What parameters should be tested for compressor lubricant?
Thread Content
What parameters should be tested for the lubricating oils of centrifugal compressors and reciprocating compressors, in addition to kinematic viscosity, moisture, and mechanical impurities?
Generally, the acid value is also analyzed; if the acid value exceeds the limit, it means the oil is damaged, its lubricating properties are poor, and it can cause equipment corrosion.
I remember there were seven indicators: residual carbon, viscosity, viscosity ratio, moisture, acid value, flash point, and demulsification time
Compressor lubricant – could you please recommend a few options, experts?
