Concepts of Sealing Mechanism of Rubber Lip Type Rotary Shaft Seals
H. Müller. Proceedings of the 11th International Conference on Fluid Sealing, page 698–709. London and New York and USA, Elsevier, (1987)59.
Abstract
It is well known that a normally tight rotary lip seal leaks permanently when it is eonversely installed. The reverse leakage obviously is the result of a hydrodynamic pumping mechanism which, at regular installation of the seal, creates a dynamic sealing mechanism.
A number of different physical processes which in principle could create the pumping mechanism are discussed. Two of the concepts relate to adeviation of the tangential shear flow induced by definite microstructures of the rubber surface. Based on small deviations of shape or position of the seal edge a third concept considers very small relative reciprocating motions between shaft and seal. Probably in practice the sealing mechanism is determined by various physical processes at the same time.
