(I) Product description
PY mobile low-expansion foam fire extinguishing device is used to extinguish class B fires and A and B mixed fires; it can be used as a fire protection device independently, and can also cooperate with large-scale fixed foam fire extinguishing systems to assist in fire fighting. And oil refineries, petroleum, chemical companies, oil transportation ports, aircraft hangars, garages, warehouses, gas stations and other places. It has good maneuverability, flexibility and convenience, and can be combined with foam grab, foam generator and other low, medium and high multiple foam fire extinguishing systems.
(Two) working principle
The tank body of PY mobile low multiple foam fire extinguishing device is made of Q235 steel plate. It adopts PHF negative pressure proportional mixer. It uses Venturi principle to make negative pressure at the outlet, and sucks the foam liquid from the storage tank through the suction pipe. Proportional mixer, mixed with water to form a foam mixed liquid, and form air foam through an air foam gun for fire extinguishing.
