41. Mobile Push Cart Foam Fire Extinguishing Device Operation Principle: When fire extinguishing is required, connect the foam gun and proportioning mixer using the fire hose. Connect the fire hose to the proportioning mixer's inlet 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 atmospheric pressure, the foam liquid in the foam liquid storage tank enters the proportioning mixer through the suction tube. It mixes with the pressurized water in the predetermined ratio to form a foam mixture. When this foam mixture, under 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.

Simultaneously, 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, with materials that are resistant to foam liquid corrosion and do not affect the foam liquid's properties. A standby pump should be equipped, with the same specifications and models as the working pump, capable of automatically and manually switching to the standby pump in case of a working pump failure. The foam liquid pump should withstand no-load operation for at least 10 minutes. In addition to hydraulic-driven pumps, a power source should be set up.
