During the use of hydraulic oil, it is inevitable that some impurities and water will invade, so that the hydraulic oil will deteriorate. The oil film of the deteriorated hydraulic oil is not light enough to withstand the pressure of the working load.
The force causes the metal surfaces to contact each other, resulting in a sharp increase in friction and accelerated wear of the parts; the decrease in the lubricating performance of the hydraulic oil causes the internal gears of the hydraulic pump and hydraulic motor to
Maxillofacial wear. What is the reason for the deterioration of hydraulic oil?
1. Oxidative deterioration;
Two, mixed with water and air during use;
Three, mixed with particulate pollutants.
1. The original residual substances of the hydraulic equipment itself, such as impurities produced during the manufacturing and assembly process that have not been completely removed;
2. The oil pipe through which the oil flows and the oil tank in which the oil is stored contain impurities that are mixed into the oil;
3. The harsh environment of open-air work in the field causes various material particles to invade the hydraulic equipment;
4. Hydraulic equipment invades pollutants during refueling, oil change, maintenance, etc.;
5. Pollution from mechanical friction, shape and chemical reaction.
