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.

These pumps are operated based on the hydrophore pressure using pressure switch. It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump.
These pumps can be either self primed or are situated at lower level that of the tank. So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. 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.
Make sure the water is always visible through the gauge glass throught the operation. The engineering department produces documentation relevant to all phases of the project.
Most of you must be familiar with hydrophhore water tanks on the top of our home or on street at quite some hight Huh? Close the vent and open the low pressure air supply valve. In hydrophore system, a systej pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve.
But for long term solution you have to apply soap solution on all joints and key leak point. So we have domestic and drinking fresh hyxrophore system on board ship which utilize the pressure in hydrophore tanks to supply fresh water. Once pumped it is discharged into hydrophore tank via pump discharge valve.
This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. Now transfer the system on auto. There is a continues use of water on ship from drinking to sanitary purposes.
Make sure to watch that the pump cut-in and cutoff at the desired pressure next time. All design parameters of the Firenor hydrophore system can be customized hydrophofe needed in order to meet specific project requirements. In case of drinking fresh water system the output from hydrophore tank go through U. Gravity works as a source to supply water at desired pressure at all points. When a high flow firewater consumer starts before the fire water pumps, water is drained from the highest points of the ring main.
Open your air supply valve and pressurize tank up till 5. When the pressure inside the hydrophore reduced to a certain value the pump start. The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. Your email address will not be published. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use. Once its at 4. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room.
This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum from ever forming. At first fix this problem temporarily by crack open the vent valve and letting some air go. The release and reset mechanisms for all parts of the hydrophore system are fully automatic.
Learn how your comment data is processed. This is quite rare but possible problem you may face with hydrophore system. V sterilizer before consumption. This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself.
Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps. 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. Charging the hydrophore system is a simple process of adding more compressed air to pressurize the hydrophore tank. Home Systems Hydrophore Systems. This drain results in a vacuum in the upper levels of the ring main.
Fresh Water Hydrophore System in Ship
Once the pressure reach 4. Documentation normally includes the following:. You can consider its working similar to that of below in your bathroom sink. Have you ever imagined how fresh water is ststem to all decks and places on ship?
Marine Pressure Hydrophore Tank, Buy Pressure Water Tank from China Manufacturer – JINBO MARINE
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.
The water vessel for the Firenor hydrophore system has a standard water capacity that is capable of functioning hydrophoree up to 30 seconds, long enough to prevent pressure surges in standard fire protection systems. This means there is a leak in air supply line or the valve itself slowly filling tank with more and more air. These pumps are controlled by the pressure switches installed on hydrophore tanks.
V sterilizer and then to accommodation. Being under charged is one of the most common problem of hydrophore. Furthermore, the entire system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing. Documentation normally includes the following: This site uses Akismet to reduce spam.
Hydrophore – Wikipedia
Quick Charge the hydrophore tank up to it reach 4. In small ships or industries with small hydrophore the system may be required to cut in at 2. Cover all sections of piping with a single system.
