What is the function of the oil seals?

The function of oil seals is primarily to prevent oil from leaking past the shafts and sumps. These seals create a barrier that keeps the oil contained within the system, ensuring that it effectively lubricates moving parts. This containment is crucial for maintaining the proper functioning of the gas turbine system, as any loss of oil could lead to increased friction, wear, and potential failure of the components that rely on adequate lubrication.

This sealing function not only helps preserve oil levels but also reduces the risk of contamination, which can occur if oil mixes with contaminants outside the system. Furthermore, maintaining proper oil levels enhances the overall efficiency and reliability of the gas turbine, as the lubrication system is vital for its operation. Hence, the role of oil seals is critical in ensuring the integrity of the lubrication system by preventing leaks.
