Abstract

A kind of preparation method of synthetic steam turbine oil provided by the present invention, ester A is mixed by 50-54 parts of diethylene glycol and 50-54 parts of adipic acid, or 25-27 parts of glycerol and 16.7-18 parts of adipic acid Mixing parts; Ester B is mixed with 56-58 parts of diethylene glycol and 28-29 parts of lauric acid, or 56-58 parts of glycerol and 18.7-19.3 parts of lauric acid; Ester C is made of 50-55 parts of diethylene glycol 50-55 parts of phthalic acid, or 25-27.5 parts of glycerin and 16.7-18.3 parts of phthalic acid; then mix ester A with ester B; ester A with ester C; ester B with Mix ester C to obtain base oil; take 52-86 parts of base oil, add 14-48 parts of compound ingredients, and prepare finished oil.

Description

technical field [0001] The invention relates to a lubricating oil for a steam turbine, especially suitable for the lubricating oil of a steam turbine system. The product has good anti-corrosion and anti-rust properties, anti-wear and anti-wear properties, anti-emulsification, anti-oxidation stability and long service life. Background technique [0002] There are many types of steam turbines, and steam turbine oil is the lubricant for all types of steam turbines. In recent years, with the development of the national economy, especially the development of the electric power industry, the demand for steam turbine oil has increased year by year, the quality requirements for steam turbine oil are higher, and the varieties of steam turbine oil are also constantly increasing. [0003] Retrieval literature disclosure: [1] Patent CN02141795 discloses a long-life steam turbine oil lubricating oil composition, which includes: a base oil characterized by a sulfur content of more than 0....
