Semi-stationary (portable) foam extinguishing outfit
-
1 Overview
The semi-fixed (portable) foam fire
extinguishing device is a fire fighting device that mainly extinguishes Class B
fires by mobile means. It can be used as a stand-alone mobile foam fire
extinguishing system or as an auxiliary fire extinguishing system for fixed
foam fire extinguishing systems.Product implementation standards: GB
20031-2005 “General technical conditions for foam fire extinguishing
systems and components.”2 Application range
Widely used in hangars, underground
garages, gas stations, ocean-going vessels and petrochemical areas.3 composition
It is mainly composed of wheeled frame,
liquid storage tank, pipeline foam proportioning mixer, PQ air foam gun and
fire hose.4 Working principle
Pressure water is supplied from the fire
hydrant or hand lift fire pump, fire truck, etc. through the fire hose to the
pipeline foam proportioner (Part 4), and the foam stock stored in the liquid
storage tank (Part 6) is passed through the suction pipe (Part 5) Automatically
inhaled, the two are mixed with each other to form a foam mixture of a certain
mixing ratio, and then the foam mixture is turned into an air foam by a PQ type
air foam gun (Part 7), and is sprayed out to extinguish the fire.
