Oil Analysis
No other industrial and manufacturing equipment drive technology provides such high power density, durability and resistance to harsh environmental conditions as hydraulics. However, this is only true as long as the hydraulic fluid is not contaminated.
Oil Analysis
Kinematic viscosity
According to STN EN ISO 3104+AC
The viscosity of the fluid is a very important parameter for the service life of the equipment (lubricity). The analysis is carried out by heating the liquid accurately to a temperature of 40 °C and measuring the amount of liquid flowing through the calibrated capillary as a function of time.
Oil Analysis
Mechanical impurities
According to NAS 1638 and ISO 4406.
Mechanical impurities fundamentally affect the service life and reliability of hydraulic equipment. The analysed fluid is filtered through filter paper and the microscope image is compared with a standard to determine the fouling class. The presence of resins is detected by a comparative method of staining in the vicinity of the impurities.
Oil Analysis
Water content
According to STN EN ISO 12937
The presence of water in the oil impairs its lubricity and accelerates chemical ageing, foaming, formation of water emulsions, sludges, and resins. A potentiometric titrator is used to determine the water content. The principle of the method is an oxidation-reduction reaction in which chemical compounds react with water in the oil sample.
