Fire hydrant system is the most commonly used fire fighting system, and also the most basic fire extinguishing system. Fire hydrant network of the most adverse point, water pressure needs to remain at 3Mpa pressure above, usually pipe water pressure by the fire hydrant pressure regulating pump for voltage regulation.
