For this reason, it’s important to understand the parts and how they operate.

The cause of the failure can often be attributed to how these parts function together.

21.  What do you mean by friction in excavator hydraulic pars?


Friction means that there will be some resistance to overcome when the machine operates, which results in heat generation and power loss.

Excavator hydraulic parts see many of their motions in a vertical plane, with little through movement.

The valve components have much internal frictional resistance, as do the cylinder block and the piston rod.

Between these stiffer parts are the fluid passage and the sealing faces, which move relatively freely.

Friction produces heat, causing the hydraulic fluid to expand and affecting its viscosity.

Hydraulic fluid that has sustained high friction levels can become gel-like and lose any ability to lubricate effectively.

If you’re noticing unusual high pressures or strange noises coming from your excavator hydraulic parts, it may be time for a change in hydraulic oil.


22.  What is the working principle of excavator hydraulic parts?


The working principle of various hydraulic excavator parts is based on the principle of hydraulics.

The working principle of excavator hydraulic parts is that the engine drives the input shaft and the input shaft through the torque converter transmission to drive the right and left side hydraulic pump, which provides power to the hydraulic fluid to pressure the various hydraulic components constantly.
