How to Completely Replace Excavator Hydraulic Oil

The lifespan of hydraulic oil in excavators is typically 4000-6000 hours, requiring replacement every two years. However, unlike engine oil or gear oil, only about half of the hydraulic oil in the excavator's hydraulic system is in the hydraulic oil tank, with the other half distributed throughout the pipes, pumps, valves, cylinders, and motors. Simply replacing the hydraulic oil in the tank would result in mixing old and new oil. So how can hydraulic oil be completely replaced? First, gather...

The Cause of Carbon Deposition in Excavator Engines

The Cause of Carbon Deposition in Excavator Engines

Firstly, let's discuss what carbon deposition is. Carbon deposition is actually the product of incomplete combustion. When the engine is operating, unsaturated olefins and resins in the engine oil and fuel will deposit under high-temperature conditions due to incomplete combustion. This black, charred substance is often referred to as carbon deposition, which can be divided into valve, combustion chamber carbon deposition, and intake pipe carbon deposition. Why does the excavator engine accumulate...
