Abstract
A lubricant composition for a fuel gas generator of a ship gas turbine is characterized in that the lubricant composition comprises the following compositions in percentage by weight: 1%-4% of antioxidant, 0.06%-0.08% of metal deactivator, 0.05%-0.3% of rust inhibitor, 3.5%-4.5% of detergent, 7%-10% of dispersing agent, 0.05%-0.3% of de-emulsifier, 0.005%-0.01% of anti-foaming agent and the residual amount base oil. Aiming at the requirements of the fuel gas generator of the ship gas turbine, poly-Alfa-olefin (PAO) and pentaerythritol ester are compounded to be used as the base oil for the lubricant of a rolling bearing, and antioxidant, detergent and dispersing agent, and anti-foaming agent are preferably selected by the fuzzy analytical hierarchy process to be used for preparing the lubricant composition. The lubricant composition product has good stability, oxidation resistance, corrosion resistant, anti-foaming property and the like. All indexes reach the application requirement, and the lubricating requirements of the fuel gas generator of the ship gas turbine can be met.
Description
Technical field
The present invention relates to a kind of internal combustion turbine gasifier lubricating oil, especially boats and ships internal combustion turbine gasifier rolling bearing lubrication oil compositions.
Background technology
Internal combustion turbine is the heat engine of the new class type after steam turbine and oil engine.Its feature be have that quality is light, volume is little, single-machine capacity is large, startup is fast, pollute less, vibration is little, thermo-efficiency is high and combustion gas initial temperature height, is convenient to realize the cascade utilization of energy, good economy performance.The boats and ships internal combustion turbine is a kind of internal combustion of continuous rotary, the Novel heat engine of turbomachine formula.It is different from piston type internal combustion engine and external combustion type steam turbine, is a kind of with the isobaric internal combustion of continuous flow gaseous media, and the heat engine of the turbomachine formula of continuous rotary.
What the boats and ships internal combustion turbine was walked is by the improved road of aero engine technology, therefore just should carry out boats and ships with improving.This is because aircraft engine is the environment that uses by aviation with relevant design specifications development and design.Its parameter, operating mode, material, structure and operating performance also not exclusively are fit to the requirement that boats and ships use in rivers, ocean.Therefore must be according to the boats and ships working conditions, the boats and ships internal combustion turbine is proposed a series of concrete technical requirementss (humidity, vibration, salt fog are long-time, the external conditionss such as continuous wave high power output), aircraft engine is carried out the improvement and design manufacturing.
The boats and ships internal combustion turbine also has various subsystems and the auxiliary facility of many assurance internal combustion turbine normal operations except the major partss such as pneumatic plant, fuel chamber and turbine.Comprise air intake filter before lubricating oil and lubricating oil tightness system, start-up system, prime the fuel system, air cooling, turning gear and the compressor air inlet machine etc.The lubricating oil system of boats and ships internal combustion turbine is comprised of lubrication box, lubricationpump (oil feed pump and dump pump), lubricating oil interchanger, lubricating oil filter, pressure reduction or door, oil-gas separator, centrifugal ventilator, magnetic chip detector, Lubricating oil nozzle and conduit.The oiling system of boats and ships internal combustion turbine is usually designed to two independently systems, and the lubricating oil system of gasifier part is also referred to as front oiling system; And the parts of lubricating oil system of the transmission mechanism of work turbine and power set is called rear lubricating oil system.
The boats and ships internal combustion turbine has proposed strict demand because working condition is harsh to lubricating.Gasifier adopts rolling bearing, because the sea contact with air is directly arranged, need anticorrosive, salt fog resistance, high temperature resistance etc., therefore require the gasifier lubricating oil viscosity not only will keep enough values, in order to keep appropriate oil film thickness, thermal oxidation stability is had relatively high expectations, and good air release, preferably sticking warm nature and higher flash-point will be arranged itself, to adapt to preferably high-intensity recycling, require also that antirust and antiseptic property is outstanding, demulsification performance is good.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of boats and ships internal combustion turbine gasifier rolling bearing lubrication oil compositions that stability, oxidation-resistance, erosion resistance are excellent, over-all properties is higher, can satisfy boats and ships internal combustion turbine operating mode that has.
The present invention solves the problems of the technologies described above with following technical scheme:
A kind of boats and ships internal combustion turbine gasifier lubricating oil composition, said composition component and content are by mass percentage: oxidation inhibitor 1%-4%, metal passivator 0.06%-0.08%, rust-preventive agent 0.05%-0.3%, purification agent 3.5%-4.5%, dispersion agent 7%-10%, emulsion splitter 0.05～0.3%, kilfoam 0.005%-0.01%, surplus is base oil.
The base oil of described lubricating oil composition is the compound of poly-alpha olefins (PAO) and pentaerythritol ester, and both account for respectively mass percent 40-45% and 55-60%.
The oxidation inhibitor of described lubricating oil composition is to be with the phenyl-a-naphthylamine of 40-50% and the 3.5-di-t-butyl-4 hydroxyl oxidize styracin alkyl (C of 50-60% by mass percentage
7, C
9Branching) ester or butyl octyl pentanoic or sulphur naphthazin(e) are composite.
The metal passivator of described lubricating oil composition is to be that 30～70% thiadiazoles derivatives and 30～70% alkyl diphenylamines are composite by mass percentage.
The rust-preventive agent of described lubricating oil composition is to be that petroleum sodium sulfonate, 15～20% the dodecenylsuccinic acid ester of 60～70% benzotriazole and 15～20% is composite by mass percentage.
The purification agent of described lubricating oil composition is by mass percentage for composite with 60～70% synthetic sulfonic acid magnesiums and 30～40% low alkali value calcium mahogany sulfonates.
The dispersion agent of described lubricating oil composition is to be that 60～50% high molecular weight polyisobutylene succimides and 40～50% boronation polyisobutene butanediamine (nitrogenous) are composite 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 present invention is directed to the requirement of boats and ships internal combustion turbine gasifier, lubricating oil to rolling bearing adopts poly-alpha olefins (PAO) and pentaerythritol ester compound as base oil, by using Fuzzy AHP the oxidation inhibitor in the lubricating oil, detergent-dispersant additive, foam reducing composition is preferably prepared.Product has satisfactory stability, oxidation-resistance, erosion resistance, anti-bubble etc.Its indices all reaches service requirements, can satisfy boats and ships internal combustion turbine gasifier lubricating requirement.
