| 摘 要： | 为计算船舶感烟探测器的探测时间和布置间距,在现有感烟探测器迟滞现象研究成果基础上,根据临界速度法,建立感烟探测器探测时间计算模型,提出探测器布置间距的近似计算方法.计算结果表明,对于平整顶棚,感烟探测器探测时间随着布置间距的增大呈线性增大,而对于走廊(或下有横梁的顶棚),当探测间距大于走廊宽度时,在规范规定的最大间距范...

| Abstract: | To accurately calculate the response time and arrangement space of smoke detectors in ship,based on the research achievements on lag phenomenon of smoke detectors,a model for calculating the response time of smoke detectors is established and an approximate method for calculating the arrangement space of smoke detectors is proposed.The calculation results show that,for plane ceiling,the response time of smoke detector will increase linearly with the increase of arrangement space;for corridor or confined cei... |
