A hydrophore can refer to: Hydrophore (sampling), a scientific instrument for obtaining samples of water from a body of water from any desired depth; Hydrophore (system) [nl]. This new electronically controlled hydrophore system incorporates state of the art frequency drives, pumps and control technology. Why hydrophore system is mandatory onboard? Hope you know that the demand of freshwater is different in different parts of the ship ranging from minimum.

So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship.

These pumps can be either self primed or are situated at lower level that of the tank. An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top.

Make sure to watch that the pump cut-in and cutoff at the desired pressure next time. This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself. Once the pressure reach 4.

The Firenor hydrophore system is a safety system designed to prevent pressure surges in the firewater distribution piping that occur when a deluge system or any other water consuming systems release water before fire water pumps are up and running.

The water vessel for the Firenor hydrophore system has a standard water capacity that is capable of functioning for up to 30 seconds, long enough to prevent pressure surges in standard fire protection systems.

V sterilizer before consumption.

Marine Pressure Hydrophore Tank

Open your air supply valve and pressurize tank up till 5. The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. Being under charged is one of the most common problem of hydrophore. The situation can be found with no water supply at the accommodation top. Now transfer the system on auto.


You can consider its working similar to that of below in your bathroom sink. All design parameters nydrophore the Firenor hydrophore system can be customized as needed in order to syste, specific project requirements. There is a continues use of water on ship from drinking to sanitary purposes.

The engineering department produces documentation relevant to all phases of the project. Home Systems Hydrophore Systems. In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room.

This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. Most of you must be familiar with the water tanks on the top of our home or on street at quite some hight Huh?

Furthermore, the entire system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing. This drain results in a vacuum in the upper levels of the ring main. Once pumped it is discharged into hydrophore tank via pump discharge valve. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use.

Avoid overcharging, otherwise air will came out of the taps with water. Now the pump will cut-in when the pressure reach 4. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass. Make sure the water is always visible through the gauge glass throught the operation.

Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps. This means there is a leak in air supply line or the valve itself slowly filling tank with more and more air.

What is a Hydrophore System ? | Marine Notes

This is quite rare but possible problem you may face with hydrophore system. Leave a Comment Cancel reply Your email address will not be published. Documentation normally includes the following: In case of drinking fresh water system the output from hydrophore tank go through U.


Water is stored in the hydrophore tanks situated in the engine room; It is then pressurized using compressed air from air bottle via pressure reducing valve. The release and reset mechanisms for all parts of the hydrophore system are fully automatic. So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water. These pumps are controlled by the pressure switches installed on hydrophore tanks. Gravity works as a source to supply water at desired pressure at all points.

When a high flow firewater consumer starts before the fire water pumps, water is drained from the highest points of the ring main. Close the vent and open the low pressure air supply valve.

In small ships hydrophoge industries with small hydrophore the system may be required to cut in at 2. But for long term solution you have to apply soap solution on all joints and key leak point.

Documentation normally includes the following:. To prevent this dangerous situation, the hydrophore system will discharge water into the firewater ring main from the systeem water vessel as soon as the pressure control valve senses a pressure drop. At first fix this problem temporarily by crack open the vent valve and letting some air go.

Uydrophore water is pumped in the hydrophore tank to a certain limit; Low pressure compressed air is then introduced from the top at a pressure of 4. Once leak detected stop and DE-pressurize the system and rectify the fault.

Cover all sections of piping with a single system.
