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.

Water is stored in hydrophor hydrophore tanks situated in the engine room; It is then pressurized using compressed air from air bottle via pressure reducing valve. Most of you must be familiar with the water tanks on the top of our home or on street at quite some hight Huh?
Close the vent and open the low pressure hydropyore supply valve. It is this device which send signal to selector switch that pass on that signal to continue pumping to the selected pump.
Marine Pressure Hydrophore Tank, Buy Pressure Water Tank from China Manufacturer – JINBO MARINE
Being under charged is one of the most common problem of hydrophore. At first fix this problem temporarily by crack open the vent valve and letting some air go. These pumps can be either self primed or are situated at lower level hydrophoe of the tank. In small ships or industries with small hydrophore the system may be required to cut in at 2.

Furthermore, the entire system also includes all valves and instrumentation necessary sysgem standard operation, maintenance, and testing. V sterilizer and then to accommodation. Now transfer the system on auto. 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 operated based on the hydrophore pressure using pressure switch. Fresh water from the domestic fresh water tank is pumped to the hydrophore tank through any of the two pumps. So we have domestic and drinking fresh water system on board ship hydrophlre utilize the pressure in hydrophore tanks to supply fresh water.
Once the pressure reach 4.
Pressure in the water vessel are maintained by an air hydrophofe rack with a booster pump that refills after each use. This is quite rare but possible problem you may face with hydrophore system.
Your email address will not be published. So to reduce unnecessary power consumption and maintenance costs for pumps; hydrophore system are installed on ship. This pressure switch on the hydrophore tank hudrophore a below that expands and contract based on hydrophore tank pressure. When a high flow firewater consumer starts before the fire water pumps, water is drained from the highest points of the ring main. There is a continues use of water on ship from drinking to sanitary purposes.
The situation can result into no water in hydrophore tank in some cases sgstem thus be reacted quickly with care.
This site uses Akismet to reduce spam. 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. These pumps are controlled by the pressure switches installed on hydrophore tanks. This means air is leaking from either; relief valve, isolation valve, hyddophore supply valve, vent valve or the gauge ststem itself.
Have you ever imagined how fresh water is transported to all decks and places on ship?
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 to prevent pressure surges in standard fire protection systems.
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. Quick Charge the hydrophore tank up to it reach 4. Gravity works as a source to supply water at desired pressure at all points.
The release and reset mechanisms for all parts of the hydrophore system are fully automatic. Learn how your comment data is processed.
This drain results in a vacuum in the upper levels of the ring main. Now the pump will cut-in when the pressure reach 4. Documentation normally 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.
