What is an Alpha lubricator?

The Alpha ACC (Adaptive Cylinder Oil Control) is based on an algorithm controlling the cylinder oil dosage proportional to the sulfur content in the fuel.

What is ACC factor in Alpha lubricator?

mended ACC (Adaptive Cylinder oil Control) feed rate factors for plants land and Alpha Lubricator or ME Lube. equipped with Alpha Lubricator or ME Lube system.

What is cylinder lubricator?

Purpose. The basic purpose of the HJ Mechanical Cylinder Lubricator is to pump cylinder lube oil through the pressure tubes and into the cylinder lubrication valves lubricating the cylinder liner. The cylinder lubrication reduces the friction between the pistons and the cylinders, whereby the wear is reduced.

What is pulse lubrication?

What is Pulse Lubrication System? A pulse lubrication system is an electronically controlled cylinder oil lubrication system for Wartsila engines, wherein metered quantity of cylinder oil is injected in to the liner, depending on the engine load.

What is the function of alpha lubricator?

The oil fed to the injectors is pressurized by means of Alpha lubricator on each cylinder, equipped with small multi-piston pumps. The amount of oil fed to the injectors can be finely tuned with an adjusting screw, which limits the length of the piston stroke.

What is the purpose of cylinder oil?

Cylinder Lubrication system Cylinder lubrication is required in order to lubricate the piston rings to reduce friction between the rings and liner, to provide a seal between the rings and the liner, and to reduce corrosive wear by neutralising the acidity of the products of combustion.

What is the purpose of cylinder lubricant?

What is the purpose of using lubricant?

A lubricant is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.

What are different methods of lubrication?

There are three methods of lubricating LM systems: manual greasing using a grease gun or manual pump, forced greasing with the aid of an automatic pump, and oil-bath lubrication. To achieve efficient lubrication, it is necessary to mount the grease nipple or the plumbing fixture ac- cording to the mounting orientation.

How are 4 stroke engines lubricated?

Four-stroke engines are lubricated by oil held in an oil sump. The oil is distributed through the engine by splash lubrication or a pressurized lubrication pump system; these systems may be used alone or together. Splash lubrication is achieved by partly submerging the crankshaft in the oil sump.

Why are telescopic pipe used for oil lubrication?

Oil supply to the crosshead is via a telescopic pipe from the main LO supply at a pressure of about 2.5 bar. The grooves extend right to the edges of the bearing to ensure a flow of oil, thus cooling the bearing.

How does lubrication system with Alpha lubricators work?

Figure 2.1: Cylinder lubrication system with Alpha lubricators. A pump station delivers lube oil to the lubricators at 45 bar pressure. The lubricators have a small piston for each lube oil quill in the cylinder liner, and the power for injecting the oil comes from the 45 bar system pressure, acting on a larger common driving piston.

How is the Man b & w Alpha lubricator controlled?

The MAN B&W Alpha Cylinder Lubricator is preferably to be controlled in accordance with the Alpha Adaptive Cylinder oil Control (Alpha ACC) feed rate system. The MCU is equipped with a Backup Control Unit (BCU) which, if the MCU malfunctions, activates an alarm and takes control automatically or manually, via a Switch Board Unit.

Which is lubrication function is MEP dependent?

Lubricating control functions such as ‘mep dependent’ and ‘load change dependent’ are all incorporated in the MAN B&W Alpha cylinder lubrication system. The MAN B&W Alpha Cylinder Lubricator is preferably to be controlled in accordance with the Alpha Adaptive Cylinder oil Control (Alpha ACC) feed rate system.

Where is the Alpha cylinder lubricator control unit located?

The MCU, BCU and SBU together comprise the Alpha Cylinder Lubricator Control Unit (ALCU) in shape of a single steel cabinet which is, as standard, located in the Engine Control Room. ALPHA CYLINDER LUBRICATORS WITH PIPING AND INSTRUMENTS
