The working condition of the excavator cylinder is very bad. The main performance is as follows: the working pressure of the hydraulic system is large; the impact pressure is relatively high; the lateral load is large; the working temperature and the moving frequency are relatively high. Therefore, the performance of the excavator cylinder will have a direct impact on the quality of the entire machine.
Main cause of leakage
Selection of seals
1. The pressure is too high and the seal is too hard to be extruded into the metal groove.
2. the sealing material and the medium are dissolved, and the seals are softened or dissolved.
3. seals used in the condition of high temperature, sealing material is carbonized.
4. low temperature leads to sealing material hardening, shrinkage and leakage.
5. Using too high linear speed leads to heating, dry grinding, carbonization and leakage of seals.
6. Poor lubriion in service condition leads to wear and leakage of seals.
7. The cavity used is subjected to vibration and causes leakage.
8. Leakage is caused by wear of seals caused by dust.
