Maintainance

Maintaining and servicing the hydraulic pump of the excavator is an important step to ensure the normal operation of the excavator and extend its service life. Here are some common suggestions for maintaining and servicing hydraulic pumps:

Replace hydraulic oil regularly: Hydraulic oil is an important factor for the normal operation of the hydraulic pump. Depending on the frequency of use and working environment of the excavator, it is necessary to replace the hydraulic oil regularly. Make sure to use the appropriate hydraulic oil and replace it according to the recommendations of the excavator manufacturer.
Check the hydraulic oil filter: The function of the hydraulic oil filter is to filter impurities and contaminants in the hydraulic oil. Check and clean or replace the hydraulic oil filter regularly to ensure that it works properly. Depending on the usage, more frequent inspections and maintenance may be required.
Check for leaks regularly: Check the hydraulic pump and hydraulic system for leaks. Leaks may cause the performance of the hydraulic pump to deteriorate or damage other hydraulic components. If leaks are found, they should be repaired in time.
Keep the hydraulic system clean: Clean the surrounding environment of the hydraulic pump and hydraulic system regularly to prevent dust, mud or other impurities from entering the system. This can be achieved by cleaning with high-pressure gas or detergent.
Check the hydraulic lines and connectors: Check the hydraulic lines and connectors regularly for wear, looseness or damage. Ensure the tightness and sealing performance of the lines and connectors.
Follow the manufacturer's maintenance schedule: Perform regular maintenance and servicing work according to the maintenance schedule and recommendations provided by the excavator manufacturer. This includes lubriing key components of the hydraulic pump, checking fasteners, adjusting tension, etc.
Please note that the above recommendations are for reference only, and specific maintenance and servicing requirements may vary depending on the excavator model and manufacturer. To ensure proper maintenance and servicing, it is recommended to refer to the excavator's user manual or consult a professional excavator repairman.
