AI Technical Summary
In traditional viscous dampers, the rubber sealing ring is prone to aging and wear, leading to unstable sealing. The spring compensation structure has a long ineffective stroke and is complex to assemble, affecting the service life and efficiency of the damper.
High wear-resistant POM material is used to replace the rubber sealing ring, and the piston displacement is compensated by the elastic deformation of the sealing face cover, simplifying the assembly process. The piston and cylinder are sealed by interference fit design, eliminating the traditional spring compensation structure.
It improves sealing stability and the effective working stroke of the damper, extends service life, reduces production and maintenance costs, and enhances response speed and efficiency.
