I. What is an excavator repair kit?
The repair kit, also known as the repair kit or seal repair kit, refers to a set of parts that packages all the seals (such as O-rings, oil seals, gaskets, dust rings, guide belts, etc.) that need to be replaced during the repair of an assembly or part.
Core value: The repair package ensures the integrity and convenience of the repair, avoids the repeated procurement of maintenance personnel due to the missed purchase of a certain seal, improves the efficiency of repair, and ensures the matching and quality consistency of all seals.
II. The main contents of the repair package
A typical excavator repair package usually contains all or part of the following seals:
1. Dynamic seal:
Main seal: withstand the main working pressure to prevent oil leakage.
Dust ring: located on the outermost side to prevent dust, silt and moisture from entering the system.
Guide belt/support ring: usually made of wear-resistant plastic (such as polyformaldehyde POM), which is used to support the piston or piston rod to prevent direct metal contact and bias.
Special seals, gly coils, combination seals, etc.: special high-performance seals for piston and rod seals.
2. Static seal:
O-ring: used for static bonding surfaces such as end covers and valve blocks.
Gasket: such as a metal or composite gasket between the cylinder end cover and the cylinder.
3. Other accessories:
