How to maintain the shock absorber hydraulic system? Proper use and maintenance of hydraulic tools are key to ensuring their performance and lifespan. Adhering to usage guidelines, keeping tools clean and lubricated, and performing necessary repairs and maintenance can enable hydraulic tools to achieve optimal performance.

Maintenance methods for hydraulic shock absorbers:
1. Cleaning and filter replacement
The cleanliness of hydraulic systems is very important, as impurities and pollutants may cause system failures and accelerated wear. When maintaining the hydraulic system, the first thing to pay attention to is the cleanliness of the equipment and regularly replace the filter element. This includes the sealing rubber rings of the oil suction and return filter elements, as well as the air filter.

2. Inspection and replacement of hydraulic oil
Hydraulic oil is the lifeline of hydraulic systems, and its quality and cleanliness directly affect the efficiency and lifespan of the system. It is recommended to check and replace the engine oil every 500 hours or at most every three months, and regularly clean the inlet filter of the oil pump to check whether the hydraulic oil is acidified or contaminated by other pollutants.

3. Check the system pressure and sound
Check the actual working conditions of the hydraulic system, including system pressure, speed, oil volume, leakage, vibration, etc., to see if there are any problems. In addition, it is also important to listen to the sound of the hydraulic system, such as impact noise, pump noise, and abnormal sounds, which can help determine whether the hydraulic system is working properly.

4. Check the seals and fasteners
Check if the seals of the hydraulic system have been replaced and if all force screws are regularly tightened to prevent loosening. When the seal fails, it should be replaced in a timely manner to prevent air from entering the hydraulic system and oil leakage.

5. Check the cooling system
The maintenance of the cooling system cannot be ignored, and the fins of the radiator should be cleaned regularly to prevent them from being blocked by dirt and affecting the cooling performance. For hydraulic pipelines, they generally do not need to be replaced if they are not damaged or burst.

6. Check the use and maintenance of hydraulic tools
Before using hydraulic tools, ensure that the hydraulic oil in the hydraulic system is clean, free of impurities, and maintains an appropriate oil level. During use, it is necessary to regularly check the quality and level of hydraulic oil, and replace or add new hydraulic oil if necessary. At the same time, attention should be paid to the smoothness and continuity of the operation, avoiding overly rapid movements or pressure changes.
