The invention discloses extreme-pressure steam turbine oil. The steam turbine oil is mainly composed of base oil and additives, wherein the base oil is mainly composed of mineral oil, alcohol ester and poly(alkylene) glycol, and the additives of alkylated diphenylamine and / or phosphite ester, macromolecular hindered phenol, sulphur phosphoester, sulphur phosphate, benzotriazole amine salt, benzotriazole derivative, dodecenylsuccinic acid (ester), the tetrapolyoxy trimethylene derivative of amine, and siloxane composite are added. The extreme-pressure steam turbine oil is great in comprehensive performances including foaming resistance, water dispersibility, air release performance, detergency and filterability, especially excellent in extreme-pressure wear resistance, thermo-oxidative stability and oil sludge control and dispersion capacity, and capable of greatly meeting the lubricating needs of modern gas turbines and large combined cycle steam turbine units with extreme-pressure requirements.
Description
technical field [0001] The invention relates to a lubricating oil composition, which is especially suitable for lubricating industrial gas turbines, large gas-steam combined cycle turbines, speed-adjusting transmission gearboxes and steam turbine compressor units with extreme pressure requirements. Background technique [0002] With the rapid development of my country's electric power industry, high-parameter large-scale units have become the backbone of power grids in various regions. Gas turbines with advantages such as high efficiency, light weight, compact structure, and flexible mobility, and gas-steam combined cycle generator sets that have further improved thermal efficiency have become It accounts for the main part of the new installed capacity of power generation equipment. The installed power of the gas turbine is large, the oil tank design is small, the oil circulation speed is fast, the oil temperature is high during operation, and the temperature at the bearing i...
