What are the two types of compressor lubrication systems?

The two types of compressor lubrication systems are indeed forced and splash lubrication. Forced lubrication involves the use of a pump to circulate oil throughout the compressor, ensuring that all necessary components receive a sufficient amount of lubricant at all times. This method is particularly effective in maintaining consistent lubrication and preventing wear by ensuring that the oil reaches the bearings and other moving parts under pressure.

In contrast, splash lubrication works through an entirely different mechanism, relying on the motion of the compressor's parts to splash oil around. As components move, they create splashes or droplets of oil that coat the surfaces requiring lubrication. While this method can be simpler and more cost-effective, it may not deliver oil to the components as reliably as a forced system, especially in larger compressors where there is a greater distance between oil sources and moving parts.

Understanding these two systems is essential for maintaining compressor efficiency and longevity, as the choice of lubrication method impacts the operational reliability and maintenance needs of the refrigeration system.
