What will happen if the quality of screw air compressor oil is not good?

Usually screw compressors need to be maintained after more than 2000 hours of operation. Air compressor oil is an essential part of the maintenance process, while air compressor oil has poor quality, many impurities and high viscosity. Easy to cause, air compressor oil shortage. The displacement of the bearing bush causes the internal oil circuit of the air compressor to be blocked, and the bearing bush and the connecting rod bush are strained or the matching clearance is too small. It is easy to cause the main shaft of the belt-driven air compressor to lock, and the bearing bush or connecting rod bush of the gear-driven air compressor to be abnormally loose.

The main components of air compressor oil are lubricating oil and base oil. The lubricating oil base oil is mainly divided into two categories: mineral base oil and synthetic base oil. The chemical composition of mineral base oil for air compressor oil includes high boiling point, high molecular weight hydrocarbons and non-hydrocarbon mixtures.

The main production processes of lubricant base oil for air compressor oil are: atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrogenation supplementary refining. According to the quality and performance requirements of the screw air compressor lubricating oil, careful selection of additives, careful balance, and reasonable deployment are the key to ensure the quality of lubricating oil.
