High-expansion foam generator
Product Introduction
The PSF-4 high-expansion foam generator is one of the main
devices in the high-expansion foam fire extinguisher system. This
product has a large foaming capacity and is suitable for
extinguishing various types of fires.
Working principle
The water wheel is driven by a foam mixture at a pressure of
0.3 to 1.0MPa to rotate the Feng Lun. The mixture is sprayed in a
mist form onto the foaming net through the nozzle, forming a film
on the surface of the net. The wind blown onto the net by the wind
wheel expands into a large number of bubbles, forming a
high-expansion cheongsam that subuncovers or covers the surface of
the burning object.
The purpose of fire extinguishing is achieved by taking
advantage of the blocking, cooling and suffocation effects of foam.
In total flooding and local application high-expansion foam fire
extinguishing systems, it is fixed in the protected area to achieve
the purpose of fire suppression.
Main technical parameters
| Model specification | Mixed liquid flow rate
(L/S) | Inlet pressure
(MPa) | Foaming amount
(m³/min) | Foaming ratio |
| PFS-4 | 2.4-4.75 | (0.3-1.0)MPa | 35-200 | 201-1000 |
Installation
- There must be no obstructions within 3 meters from the air inlet
end of the foam generator.
- There shall be no obstacles hindering the discharge of foam within
1 meter in front of the foaming net of the foam generator
- Foam generators used in total flooding systems must be installed at
a height higher than the designed height of the foam
- The foaming net should face the protected area
Maintain self-cultivation
- Clean the foaming net frequently. At no time should there be any
debris on the foaming net
- The foam generator should be thoroughly rinsed with clean water
after each injection
- The foam generator should be overhauled once a year. After the
overhaul and assembly are completed, a water pressure test of
1.25MPa should be conducted for sealing. There shall be no leakage
or obvious deformation at all parts and connection points.
- When not in use, cover the equipment with a rainproof cloth to
avoid wind and sun exposure and extend its service life
