 Product Description

一、高倍数泡沫发生器产品介绍:
执行标准:GB20031-2005
PF4高倍数泡沫发生器是高倍数泡沫灭火系统的主要设备之一,可以用在固定灭火装置上,也可以用在移动灭火装置上,其特点是发泡量大,适宜扑灭各种不同类型的火灾。

二、工作原理
PF4型高倍数泡沫灭火装置主要由贮罐、高倍数泡沫发生器、车/固定架等组成使用时先用水带的一头接在消防车或消防栓的接头上,把水带的另一头接到发生器的进水口上,然后打开消火栓,此时水通过水轮机使风轮转起来,由喷头把混合液喷到发生器的发泡网上,风轮产生的风力把附在发泡网上的泡沫液吹成大量的气泡淹没或覆盖在燃烧物的表面。利用泡沫遮盖冷却和窒息作用达到灭火目的。

四、安装及维护保养
1、安装
(1)、距离泡沫发生器空气进气口端300cm以内不应有遮挡物。
(2)、在泡沫发生器的发泡网前进1m以内不应有阻碍泡沫喷放的障碍物。
(3)、用在全淹没系统的泡沫发生器,安装高度应高于泡沫设计到达的高度。
(4)、发泡网应面对保护区。

2、维护保养
(1)、经常清洁发泡网,任何时候发泡网上不许有杂物。
(2)、泡沫发生器每经过一次喷射都应用清水冲洗干净。
(3)、泡沫发生器每年检修一次,在检修组装完毕后,用1.0MPa的水压密封试验。所有零件及连接处都不能有渗漏或明显变形。
(4)、安装好的设备不能随意拆卸,以免损失性能。
