Mobile push-cart foam fire extinguishing units are widely used in residential areas, industrial and mining enterprises, oil depots, chemical departments, heat treatment workshops, gas stations, and other locations.

41. Mobile Pushcart Foam Fire Extinguishing Device Working Principle: When 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 tube. It is mixed with the pressurized water in a predetermined ratio to form a foam mixture. When the foam mixture, under certain pressure, passes through the foam gun, it吸取air, causing the mixture to foam and spray over the burning liquid surface, extinguishing the fire.

42. Pressure-foam Ratio Mixture Unit (Vertical): Composed of foam liquid storage tank, capsules, pressure ratio mixer, safety valve, control valve, and some auxiliary components. When the fire suppression water pressure flows through this equipment, the ratio mixer diverts it proportionally.

45. Pressure-Driven Foam Ratio Mixing Unit (Horizontal Type): It consists of a foam liquid storage tank, capsules, pressure ratio mixer, safety valve, control valve, and some auxiliary components. When fire water 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 equipped with capsules, squeezes the capsules, and the displaced foam liquid mixes with the fire water in the main pipeline to form a foam mixture of a certain ratio, which is then supplied to the foam-producing equipment.

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