1, the fire features: fire pry block itself is an independent fire fighting unit, a separate diesel engine, fire pump and fire gun composition.
2, remote water supply: If a city a major fire in the vicinity of the scene and no fire hydrant or water supply shortage, the high-power remote water supply system can be kilometers away, or even further water pressure to continue, the first A time to transport the fire scene, for fire fighting, the device can use seawater, river water and lake water.
3, drainage features: high-power remote water supply system also has a drainage effect, when a major urban floods, the system can be the largest displacement, the fastest speed for the city drainage work, which has been confirmed in foreign countries.
The external fire fighting system (fi-fi system), is fully integrated with the vessel. Power source is very often the main engine to utilize the vacant power during station keeping and manoeuvring during fire fighting operations. The power is transferred to the pumps via remote operated clutch and necessary transmission.
On ships with fixed propellers a dedicated diesel driver or electrical or hydraulic driver may be used to avoid impact from ships operation to the fi-fi system.
The pumps are normally located in the engine room below water line for best possible performance via suction line design. They deliver water to the discharge pipe going all the way up to the monitor on top of the bridge or similar good position.
The water jet is created in the monitor outlet by pressing water at optimum speed trough the special designed monitor nozzle. The reaction force must be compensated by the vessel propulsion and manoeuvring system for station keeping.
