What will happen if the hydraulic oil temperature of the excavator is high

As the temperature gradually rises, many users report that the hydraulic oil temperature of the excavator is high. If the high temperature of hydraulic oil is not handled in time, it will cause internal leakage of hydraulic pump, main control valve and various working devices. If it is serious, it must be repaired or replaced. This article will summarize the changes when the hydraulic oil temperature of the excavator is too high.
1. The oil viscosity decreases. This will make the system hot and form a vicious circle.
2. High oil temperature will accelerate oil oxidation. It forms colloidal substance and blocks the small hole of the element. Make the hydraulic components fail or get stuck, and finally make the excavator unable to work.
3. Rubber seals and other hoses are aging and invalid.
4. Increase the wear of oil pump and hydraulic valve, even damage.
