Maintenance
1. Regularly replace hydraulic oil: Hydraulic oil is an important
part of the hydraulic system. It is very important to regularly
replace and maintain the cleanness and proper viscosity of the
hydraulic oil. Regularly check and replace hydraulic oil according
to the excavator manufacturer's recommendations, ensuring you are
using the correct specifiion and brand.
2. Regularly check the quality of the oil: Regularly check the
quality of the hydraulic oil, including checking for moisture,
impurities and contaminants. Use appropriate oil filters and oil
analyzers to ensure the quality of your hydraulic oil is up to
standard.
3. Check the seals of the hydraulic pump: The seals of the
hydraulic pump (such as O-rings, sealing rings, etc.) may be worn
or damaged during operation, causing hydraulic leakage. Regularly
inspect and replace hydraulic pump seals to ensure good sealing
performance.
4. Check the filter element of the hydraulic pump: The filter
element of the hydraulic pump is used to filter impurities and
particles in the hydraulic oil. Regularly check and replace the
filter element of the hydraulic pump to ensure normal hydraulic oil
flow and protect the hydraulic pump.
5. Pay attention to the temperature of the hydraulic pump:
Overheating of the hydraulic pump may affect its performance and
life. Ensure that the cooling system of the hydraulic pump operates
properly and avoid excessive operating temperatures.
6. Regularly check the vibration and noise of the hydraulic pump:
Abnormal vibration and noise may indie problems with the hydraulic
pump. Regularly check the vibration and noise of the hydraulic pump
and deal with any abnormalities in a timely manner.
