喷水灭火系统设计分析与计算校核提供参考。Because of its high efficiency of fire extinguishing , economy and practicality, the automatic sprinkler system is widely used in fire protection designs of many kinds of buildings. In this paper, the sprinkler system of a high-rise building was chosen as the research object. The settings of the components in the system were analyzed The head loss was calculated by Hazen-Williams＇ formula, and the lift and the flow of the pump were especially analyzed by using quantitative calculation. The design of this system conformed to the technical codes. And the Hazen-Williams＇ formula can not only meet the requirements of the common head loss calculation, but also can be applied to the calculation of aging pipes. The conclusion can provide a reference for the analysis and calculation of sprinkler systems.
