| Abstract: | The leakage process of multilevel series seal is very complicated. Its leakage rule is important for design, leakage detection and sealing safety of multilevel series seal. As subject investigated, the mathematical models of the multilevel series seal were formulated. By means of mathematical analysis and numerical computation, the conclusion of the relationship of the leakage rate, quantum and time was disclosed. Simulation examples and experiment of 3-level seal systems are performed. That proves the theory for the multilevel series seal is correct. Finally, application methods of the leakage rule are generalized. |
