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.

All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements. The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. 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.
You gydrophore consider its working similar to that of below in your bathroom sink. 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 hydropnore the ring main. Close the vent and open the low pressure air supply valve. The engineering department produces documentation relevant to all phases of the project.
Avoid overcharging, otherwise air will came out of the taps with water. 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.
Fresh Water Hydrophore System in Ship – ShipFever
Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps. V sterilizer before consumption. Then when the air pressure is 4. Make sure the water is always visible through the gauge glass throught the operation. 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. Quick Charge the hydrophore tank sysyem to it reach 4.
Marine Pressure Hydrophore Tank
Once pumped it is discharged into hydrophore tank via pump discharge valve. Home Systems Hydrophore Systems. This means there is a leak in air supply line or the valve itself slowly filling tank with more and more air. Make sure that the pump cutoff at 5. 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.
Pressure in sysgem water vessel are maintained by an air cylinder rack with a booster pump that refills after each use. Water is stored in the hydrophore tanks situated in the engine room; It is eystem pressurized using compressed air from air bottle via pressure reducing valve. Once its at 4. At first fix this problem temporarily by crack open the vent valve and letting some air go.
The situation can be found with no water supply at the accommodation top.
Cover all sections of piping with a single system. But for long term solution you have to apply soap solution on all joints and key leak point.
Systfm normally includes the following: Most of you must be familiar with the water tanks on the top of our home or on street at quite some hight Huh? Have you ever imagined how fresh water is transported to all decks and places on ship? Make sure to watch that the pump cut-in and cutoff at the desired pressure next time.
Learn how your comment data is processed. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room. Documentation normally includes the following:. An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top.
Fresh Water Hydrophore System in Ship
These pumps are controlled by the pressure switches installed on hydrophore tanks. Once leak detected stop and DE-pressurize the system and rectify the fault.
This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself. Being under charged hydfophore one of the most common problem of hydrophore. This site uses Akismet to reduce spam. When the pressure inside the ssytem reduced to a certain value the pump start. Uydrophore board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line.
This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. In case of drinking fresh water system the output from hydrophore tank go through U. In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve.
It is this device which send signal to selector switch that pass on that hyrrophore to continue pumping to the selected pump.
Furthermore, the entire system also sysem all hydrphore and instrumentation necessary for standard operation, maintenance, and testing. 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. So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water.
The release and reset mechanisms for all parts of the hydrophore system are fully automatic. Open your air supply valve and pressurize tank up till 5. In long run prepare the system to be DE-pressurize; open air supply valve and overall it.
These pumps are operated based on the hydrophore pressure using pressure switch. Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps.
