Air compressor lubricants analysis of anti-coking

Air compressor oil 2020 - coking analysis 09 - 29 coking is due to a series of air compressor oil caused by chemical changes. Lubricating oil belongs to organic compounds, mineral oil, for example, the main group is divided into various hydrocarbons ( Points of alkanes, aromatic hydrocarbons, cyclanes, etc. ) , heat, oxygen, light hydrocarbon compounds oxidation reaction happens, thermal contact, the higher the intensity of oxygen, the oxidation reaction speed, the more intense. Oxidation can make the molecular chain rupture, crosslinking, likely also no argument chain and crosslinking can make hydrocarbons generated properties change. In the practical application of oil viscosity increase, acid value increase, color change, insolubles, such as increased when the depth of oxidation reaction oil viscosity increase beyond a certain range, created a coking phenomenon. Different nature of the air compressor oil oxidation reaction properties change is different, in practice, most of the screw air compressor oil coking is due to the use of inferior mineral oil and the captain of the air compressor running under the high temperature time. Compressor coking picture how to prevent air compressor lubricants coking? 1, please follow the rules of the air compressor equipment oil. Under the working conditions of some bad situation, should be appropriate to shorten product time. Before every oil change, should first will be clean air compressor oil, prevent sundry, coking clogging oil. 2, please use the original air compressor parts and guarantee the quality of parts. 3, to keep the cooling system heat flow. To keep the cooler fin surface clean chillers, ensure good heat dissipation. Water chilling unit to ensure the supply of cooling water, every six months or a year to open the cooler for inspection, and clean up the scale, make processing of descaling maintenance, to avoid bad air compressor cooling, avoid air compressor running at high temperature for long time, high temperature damage to oil is very huge. 4, the use of synthetic compressor oil. Synthetic lubricating oil has excellent thermal and chemical decomposition resistance, can prevent the rotation of the compressor parts in the case of high continuous operation produce sediment. （ Source: Rio showed circle)
