Abstract
The present invention belongs to the field of petrochemical technology. The present invention is mainly using special densifier to densify medium-viscosity refined oil, adding additives for resisting oxidation, resisting water, antirust, antifriction, extreme pressure lubricating and othre purposes separately and adding solid bead so as to compose semi-fluid gear oil composite for reduction box of oil pumping unit. The lubricating oil for gear box has good extreme pressure lubricating performance, good temperature stability and other advantages.
Description
(1) technical field
The present invention relates to antitheft gear oil composition of a kind of oil-field oil pumper reduction box and preparation method thereof, belong to petrochemical industry.
(2) background technology
The oil-field oil pumper reduction box is a kind of general transmission apparatus.At present, the oil field generally adopts machinery oil or gear oil to do lubricant to lubricate, and in the use, the ubiquity following point: 1. oil consumption is big, wastes energy at the scene.Because of good fluidity, stolen by the lawless person easily.Drain period short, increased the working strength of maintaining, as on request, the oil-field oil pumper reduction box must change twice oil every year, spring, once winter was once.3. machinery oil can not meet the demands fully, and mechanical wear is very fast, and some oil field is stolen in order to prevent lubricating oil, welds dead wheel casing, and lubricating oil can not in time be changed, and because of mechanical oil deterioration, has quickened the wearing and tearing of wheel casing gear, makes shortened equipment life.4. comprehensive cost height.
(3) summary of the invention
The present invention is directed to the shortcoming of prior art, a kind of novel oil-field oil pumper speed reduction gear box oil is provided, make it to have and caution against stealing, anti-leak, extreme boundary lubrication is good, characteristics such as heatproof good stability and life cycle are long, stolen easily, the lubricity difference that solves that plain oil exists and work-ing life short problem.
To the effect that of the present invention: with extraordinary viscosifying agent multiviscosisty high viscosity treated oil, and adding antioxygen, waterproof, antirust, anti-friction and extreme pressure profit additives such as sliding, and solid microballon lubricant, the antitheft gear oil composition of oil-field oil pumper reduction box that synthesizes the semi-fluid shape, its component is as follows, is weight part: the refining base oil B 5-35 part extreme boundary lubrication membrane-forming agent 1-8 part water-resisting agent 3-10 part of the refining base oil A 50-90 part medium viscosity of extraordinary viscosifying agent 5-30 part oxidation inhibitor 0.4-10 part solid microballon lubricant 0.2-12 part rust inhibitor 0.6-9 part medium viscosity
Described extraordinary viscosifying agent is ten dihydroxystearic acids or hydrogenated castor oil.
Described oxidation inhibitor is sulphur phosphorus fourth octyl group zinc salt or 2,6 ditertiary butyl p cresol.
Described solid microballon lubricant is high temperature resistance wear resistant resin microballon or molybdenumdisulphide.
Described rust inhibitor is phenylpropyl alcohol triazole or dinonyl bitter edible plant barium sulfonate.
Described extreme boundary lubrication membrane-forming agent is a dialkyl dithio ammonium cesium formate.
Described water-resisting agent is 124 Triazole fatty acid amine sodium salt or 124 Triazole fatty acid amine sylvite.
The refining base oil A of described medium viscosity is refinery medium viscosity base oil or CA-40 bavin machine oil.
The refining base oil B of described medium viscosity is refining 4 line oil of refinery or QA-40 steam turbine oil.
Gear oil composition for reduction box of oil pumping unit preparation method of the present invention is as follows:
1. refining base oil A 50-90 part of medium viscosity and viscosifying agent are added in the reactor, under 80-120 ℃ of temperature, carry out the multiviscosisty reaction, reaction times 4-6 hour;
2. after the multiviscosisty reaction finishes, be warmed up to 140-220 ℃, add other additives such as oxidation inhibitor, rust inhibitor, extreme boundary lubrication membrane-forming agent, water-resisting agent then, and add base oil B 5-30 part, carry out secondary reaction;
3. after secondary reaction finishes, cool to 120-170 ℃, add solid microballon lubricant then;
4. cleavage reaction 1-2 hour, by adding base oil B1-5 part cone governor in-degree 400-600 (10
-1Mm)/25 ℃, go out the still packing when cooling to 70-900 ℃ then.
Main innovate point of the present invention is:
1. used solid microballon lubricant, improved lubricity, high voltage performance is good, and the drain period that makes lubricating oil is by being increased to 1-2 half a year.
2. lubricating oil has special performances, and lubricating oil can only be used in the oil pumper wheel casing, can burn charing in case be used for some component of diesel engine or tractor-luboil, thereby machine is burnt, and prevents that thoroughly lubricating oil is stolen.
3. in lubricating oil, added extraordinary viscosifying agent, made whole system become a kind of unlikely automatic mobile stiff ointment state.When mechanical position remained static, lubricating oil had the ability that keeps self shape, prevented to leak and the boring stealing; When gear was kept in motion, shear-stress increased, and lubricating oil can flow deformation can take place as viscous fluid, by the extreme boundary lubrication that the adsorbed lubricating film that forms on moving parts has improved lubricating oil, can prevent the spatter loss of lubricating oil simultaneously.Therefore, the lubricant of the present invention's research has good lubrication and seal and theftproof performance.
4. in lubricating oil, add water-resisting agent, improved the water resisting property of lubricating oil, guaranteed the lubricated reliability of mechanical part.
