Abstract: The two-dimensional axisymmetric geometry model of hydraulic Glyd-ring seal was established by applying the ANSYS software, which was used to analyze the effects of two precompression finite element models, the axial push and the radial compression, that were used to simulate the sealing ring installation process, and the related simulation results were compared and studied. Firstly, the stress distribution differences of two FEA models were given. Secondly, the influences of compression rate and sealed pressure on the static sealing performance with the two FEA models were compared and analyzed. The results indicate that the effect law on the static sealing performance of the two FEA models is basically the same, and the stress distribution is basically similar, but there is a deviation in the prediction of the stress concentration parts of the seal ring, which shows that the stress concentration of the radial compression model is closer to the air side. In addition, the simulation results of the axial push precompression FEA model reveal that the chamfer of polytetrafluoroethylene ring near the oil side is easier to meet with wear, which is in consistency with engineering practice.
