摘要
为了探讨喷头的类型和安装方向对自动喷水灭火系统灭火效果的影响,利用下垂型、直立型和普通型三种工程中常用喷头,分别以向上和向下两种安装方式,在3 m、4 m和5 m的喷水高度下,进行了木垛火的灭火试验。试验结果显示,喷头的类型和安装方向是影响灭火效果的重要因素,喷头的安装方向错误时,其灭火时间会大大增加。
An experiment is done to test the efficacy of an automatic water spray system fixed in different ways.Three types of nozzles are used in this experiment: pendent,upright and general ones,which are fixed upright and downright respectively at three levels at 3,4 and 5 meter high. The result shows that the ways of the nozzles are fixed are crucial in extinguishing a fire with different lengths of fire extinguishing time.
