What is the use of fuel oil purifier?

Treatment of fuel oils and lubricating oils: Both fuel oils and lubricating oils require treatment before passing to the engine. The separation of impurities and water from fuel oil is essential for good combustion.

How does a fuel oil purifier work?

An oil purifier uses the same principle for separating dirt or water from oil. Instead of using gravity, it uses centrifugal force. Through a system of gears, a centrifuge bowl is rotated at high speeds. Oil to be purified is allowed to enter the bowl while it is rotating.

How do you stop the oil from the fuel purifier?

Stopping of Purifiers:

1. De-sludge the purifier after stopping the feed inlet.
2. Shut down the steam inlet to the oil.
3. Stop the purifier after filling up the bowl with water.
4. Apply brakes and bring up the purifier to complete rest.

What are the parts of fuel oil purifier?

The main component of purifier is correct size gravity disc or dam ring which is responsible for creating an interface between the oil and water. 2) Clarifier: When a centrifugal is arranged to remove only impurities and a small amount of water, it is called as the clarifier.

What is back pressure in purifier?

A pressure downstream (outlet side) of the filter that creates resistance to flow of liquid or gas. This can result from closing a valve or entrapped air in a liquid system. This can also result from gradual blocking of the filter during use or to the resistance to flow caused by the filter itself.

What is difference between purifier and clarifier?

The key difference between purifier and clarifier is that the purifier consists of a dam ring to create a line of separation between fuel and water whereas the clarifier consists of a sealing ring to prevent the fuel tank from water and dissolved impurities.

What are the types of purifier?

Depending on the water purification methods water purifiers are can be classified into 5 types.

• Reverse Osmosis(RO)
• Ultraviolet(UV)
• UltraFiltration(UF)
• Activated Carbon.
• Sediment filter.

What is friction clutch in purifier?

Purifier Drive: FRICTION CLUTCH ARRANGEMENT. It consist of a Friction Drum mounted on the horizontal shaft. 3 Friction Pads are mounted on the motor shaft, which are contained within the Friction Drum. Friction pads have a curved surface with Ferodo lining.

What is sealing water in purifier?

Why need sealing water? To seal the water outlet & to prevent the overflow of oil from the water outlet.

What will be the most probable consequences when there is no purifier on board ships?

If the break is not released, the purifier will not reach its required speed and the motor current will increase. Moreover, this will also cause wear down of brakes.

What are the common faults of a running purifier?

Purifier Problems: 6 Most Common and Their Solution

• Bowl Speed Low.
• Feed Pressure Low.
• Bowl not closing or leaking.
• High Water Content.
• Low Back Pressure.
• Oil Temperature High.

What is top disc in purifier?

Gravity disc which determines the interface between the two liquids is present in purifier whereas there is no gravity disc in a clarifier, instead there is a discharge collar which seals water outlet. A top disc with neck separates the oil and water passage in purifier.

What is paring disc in purifier?

What is paring disc? It is a stationary impeller mounted in a chamber at the neck of the bow. Its function is to convert the rotating energy of the liquid into a pressure head.
