Abstract
The invention discloses a lubricating-oil composition of a speed reducing machine in a gas turbine for ship. The lubricating-oil composition comprises the following components in percent by mass: 2-4% of antioxidant, 5-6% of antiwear agent, 0.1-0.4% of antirusting agent, 0.06-0.08% of metal passivating agent, 0.05-0.3% of demulsifying agent, 0.005-0.01% of anti-foaming agent, 1-2% of oiliness agent and the balance of base oil. The lubricating-oil composition has the obvious advantages that the comprehensive performance is good, and all performance indexes meet the use requirements; not only are the antioxygen, anticorrosion and antiwear performances good, but also the antirusting, anti-salt-fog and antifoaming performances are quite excellent; the lubricating-oil composition also meet the use requirements of the gas turbine for ship in the aspects of acid control capability, clean dispersity and rubber adaptability; and the base oil is compounded and synthesized by selecting diester and polyol ester which have excellent performance, so that the base oil assuredly has good heat stability, good viscosity-temperature characteristic, excellent low-temperature mobility, low volatility and good lubricity simultaneously.
Description
Technical field
The present invention relates to a kind of boats and ships step-down gear lubricating oil composition in the internal combustion turbine.
Background technology
Development along with China's gas turbine technology, the technology of the UGT25000 type internal combustion turbine of particularly introducing from Ukraine, and the LM2500+G4 series technique of introducing in the recent period GE be used for after the construction in power house, use internal combustion turbine to become the inexorable trend of ship power development on the boats and ships, production domesticization auxiliary facility cry is surging; But China with the development of step-down gear lubricating oil or a weakness in the internal combustion turbine, does not also have to formulate the lubricating oil standard that is used for the boats and ships large-scale gas turbine to boats and ships up till now.Therefore significant with the development of internal combustion turbine step-down gear lubricating oil to boats and ships.
The lubricating oil system of China's boats and ships internal combustion turbine mainly is two portions independent design before and after being divided at present, this be because gasifier anterior what use is rolling bearing, rear work turbine and reducer gear transmission are to use sliding surface bearing, and these two parts have larger difference to the requirement of lubricating oil.Therefore, be necessary to develop a kind of lubricating oil that is applicable to step-down gear in the boats and ships internal combustion turbine, this is all significant to economy and social development.
Summary of the invention
The technical problem to be solved in the present invention provides a kind ofly not only has good oxidation resistance energy, corrosion resistance, wear resistance, rustless property, salt fog resistance performance, emulsion resistance and antifoam property, and has good sour controllability, rubber adaptability and the boats and ships of long oil draining period with step-down gear lubricating oil composition in the internal combustion turbine.
The present invention solves the problems of the technologies described above with following technical scheme:
A kind of boats and ships step-down gear lubricating oil composition in the internal combustion turbine, said composition component and content are by mass percentage: oxidation inhibitor 2～4%, anti-wear agent 5～6%, rust-preventive agent 0.1～0.4%, metal passivator 0.06～0.08%, emulsion splitter 0.05～0.3%, kilfoam 0.005～0.01%, oiliness improver 1～2%, surplus are base oil.
The base oil of described lubricating oil composition is the compound of poly-alpha olefins (PAO) and pentaerythritol ester, accounts for respectively mass percent 40-45%, 55-60%.
The oxidation inhibitor of described lubricating oil composition is with accounting for the phenyl-a-naphthylamine of mass percent 40-50% and the 3.5-di-t-butyl-4 hydroxyl oxidize styracin alkyl (C of 50-60%
7, C
9Branching) ester or butyl octyl pentanoic or sulphur naphthazin(e) are composite.
The anti-wear agent of described lubricating oil composition is to be that 40～60% di-n-butyl phosphites and 40～60% amino sulfuration esters are composite with mass percent.
The metal passivator of described lubricating oil composition is that mass percent is that 30～70% thiadiazoles derivatives and 30～70% alkyl diphenylamines are composite.
The rust-preventive agent of described lubricating oil composition is to be the petroleum sodium sulfonate of 60～70% benzotriazole and 15～20%, the recombiner of 15～20% dodecenylsuccinic acid ester by mass percentage.
The emulsion splitter of described lubricating oil composition is the recombiner of the condenses of the multipolymer of propylene oxide/oxyethane and amine and oxyethane, and recombiner is composite by 1: 1 mass ratio.
The kilfoam of described lubricating oil composition is the homopolymer of methacrylic ester.
The oiliness improver of described lubricating oil composition is to account for mass percent 45～55% oleic acid ethylene glycol fat and 45～55% 124 Triazole aliphatic amide fat are composite.
Boats and ships of the present invention have with the remarkable advantage of step-down gear lubricating oil in the internal combustion turbine:
1. the good combination property of lubricating oil composition of the present invention, property indices all reaches service requirements.Be in particular in not only have good antioxygen, anticorrosive, wear resistance, and antirust, salt fog resistance, emulsion resistance and antifoam property are also quite outstanding, in the service requirements that also meets the boats and ships internal combustion turbine aspect sour controllability, detergent-dispersant performance, the rubber adaptability, it is lubricated to be applicable in the boats and ships internal combustion turbine step-down gear.
2. base oil has been selected dibasic acid esters and the polyol ester composite synthesis base oil of excellent performance, guarantees that base oil has good thermostability, good viscosity-temperature characteristics, superior low-temperature fluidity, low volatility and good oilness simultaneously.
Embodiment
Step-down gear lubricating oil composition specific embodiment is as follows in the boats and ships internal combustion turbine:
Embodiment 1:
