摘要
以陕西省西安市某建筑工程自动配水灭火系统设计为研究对象,采用图表分析方法对自动喷水灭火系统的喷水系数进行分析,结合工程实例对不同喷水系数条件下的最不利管段水力进行计算。结果表明,无论是在何种建筑场合,采用自动喷水灭火系统的灭火成功率均≥90%;在同一喷头系数条件下,自动喷水灭火系统中节点喷头进口端的工作水压力随着喷头流量的增加而增加;在同一喷头工作压力条件下,自动喷水灭火系统中节点喷头流量与喷头系数呈正比;基于自动喷水灭火系统性能的最不利管段水力计算分析可以对管段和喷头的水力压力、水流量以及总水头损失进行分析。
This paper takes the automatic sprinkler system design of a building project in Xi’an of Shaanxi Province as the research object, analyzes the water spraying coefficient of the automatic sprinkler system by using chart analysis method, and calculates the hydraulic power of the most unfavorable pipe section under different water spraying coefficients. The results show that the fire extinguishing success rate of the automatic sprinkler system is ≥90% in any building, the working water pressure at the inlet of the node sprinkler increases with the increase of the sprinkler flow under the same sprinkler coefficient, and the flow rate of node sprinkler in automatic sprinkler system is proportional to the sprinkler coefficient under the same working pressure of sprinkler. The hydraulic calculation and analysis of the most unfavorable pipe section based on the performance of the automatic sprinkler system can analyze the hydraulic pressure, water flow and total head loss of the pipe section and nozzle.
