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. Operation Principle of Mobile Pushcart Foam Fire Extinguishing Device: 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 vacuum is formed inside the mixer. Under the action of atmospheric pressure, the foam liquid in 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 foam mixture to foam and spray over the burning liquid surface, extinguishing the fire.

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

45. Pressure-Regulated Foam Ratio Mixing System (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 suppression water flows through this equipment, the ratio mixer divides 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 is mixed with the remaining fire water in the main pipeline to form a foam mixture at a specific ratio, which is then supplied to the foam-producing equipment.

46. Pressure-actuated Foam Ratio Mixing Unit (Horizontal Type): Suitable for mixing ratios of 3% or 6% foam liquids, 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 water spray systems integrated with foam systems.

69. Foam Fire Extinguishing System: Selection and Installation Requirements for Foam Fire Pumps and Foam Mixture Pumps: Foam fire pumps and foam mixture pumps should be selected with a smooth characteristic curve centrifugal pump, and their working pressure and flow rate should meet the system design requirements. When using a hydraulically driven balanced ratio mixing device, the water flow consumed should be included in the rated flow of the foam fire pump. When using a recirculating pump type ratio mixer, the rated flow of the foam mixture 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, a 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 Pump: The working pressure and flow rate of the foam pump should meet the system design requirements and match the working pressure and flow rate range of the selected proportioning device. At the same time, the supply pressure of the foam under the design flow rate should be greater than the water pressure. The structural form, seal or filling type of the foam pump should be suitable for conveying the selected foam, and the materials should be resistant to foam corrosion without affecting the performance of the foam. A standby pump should be provided, with the same specifications and models as the operating pump. The system should be able to switch automatically and manually to the standby pump in case of failure of the operating pump. The foam pump should withstand at least 10 minutes of no-load operation. In addition to hydraulic-driven pumps, a power source should be set up.
