Abstract

The invention relates to the technical field of lubricating oil, in particular to fully-synthesized wind power main gearbox lubricating oil which is prepared from the following raw materials in parts by weight: 80-95 parts of poly-alpha olefin base oil, 5-15 parts of synthetic ester base oil, 0.3-3 parts of an extreme pressure anti-wear agent, 0.3-3 parts of an antioxidant, 0.1-3 parts of an anti-rust agent, 0.1-3 parts of a demulsifying agent and 0.005-0.3 part of an anti-foaming agent. The invention further provides production equipment for synthesizing the wind power main gear box lubricating oil. The production equipment comprises a barrel body and a filtering module, the invention also provides a preparation method of the synthetic wind power main gear box lubricating oil, which comprises the following steps: S1, adding the base oil, and heating; s2, adding an antioxidant, heating and stirring; and S3, adding the rest raw materials, cooling and filtering. According to the invention, the extreme pressure anti-wear agent, the antioxidant and the antirust agent are added into the base oil, so that the performance of the lubricating oil is better.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a fully synthetic wind power main gearbox lubricating oil, a production device and a preparation method. Background technique [0002] With the continuous development of my country's wind power industry, the demand for oil for wind turbines has also increased year by year, and wind power has become the third largest power source after thermal power and hydropower. The main gearbox is the core component of the wind turbine. Its basic function is to convert the low-speed and high-torque power generated by the wind to drive the blades into the high-speed and low-torque power required by the generator. Therefore, the reliability of the gearbox often directly affects wind power. The power generation efficiency and service life of the unit. [0003] Most of the wind farms are built in the desert Gobi, sea, mountains and other remote areas in the wild, which are easily affected...
