Maintenance
Everyone should pay attention to the causes of hydraulic oil contamination in construction machinery!
Contaminants in the new oil
Although hydraulic oil is refined and processed under relatively clean environmental conditions, during transportation and storage, it may be contaminated by pipelines, oil drums and storage tanks, and some dust, sand, rust, moisture and other liquids may mix into the oil.
2. Residual contaminants in components and systems
During the processing, assembly and cleaning of hydraulic components and systems, some contaminants may remain due to incomplete cleaning work.
3. External contaminants
During the operation of hydraulic components and machinery, due to incomplete sealing of the oil tank, damage to the sealing and protective devices of components, and other reasons, some contaminants such as dust, sand, and moisture may invade from the outside of the system.
Contaminants generated inside the hydraulic system
During operation, the hydraulic system itself generates some solid particulate contaminants, including metal particles or rubber powder produced by the wear and corrosion of hydraulic components, as well as contaminants generated by the oxidation of oil, etc.
