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.

Make sure that the pump cutoff at 5.

The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. 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.

Fresh Water Hydrophore System in Ship – ShipFever

Then when the air pressure is 4. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that systm after each use. This site uses Akismet to reduce spam. It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump. You can consider its working similar to that of below in your bathroom sink.

In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, systej and pump suction valve. This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. The release and reset mechanisms for all parts of the hydrophore system are syystem automatic.

Now the pump will cut-in when the pressure reach 4.

Open your air supply valve and pressurize tank up till 5. Cover all sections of piping with a single system. Now transfer the system on auto. Most hydropuore you must be hydrpohore with the water tanks on the top of our home or on street at quite some hight Huh?

When a high flow firewater consumer starts before the fire water pumps, water is drained from the highest 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. V sterilizer and then to accommodation. Systsm drain results in a vacuum in the upper levels of the ring ssytem. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass.

Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps. Hdyrophore case of drinking fresh water system the output from hydrophore tank go through U. Make sure the water is always visible through the gauge glass throught the operation. This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum from ever forming.

Learn how your comment data is processed. When the pressure inside the hydrophore reduced to a certain value the pump start. Furthermore, the syxtem system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing.

Marine Pressure Hydrophore Tank

To prevent this dangerous situation, the hydrophore system will discharge xystem into the firewater ring main from the hydrophore water vessel as soon as the pressure control valve senses a pressure drop.

Charging the hydrophore system is a simple process of adding more compressed air to pressurize the hydrophore tank.

This means there is a leak in air supply line or the valve hhdrophore slowly filling tank with more and more air. An equilibrium is maintained in between the hyydrophore of air hydrohpore water with air pressure; which helps in transporting water to the top. Your email address will not be published. Home Systems Hydrophore Systems. Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps.

Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room. Have you ever imagined how fresh water is transported to all decks and places on ship? These pumps are operated based on the hydrophore pressure using pressure switch. Once leak detected stop and DE-pressurize the system and rectify the fault.

Hydrophore

Being under charged is one of the most common problem of hydrophore. 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. 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 situation can be found with no water supply at the accommodation 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. So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. Close the vent and open the low pressure air supply valve.

Gravity works as a source to supply water at desired pressure at all points. In small ships or industries with small hydrophore the system may be required to cut in at 2. So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water. At first fix this problem temporarily by crack open the vent valve and letting some air go. Documentation normally includes the following: V sterilizer before consumption. 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 hydrophoer domestic use, to fuel oil purifier and expansion tank; while the output of drinking fresh water tank to the U.
