31. Foam Fire Extinguisher: An essential component of foam fire suppression systems, particularly suitable for areas handling flammable and combustible liquids on a large scale, where fire hazards are prevalent during production, storage, and use.

32. Foam Fire Extinguisher Working Principle: The foam extinguisher is mainly composed of flanges, cylinders, ball valves, internal joints, fire hoses, and end caps. It is distributed and installed at predetermined locations within the protected area. The flange is connected to the supply pipeline, with the ball valve closed and the end cap sealed during normal operation.

33. Foam Fire Extinguisher Working Principle: In the event of a fire, first unscrew the end cap, then attach the fire hose, and finally open the ball valve to deliver foam liquid to the foam generator. The foam fire extinguisher must be used within the specified pressure range.

34. High-multiplicity air foam generator: Capable of quickly mixing foam solution with air to form a large amount of foam, which rapidly covers the burning area, isolating it from air to achieve fire extinguishing.

Used in aircraft hangars, car parks, oil depots, mines, liquefied petroleum gas stations, oil terminals, libraries, archives, and more.

36. Low-Expansion Air Foam Generator: A device that mixes foam concentrate from a proportioning system with inhaled air to produce foam, which is then sprayed onto the surface of the burning liquid to form a foam layer. This layer isolates air, absorbs heat, and thus extinguishes the fire. Generally used for extinguishing Class A and B fires, primarily for oil fires.

37. Medium Expansion Air Foam Generator: Comprised primarily of nozzles, foaming mats, and foam chambers, this equipment generates and喷射s medium expansion foam.

The mobile pushcart foam fire extinguishing equipment 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 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 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 the 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 draws in air, causing the mixture to foam and spray over the burning liquid surface, extinguishing the fire.

42. Pressure-Driven Foam Ratio Mixing Unit (Vertical): It consists of a 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. 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 specific ratio, which is then supplied to the foam generating equipment.

43.

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-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 with capsules, squeezes the capsules, and the displaced foam liquid mixes with the remaining fire-fighting 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-Driven Foam Ratio Mixing Unit (Horizontal Type): Suitable for mixing foam fluids at ratios of 3% or 6%, this unit 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 in water spray systems integrated with foam systems.

69. Foam Fire Extinguishing System: Selection and Installation Requirements for Foam Fire Pumps and Foam Mixing Pumps: Foam fire pumps and foam mixing pumps should be selected with a flat characteristic curve centrifugal pump, and their working pressure and flow rate should meet the system design requirements. When using a hydraulically driven balanced proportioning mixing device, the water flow rate consumed should be included in the rated flow of the foam fire pump. When using a recirculating pump type proportioning mixer, the rated flow of the foam mixing pump should be 1.1 times the system design flow. A vacuum pressure gauge or vacuum gauge should be installed on the pump inlet pipe; a pressure gauge, check valve, and a return pipe with a control valve should be installed on the pump outlet pipe.

70. Foam Fire Extinguishing System: The selection and setup requirements for foam liquid pumps: The working pressure and flow rate of the foam liquid pump should meet the system design requirements and match the working pressure and flow rate range of the selected proportioning device. It should also ensure that the foam liquid supply pressure is greater than the water pressure at the design flow rate; the structural form, sealing, or filling type of the foam liquid pump should be suitable for transporting the selected foam liquid, and its material should be resistant to foam liquid corrosion without affecting the performance of the foam liquid; a standby pump should be equipped, with the specifications and models of the standby pump identical to the working pump, allowing for automatic or manual switching to the standby pump in case of a working pump failure; the foam liquid pump should withstand at least 10 minutes of no-load operation; except for hydraulic-driven pumps, a power source should be set.
