Structural Design and Finite-Element Analysis of Packing Seal with Self-Adaption and Resilience

Abstract

For lack of structure rigidity foundation and radial force diminishing exponentially with the distance of gland, a newly packing sealing structure with opening and hollow metal ring supporting is designed. Through finite element analysis, it comes out that the disadvantages are divided adding effect of high pressure resistant. The radial force is increased,preload is reduced, and the mechanical seals can be replaced under certain condition.
