What is Distillate pump?

The distillation pump is used in the thermal separation process to convey the more volatile medium at the column head. Depending on the application, the distillate can be the valuable material itself or a solvent that is to be fed back into the process and reused.

What type of pump is commonly used on distillate water pump?

A distillate pump is a normal centrifugal pump located at the lower most part of the fresh water generator. It takes suction from the steam condensate; and discharge to the drinking water tank on ship. The output pass through a salinometer which checks for the salt content in the output water.

What is distillate pump in fresh water generator?

Distillate pump help to pump out the freshwater from condenser and seawater pump supply sea water to condenser and evaporator. > Demister: Demister help to remove the carry over of sea water droplets and water spray. It is made of layered knitted wire of monel metal.

What is FWG explain basic principle?

Fresh Water Generator Working Principle. Basic principle of all low pressure freshwater generator is that, boiling point of water can be reduced by reducing the pressure of the atmosphere surrounding it. The source of heat for the fresh water generator could be waste heat rejected by main engine jacket cooling water.

What is sea water pump?

Sea water pumps are used to transfer or circulate seawater for various applications on board a marine vessel. The wide range of uses of a seawater service pump includes anything from ballast transfer to bilge pumping and firefighting to high-pressure deck washing.

How does a salinometer work?

A salinometer is a device that is used to determine the salinity of water. A salinometer generally works by passing an electric current through any known mass of water. Since salt water conducts electricity much more easily than pure water the salinity content of water can be easily calculated.

What type of pump is used in fresh water generator?

The freshwater Generator, type AFGU 2SA, is supplied with a separate ejector pump supplying sea feed water and sea water to the ejectors from a separate sea-water intake. – The condenser is supplied with water from the main cooling water system.

What is the ppm of fresh water generator?

Reliable production of high-quality fresh water AQUA Blue freshwater generators provide a continuous supply of low-salinity (below 2 ppm) fresh water on board, which is more convenient and economical than bunkering water.

What is the function and uses of FWG?

Answer: A Fresh Water Generator Is Equipment Used Onboard For Production Of Fresh Water From Sea Water. It Also Serves The Purpose Of Cooling The Hot Jacket Cooling Water At Around 85 Deg Celsius To 65 Deg Celsius.

What is salinity alarm in evaporator?

Applications. Fresh water generators (Evaporators) use salinometers on the distillate discharge in order to gauge the quality of the water. In these ships, a salinometer is also installed on the feed system where it would alert the engineer to any salt contamination.

What is the use of main sea water pump?

A sea water pump provides greater flow of the water and is perfect for low viscosity liquid like the sea water. These devices are used to circulate sea water for various applications on board a ship.

How distillate pumps work?

Distillate pump get maximum net positive suction head with the height of liquid column in the suction line. Thermometers are installed for control of seawater to the condenser and jacket cooling water to the evaporator. These thermometers permit control of both heating and cooling of these units.

How does the distillation of fresh water work?

It uses heat passing through submerged coils or tube bundles immersed in sea water to produce the distillate, which when condensed becomes the fresh water. it consist of two parts

What is vacuum distillation process?

VACCUME DISTILLATION PROCESS. vacuum distillation is the process use to convert sea water in to fresh water. by this process constant supply of fresh water with low salinity level and be achieved with continuous controlling the water quantity. WORKING PRINCIPAL . 0feed water enter in to the lower section of the plate packs.

How does a single-stage centrifugal fresh water pump work?

The single-stage centrifugal fresh water pump extracts the distillate from the condenser and pumps it to the fresh water tank. The pump is fitted after the suction of low sea chest. because at the low sea chest suction there is no oil present .and is the best point of taking the main sea water suction .
