Hydrophore System is an equipment used to maintain the water pressure provided to the multiple areas of the vessel at distinct heights in order to keep the continuous water presser in all lines and on all vessel floors. You Should read about fresh water generator. Hopefully,you understand that the demand for fresh water varies from the minimum freshwater consumption to the maximum in distinct areas of the vessel. If you use a centrifugal pump straight to the fresh water line, the pump will frequently cut in and cut off due mainly to low water consumption, which rapidly lowers system pressure.

This new electronically controlled hydrophore system incorporates state-of-the-art frequency drives, pumps and control technology to provide responsive and reliable water distribution for yachts. The use of variable frequency drives ensures smooth water pressure regulation, avoids any water hammer effects and greatly reduces the size of pressure reservoirs. Automatic rotation of lead pumps ensures even wear. In addition, several levels of redundancy ensure continuous system operation in the case of individual component failure.
HEM hydrophone systems always consist of a minimum of two independent pumps, each with its dedicated variable frequency drive. This means that the system will operate comfortably with only one pump running for most daily usage, the second pump being used as an assist pump in peak periods. In a duplex system two independent pump sets , the normal operating mode consists of a master pump and slave pump. The master pump controls the delivery pressure by varying the pump speed continuously according to a pressure feedback signal.
The slave pump can be programmed as a fixed-speed assist pump or as a speed controlled pump with a pressure setpoint lower than the master pump. The frequency controllers are programmed in such a way that each one can take over the master function should one controller fail. Each variable frequency drive has a dedicated redundant pressure transducer circuit and can individually control the system in case of emergencies.

An Easily Guide On Fresh Water Hydrophore System In Ship
If you charge more air pressure than required then its called overcharged If you charge less air pressure than required then its called undercharged. Further reason for continuous pump running is a leak in the system. Give a drop in system pressure which the pump will try to make up. Yea, leakage or huge consumption of water also leads to the continues running of the motor. Please Discuss below It is capable of performing an array of actions including pumping, storing and supplying fresh water at a regular ,controlled pressure in marine ships. Why hydrophore system is mandatory onboard?
A hydrophore system is used on a ship to maintain constant water pressure to all parts of a ship varying over different lengths and heights at all times without continuous pump operation. Based on their working medium it can be further classified into a freshwater hydrophore system and salinity water hydrophore system. Have you ever imagined how freshwater is transported to all decks and places on the ship? Do they use Pumps 24 hrs? Hydrophore system is used onboard to provide water to all compartments and decks on a ship.
