Embodiment 1

[0013] A special lubricating oil for wind power generators, its components and weight percentages are as follows:

[0014]

[0015] The invention is a kind of lubricating oil specially used for wind power generators. Its preparation method is as follows: take 60 grams of cracked heavy oil extracted oil, 8 grams of castor oil, 10 grams of phosphoric acid ester, and 8 grams of methyl silicone oil and heat them to 100 ° C, and then add them to react Stir evenly in the still, then, add 5 gram tricresyl phosphates, 1 gram carboxylate amine, 2 gram ethylene oxide-propane block polyethers, 4 gram alkylnaphthalene, 2 gram polymethacrylates, Stirring was continued for 6 minutes to complete. The finished product of the present invention is golden yellow transparent liquid.

Abstract

The invention discloses special lubricating oil for a wind driven generator, belonging to the technical field of lubricating oil. The formula is characterized by comprising extract oil for cracking heavy oil, tricresyl phosphate, pyrazinecarboxamide, ethylene oxide-propane block polyether, vegetable oil, phosphate, alkyl naphthalene, methylsilicone oil and polymethacrylate. The product disclosed by the invention is superior to mineral lubricating oil of the prior art in friction coefficient, service life, thermal-oxidative stability, demulsibility, cold resistance and extreme pressure antiwear property. In addition, the product disclosed by the invention is low in production cost and low in price, and is superior to synthetic lubricating oil in the prior art. Therefore, the product disclosed by the invention belongs to the lubricating oil with high cost performance. The product disclosed by the invention can be applied to the wind driven generator in an extreme environment, and the wind driven generator normally runs.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and the invention relates to a special lubricating oil for wind power generators, in particular to a special lubricating oil for wind power generator gearboxes. Background technique [0002] The working environment of the wind turbine is very harsh, and it has been in the environment of heavy humidity, dust and extreme high and low temperature for a long time. The maintenance of wind power equipment is very difficult, so ensuring reliable and stable long-term operation is the most fundamental requirement. Among them, the gearbox is the main lubrication part of the wind turbine, and the oil consumption accounts for about 3 / 4 of the oil consumption of the wind turbine. The gearbox can change the very low speed of the wind rotor into a very high speed of the generator, and it mostly uses oil pool splash lubrication or pressure forced circulation lubrication. Lubricating oil is greatly affe...
