What is lubrication system? Types of lubrication systems.

Lubrication scheme is used to add oil and other lubricants to provide an precise temperature stream to the smooth oil with adequate stress on moving components of the device. The oil is taken out of the sump into the pump, thus decreasing the friction between components and thus improving the longevity of all components. Most devices would be overheated or experience severe harm without lubrication.

The most significant element of machine and car life is proper lubrication. A well-oiled car will readily outlast designs that are poorly kept. Industrial equipment is the same, and long-term savings can be helped by a nice lubrication scheme.

The different types of lubrication systems used are 

1. Mist lubrication system 

2. Wet sump lubrication system, and 

3. Dry sump lubrication system

1. Mist lubrication system:

A tiny amount of lubricating oil is blended with a gas (mostly petrol) in this scheme. The carburetor introduces the oil and fuel mixture. The petrol is vaporized and the mist-shaped oil reaches the cylinder via the foundation of the crank. The oil bubbles hit the foundation of the crank, lubricate the primary and connecting rod bearings and the piston, piston rings and cylinder are lubricated by the remainder of the oil. In two-stroke engines where crank base lubrication is not needed, the scheme is favored. The fuel is partly squeezed in a crank tank in a two-stroke engine, so it is not ##s to have the oil in the core of the crank.

The various advantages are:

No oil changes and reduced maintenance requirements

Reduced lubricant consumption (up to 70 percent compared to sump lubrication)

Lower friction and reduced bearing temperatures

Mist delivery pressure blocks entrance of contaminants

Less wear and increased life of machine elements

Lower capital costs

This system is simple, low cost and maintenance free because it does not require any oil pump, filter, etc. However, it has certain serious disadvantages.

2. Wet-sump lubrication system:

This scheme comprises of a big oil storage capability at the crank chamber foundation. The pump draws the oil from the sump and applies it to different components of the engine. Excess oil will gradually return to the sump after fulfilling the purpose.

There are three varieties in wet-sump lubrication system. They are:
1. Splash lubrication system
2. Splash and pressure system and
3. Pressurized lubrication system

2.1 Splash Lubrication System:

In foam lubrication, by swinging dippers on the connecting-rod bearing caps, oil is added to the cylinders and pistons. The dippers move through an oil-filled trough every moment they rotate. The dippers pour oil onto the cylinders and pistons to lubricate them after passing through the oil trough.

While for larger motors and pumps, splash lubrication is efficient, it is not an accurate method. Parts of the pump may be too much oiled or oiled insufficiently. For adequate operation, the quantity of oil in the trough is essential. If there is insufficient oil, wear can happen between critical parts and too much oil will trigger unnecessary lubrication, which can contribute to hydraulic locking. In a spray tube scheme, the sort of oil used and its viscosity are also essential. The oil must be sufficiently dense to provide adequate lubrication and adherence to the dippers, but not so viscous that it will heat up as churned in the oil trough. Oil purity is also critical ; oil should be frequently filtered and replenished if needed.

2.2 Splash and pressure lubrication system:

Splash and strain lubrication scheme is a splash and strain system mixture. In this scheme, a pump supplies the lubricating oil to the primary and camshaft bearings under stress. The oil is also aimed to lubricate bearings at the large end of the connecting rod, screw pin, gudgeon pin, button rings and cylinder in the shape of a nozzle splash or sprayed by a scoop or dipper.

2.3 Pressurized lubrication system:

The lubricating oil is provided by a pump under stress to all components that require lubrication in the pressurized lubrication scheme. Crank shaft, camshaft and connecting rod bearing surfaces are provided with the oil under stress to the primary bearings. Holes driven through the primary bearings of the crank shaft, transmit oil through the gap inserted in the connecting rod to the large end bearings and tiny end bearings. To verify the flow of oil to different components, a pressure gage is given. A premium spin-on oil filter is included in the strain scheme. For selecting single cylinder and connecting rod bearing surfaces, pressure lubrication is used.

3. Dry-sump lubrication system:

With multiple stages, the dry sump pump is designed to ensure that all the oil is scavenged from the pan. This also leads to the removal of surplus water from the crankcase, and is the reason why they are called "dry sump," meaning that the oil tank is frozen. The supply of oil is transported from the outside tank. The sump oil is passed through a scavenging pump to the internal storage tank through filters. The storage tank water is poured through the engine cylinder and the oil refrigerator. The temperature of the oil may differ between 3 and 8 bar.

Generally used for heavy-duty motors is the dry-sump lubrication scheme.

Be sure to use all filters when dealing with any lubricating system to keep dust out of the lubricant. Change lubricants frequently according to the suggestions of the maker and inspect your facilities daily. Any efficiency modifications should warn you to possible issues.
