Abstract

Analytical calculation technique and results of numerical and experimental investigations of two-stage face impulse seals with discrete supplying and with coaxial arrangement of stages are presented. As the common friction pair is divided in radial direction by discharge chambers into two sealing stages, the design of assembly is essentially simplified and its dimensions are decreased, keeping increased reliability and hermetic sealing. Mechanism of operation of such a seal is based upon impulse balancing of friction pair and creating of a guaranteed self-regulated gap. This simple, robust and compact design provides greater intrinsic reliability than traditional gas seal designs. The theoretical static and flow characteristics are compared with experimental results and coincidence within 5 % are obtained.
