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. Once the pressure reach 4. This is quite rare hhdrophore possible problem you may face with hydrophore system. Then when the air pressure is 4. In long run prepare the system to be DE-pressurize; open air supply valve and overall it.
Once water is pumped in the hydrophors tank to a certain limit; Low pressure compressed air is then introduced from the top at a pressure of 4. Documentation normally includes the following: These pumps can be either self primed or are situated at lower level that of the tank.
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.
This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass.
Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use. This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure.
There is a continues use of water on ship from drinking to sanitary purposes.
V sterilizer and then to accommodation. All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements.
This means there is a leak in air hydriphore line or the valve itself slowly filling tank hydrophord more and more air. Most of you must be familiar with the water tanks on the top of our home or on street at quite some hight Huh?
When the pressure inside the hydrophore reduced to a certain value the pump start. In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve.
These pumps are controlled by the pressure switches installed on hydrophore tanks.
Marine Pressure Hydrophore Tank, Buy Pressure Water Tank from China Manufacturer – JINBO MARINE
Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps. Furthermore, the entire system also includes all valves and hydrophre necessary for standard operation, maintenance, and testing. Cover all sections of sysem with a single system. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room. 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. In case of drinking fresh water system the output from hydrophore tank go through U.
Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps.
So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water. Your email address will not be published.
An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top. But for long term solution you have to apply soap solution on all joints and key leak point. It is this hydeophore which send signal to selector switch that pass on yydrophore signal to continue pumping to the selected pump.
The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. On board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line.

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. This drain results in a vacuum in the upper levels of the ring main.
Have you ever imagined how fresh water is hyrophore to all decks and places on ship? Once its at 4. Gravity works as a source to supply water at desired pressure at all points. Make sure the water is always visible through the gauge glass throught the operation. Home Systems Hydrophore Systems. Make sure to watch that the pump cut-in and cutoff at the desired pressure next time.
In small ships or industries with small hydrophore the system may be required to cut in at 2.
