Functional use

The oil seal of the hydraulic system of the excavator plays a vital role in the normal operation of the excavator.
The main function of the oil seal is to prevent the leakage of hydraulic oil and ensure that the hydraulic system can maintain a stable pressure, so as to ensure that the various actions of the excavator are accurately and effectively executed.
Common materials for oil seals of hydraulic systems of excavators include rubber, polyurethane, etc., which have good oil resistance, wear resistance and high and low temperature resistance.
High-quality oil seals can effectively extend the service life of the hydraulic system and reduce the probability of failure. If the oil seal is damaged or aged, it may cause hydraulic oil leakage, making the excavator slow, weak, or even unable to work normally.
When choosing the oil seal of the hydraulic system of the excavator, it is necessary to consider factors such as the size, material, applicable working pressure and temperature range of the oil seal to ensure that it is perfectly matched with the hydraulic system of the excavator. At the same time, regular inspection and replacement of oil seals are also an important part of excavator maintenance.
