Hydraulic oil is a very important industrial raw materials, and its quality even affects the overall life of the hydraulic system, so some of the hydraulic testing is very important, but what is the hydraulic oil testing standard？
A hydraulic system of construction machinery
Routine testing standards
For hydraulic oil physical performance indicators: viscosity, viscosity index, water, flash, solidification and pour point, mechanical impurities, insoluble matter, spot test, oxidation resistance, anti-emulsification, anti-foam, anti-wear and extreme pressure performance.
Important chemical property index: total acid number, total base number, anticorrosion, antirust, chemical stability and additive element analysis.
The quality of hydraulic filter directly affects the life of hydraulic system
