泡沫消防车单从字面上了解就能够看出来是用来应对各种火灾的,每天上下班的路上你可能会看到几辆消防车鸣着警笛呼啸而过,你可能也会瞄上两眼,心想消防车不就那么回事嘛!其实不是你想的那样,消防车的内部结构及作业原理是极其复杂的,今日就带着大家一起了解一下泡沫消防车的组成结构及作业原理。
Bubble trucks literally respond to all kinds of fires. You might see a couple of fire trucks whistling by on your way to and from work every day. You might also look at them and think they're not. Actually, it is not what you think, the internal structure and operation principle of the fire engine is extremely complex. Today we will take you to understand the composition and operation principle of the foam fire engine.
一、泡沫的救活机理
First, the mechanism of foam rescue.
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 foam has relatively small relative density, good fluidity, durable and strong burning resistance, low thermal conductivity and large adhesive force. These physical properties enable it to quickly cover the incineration liquid surface, can block the transfer of combustible steam, air, heat, coupled with cooling effect, played a lifesaving effect.

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 truck is made up of the special equipment of the vehicle chassis and its upper part. Domestic and foreign foamed fire trucks often use two types of general vehicle chassis supplied by vehicle manufacturers. The special equipment mainly includes force collector, water foam tank, device box, pump house, 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。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。
Its working principle is: the power of the chassis engine is output by the force-taking device, and the fire pump is driven by a set of transmission equipment. The water and foam are mixed in a certain proportion by the fire pump and foam-share mixing equipment, and then the fire-fighting gun and foam-life-saving gun are sprayed to save the life. Therefore, it is necessary to satisfy the necessary load and engine power of the chassis. National standards have been formulated. Chassis selection is based on the National Standard of "General Chassis Series, Types, Basic Parameters and Skills Requirements for Fire Engines", and engine power selection is necessary to meet the requirements of the rules in accordance with the requirements of Appendix A to the Professional Standard "General Skills Conditions for Foam Fire Engines".
1、动力输出设备

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。
Domestic foam fire trucks mostly use the main engine to take the force. There are many ways to install the force harvester. Now the medium and heavy foam fire trucks mostly use the sandwich type (transmission front type) and the transmission shaft to take the force (transmission rear type) between the main clutch and the transmission. The power of the main engine is taken out by a sandwich force taker and transmitted to the water pump through the transmission system to drive the water pump. The double-acting function can be realized. Most of them choose 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。
The water-foam tank is the primary container for loading the life-saving agent on the foam fire truck. According to the development of the fire fighting profession, it can be made from many kinds of materials. In the 1980s and 1990s, polyester fiberglass reinforced plastic materials were mostly used. Now it is gradually developed to use high-quality carbon steel materials and stainless steel materials.
