What is the role of lubricating oil in a compressor?

The role of lubricating oil in a compressor is multifaceted, but primarily it serves to prevent corrosion of the compressor parts. Moisture and contaminants can lead to corrosion, which would ultimately compromise the integrity and efficiency of the compressor components. By providing a protective layer, the lubricating oil minimizes direct contact between metal surfaces and any corrosive agents, thus preserving the lifespan and reliability of the equipment.

In addition to corrosion prevention, lubricating oil also helps in other ways, such as providing cooling for the compressor during operation by absorbing some of the heat generated, and enabling smoother operation by reducing friction between moving parts. This reduction in friction can also lead to improved efficiency, as less energy is wasted in overcoming resistance. However, the primary focus here is on how lubricating oil protects components from corrosion, ensuring the effective and prolonged operation of the compressor.
