Oil quality analysis

Thread Content

Dear sea friends: What are the common parameters for oil quality analysis? Are there any differences in the parameters analyzed for oils of different models and qualities (such as 150# machine oil and 46# hydraulic oil)? What is the water content------, -----=? It’s unqualified and can’t be used anymore? Can an oil filter only remove impurities?

Parameters: flash point, kinematic viscosity, moisture content, acid value, emulsification resistance, mechanical impurities, corrosion test, etc. Different oils require different analysis methods and frequencies; for N46 oil, only viscosity, moisture content, impurities, and flash point need to be analyzed. If it fails the tests, it can only be replaced
