Environment friendly energy-efficient heavy-load compression machine oil

Abstract

The invention provides environment friendly energy-efficient heavy-load compression machine oil, which comprises the following components by mass percentage: 90-95% of base oil and 10-5% of other additives. Metallocene poly alpha-olefins (mPAO), poly internal olefin (PIO) and dioctyl sebacate are composited as base oil of heavy-load compressor oil. One main component of the base oil of the compressor oil is dioctyl sebacate which has a sufficient raw material source, and the product is a reproducible resource with high economic benefit and social benefit, and the preparation technology is simple. Each physical and chemical index of the heavy-load compressor oil reaches the usage requirement, and the polyisobutylene can be blended with the product for producing a product which meets the performance requirements of L-DAC heavy-load compressor oil with viscosity grades as follows: N32, N46, N68, N100 and N150. The product is suitable for lubricating, cooling and sealing the cylinder and the crankcase of the middle and heavy-load piston compressor and the large-scale rotary compressor.

Description

technical field [0001] The invention relates to an environment-friendly and energy-saving heavy-duty compressor oil. Background technique [0002] Compressor is a general-purpose machine used to compress gas, increase gas pressure or transport gas, and has been widely used in refrigeration, petrochemical, gas transportation, civil engineering, urban gas pipeline network, national defense, medicine, textile, food, machinery Manufacturing, mining metallurgy, construction machinery and other fields. In recent years, with the enlargement of reciprocating air compressor equipment and the development of heavy load, high temperature, high pressure, and large flow operation, higher requirements have been put forward for the safety and reliability of the compressor. To ensure the safety and reliability of the compressor Work, lubrication is one of the important links. Since the compressor oil directly contacts the compressed medium, the pressure is high, and it is easily affected b...

AI Technical Summary

Problems solved by technology

When the working conditions are bad, there are still metal debris, which accelerates the oxidation of the compressor oil, increases the carbon deposit, and even leads to the risk of spontaneous combustion and explosion of the compressor oil.

To solve this kind of problem, the existing compressor oil (DAA, DAB) can no longer meet the requirements
