41. Mobile Pushcart Foam Fire Extinguishing Device Operation Principle: When fire extinguishing is required, connect the foam gun and proportioning mixer with a firehose. Connect the firehose to the inlet of the proportioning mixer and introduce pressurized water. As the pressurized water flows at a high speed through the nozzle of the proportioning mixer, a negative pressure is formed inside the mixer. Under the action 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.

45. Pressure-Driven Foam Ratio Mixing Unit (Horizontal Type): Comprised of a foam liquid storage tank, capsules, pressure-driven ratio mixer, safety valve, control valve, and some auxiliary components. As fire water pressure flows through this equipment, the ratio mixer diverts it proportionally. A small portion of the water enters the interlayer of the foam liquid storage tank with capsules, squeezes 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 Proportioning Mixers (Horizontal Type): Suitable for mixing ratios of 3% or 6% foam liquids, these mixers are widely used in oil storage tank areas, chemical plants, aircraft hangars, oil fields, fuel power plants, boiler rooms, underground parking garages, hazardous material warehouses, and chemical product warehouses, as well as in water spray systems integrated with foam systems.
