摘　　要：基于国家标准的传统自吸式泡沫枪,设计了不同尺寸的泡沫枪喷嘴,并从泡沫枪喷嘴直径尺寸、泡沫的接收距离等角度分析水成膜泡沫灭火剂的发泡倍数以及25%析液时间的变化规律。实验结果表明,在一定范围内,随着泡沫枪管径的增加,发泡倍数和25%析液时间均呈现出先增加后趋于稳定的规律;在一定距离范围内接收泡沫时,随着接收距离的增加,发泡倍数与25%析液时间呈现变大的趋势,但变化幅度不是很大。Different size of foam nozzles was designed,based on the conventional self-priming foam nozzle required by the national standard.The characteristics of the expansion and 25%drainage time were obtained,under the factors of nozzle diameter and the distance between foam receiving places and the nozzle.The results showed that the expansion and 25%drainage time both rise afterwards become steady with the increasing of nozzle diameter;the expansion and the 25%drainage time also raise as the increasing of the distance,but the change is not obvious.

关 键 词：泡沫枪 发泡倍数 析液时间 喷嘴尺寸
