What Are The Characteristics Of The Compressed Air Foam Fire Engine

Performance characteristics of compressed air foam fire truck (1) good coverage, high fire extinguishing efficiency, more safe. Compressed air foam fire truck is compressed air, efficient enrichment foam fluid and water as one way of strong gush out, attached to the bubble area is large, the water film on the absorption of heat absorption ability, foam and have the function of the air, at the same time special foaming agent can prevent chemical chain reaction, fire extinguishing effect is far better to traditional foam, water tank truck. Foam agent can obviously reduce the tension between water molecules, so that foam liquid has a strong permeability, can penetrate into the interior of the combustion, greatly shorten the time to extinguish the fire. Because of the rapid cooling, can reduce the risk of flashover and reignite, reduce the formation of smoke, therefore, the combatants do not have the burden of high temperature, can greatly reduce the danger of the combatants. (2) less water for fire control and effective reduction of water damage. With the accelerating urbanization, the cities for the construction of the fire hydrant system is far behind the development of the construction and population, fire hydrant water supply ability is low, most of the regional water supply is not more than 25 l/S, which is generally equipped with car monitor (40 ~ 50 l l/S/S) cannot be continuous injection, often can not support more than four fire hoses used for fire extinguishing and cooling protection at the same time. For large and medium-sized fire sites, it is often necessary to mobilize more than one fire truck long-distance water supply for fire fighting needs. The water used by CAFS to directly put out class A fires is less than 1/3 of the traditional water consumption, and the water used for cooling protection by dry foam is only 1/10 ~ 1/20 of the traditional water consumption. The application of CAFS fire trucks enables the fire fighting forces to realize the capability of continuous fire extinguishing with vehicle-mounted fire cannons under the existing urban fire hydrant water supply conditions, as well as the combat capability of using 8 ~ 10 fire hoses simultaneously for fire extinguishing and cooling protection in a fire area. The promotion and application of CAFS will significantly improve the severe situation that the water supply capacity of urban fire hydrants restricts the fire fighting ability of fire fighting forces. Compressed air foam fire engines have different types, functions, and prices. The price is determined according to the configuration of the vehicle.
