Description
Technical field
The invention belongs to field of lubricant, relate to a kind of castor-oil plant base wind-power electricity generation dedicated gear oil.
Background technology
Wind energy has been subject to the attention of various countries as a kind of valuable source of current green novel energy source exploitation.National governments lay down preferential policies one after another, encourage the enterprises and individuals to play an active part in the wind-power electricity generation cause, strengthen the exploitation dynamics of wind-powered electricity generation.Wind-power electricity generation is short due to the construction period, the installation scale flexibly, not consume fuel, the advantage such as free from environmental pollution, become important fresh combatants of present new energy field.
Wheel casing is a most important integral part in wind power equipment, is also consumption and a highest product of performance requriements in the use of lubricating oil product simultaneously.According to the experience of European wind-powered electricity generation industry, in the major cause that causes wind energy turbine set to stop transport, the infringement of wheel casing accounts for 35%, and wheel casing becomes a major equipment of the normal operation of wind energy turbine set.Wheel casing can generally at 20-50r/min, by the accelerating function of wheel casing, make the rotating speed of high speed shaft reach 1000-1500r/min very low wind speed round, thereby makes generator with the rotating speed rotation near rated output, reaches the purpose of generating.In wind turbine gearbox, lubricant is oilgear and bearing simultaneously, and the lubricant product that therefore is applied to wind turbine gearbox must satisfy the lubrication needs of gear and bearing simultaneously.Because wind turbine equipment involves great expense, work under bad environment, equipment is higher, on-the-spot inconvenience is carried out detachable maintaining to major parts, and require the work characteristics such as long service life in design, wind-power electricity generation gear oil used is except having fabulous extreme pressure and antiwear behavior, cooling performance and cleaning performance, also should have good thermal oxidation stability, demulsification performance, viscosity temperature characteristic, low-temperature performance and long work-ing life, also should have simultaneously lower frictional coefficient to reduce the power loss in geartransmission.
The wind-power electricity generation gear oil accounts for oil mass 3/4 left and right that wind-power electricity generation is always used oil mass.Domestic demand to the wind-power electricity generation gear oil should be the 250t left and right at present, and to the year two thousand twenty, domestic wind turbine kludge capacity will reach 3 * 10
7KW, the annual requirement of wind-power electricity generation gear oil will reach the 6000t left and right.Due to the fast development of wind generating technology both at home and abroad, its relevant lubricated product, especially wind-power electricity generation gear oil will have a more wide market application foreground.At present, mainly contain mineral oil origin and synthetic hydrocarbon type (PAO type) as the wind-power electricity generation gear oil.Although mineral oil origin is cheap, its use properties is not enough, and the life-span is short; Though and synthetic hydrocarbon type wind-power electricity generation gear oil has long work-ing life, it has the shortcoming that causes sealing material to shrink.In addition, mineral oil and synthetic hydrocarbon wind-power electricity generation gear oil biological degradability are poor, can cause environmental pollution after leaking into environment.Therefore, wind-power electricity generation gear oil use properties is not enough, the life-span is short and the environmental pollution person's urgent problem that is the working lubricant.
Viscotrol C mainly is comprised of ricinolic acid glyceryl ester, is unique a kind of Vegetable oil lipoprotein that integrates three kinds of functional groups of hydroxyl, ester group, two key, and the singularity of this structure has been given it and had diversity of chemical modification and synthetic processing.Has good biodegradability by the castor oil modified castor-oil plant base base oil that obtains, low-temperature performance is good, viscosity index is high, thermal oxidation stability is excellent, extreme pressure and antiwear behavior is good, can be used for preparing all wind power equipment lubricants (wind-power electricity generation gear oil, hydraulic efficiency oil and lubricating grease) of excellence of properties.Because castor-oil plant base system row wind power equipment lubricant has biodegradable characteristics, can realize the whole green lubrication of wind-powered electricity generation industry.The performance that castor-oil plant base wind-power electricity generation gear oil can solve present wind-power electricity generation gear oil existence is not enough, the problems such as the life-span is short, environmental pollution, satisfies the lubricating requirement of wind power generating set.

Due to the special molecular structure of castor-oil plant base base oil and the susceptibility good to antioxidant addn, it is qualitative that castor-oil plant base wind-power electricity generation dedicated gear oil has excellent oxidation, has longer work-ing life.Specific to the application of wind-powered electricity generation, under normal service condition, castor-oil plant base wind-power electricity generation dedicated gear oil can use more than 3 years, can greatly reduce the number of times of changing oil.The prolongation in work-ing life can reduce the workload of unit maintenance, shortens stop time, improves generating efficiency.Adopt the rotary oxygen bomb method to measure the oxidation stability of wind-power electricity generation gear oil, the oxidation induction time of certain international well-known wind-power electricity generation gear oil is 260min, and the oxidation induction time of castor-oil plant base wind-power electricity generation dedicated gear oil surpasses 800min, is more than 3 times of well-known wind-power electricity generation gear oil oxidation stability.Supposing that every unit is changed oil at every turn all needs 8 hours, and for a wind energy turbine set that 33 1.5MW wind-powered electricity generation units are installed, the total down-time of at every turn changing oil just reaches 264 hours so.If the rate for incorporation into the power network according to 0.5 yuan of every kilowatt-hour is calculated, the power generation loss of the whole wind energy turbine set of once changing oil just reaches 200,000 yuan.This just means and uses castor-oil plant base wind-power electricity generation gear oil in its work-ing life, only just can bring the interests of 400,000 yuan to the user because of minimizing change oil shutdown aspect.
3) biodegradable, environmental protection
The process that the biological degradation of lubricating oil refers to that lubricating oil is oxidized under microbial process, decomposes, final product is carbonic acid gas and water, [referring to: 1. Yang Chinese etc., vegetables oil prepares the hope of green lubricants, Chinese oil, 2003,28 (11); 2. leaf is civil and military etc., the characteristics of green lubrication agent, sufacing, 2002,31 (3); 3. Zheng just sends out and waits, the research overview of environmental friendly lubricant, sufacing, 2004,33 (2)], the lubricating oil palliating degradation degree can reach and just be decided to be biological degradability lubricating oil more than 67%.Castor-oil plant base wind-power electricity generation gear oil has excellent biological degradability, can effectively prevent the pollution of the environment.
