Abstract

The invention discloses steam turbine oil which comprises the components by weight percent: 0.1-2% of amine antioxidant, 0.1-0.9% of anti-wear reagent at extreme pressure, 0.02-0.5% of ashless rust inhibitor, 0.01-0.05% of metal deactivator, 0.001-0.01% of anti-foaming agent and the balance of base oil; the base oil is III type base oil, wherein the content of saturated hydrocarbon is more than 90%, and the content of sulphur is less than 0.03%; the amine antioxidant is selected from alkylated diphenylamine, phenyl naphthylamine or a mixture of the alkylated diphenylamine and the phenyl naphthylamine; the anti-wear reagent at extreme pressure is one or a mixture of more than one of alkyl phosphorothioate, alkyl phosphate, alkyl phosphate amine salt and alkyl sulfo-carbamic acid ester, wherein alkyl group is C2-C20 hydrocarbyl; and the ashless rust inhibitor is vinyl succinic acid, or phosphate amine salt, or a compound mixture of the vinyl succinic acid and the phosphate amine salt. The steam turbine oil has the advantages of being excellent in quality, long in service life, free from pollution and the like, is suitable for lubricating bearings and circulation adjusting systems of large-sized, medium-sized and small-sized steam turbines (water turbines), and is mainly used for a steam turbine or gas turbine with the power more than 300MW.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil and relates to a steam turbine oil. Background technique [0002] With the development of the steam turbine manufacturing industry, steam turbine units are developing towards high temperature, high pressure, high speed and large capacity, and the requirements for the oxidation resistance, extreme pressure resistance and lubricating performance of steam turbine oil are gradually increasing. At present, domestic oil products are generally only used for steam turbines below 300MW. Domestic commercially available steam turbine oil products generally have insufficient extreme pressure lubrication performance, insufficient rust and corrosion resistance, and irritating odors during processing, which may lead to greatly shortened tool life, corrosion of workpieces during processing, and The reduction of surface quality and the deterioration of the processing environment greatly reduce the product...
