The hydraulic system overheating mainly has these factors

When the excavator works normally, the hydraulic system overheating mainly has the following factors. First of all, the system structure design is unreasonable, the machining accuracy of parts is not up to standard, and the assembly is improper, for example, the matching nature of parts and components changes, which should have gap matching and become transition fit or even interference fit in the actual working process. The selected hydraulic tubing passes through fine, bending less than 90 degrees. Tank volume is too small and tank heat dissipation capacity is insufficient. If the quality of hydraulic components or improper operation of the system will also cause system heating.
