Excavator seals are the core consumable parts to ensure the stable operation of excavators. They are widely used in key parts such as hydraulic systems, engines and rotary mechanisms, and play an important role in leakage prevention, dust prevention and oil insulation.
Its materials need to adapt to the harsh working conditions of the excavator. Common ones are nitrile rubber,
fluororubber, polyurethane, etc. Nitrile rubber has excellent oil resistance. Fluororubber can withstand high temperature and strong corrosive media, while polyurethane has high wear resistance and can cope with the friction loss of the reciprocating movement of the piston rod.
The failure of the seal will directly cause hydraulic oil leakage and pressure drop, resulting in slow and weak movement of the excavator, and even causing serious faults such as cylinder block and piston strain. Therefore, selecting the seals of the suitable model, regularly checking the aging and deformation, and replacing them in time is a key measure to reduce the failure rate of the excavator and extend the service life of the equipment.
