Product Details

Mobile foam fire extinguishing device

1、 Explanation

PY mobile (car) foam fire extinguishing device is a portable and flexible wheeled fire extinguishing deviceFire extinguishing equipment. It adopts PHF type pipeline (negative pressure) proportional mixer, which can be used with foamThe gun and foam generator form a low, medium and high expansion foam fire extinguishing system. When pressure water flows throughWhen passing through the mixer, water is mixed with foam liquid in a certain proportion, and passes through the foam gun and foam generatorSpray foam to extinguish the fire. By trolley, normal pressure foam tank, negative pressure proportioner, sprayingIt consists of equipment, water hoses, safety valves, control valves, and some auxiliary components.Advantages: small pressure drop loss, large energy of sprayed foam, and strong penetration ability. Can quicklyExtinguish fires; The mixing ratio is quite stable, accurate and reliable, and can provide high-quality foamFoam mixture; Strong maneuverability, its lightweight and flexible fire extinguishing performance covers a wide range, and the fire extinguishing effect is good.

2、 Working principle

When the mobile foam fire extinguishing device extinguishes the fire, the pipe tooth interfaces at both ends of the pipeline proportional mixer are connected with the fire hose, and the pressure water source is connected. When there is water with a pressure of not less than 0.6MPa flowing through the nozzle of the proportional mixer at a high speed, due to the diffusion effect of the transverse movement of the jet particles, a vacuum (negative pressure) is formed in the room of the proportional mixer, so the foam liquid in the foam liquid storage tank enters the mixer through the suction pipe under the pressure of the atmosphere, mixes with the pressure water, and finally reaches a certain proportion of the mixed liquid, which is sprayed by the foam gun and the foam generator to extinguish the fire.

4、 Usage method

Generally, it is operated by two people, one person connects the water jet hose and holds a gun to extinguish the fire, and the other person connects the fire hydrant hose and opens the fire hydrant ball valve to supply water.

1. Connect the water supply source to the pressure water inlet of the equipment using a fire hose.

2. Remove the spray gun and deploy its fire hose.

3. Connect the water hose of the spray gun to the outlet of the equipment.

4. Open the water supply source.

5. Hold a foam spray gun to extinguish the fire.
