DETERMINATION OF THE QUALITY OF HYDRAULIC OIL BASED ON THERMOPHYSICAL CHARACTERISTICS

The article provides a brief description of hydraulic oils and their classification. The main modern requirements for working fluids widely used in hydraulic drives are described. The results of a study of the influence of the amount of pollutants on the temperature mode of the hydraulic drive are presented. The relevance of determining and monitoring wear products in hydraulic drives of forestry machines that affect safety and reliability is considered. The need for a detailed consideration of the proposed topic for the purpose of further study and development of a universal method of thermal diagnostics is substantiated.
