Maintainance

Maintaining the hydraulic pump of a Doosan excavator is an important step to ensure its normal operation and extend its service life. Here are some recommended maintenance methods for the hydraulic pump of a Doosan excavator:

Regularly change the hydraulic oil: Hydraulic oil is the key to the normal operation of the hydraulic system. Regularly changing the hydraulic oil can prevent contaminants and impurities from damaging the hydraulic pump. Make sure to choose the hydraulic oil that is suitable for the excavator model and the working environment, and replace it according to the manufacturer's recommendations.
Clean the hydraulic oil tank: Regularly cleaning the hydraulic oil tank can remove impurities and sediments and maintain the cleanliness of the hydraulic oil. Before cleaning the hydraulic oil tank, always turn off the hydraulic system and use appropriate tools and cleaning agents to clean it.
Check the filter: The filter in the hydraulic system is an important component to prevent impurities from entering the hydraulic pump and other hydraulic components. Check the condition of the filter regularly, and replace it in time if it is damaged or blocked.
Filling points and lubriion: The filling points and lubriion points of the hydraulic pump are parts that require regular maintenance. Use the right amount of lubricant and lubrie regularly according to the instructions in the operating manual.
Regularly check the fasteners: The fasteners around the hydraulic pump should be checked regularly to ensure that they are in the correct tightening state. If they are loose or worn, they should be repaired or replaced in time.
Temperature control: Keep the temperature of the hydraulic system within the appropriate range. Too high or too low temperatures may have adverse effects on the hydraulic pump. Ensure the normal operation of the cooling system and avoid overuse of the hydraulic system.
Check for leaks regularly: Check the hydraulic system for leaks regularly. Leaks may cause hydraulic pump performance degradation and hydraulic oil loss. If leaks are found, they should be repaired immediately.
Please note that the above are only general recommendations, and specific maintenance methods may vary depending on the excavator model and manufacturer. It is strongly recommended to refer to the Doosan excavator's operating manual and maintenance guide for accurate maintenance information and recommendations. In addition, if more complex maintenance or repair work is required, it is recommended to seek professional technical support or consultation.
