Why Lube Oil is Used In Turbines?

Lube oil is essential in turbines for several key functions:

1. Lubrication:

   - Reduces Friction:Lube oil forms a thin film between moving metal surfaces, such as bearings and shafts, reducing friction and preventing metal-to-metal contact.

   - Minimizes Wear:By reducing friction, lube oil minimizes wear and tear on components, extending the life of the turbine.

2. Cooling:

   - Heat Absorption:As the turbine operates, its components generate heat due to friction and other processes. Lube oil helps absorb this heat.

   - Heat Dissipation:The oil carries the absorbed heat away from critical components to an oil cooler, where it is dissipated.

3. Cleaning:

   - Contaminant Removal: Lube oil helps clean the turbine's internal components by carrying away contaminants, such as metal particles, dirt, and combustion by-products.

   - Filtration: The lube oil system typically includes filters that trap these contaminants, keeping the oil clean and the system functioning efficiently.

4. Sealing:

   - Prevents Leaks: In some turbine designs, lube oil acts as a seal to prevent the leakage of gases or steam between high-pressure and low-pressure zones within the turbine.

   - Protects Against Corrosion: The thin oil film provides a protective layer that helps prevent corrosion on metal surfaces.

5. Hydraulic Control:

   - Operation of Actuators and Valves: In some turbine systems, lube oil is used to operate hydraulic actuators and control valves that regulate the turbine's speed and other functions.

Overall, lube oil is critical for the smooth, efficient, and reliable operation of turbines, ensuring components stay cool, clean, lubricated, and protected from damage.
