During the use of hydraulic oil, it is inevitable that some impurities and moisture will invade, causing the hydraulic oil to deteriorate. The oil film of the deteriorated hydraulic oil is slightly insufficient to withstand the pressure of the working load, causing the metal surfaces to come into contact with each other, resulting in a sharp increase in friction and accelerating the wear of parts; The decrease in lubrication performance of hydraulic oil leads to wear on the internal tooth surfaces of hydraulic pumps and motors. What are the reasons for the deterioration of hydraulic oil?
1, Oxidative deterioration;
2, Mixing water and air during use;
3, Mixing with particulate pollutants.
1. Residual substances inherent in hydraulic equipment, such as impurities generated during manufacturing and assembly processes that have not been removed;
2. The oil pipes through which the oil flows and the oil drums storing the oil contain impurities that mix into the oil;
3. The harsh outdoor working environment in the field leads to the intrusion of various material particles into hydraulic equipment;
4. Hydraulic equipment invades pollutants during refueling, oil change, maintenance, and other processes;
5. Pollution caused by mechanical friction, deformation, and chemical reactions.
