Metal Seals: Results of a Theoretical and Experimental Study of Their Elastohydrodynamic Lubrication.

Abstract

This Report describes an experimental and theoretical study of elastohydrodynamic lubrication in reciprocating metal seals. Their lubrication was not satisfactory under all conditions, and the aim of the work was to gain a fundamental understanding of the hydrodynamic conditions between the seal and counterface to determine why this was so. A rig was constructed which enabled simultaneous measurement of pressure distribution and film shape under a seal. On the theoretical side, solutions of the elastohydrodynamic equations are given and compared with the experimental results. The Report concludes with a discussion of the physical factors responsible for the unsatisfactory behaviour of the seals; some suggestions are made as to how these might be overcome. (Author)
