Problems solved by technology

At present, the commonly used rotary compressors are two-stage compression in order to improve the pressure efficiency, but in the two-stage compressors, sometimes a large amount of water will condense due to the low temperature, emulsifying the lubricating oil
As a result of emulsification, the oil consumption will increase, and the cylinder liner and rotor in the compressor cylinder will be aggravated and corroded

Embodiment 1

[0023] ① Grind phlogopite to particle size ≤ 1 μm, and dry at 280°C for 2 hours;

[0024] ②In parts by mass, weigh 10g of phlogopite obtained in step ①, 70g of DAH medium-load rotary air compressor oil, 1g of alumina, and 1g of sodium dodecylsulfonate and mix them into the closed device to make the vacuum degree reach- 0.08MPa;

[0025] ③Raise the temperature to 85°C, stir at 10000rmp for 30min, adjust the rotation speed to 18000rmp for 10min, and adjust the rotation speed to 28000rmp for 10min;

[0026] ④ Finely disperse in a 1KW ultrasonic generator for 30 minutes.

[0027] The prepared new lubricant (DAH medium-duty rotary air compressor oil composition) was subjected to a wear test on a MMW-1 vertical universal friction and wear machine with a test force of 1000N and a speed of 1000r / min. After 5 hours of wear test, the microhardness of the wear surface of the sample is HV1117. The sample changed from 2.8907g to 2.8921g and lost -0.048%, which means that the sample not ...

Abstract

The invention discloses a novel DAH medium-load rotary-type air compressor oil composition, a manufacture method thereof and application. 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 [0001] The invention relates to a novel DAH medium-load rotary air compressor oil composition and its preparation method and application. The composition is suitable for lubricating oil-cooled cylinder liners and rotors in cylinders of rotary compressors, especially suitable for lubricating low 1. Lubrication of medium-load screw air compressors, belonging to the technical field of materials. Background technique [0002] A rotary compressor is a volumetric compressor that uses the rotational movement of one or more rotors in the cylinder to produce a change in working volume to achieve gas compression. There are many differences between the working principle, lubrication system and the use of lubricating oil of rotary compressors and general reciprocating compressors. Among them, the oil-cooled compressor is the most widely used form. The lubricating oil is directly sprayed into the compression chamber of the cylinder for cooling, sealing and lubrication, ...
