 Product Description

一、 移动式泡沫灭火装置的构成:
执行标准:GB20031-2005
半固定式泡沫灭火装置也叫推车式泡沫灭火装置,是新型移动式泡沫灭火装置,其操作迅速简便、可靠性强,用于扑灭甲、乙、丙类非水溶性液体火灾。被广泛用于市政住宅区、厂矿企业、油库、化工部门、热处理车间、加油站,大小型船舶等场所,主要由泡沫液储罐、喷枪、比例混合器、水带、及推车手柄和底轮等构成。

二、移动式泡沫灭火装置的工作原理:
移动式泡沫灭火装置在灭火时其管线式比例混合器的两端的管牙接口与消防水带连接,并连接压力水源,当有不低于0.6MPa压力的水以很高的速度流过比例混合器的喷嘴时,由于射流质点的横向移动的扩散作用,比例混合器的室内形成真空(负压),于是泡沫液储罐内的泡沫液在大气的压力作用下通过吸液管进入混合器,与压力水混合,最终达到一定比例的混合液。当具有一定压力的混合液流到泡沫喷枪时,因为喷枪的性能会吸入一定量的空气,使泡沫混合液发泡,从而达到泡沫灭火的效果。

注:使用泡沫液类型:1.蛋白泡沫液,氟蛋白泡沫液 ,抗溶性氟蛋白泡沫灭火剂 2.使用温度范围:0℃~55℃

四、移动式泡沫灭火装置的使用方法:
装置一般应由两人操作:一人接喷射泡沫枪带并持枪灭火,另一人接消防栓水带并打开消防栓球阀供水。其操作步骤如下:
1)用消防水带将供水源与设备的压力水进口相联接;
2)取下泡沫喷枪并展开其消防水带;
3)将喷枪的联接水带与设备的出接口联接;
4)打开供水源供水;
5)手持泡沫喷射枪进行灭火。

五、移动式泡沫灭火装置的维护与保养:
1)灭火剂的灌装:设备使用后,用户必须购置同类型的泡沫灭火液进行补充灌装;灌装时可用塑料管吸入或用漏斗从加液口注进;灌装完毕后拧紧加液口盖,以防设备移动时泡沫液溅出。
2)设备应放在阴凉、通风、进出取用方便的处所。
3)本设备罐体材料采用耐腐性的碳钢材质制造,严禁用力敲打、造成罐体内防腐层脱落。
4)长期存放未使用本设备,应每年复检一次泡沫液质量是否变质,若发现变质应及时更换。
5)本设备每次使用后,应认真清洗消防水带并将其晾干后再缠绕在设备卷盘上,(建议用户自备备用消防水带,以防突发性火情发生)。
6)为了使设备长期处于良好的防火状态及罐内泡沫液的质量,泡沫储罐应每3年打开清洗一次使用
7)当供水源为机动水压泵或消防水罐车时,供水压力应不大于1.0MPa。购置设备时应配置能承受工作压力≥1.0MPa消防水带。
