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.

Then when the air pressure is 4. This drain results in a vacuum in the upper levels of the ring main. Quick Charge the hydrophore tank up to it reach 4.
So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room. Once the pressure reach 4. 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. Close the vent and open the low pressure air supply valve.
On board ship there is a separate hydrophore tank and supply line for drinking water known as drinking fresh water line. The engineering department produces documentation relevant to all phases of the project.
In long run prepare the system to be DE-pressurize; open air supply valve and overall it.

Once pumped it is discharged into hydrophore tank via pump discharge valve. Have you ever imagined how fresh water is transported to all decks and places sjstem ship? You can consider its working similar to that of below in your bathroom sink.
When the pressure hyvrophore the hydrophore reduced to a certain value the pump start. Documentation sgstem includes the following:. 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.
Learn how your comment data is processed. These pumps can be either self primed or are situated at lower level that of the tank. Avoid overcharging, otherwise air will came out of the taps with water.
Documentation normally includes the following: This means air is leaking from either; relief valve, isolation valve, air supply valve, vent valve or wystem gauge glass itself. In small ships or industries with small hydrophore the system may be required to cut in at 2. So we have domestic and drinking fresh water system on board ship which utilize the pressure in hydrophore tanks to supply fresh water.
This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum from ever forming.
These pumps are controlled by the pressure switches installed on hydrophore tanks. 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.
Open your air supply valve and pressurize tank up till 5. 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.
The situation can result into no water in hydrophore tank in some cases and thus be reacted quickly with care. Furthermore, the entire system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing. An equilibrium is maintained in between the levels of air and water with air pressure; which helps in transporting water to the top.
There is a continues use of water on ship from drinking to sanitary purposes. But for long term solution you have to apply soap solution on all joints and key leak point. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills hhydrophore each use. When hydrophlre high flow firewater consumer starts before the fire water pumps, water is drained from the highest points of the ring main.
Charging the hydrophore system is a simple process of adding more compressed air to pressurize the hydrophore tank. V sterilizer and then to accommodation. Make sure that the pump cutoff at 5.
This pressure switch on the hydrophore tank contains a below that expands and contract based on hydrophore tank pressure. This means there is a leak in air supply line or the valve itself slowly filling tank with more and more air. The situation can be found with no water supply at the accommodation top. Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophoree pumps.
Make sure the water is always visible through the gauge glass throught the operation. In hydrophore system, sysstem hydrophore pump Centrifugal takes suction from the fresh water tank through tank outlet valve, non-return and pump suction valve. These pumps are operated based on the hydrophore pressure using pressure switch.

Your email address will not be published. Home Systems Hydrophore Systems. Fresh water from the domestic fresh water tank is pumped hhdrophore the hydrophore tank through any of the two pumps.
At first fix this problem temporarily by crack open the vent valve and letting some air go. Gravity works as a source to supply water at desired pressure at all points. Leave a Comment Cancel reply Your email address will not be published. But to charge the system manually; first open the vent, start the pump and watch the syztem through sight glass.
