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.

On board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line.
Being under charged is one of the most common problem of hydrophore. This drain results in a vacuum in the upper levels of the ring main. Now transfer the system on auto. The engineering department produces documentation relevant to all phases of the project.
This means there is a leak in air supply line or the valve itself slowly filling tank with more and more air. These pumps can be either self primed or are situated at lower level that of the tank.
This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself. Gravity works as a source to supply water at desired pressure at all points. Now the pump will cut-in when the pressure reach 4. But for long term solution you have to apply soap solution on all joints and key leak point.
In long run prepare the system to be DE-pressurize; open air supply valve and overall it.
Documentation normally includes the following:. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room. This is quite rare but possible problem you xystem face with hydrophore system. When the pressure inside the hydrophore reduced to a certain value the pump start.
Quick Charge hydrophoer hydrophore tank up to it reach 4. Leave a Comment Cancel reply Your email address will not be published. Once leak detected stop and DE-pressurize the system and rectify the fault.
Fresh Water Hydrophore System in Ship
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.
The release and reset mechanisms for all parts of the hydrophore system are fully automatic. This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. 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. Most of you must be familiar with the water tanks on the top of our home or on street at quite some hight Huh?
At first fix this problem temporarily by crack open the vent valve and letting some air go. Then when the air pressure gydrophore 4.
Cover all sections of piping with a single system. An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top.
Open your air supply valve and pressurize tank up till 5. In small ships or industries with small hydrophore the system may be required to cut in at 2. These pumps are controlled by the pressure switches installed on hydrophore tanks. Home Systems Hydrophore Systems. Charging the hydrophore system is a simple process of adding more compressed air to pressurize the hydrophore tank.
V sterilizer before consumption. Hydropuore water is pumped in sjstem hydrophore tank to a certain limit; Low pressure compressed air is then introduced from the top at a pressure of 4. The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump.
V sterilizer and then to accommodation. Water is stored in the hydrophore tanks situated in the engine room; Systtem is then pressurized using compressed air from air bottle via pressure reducing valve. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass.
Documentation normally includes the following: So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water. Make sure the water is always visible through the gauge glass throught the operation. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use.
Your email address will not be published. Furthermore, the entire system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing. hydrophorre

Once pumped it is discharged into hydrophore tank via pump discharge valve. The output from the domestic fresh water hydrophote 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.
Once the pressure reach 4. The situation can be found with no water supply at the accommodation top. Syatem case of drinking fresh water system the output from hydrophore tank go through U.
Make sure that the pump cutoff at hydropyore. Learn how your comment data is processed. Avoid overcharging, otherwise air will came out of the taps with water.
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.
