As one of the important components of a generator set, the long-term high-speed rotation of a steam turbine can lead to physical phenomena such as high friction and significant wear. The lubricating oil of the steam turbine, as an essential component of the turbine's supporting parts, plays a crucial role in the use and maintenance of the turbine.

Turbine lubricating oil is made by blending base oil and additives. It has high temperature, high pressure, high speed lubrication performance, as well as good oxidation resistance, corrosion resistance, foam resistance and other properties. In harsh environments such as high temperature, high pressure, and high speed, providing comprehensive lubrication support for steam turbines, reducing wear between metal parts, protecting the integrity of working components, and providing necessary guarantees for the normal operation of steam turbines.

The characteristics and requirements of turbine lubricating oil are also relatively high. For example, turbine oil needs to have excellent fluidity to ensure that the lubricating oil can quickly reach the area where friction and wear are most concentrated during high-speed lubrication; Turbine oil also needs to have a higher viscosity index and oxidation stability to adapt to the high temperature and high pressure environment during turbine operation; Lower low-temperature performance to ensure that the turbine oil does not become too viscous and affect the start-up before the unit starts.

The selection and application of turbine lubricating oil directly affect the long-term operational performance of the turbine. Therefore, when choosing, suitable turbine lubricating oil should be selected based on the actual application and requirements of the lubricating oil in the turbine to ensure the safe, stable, and efficient operation of the turbine. At the same time, it is also very important to regularly replace and monitor the turbine lubricating oil.
