The composition comprises, by mass, 70-80 parts of DAH medium-load rotary-type air compressor oil, 10-15 parts of bronze mica, 1-3 parts of aluminum oxide and 1-2 parts of sodium dodecyl sulfate. According to the novel DAH medium-load rotary-type air compressor oil composition, exceedingly corrosion-resistant hard cermet anti-abrasion layers are formed on a cylinder sleeve and a rotor face in an air cylinder of a compressor, gleithretter motion remains smooth, a failure rate is reduced, and service life of the compressor is prolonged by more than twice that of the compressor before.
Description
Technical field
Rotary air compressor oil composition and method of making the same and application the present invention relates to load in a kind of DAH, said composition is suitable for cylinder sleeve and the rotor in lubricated oil cooling rotary compressor cylinder, especially be suitable for the lubricated of lubricated low, middle load helical air compressing engine, belong to material technology field.
Background technology
Rotary compressor is a kind of by the rotatablely moving of one or more rotors in cylinder, and produces working volume and changes, and realizes the displacement type compressor of gas compression.The applying working condition of principle of work, oiling system and the lubricating oil of rotary compressor, has many differences with general reciprocation compressor.Wherein oil-cooled type screw compressor is most popular a kind of form.Lubricating oil, by direct cylinder injection pressure space, carries out cooling, sealing and lubricated, then drains into together with pressurized gas in separator, carries out gas-oil separation, and lubricating oil is reclaimed and recycles.Oil cooling rotary compressor oil is in most evil bad well-oxygenated environment, and it is sprayed into and vaporificly contacts with hot compressed air, is subject to the impact of impurity in air, dust, and the catalysis of the metal such as copper, steel in water cooler.Lubricating oil is oxidized, can cause viscosity to increase, and the incoming call amount of oil reduces, and compressor temperature raises.The paint film and the carbon distribution that form can make vane motion dull, cause compressor operating to lose efficacy.The common exhaust temperature of one stage compressor is higher, makes airborne moisture be steam condition and takes out of outside machine with air-flow.At present conventional rotary compressor, in order to improve pressure efficiency, is all two stages of compression, but in two-stage compressor, and Yin Wendu is too low and the large quantity of moisture that condenses makes emulsification of lubricant sometimes.The result of emulsification can cause oil consumption to increase, and makes cylinder sleeve and rotor wear and corrosion aggravation in compressor housing.
