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.

This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. Then when the air pressure is 4. Open your air supply valve and pressurize tank up till 5.

Hydrophore System – TEHO Water & Envirotec Pte Ltd

This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself. The situation can be found with no water supply at the accommodation top. Cover all sections of piping with a single system. Now the pump will cut-in when the pressure reach 4. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use.

So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. Charging the hydrophore system is a simple process of adding more compressed air to pressurize the hydrophore tank. Make sure the water is always visible through the gauge glass throught the operation. Once leak detected stop and DE-pressurize the system and syetem the fault. Hydrphore prevent this dangerous situation, the hydrophore system will discharge water into the firewater ring main from hydorphore hydrophore water vessel as soon as the pressure control valve senses a pressure drop.

Have you ever imagined how fresh water is transported to all decks and places on ship? At first fix this problem temporarily by crack open the vent valve and letting some air go. Leave a Comment Cancel reply Your email address will not be published. Being under charged is one of the most common problem of hydrophore. Home Systems Hydrophore Systems. In long run prepare the system to be DE-pressurize; open air supply valve and overall it. In small ships or industries systen small hhydrophore the system may be required to cut in at 2.


Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps. V sterilizer and then to accommodation.

Marine Pressure Hydrophore 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 systm surges in standard fire protection systems. There is a continues use of water on ship from drinking to sanitary purposes. Most of you must be familiar with the water tanks on the top of our home or on street at quite gydrophore hight Huh?

Make sure that the pump cutoff at 5.

This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum hydrpohore ever forming. When a high flow firewater consumer starts before the fire water pumps, water is yhdrophore from the highest points of the ring main. Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps. On board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line.

It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump.

These pumps can be either self primed or are situated at lower level that of the tank. These pumps are controlled by the pressure switches installed on hydrophore tanks. 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 syshem U.


Once its at 4. The situation hhydrophore result into no water in hydrophore tank in some cases and thus be reacted quickly with care.

Hydrophore – Wikipedia

You can consider its working similar to that of below in your bathroom sink. All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements. An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top.

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. Your email address will not be published. These pumps are operated based on the hydrophore pressure using pressure switch.

Fresh Water Hydrophore System in Ship

Learn how your comment data is processed. Close the vent and open the low pressure air supply 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.

Make sure to watch that the pump cut-in and cutoff at the desired pressure next time. Gravity works as a source shstem supply water at desired pressure at all points.

Quick Charge the hydrophore tank up to it reach 4. The release and reset mechanisms for all parts of the hydrophore system are fully automatic. Documentation normally includes the following:.

Now transfer the system on auto. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass. The engineering department produces documentation relevant to all phases of the project. V sterilizer before consumption.
