The pressure inside the hydrophore is below the rated pressure range and is called under charged condition. obviously system capacity will get reduced and if you pressurize with large volume of air a large volume of water will be required to change the pressure in the system which may leads to late pump cut-in and losing of the pump suction.. Further reason for continuous pump running is a leak in the system. By contrast, the air pushes out water when water is drained and the pressure slowly decreases until the pumps kick in again. If hydrophore pumps are running more than usual, then there is a high possibility of: Being under charge is one of the most common problem of hydrophore. It is used in buildings, flats, detached villas, estates or high-rise buildings in cases where the mains water pressure is not sufficient to meet the pressurized water need. The pump will stop at the desired set pressure and then charging will stop.

Why Does the Hydrophore Fail? 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. In the hydrophore system, a hydrophore pump (Centrifugal) takes suction from the freshwater tank through the tank outlet valve, non-return, and pump suction valve. The crew consumes an average 100 liter/head/day. Water is almost incompressible so when it raises it compresses the air above. In this condition, the water level is more than 3/4 parts of the volume. Its not a big issue and generally taken care at the time of planned maintenance. Manometer; pressure is the name given to the reader. If pump making sound , better dismantle , inspect the bearings etc. i dont understand your question. >Start the hydrophor pump in manual mode & keep an eye on the side glass . 1.

Once the sight glass is filled with 70% of water, then charge the tank with compressed air and put the system in automatic. Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps. Avoid overcharging, otherwise air will came out of the taps with water. The pump builds up water in the tank and when the pressure hits the maximum(aprox 4.5bar) set pressure, it will cut off by the pressure switch.
when the pressure reaches 4.5 bar during charging,why do we need to reduce the charging pressure? That is why hydrophore tanks are charged with air to generate pressure on water.

Further, the charge air is nothing but the compressed air filled into the tanks from the air bottle via a pressure reducing valve to maintain equilibrium in between the levels of air and water; thus resulting in continues and good flow of water to all parts of the ship or any industry using hydrophore tanks. Importance of Bearing Selection in Pumps. Generally the hydrophore tank is under auto mode; which controls the cut-in and cut-out pressure of hydrophore pumps. Once the water level reach the 3/4th of the tank volume crack open the air supply line to charge it with compress air. What Should Be Considered During Pump Installation and Selection? At first fix this problem temporarily by crack open the vent valve and letting some air go. It is here we need to discuss about the role of Hydrophore. So we have domestic and drinking freshwater system onboard ship which utilize the pressure in hydrophore tanks to supply fresh water. Why hydeophore system is mandatory onboard?? What will happen when vacuum reach 100% in fresh water generator? Close the vents and open the valve for the supply of low pressure air. But to charge the system manually; first open the vent, start the pump and watch the level through sight glass. The system is mostly automated with the pressure switches controlling the pump cut in and cut out while the solenoid-operated air charge valves helps regulate air pressure. If the water is consumed ,then the air pressure will drop; a pressure switch is connected to the tank so that whenever the air pressure falls below the set pressure, (aprox 2.5bar) it will start the pump. Hydrophore tank is a pressurized vessel that is used for drinking or technical water supply in situations when the pressure in the pipeline is low. Systems like the main fire line, sprinkler systems and even fresh water systems are using a hydrophore to get around this. This cookie is set by GDPR Cookie Consent plugin. Hopefully, you understand that the demand for fresh water varies from the minimum freshwater consumption to the maximum in distinct areas of the vessel. Make sure that the pump cutoff at 5.5 bar otherwise the system need immediate maintenance. This cushion decreases as water absorbs air and the tank loses its ability to pressurize the system. You have to either run your pumps full time ( not possible ) or make water tanks on top of accommodation block ( just like we have in our homes ). Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. In small ships or industries with small hydrophore the system may be required to cut in at 2.5 bar and cut out at 4.5 bar.
