Design of fluid dynamic pressure sealing
摘要
Abstract
Based on the finite element Matlab software platform, the numerical simulation anal-ysis and calculation of fluid dynamic pressure seal were carried out with computer, and the relation-ship of the fluid dynamic pressure sealing ring logarithmic spiral groove radius and spiral angle with the fluid dynamic pressure sealing opening force and leakage rate were studied. The design criterion of the hydrodynamic pressure seal was obtained. The process specification of laser marking etching loga-rithmic spiral groove was got in the laser marking process experiments. The logarithmic spiral groove moving ring made with this technology specification can meet the design requirements. The running test results of fluid dynamic pressure sealing medium show that the dynamic pressure sealing finite element numerical simulation analysis and calculation of Matlab computer are reasonable, and the design and process specification of the fluid dynamic pressure seal are correct and effective.关键词
