Besides lubrication, what is another purpose of lubricating oil on a turbine?

The role of lubricating oil extends beyond mere lubrication; it also serves to carry heat away from the bearings. In a turbine, the bearings experience significant friction and generate heat during operation. The lubricating oil circulates through these components, absorbing excess heat and preventing overheating. This heat dissipation is crucial for maintaining the integrity and performance of the bearings, ensuring they operate smoothly and efficiently over time. By managing the temperature within the turbine system, the lubricating oil helps to enhance equipment longevity and reliability. This heat management aspect is vital in high-speed and high-load applications found in turbines, where operational stability is essential.
