AI Technical Summary
Existing sealing ring assemblies are prone to deformation when subjected to external pressure, especially permanent deformation under radial force, which affects sealing safety and installation stability.
It adopts a design of support ring, pressure ring and sealing ring. The support ring and pressure ring are provided with V-shaped grooves. The support part is inserted into the groove and fits against the groove wall. The support ring is inserted into the placement cavity and fixed. The support ring is made of hard material and stores lubricating oil through gaps and grooves. Heat dissipation holes are provided for heat dissipation.
It improves the installation stability and sealing effect of the sealing ring assembly, reduces the probability of deformation, and enhances sealing safety and convenience.
