Application of the Wavy Mechanical Face Seal to Submarine Seal Design.

Abstract

In this report the results of theoretical and experimental investigations on the effects of waviness on mechanical seal performance are presented. In addition, the design techniques, design, and test results for a nine-wave small scale submarine seal are presented. The nine-wave seal has been shown to operate satisfactorily in preliminary testing. Problems with fabrication, stiffness, bonding, and oil system sealing were encountered and solved. Test results show friction to be somewhat higher than predicted. Leakage is very low. Further tests are being conducted. Further testing on balanced parallel face seals is reported. Details of test machine modifications required to operate in a submarine environment are given. Progress was made on solving the general problem of determining the precise contact pattern of two seal rings pressed together. This problem is important in assessing seal leakage problems. A new, general, coupled (in- and out-of-plane), ring finite element was developed and checked. Simple beam contact problems were solved using finite element methods. The final solution requires combining the finite element and the contact problem.
