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.

In small ships or industries with small hydrophore the system may be required to cut in at 2. When a high flow sysem consumer starts before the fire water pumps, water is drained from the highest points of the ring main. When the pressure inside the hydrophore reduced to a certain value the pump start.

Fresh water from the domestic hhydrophore water tank is pumped to the hydrophore tank through any of the two pumps.

Marine Pressure Hydrophore Tank, Buy Pressure Water Tank from China Manufacturer – JINBO MARINE

Once pumped it is discharged into hydrophore tank via pump discharge valve. In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve.

Being under charged is one of the most common problem of hydrophore. The situation can be found with no water supply at systek accommodation top. At first fix this problem temporarily by crack open the vent valve and letting some air go.

Now transfer the system on auto. Once 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. This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank xystem.

Learn how your comment data is processed. Open your air supply valve and pressurize tank up till 5. Have you ever imagined how fresh water is transported to all decks and places on ship?

Now the pump will cut-in when the pressure reach 4. In long run prepare the system to be DE-pressurize; open air supply valve and overall it.

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. So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water.

Make sure to watch that the pump cut-in and cutoff at the desired pressure next time. It is this device which send signal to selector switch hydgophore pass on that signal to continue pumping to the selected pump. Water is stored in the hydrophore tanks situated in the engine room; It is then pressurized hydrohpore compressed air from air bottle via pressure reducing valve. V systme before consumption. Avoid overcharging, otherwise air will came out of the taps with water.

Home Systems Hydrophore Systems. In case of drinking fresh water system the output from hydrophore tank go hyfrophore U. Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps.

The release and reset mechanisms for all parts of the hydrophore system are fully automatic. Make sure that the pump cutoff at 5. Then when the air pressure is 4.

This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself. On board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line. To prevent this dangerous situation, the hydrophore system will discharge water into the firewater ring main from the hydrophore water vessel as soon as the pressure control valve senses a pressure drop.

Documentation normally hycrophore the following: These pumps can be either self primed or are situated at lower level that of the tank.


You can consider its working similar to that of below in your bathroom sink. 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.

These pumps are controlled by the pressure switches installed on hydrophore tanks. The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. V sterilizer and then to accommodation. Close the vent and open the low pressure hydrophoge supply valve. The output from the domestic fresh water hydrophore tank is connected to lines for domestic use, to fuel oil purifier and expansion tank; while the output of drinking fresh water tank to the U.

This means hydfophore is a leak in air supply line or the valve itself slowly filling tank with more and more air. The engineering department produces documentation relevant to all phases of the project.

Fresh Water Hydrophore System in Ship

So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. Furthermore, the entire system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing.

There is a continues use of water on ship from drinking to sanitary purposes. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room.

Gravity works as a source to supply hydropbore at desired pressure at all points. Documentation normally includes the following:. All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements.
