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.

The release and reset mechanisms for all parts of the hydrophore system are fully automatic. Documentation normally includes the following: Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use.

When the pressure inside the hydrophore reduced to a certain value the pump start.

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. Make sure that the pump cutoff at 5. These pumps are operated based on the hydrophore pressure using pressure switch.

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. Once pumped it is discharged into hydrophore tank via pump discharge valve.

Charging the hydrophore system is a simple process of adding more compressed air to pressurize the hydrophore tank. This drain results in a vacuum in the upper levels hyydrophore the ring main. Most of you must be familiar with the water tanks on the top of our home or on street at quite some hight Huh?

The engineering department produces documentation relevant to all phases of the project. This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. Gravity works as a source to supply water at desired pressure at all points. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room.

At first fix this problem temporarily by crack open the vent valve and letting some air go. This means air is leaking from either; relief valve, isolation valve, wystem supply valve, vent valve or the gauge glass itself. Home Systems Hydrophore Systems. Now the pump will cut-in when the pressure reach 4. All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements.

V sterilizer and then to accommodation. On board ship there is hydropgore separate hydrophore tank and supply line for drinking water known as drinking fresh water line. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass.

Marine Pressure Hydrophore Tank

Now transfer the system on auto. This site uses Akismet to reduce spam. Your email address will not be published. The situation can be found with no water supply at the accommodation top.

Hydrophore – Wikipedia

hydropohre Once leak detected stop and DE-pressurize the system and rectify the fault. These pumps are controlled by the pressure switches installed on hydrophore tanks. Open your air supply valve and pressurize tank up till 5. This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum from ever forming.


Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of hydrlphore two pumps. There is a continues use of water on ship from drinking to sanitary purposes. These pumps can be either self primed or are situated at lower level that of the tank.

What is a Hydrophore System ? | Marine Notes

Avoid overcharging, otherwise air will came out of the taps with water. An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to systsm top.

The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps. Being under charged is one of the most common problem of hydrophore. So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. In long run prepare the system to be DE-pressurize; open air supply valve and overall it.

Fresh Water Hydrophore System in Ship

Learn how your comment data is processed. In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve.

So we have domestic and hydropuore fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water. You can consider its working similar to that of below in your bathroom sink. Furthermore, the entire system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing.
