foam proportioning system working principle

Fire truck tank baffles work on the principles of slosh suppression and energy dissipation in fluid mechanics. When a fire truck accelerates, brakes, or turns during driving, the water inside the tank generates severe sloshing forces. By installing perforated partitions inside the tank, baffles divide the large water volume into multiple smaller compartments. The orifice throttling effect dissipat...

A foam fire truck is a specialized firefighting vehicle designed to transport, mix, and discharge water and foam extinguishing agents for efficient fire suppression. Unlike standard fire trucks that rely primarily on water, foam fire trucks are equipped with a dedicated foam system that mixes water and foam concentrate at a preset ratio to form foam solution. A foam fire truck can discharge water ...
