Maintenance

The excavator hydraulic pump is one of the key components of the excavator, and maintenance has an important impact on its normal operation and life. The following are some maintenance recommendations for excavator hydraulic pumps:

1Replace hydraulic oil regularly: The normal operation of the hydraulic pump requires clean hydraulic oil. Regular replacement of hydraulic oil can keep the hydraulic system clean and avoid damage to the hydraulic pump by sediment, impurities, etc.
2 Pay attention to the temperature of the hydraulic oil: the hydraulic pump will generate heat during work, and excessive temperature will have an adverse effect on the hydraulic system. Make sure the hydraulic oil temperature is within the normal range and avoid overheating or overcooling.
3. Check the seals of the hydraulic pump: Regularly check the seals of the hydraulic pump, including O-rings, sealing rings, etc., to ensure that they are intact. If there is wear or aging, replace it in time.
4. Check the filter of the hydraulic pump: The filter of the hydraulic pump can filter impurities and particles in the hydraulic oil and keep the hydraulic system clean. Check and clean or replace the filter regularly to ensure it is working properly.
5. Regularly check the oil seal of the hydraulic pump: The oil seal of the hydraulic pump plays a sealing role to prevent hydraulic oil leakage. Regularly check whether the oil seal is intact and replace worn or aging oil seals in time.
6. Pay attention to the working pressure of the hydraulic pump: Ensure that the working pressure of the hydraulic pump is within the normal range to avoid damage to the hydraulic pump due to excessively high or low pressure.
7. Clean the hydraulic pump casing regularly: Keep the hydraulic pump casing clean to prevent dust, sediment and other impurities from entering the hydraulic pump.
8. Carry out regular maintenance of the hydraulic pump: According to the usage of the hydraulic pump and the manufacturer's recommendations, regularly carry out repairs and maintenance of the hydraulic pump, including cleaning, lubrication, tightening bolts, etc.
Please note that before performing any maintenance and repair work, the operating instructions of the excavator and hydraulic pump should be carefully read and operated in accordance with the manufacturer's recommendations and requirements. If you do not have relevant technical knowledge and experience, it is recommended to seek help from professional technicians.
