Working Principle
When the mobile foam fire extinguishing device is extinguishing the fire, the pipe joints at both ends of the pipeline proportional mixer are connected to the fire hose, and connected to the pressure water source. When water with a pressure of not less than 0.6MPa flows through the proportional mixing at a high speed When the nozzle of the mixer is used, due to the diffusion effect of the lateral movement of the jet particles, a vacuum (negative pressure) is formed in the chamber of the proportional mixer, so the foam liquid in the foam liquid storage tank enters the mixer through the suction pipe under atmospheric pressure. It is mixed with pressure water to reach a certain proportion of mixed liquid, and the foam is sprayed by foam gun and foam generator to extinguish the fire.
