31. Foam Fire Extinguisher: A crucial component of the foam fire suppression system, particularly suitable for areas with fire hazards involving flammable and combustible liquids, where they are produced, stored, or used.

32. Foam Fire Extinguisher Operation Principle: The foam extinguishing hydrant is mainly composed of flanges, cylinders, ball valves, internal fittings, fire hose couplings, and end caps. It is distributed and installed at predetermined positions within the protected area. The flanges are 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 connect the fire hose, and finally open the ball valve to supply foam liquid to the foam generator. The foam fire extinguisher must be used within the specified pressure range.

It effectively removes smoke and toxic gases, suitable for full or partial flooding in confined spaces. Used in hangars, garages, oil depots, mines, liquefied petroleum gas stations, oil terminals, libraries, archives, and other similar venues.

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 thereby extinguishes the fire. Generally used for extinguishing Class A and B fires, it is primarily used for oil fires.

37. Medium-Expansion Air Foam Generator: Composed mainly of nozzles, foaming screens, and foam cannons, it is a device designed to produce and喷射 medium-expansion foam.

The mobile push cart 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. The working principle of the mobile pushcart-type foam fire extinguishing device: 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 vacuum 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 tube. It is mixed with the pressurized water in the 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 foam mixture to foam and spray over the burning liquid surface, extinguishing the fire.

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

The displaced foam liquid is mixed with the fire-fighting water in the main pipeline to form a foam mixture at a specific ratio, which is then supplied to the foam-producing equipment.

45. Pressure-Regulated Foam Ratio Mixing Unit (Horizontal Type): Composed of foam liquid storage tank, capsules, pressure-regulated ratio mixer, safety valve, control valve, and some auxiliary components. When fire protection water pressure flows through this equipment, the ratio mixer分流s 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 water in the main pipeline to form a foam mixture at a certain ratio, which is then supplied to the foam generating equipment.

46. Pressure-foam Ratio Mixture Device (Lateral Type): Suitable for mixing ratios of 3% or 6% for various foam liquids. Widely used in oil storage tank areas, chemical factories, aircraft hangars, oil fields, fuel power plants, boiler rooms, underground garages, hazardous material warehouses, and chemical product warehouses, as well as water spray——foam interconnect systems.

It is easy to operate and maintain, occupies less space, and can be used for automatic control. 6. Available in various capacities of foam liquid storage tanks and different flow ratio mixers, it can meet the needs of various foam-producing equipment. 7.

69. Foam Fire Extinguishing System: Selection and Installation Requirements for Foam Fire Pump and Foam Mixing Pump: The foam fire pump and foam mixing pump should be centrifugal pumps with a smooth characteristic curve, and their working pressure and flow rate should meet the system design requirements. When using a hydraulic-driven balanced ratio mixing device, the water flow consumed should be included in the rated flow of the foam fire pump. When using a circulator-type ratio 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 pipeline; a pressure gauge, check valve, and a return pipe with a control valve should be installed on the pump outlet pipeline.

70. Foam Fire Extinguishing System: Selection and Installation 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. Simultaneously, ensure that the foam liquid supply pressure under the design flow is greater than the water pressure. The structural type, seal, or filling of the foam liquid pump should be suitable for the transport of the selected foam liquid, and the materials should be resistant to corrosion by the foam liquid without affecting its performance. A standby pump should be installed, with the specifications and models of the standby pump identical to the operating pump, allowing for automatic and manual switching to the standby pump in case of a failure in the operating pump. The foam liquid pump should withstand at least 10 minutes of no-load operation; in addition to hydraulic-driven pumps, a power source should be set.
