Problems solved by technology

In addition, part of the lubricating oil mixed in the compressed gas will be catalyzed by the cooling water and the copper tube in the cooler, causing the lubricating oil to age and deteriorate.
The long-term serious oxidation of lubricating oil will form carbon deposits in the exhaust valve and exhaust pipeline system, which will not only hinder the normal operation of the exhaust valve, increase the exhaust temperature and reduce the function of the compressor, but also cause compressor failure. main cause of explosion

Abstract

The invention relates to a synthetic hydrocarbon air compressor oil composition and its preparation method and application, and belongs to the field of material technology. The composition is composed of the following components in parts by weight: synthetic hydrocarbon air compressor oil 70-80, 8-12 pyrope, 10-13 fayalite, 1-3 magnesium-zinc-yttrium alloy, 1-2 lithium dodecyl hydroxystearate, the beneficial effect of the present invention is that the surface of the sliding part in the air compressor can be quickly Form a super-hard, corrosion-resistant wear-resistant layer. The hardness of the wear-resistant layer is 1125-1200Hv, the temperature resistance is 2200°C (destruction temperature), and it does not corrode in high humidity and acid-base media. The friction coefficient of sliding parts also reaches 0.001 ~0.003, is a very smooth mirror effect.

Description

technical field [0001] The invention relates to a synthetic hydrocarbon air compressor oil composition and its preparation method and application, belonging to the field of material technology. Background technique [0002] The working characteristic of the compressor is to compress the gas and do work. The larger the compression ratio, the higher the temperature rise, and the internal lubricating oil is usually in contact with the high-heat metal surface in the form of mist, which is easily heated and oxidized. The oxidation rate of lubricating oil is proportional to the oxygen partial pressure. The lubricating oil inside the air compressor is more likely to oxidize than it is in the atmosphere when it is in contact with high-pressure air. In addition, part of the lubricating oil mixed in the compressed gas will be catalyzed by the cooling water and the copper tube in the cooler, which will promote the aging and deterioration of the lubricating oil. The long-term serious ...
