Low expansion air foam generator Fire fighting equipment matching foam generator Shandong Dongyue

Description :

　　The air foam generator, also known as the air foam generator, is a fire-fighting device installed on the tank wall of the upper ring plate of the oil tank for spraying foam when the oil tank is put out of fire. The nozzle is sealed off from the air in the tank with thin glass sheets (or diaphragms) to prevent the oil or gas in the tank from entering the foam room or the fire pipeline.

　　The type and number of foam generators installed in oil tanks are determined by calculation according to the capacity of oil tanks, the type of oil products stored, the size of oil surface, and the type of foam, but the number shall not be less than two, and each has a separate fire pipeline to supply foam mixture.

　　When the foam mixed liquid flow supplied by the fixed fire pump of the foam fire truck passes through the generator through the transmission pipeline, it forms air foam to extinguish the oil fire. There are generally four models: PC-4, PC-8, PC-16, and PC-24.

　　Characteristics of the foam generator for liquid spraying foam extinguishing system

　　The foam generator of the liquid spraying foam extinguishing system is installed on the upper part of the oil tank wall, and the sprayed foam covers the whole burning liquid surface for extinguishing.

　　Scope of application: The liquid spraying foam extinguishing system is applicable to three types of storage tanks with fixed roof, external floating roof and internal floating roof.

　　Advantages: Compared with the underwater spraying foam fire extinguishing system, the above liquid type has lower cost, and foam is not easy to be polluted by oil products.

　　Disadvantages: When the oil tank explodes, the foam mixture pipeline and the foam generator are easy to be damaged, causing the fire out of control.

　　The foam in the underwater spraying foam extinguishing system is sprayed from the bottom of the oil tank through the foam injection port, and then rises through the oil layer to the burning liquid level and spreads to cover the entire liquid level to extinguish the fire.
