Foam fire extinguishing system can be divided into low foam fire extinguishing system with foaming ratio less than 20 times; medium multiple foam fire extinguishing system with foaming rate of 20~200 times; high expansion foam fire extinguishing system with foaming ratio of 200~1000 times. Next, let's take a look at the foam extinguishing agent manufacturer to introduce the foam extinguishing system.

1. foam fire extinguishing agent manufacturers-low expansion foam fire extinguishing system.

Low expansion foam fire extinguishing system can be divided into low expansion foam fire extinguishing system and foam spray fire extinguishing system. Low expansion foam fire extinguishing system is suitable for processing, storage, loading and unloading, use a (except liquefied hydrocarbon), B, C and other liquid places. Such as: oil field, oil refinery, chemical plant, railway tanker crane pipe trestle, dock, underground garage, aircraft hangar, airport, fuel boiler room and other places.

The low expansion foam fire extinguishing system is mainly composed of fire pump, foam proportional mixing device, foam generator, foam nozzle, rain valve and other valves and pipe fittings. Under a certain pressure, the fire water is mixed with the foam liquid through the foam mixing device to form a foam mixture with a certain proportion. The air foam is produced by a foam generator, and the foam nozzle flows down along the protective tank wall to cover the surface of the burning liquid, so as to achieve the purpose of suffocation and fire extinguishing.

2. foam fire extinguishing agent manufacturers-foam nozzle fire extinguishing system.

The automatic sprinkler system is equipped with foam mixture supply equipment to form a fixed fire extinguishing system with water spray and foam spray. It can be an open system or a closed system. Shenzhen used the system earlier. When a fire occurs, the fire detector installed in the protected area sends a signal to the control cabinet, and the glass ball that closes the nozzle breaks and water is sprayed. At this time, the shower valve, fire pump and pipeline valve are manually or automatically opened, and the system works. The pressure fire water is mixed with foam liquid through a foam ratio mixing device to form a certain proportion of foam mixture, and air foam is generated through the nozzle to achieve the fire extinguishing effect. The foam sprinkler system is mainly composed of fire pump, foam proportional mixing device, nozzle, water flow indicator, wet alarm valve, rain valve and other valves, pipelines, etc. Specific classification is as follows:

According to the way of use can be divided into: open foam sprinkler system and closed foam sprinkler system.

The nozzle of this system can adopt foam nozzle or nozzle.

When choosing a spray head, use an aqueous film-forming foam or a film-forming fluoroprotein foam.

The foam water spray system is also called ZP system. ZP32 is a fully automatic foam spray system with a mixed flow rate of 32L/s.

3. foam fire extinguishing agent manufacturer-high multiple, medium multiple foam fire extinguishing system

Medium and high expansion foam fire extinguishing system is suitable for Class A and Class B fires, limited enclosed space fires, and control of liquefied petroleum gas and liquefied natural gas flow fires. Such as: solid material warehouse, combustible liquid warehouse, industrial plant, underground construction, all kinds of ship engine room, pump room, cargo hold and other fire dangerous places, precious equipment materials, combustible liquid and liquefied petroleum gas, liquefied natural gas flow fire. High-multiplier, medium-multiplier foam fire extinguishing system is mainly composed of fire pump, foam proportional mixing device, foam generator, valve, pipeline, etc.
