What are the three basic types of lubrication systems?

The correct identification of the three basic types of lubrication systems as gravity, splashed, and forced is rooted in the fundamental design and operation principles of mechanical systems, particularly within gas turbine engines and other machinery.

Gravity lubrication systems utilize the force of gravity to allow oil to flow from the reservoir to the lubricant points. This system is simple and effective for low-speed applications where the lubricating oil moves by gravity and can adequately supply lubrication to surfaces without the need for mechanical assistance.

Splash lubrication systems operate on the principle of using rotational motion to splash oil onto the parts that require lubrication. This method is commonly used in engines where rotating components dip into the oil supply, ensuring that there is adequate lubrication on all necessary surfaces as the components rotate.

Forced lubrication systems involve the use of a pump to circulate oil throughout the system. This method provides a consistent and controlled flow of lubricant to all critical areas, ensuring that even high-speed or high-temperature operating conditions are adequately addressed. It is essential for high-performance applications where maintaining optimal lubrication is critical for longevity and efficiency.

These distinctions highlight the versatility and application of each lubrication method, showing how they adapt to different mechanical needs and operational conditions.
