Maintenance
1. Replace hydraulic oil regularly: Hydraulic oil plays an important role in lubriion and sealing in the excavator hydraulic system. Regularly changing the hydraulic oil can ensure the normal operation of the hydraulic pump. Follow the manufacturer's recommendations, use a suitable hydraulic oil, and follow the appropriate change intervals.
2. Check the hydraulic oil filter: The function of the hydraulic oil filter is to filter impurities and contaminants in the hydraulic oil to prevent them from entering the hydraulic pump and other hydraulic components. Check and replace the hydraulic oil filter regularly to ensure it is working properly.
3. Check the seals: The pump seals, such as O-rings and sealing rings, are crucial to the normal operation of the hydraulic pump. Check these seals regularly to make sure they are intact. If any wear or damage is found, replace it in time.
4. Check for leaks regularly: Leakage is one of the common problems in hydraulic systems. Regularly check the hydraulic pump and various connection points of the hydraulic system to ensure that there are no leaks. If leaks are found, they should be repaired promptly.
5. Keep the hydraulic pump clean: Keeping the hydraulic pump and its surrounding environment clean can prevent dust, impurities, etc. from entering the inside of the pump, thereby reducing pump wear and failure.
6. Check pressure and temperature regularly: It is very important to monitor the working pressure and temperature of the hydraulic pump. Ensure that the hydraulic pump operates within its normal operating range and avoid exceeding rated pressure and temperature.
