41. Operating Principle of Mobile Push Cart Foam Fire Extinguishing Equipment: When fire extinguishing is required, connect the foam gun and proportioning mixer with a fire hose. Connect the fire hose to the inlet of the proportioning mixer and introduce pressurized water. As the pressurized water flows at high speed through the nozzle of the proportioning mixer, a vacuum is formed inside the mixer. Under the force of atmospheric pressure, foam liquid from the foam liquid storage tank enters the proportioning mixer through a suction pipe. It is mixed with the pressurized water in a predetermined ratio to form a foam mixture. When the foam mixture, at a certain pressure, passes through the foam gun, it吸入 air, causing the foam mixture to foam and spray over the burning liquid surface, extinguishing the fire.

A small portion of the water enters the foam liquid storage tank interlayer with capsules, compresses the capsules, and the displaced foam liquid mixes with the remaining main pipeline fire water to form a foam mixture of a specific ratio, which is then supplied to the foam generating equipment.

46. Pressure-actuated Foam Ratio Mixture Device (Horizontal Type): Suitable for mixing foam liquids at ratios of 3% or 6%.
