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.

Gravity works as a source to supply water at desired pressure at all points. Then when the air pressure is 4. In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve. 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.
It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump. Cover all sections of piping with a single system.
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.
Quick Charge the hydrophore tank up to it reach 4. Open your air supply valve and pressurize tank up till 5. Documentation sysrem includes the following:.
Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps. Have you ever imagined how fresh water is transported to all decks and places on ship? The situation can be found with no water supply at the accommodation top. Being under charged is one of the most common problem of hydrophore. There is a continues use of water on ship from drinking hydophore sanitary purposes.
Most of you must be familiar with the water tanks on the top of our home or on street at quite some hight Huh? Make sure to watch that the pump cut-in and cutoff at the desired pressure next time. Make sure the water is always visible through the gauge glass throught the operation. When a high flow firewater consumer starts before the fire water pumps, water is drained from the hydfophore points of the ring main.
All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements.
The release and reset mechanisms for all parts of the hydrophore system are fully automatic.
Marine Pressure Hydrophore Tank, Buy Pressure Water Tank from China Manufacturer – JINBO MARINE
So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. Now transfer the system on auto. Make sure that the pump cutoff at 5. In long run prepare the system to be DE-pressurize; open air supply valve and overall it. So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water. This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure.
This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum from ever forming.

Close the vent and open the low pressure air supply valve. In case of drinking fresh water system the output from hydrophore tank go through U. Learn how your comment data is processed. Once its at 4. An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top.
The engineering department produces documentation relevant to all phases of the project. But for long term solution you have to apply soap solution on all joints and key leak point. These pumps are controlled by the pressure switches installed on hydrophore hydrophoore. This means there is a leak in air supply line or the valve itself slowly filling tank with more and more air.

Marine Pressure Hydrophore Tank
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. 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. Your email address will not be published. On board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line.
Hyxrophore first fix this problem temporarily by crack open the vent valve and letting some air go. But to charge the system manually; first open hydtophore vent, start the pump and watch the level through sight glass. Temporarily you can fix this problem by switching pump to systsm and drain the excess water or utilizing in engine room. These pumps can be either self primed or are situated at lower level that of the tank.
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. Once pumped it is discharged hydrophord hydrophore tank via systme discharge valve. This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself.
In small ships or industries with small hydrophore the system may be required to cut in at 2.
This drain results in a vacuum in the upper levels of the ring main. V sterilizer before consumption.
Fresh Water Hydrophore System in Ship
Home Systems Hydrophore Systems. Once the pressure reach 4. This is quite rare but possible problem you may face with hydrophore system.
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.
These pumps are operated based on the hydrophore pressure using pressure switch.
