Mobile foam fire extinguishing devices are widely used in oil depots, petrochemical enterprises, oil pump rooms, gas stations, and other locations. Working Principle When fire extinguishing is required, connect the foam monitor and proportioner with a fire hose. The inlet end of the proportioner is connected to the fire hose and pressurized water. When pressurized water flows through the nozzle of the proportioner at high speed, a negative pressure is formed inside the proportioner chamber. The foam concentrate in the foam storage tank is drawn into the proportioner through the suction pipe under atmospheric pressure, mixing with the pressurized water in a predetermined ratio to form foam solution. When the foam solution, under pressure, passes through the foam monitor, it draws in air, causing the foam solution to foam and spray, covering the surface of the burning liquid to extinguish the fire.
