Finite Element Analysis of Sealing Performance for Multi Cylinder Packer

摘要

Sealing performance of multi cylinder packer is analyzed by using finite element analysis method in this paper. The setting process is analyzed by apply different sealing load to the multi cylinder packer, and it is found that the different sealing load will cause the different gap between the rubber tube and the central tube in the packer. Thus, the position of the main seal in the multi cylinder packer is thus obtained.
