Excavator Cylinder Piston Seals

Precautions for the installation of hydraulic cylinder piston seals in excavators
1. The sealing of the oil cylinder piston should use products of reliable quality to ensure good sealing performance.
2.Before installing the oil cylinder piston seal, the seal and sealing groove should be cleaned to ensure that the sealing surface is free of impurities.
3. When installing the seal, the correct installation sequence and direction should be carried out according to the drawing requirements to ensure the correct installation of the seal.
4.When installing the seal, special tools should be used to avoid using sharp tools and hard objects to damage the seal.
5. When installing the seal, attention should be paid to whether the seal groove is damaged or worn. If so, it should be replaced or repaired in a timely manner.
6. When installing the seal, an appropriate amount of lubricating oil should be applied to avoid friction damage to the seal during installation.
7.When installing the seal, it should be ensured that the compression of the sealing ring meets the requirements to avoid excessive or insufficient compression leading to seal failure.
8.After installing the seal, a sealing test should be conducted to ensure that the sealing performance meets the requirements.
