一、泡沫的救活机理
1. The mechanism of foam saving
泡沫的相对密度小,流动性好,持久性和抗烧性强,导热性低,粘着力大。这些物理性能使它能迅速覆盖在焚烧液面上,可阻隔可燃蒸汽 、空气、热量的传递,加上冷却效果,起到了救活的效果。
The relative density of the foam is small, the fluidity is good, the durability and the burning resistance are strong, the thermal conductivity is low, and the adhesive force is great. These physical properties enable it to be quickly covered on the surface of incineration, which can obstruct the transmission of flammable steam, air and heat, plus the cooling effect, which has played an important role in saving lives.
二、泡沫消防车的结构及作业原理
Two. The structure and operation principle of the foam fire engine
泡沫消防车由汽车底盘和其上装部分的专用设备组成。国内外出产的泡沫消防车多选用整车出产厂家供给的二类通用汽车底盘。其专用装 置首要包含取力器、水泡沫液罐、器件箱、泵房、消防泵、真空泵、泡沫份额混合设备等。
The foam fire engine consists of the chassis of the car and the special equipment in the upper part of the car. The foam fire-fighting vehicles produced at home and abroad are mostly used for the two types of general vehicle chassis supplied by the whole vehicle manufacturers. Its special device mainly includes the force collector, water foam tank, device box, pump room, fire pump, vacuum pump, foam share mixing equipment, etc.
其作业原理是:经过取力器设备将汽车底盘发 动机的动力输出,并经一套传动设备驱动消防泵作业,经过消防泵、泡沫份额混合设备将水和泡沫按必定比例混合,再经消防炮和泡沫救活枪 喷出救活。

Its working principle is: after the equipment power take-off power output of the automobile chassis engine, and by a gear drive device of fire pump, fire pump, after the foam mixing equipment will share the water and foam are mixed according to a certain percentage, and then by the gun fire and foam gun spray to save living life.
因而,要求汽车底盘有必要满意必定的载质量和发动机功率。现在已制订了国家标准,底盘选用依据《消防车通用底盘系列、型式、基本参数和技能要求》的国家标准选用,依据职业标准《泡沫消防车通用技能条件》附录A的要求选用发动机的功率有必要满意其规则要求。
Therefore, it is necessary for the vehicle chassis to be satisfied with the certain load and engine power. It has developed a national standard, "fire truck chassis selection based on general chassis series, types, basic parameters and technical requirements of the" national standards for selection, according to occupation standard "foamengine general skills" conditions of annex A requirements of the power of the engine is necessary with its rules.
1、动力输出设备
1. Power output equipment
国产泡沫消防车多选用主车发动机取力方法,取力器安置方法可有多种方式,而现在中重型泡沫消防车多选用将取力器置于主离合器和变 速器之间的夹心式取力器(变速器前置式)和传动轴取力(变速器后置式)两种方式。选用夹心式取力器将主发动机的动力取出经传动系统传 到水泵,驱动水泵工作,能够实现双动功能。现在大多选用此种方式。

Most of them are used in this way now.
2、水-泡沫罐体
2, water foam tank
水-泡沫罐体是泡沫消防车上装载救活剂的首要容器,依据消防职业的发展可选用多种资料制做,上世纪八九十年代多选用聚酯玻璃钢资料,现在逐渐发展到选用优质碳钢资料及不锈钢资料制造。
Water - foam tank is the primary container save agent loading foam fire truck, according to the development of fire occupation can choose a variety of data produced, in 80s and 90s the last century using polyester FRP materials, now gradually developed into high-quality carbon steel and stainless steel material manufacturing.
