Aluminum Alloy water foam Monitor system settings

General provisions

Water supply pipelines should be separated from production and domestic water pipelines.

The water supply pipeline should not be used together with the supply pipeline of the foam mixture. Wet water supply pipes in cold regions should take antifreeze protection measures, and dry pipes should be equipped with facilities to remove water and air in the pipes. The pipeline design shall meet the design flow rate, pressure and the time from opening to injection.

The capacity of the fire-fighting water source should not be less than the sum of the water consumption required to use water cannons, foam cannons, protective water curtain nozzles, etc. at the same time during the specified fire extinguishing time and cooling time and the water filling volume in the water supply pipeline. This capacity may be subtracted from the supplementary water quantity during the specified fire extinguishing time and cooling time.

The water supply pressure of the fire pump should meet the requirements of the spray pressure of water cannon and foam cannon in the system.

The supply time of fire extinguishing agent and pressurized gas should not be longer than 48h.

Aluminum Alloy water foam Monitor of The time from the start of the water monitor system and the foam monitor system to the spraying of water or foam by the foam should not exceed 5 minutes, and the time from the start of the dry powder monitor system to the spraying of dry powder from the nozzle should not be greater than 2 minutes.

Fire Monitor Arrangement

The number of indoor fire monitors should not be less than two, and the height of the arrangement should ensure that the jets of the fire monitors will not be affected by the structural parts of the upper building, and the water jets of the two water monitors should reach any part of the protected area at the same time. part.

The indoor system shall adopt a wet water supply system, and the fire pump start button shall be set at the fire monitor position.

When setting up the fire monitor platform, its structural strength should be able to meet the requirements of the jet reaction force of the fire monitor, and the structural design should be able to meet the normal use requirements of the fire monitor.

The layout of the outdoor fire monitors should enable the jets of the fire monitors to completely cover the protected places and protected objects, and should meet the requirements of fire extinguishing intensity and cooling intensity.

Fire monitors should be installed in the upwind direction of the perennial dominant wind direction in the protected place;

When the height of the fire extinguishing object is high and the area is large, or when the jet flow of the fire monitor is blocked by tall obstacles, a fire turret should be installed.
