PY100 foam fire extinguishing device PY300 mobile foam fire extinguishing device

Foam fire extinguishing device Mobile foam fire extinguishing device
The mobile foam fire extinguishing device is mainly composed of an atmospheric pressure foam liquid storage tank, a foam gun, a pipeline proportional mixer, a fire hose, and a cart frame.
It can be used by connecting the fire hose carried by the device itself to water supply equipment such as fire hydrants, and can be placed at a favorable location to extinguish the fire. As a supplement to the fixed fire extinguishing device, it can be used for fire extinguishing protection of multiple equipment in the protective area. The appropriate foam liquid type can be selected as needed to extinguish various liquid fires. Mobile foam fire extinguishing devices are widely used in oil depots, petrochemical enterprises, oil pump rooms, gas stations and other places.
Working Principle
When it is necessary to extinguish a fire, use a fire hose to connect the foam gun and the proportional mixer. The inlet end of the proportional mixer is connected to the fire hose and connected to the pressure water. When flowing through the nozzle of the proportional mixer, a negative pressure is formed in the chamber of the proportional mixer. The foam liquid in the foam liquid storage tank enters the mixer through the suction pipe under the pressure of the atmosphere, and is mixed with the pressure water in a predetermined ratio to form foam. Mixture. When the foam mixture with a certain pressure passes through the foam gun, air is sucked in, causing the foam mixture to foam and spray to cover the surface of the burning liquid to extinguish the fire.
Scope of application:
Suitable for extinguishing general Class B fires, such as oil products, grease and other fires. It can also be applied to Class B fires, but it cannot extinguish water-soluble flammable and flammable liquids in Class B fires. Fires involving substances such as alcohols, esters, ethers, ketones, etc. cannot also be used to extinguish live equipment and similar fires.
Features of water-based (foam) fire extinguishers:
Non-toxic, non-polluting, clean, efficient in extinguishing fire, and good in re-ignition resistance. It is especially suitable for extinguishing fires burning flammable liquids and solid organic matter, such as gasoline, diesel, wood, paper, rubber, cotton and linen and other products.
Suitable places:
Initial fires in crowded places, such as office buildings, cars, trains, airplanes, ships, theaters, hotels, homes, conference halls, sports venues, libraries, etc.
Because this type of fire extinguisher has a long spray distance and a long continuous spray time, it can give full play to its advantages and be used to extinguish initial fires in large-area storage tanks or oil tankers.
Foam fire extinguishers should be stored in a dry, cool, ventilated and easily accessible place. They should not be near high temperatures or places that may be exposed to the sun to prevent carbonic acid from decomposing and becoming ineffective. Antifreeze measures should be taken in winter to prevent freezing and should be wiped frequently. Remove dust and clear the nozzle to keep it clear.
