product description

Product introduction

PF high expansion foam generator is one of the main equipments of high expansion foam fire extinguishing system. It is fixedly installed in the protective area, and has the advantages of large foaming capacity, strong fire extinguishing capacity, and fast speed. It is suitable for large-scale fire extinguishment in closed and limited spaces, such as aircraft hangars, tank farms, chemical plants, workshop warehouses, and LNG stations.

Structure and working principle

The pressure water is provided by the fire pump, and the foam mixed liquid is formed by the pressure-type proportional mixing device, which drives the wind turbine of the high-multiplier foam generator to rotate. The layer of film is blown to form a large amount of foam by the wind that is blown onto the net by the wind wheel, and is constituted as a high-magnitude foam, which floods or covers the surface of the burning object. The use of foam to block heat radiation, cool down, isolate dilute air, cover suffocation and other properties to achieve the purpose of fire extinguishing. Effectively prevent the spread of fire.

Fourth, installation precautions

1. There should be no obstructions within 0.3m from the air inlet of the foam generator.

2. Within 1m in front of the foaming net of the foam generator, there should be no obstacles preventing the foam from being discharged.

3. The installation height of the foam generator used in the fully submerged system should be higher than the height reached by the foam design.

4. Clean the foam net frequently. No debris on the foam net at any time.

5. It is best to install a filter at the water inlet to prevent the turbine from being blocked by debris in the fire water.

V. Maintenance

1. Frequently clean the foam net. No debris is allowed on the foam net at any time.

2. Every time the foam generator is sprayed, it should be rinsed clean.

3. The foam generator is overhauled once a year. After the overhaul and assembly is completed, the seal test is performed with pressurized water. All parts and connections must not have leakage or obvious deformation.

4. The installed equipment cannot be disassembled at will to avoid loss of performance.
