The mobile push cart foam fire extinguishing device is widely used in residential areas, industrial and mining enterprises, oil depots, chemical departments, heat treatment workshops, gas stations, and other locations.

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

42. Pressure-foam ratio blending unit (vertical type): It consists of a foam liquid storage tank, capsules, pressure ratio blender, safety valve, control valve, and some auxiliary components. When the fire-fighting water pressure flows through this equipment, the ratio blender diverts it proportionally. A small portion of the water enters the interlayer of the foam liquid storage tank equipped with capsules, squeezing the capsules. 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.

43.

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

46. Pressure-Regulated Foam Ratio Mixing Device (Horizontal Type): Suitable for mixing ratios of 3% or 6% for various foam liquids. This device is widely used in oil storage tank areas, chemical factories, aircraft hangars, oil fields, fuel power plants, boiler rooms, underground parking garages, hazardous material warehouses, and chemical product warehouses, as well as water spray systems integrated with foam systems.
