Using nonlinear finite element method, the compression load deflection of the seal was analyzed and cross sectional shape of the seal was optimized.
利用非线性有限元法分析了密封条的压缩受力变形特性，根据结构力学原理对密封条横截面形状进行了优化。

At installation, insufficient compression of the sealing pad behind the carbon ring seal of the expander results in oil entrance to expander body and to the corresponding pipeline.
由于膨胀机碳环密封后面的密封垫片在安装时未被充分压紧，使膨胀机机体及相应管道进油。

The present study shows that there is a critical seal pressure which is only related to the compression ratio and the friction coefficient, but does not depend on the radius of the elastomer ring.
