Hydraulic Oil Replacement in Excavators

Hydraulic Oil Replacement in Excavators

An excavator's hydraulic oil tank typically contains half of the hydraulic oil required for the entire hydraulic system, with the remaining half distributed across the hydraulic pump, motor, multi-way valve, hydraulic cylinders, and various pipelines. When changing the hydraulic oil, merely replacing the oil in the tank without addressing the entire hydraulic system results in a mere mixture of old and new oil. Combining different hydraulic oil brands can further lead to oil degradation. Preparation...
