Principal research areas on mechanical face-seals
Abstract A critical review of world literature on radial face-seals is presented in order to further understanding of seal operation and to obtain some elements of a design method for optimization of their performance. The principal areas examined are hydrostatic, hydrodynamic and boundary lubrication of the faces, and in particular cavitation and the influence of different constructive parameters on the dynamic behaviour of these seals.
A STATISTICAL REVIEW OF MECHANICAL SEAL FAILURES IN PROCESS PLANT PUMPS
Statistical results for about 5000 failures in two large petrochemical plants are presented in terms of life distributions and Weibull plots. A digest of some previous statistically based analyses is included with some comparisons with the new data.
A Theoretical Analysis of the Twin-Land Type of Oil-Control Piston Ring:
Cyclic variations of the important operating characteristics of the twin-land type of oil-control ring have been analysed by considering radial and torsional equilibrium of the ring cross-section. ...
