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 create foam, which is then sprayed onto the surface of the burning liquid to form a foam layer. This layer isolates the air, absorbs heat, and ultimately extinguishes the fire. Generally used for extinguishing Class A and B fires, it is primarily employed for oil fires.

37. Medium-Foam Generator: Comprised mainly of nozzles, foaming meshes, and foam nozzles, this device produces and ejects medium-foam, and can be paired with foam fire trucks, water tank fire trucks, and portable fire pumps with pipeline-type proportioning mixers.

The portable 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. The working principle of the portable pushcart type foam fire extinguishing device: 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. The foam liquid in the foam liquid storage tank is drawn into the proportioning mixer through the suction tube under the action of atmospheric pressure, mixed with the pressurized water in the predetermined ratio, forming a foam mixture. When the foam mixture, under a certain pressure, passes through the foam gun, it absorbs 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): Composed of foam liquid storage tank, capsules, pressure-driven ratio mixer, safety valve, control valve, and some auxiliary components. When fire water pressure flows through this equipment, the ratio mixer diverts it proportionally.

45. Pressure-foam Ratio Mixing System (Horizontal Type): It consists of a foam liquid storage tank, capsules, pressure ratio mixer, safety valve, control valve, and some auxiliary components. When the fire hydrant water pressure flows through this equipment, the ratio mixer分流 it proportionally, with a small portion of water entering the foam liquid storage tank's interlayer containing the capsules, squeezing the capsules, and the displaced foam liquid mixing with the fire water in the main pipeline to form a foam mixture of a certain ratio, which is then supplied to the foam generating equipment.

46.
