Maintenance
The excavator hydraulic pump is an important part of the excavator. Regular maintenance can extend the service life of the pump and ensure the normal operation of the excavator. The following are some maintenance recommendations for excavator hydraulic pumps:
1. Change hydraulic oil regularly: The normal operation of a hydraulic pump requires cleanliness and proper lubrication. Regularly changing hydraulic oil can prevent impurities and contaminants from damaging the pump. Follow the correct hydraulic oil change interval according to your excavator owner's manual or manufacturer's recommendations.
2. Check the hydraulic oil filter: The function of the hydraulic oil filter is to remove impurities and contaminants in the hydraulic system. Regularly check the condition of the hydraulic oil filter and replace it as necessary. A clogged filter will reduce the efficiency of the hydraulic system and increase the load on the pump.
3. Check the seals: The pump seals include O-rings, gaskets, etc. Regularly check the wear of these seals, and if they are found to be worn or damaged, they should be replaced in time to prevent leakage and reduced pump performance.
4. Check for leaks: Check the hydraulic pump and hydraulic system regularly for leaks. Leaks can cause the loss of hydraulic oil, reduce the efficiency of the system, and may cause other malfunctions. When leaks are discovered, they should be repaired promptly.
5. Pay attention to the working temperature of the hydraulic pump: too high working temperature will have adverse effects on the hydraulic pump. Ensure that the cooling system of the hydraulic system is working properly and avoid long-term overload operation to control the operating temperature of the hydraulic pump.
6. Clean the hydraulic pump regularly: Cleaning the hydraulic pump regularly can remove dirt and impurities attached to the pump and keep the pump clean. When cleaning, use an appropriate detergent and be sure to rinse thoroughly after cleaning.
7. Pay attention to the vibration and noise of the hydraulic pump: Abnormal vibration and noise may be a sign of problems with the hydraulic pump. Regularly check the vibration and noise of the hydraulic pump. If any abnormality is found, repair or replace it in time.
Please note that before performing any maintenance work, it is recommended to refer to the excavator's manual or consult a professional technician to ensure that correct methods and procedures are followed.
Theory
1. Heat dissipation and cooling: The fan pump generates airflow by rotating the fan, introducing the surrounding cold air into the engine area, and taking away the heat generated by the engine. This helps maintain the engine's normal operating temperature range and prevent overheating.
2. Coolant circulation: The fan pump of the excavator usually also contains a water pump, which is used to draw coolant (usually a mixture of water and coolant) from the engine cooling system and send it to the fan. The coolant dissipates heat when it comes into contact with the air and is then circulated back to the engine, continuing to reduce engine temperature.
3. Cleaning effect: The air flow of the fan pump can also help remove dust, sand and other debris around the engine. If these debris accumulate on the engine, they may hinder heat dissipation and affect the normal operation of the engine.
