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.

Once the pressure reach 4. Quick Charge the hydrophore tank up to it reach 4. Once water is pumped in the hydrophore tank to a certain limit; Low pressure compressed air is then introduced from the yhdrophore at a pressure of 4.

Your email address will not be published. But for long term solution you have to apply soap solution on all joints and key leak point.


The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. This site uses Akismet to reduce spam. 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. These pumps can be either self primed or are situated at lower level that of the tank.

In case of drinking fresh water system the output from hydrophore tank go through U.

Marine Pressure Hydrophore Tank, Buy Pressure Water Tank from China Manufacturer – JINBO MARINE

The output from the domestic fresh water hydrophore tank is connected ssystem lines for domestic use, to fuel oil purifier and expansion tank; while the output of drinking fresh water tank to the U. This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum from ever forming. This drain results in hydrophkre vacuum in the upper levels of the ring main.


Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps.

Marine Pressure Hydrophore Tank

An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top. Once pumped it is discharged into hydrophore tank via pump discharge valve. These pumps are controlled by the pressure switches installed on hydrophore tanks. 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 ststem prevent pressure surges in standard fire hydroophore systems.

Once its at 4. In hydrophore system, a hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve. Open your air supply valve and pressurize tank up till 5. Cover all sections of piping with a single system.

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. You can consider its working similar to that of hydrophote in your bathroom sink. Furthermore, the entire system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing.

Sustem situation can be found with no water supply at the accommodation top. Now the pump will cut-in when the pressure reach 4. Charging the hydrophore system is gydrophore simple process of adding more compressed air to pressurize the hydrophore tank.

This is quite rare but possible problem you may face with hydrophore system. On board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line.


Documentation normally hyddophore the following:. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass. Then when the air pressure is 4. Now transfer the system on auto. Close the vent and open the low pressure air supply valve.

It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump. The release and reset mechanisms for all parts of the hydrophore system are fully automatic. Make sure to watch that the pump cut-in and cutoff at the desired pressure next time. When the pressure inside the hydrophore reduced to a certain value the pump start.

Have you ever imagined how fresh water is transported to all decks and places on ship? All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements. Once leak hydrophors stop and DE-pressurize the system and rectify the fault. 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.

Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps. Make sure that the pump cutoff at 5.
