Download Optimization of the Geometry and Flow of a Contactless Gasket

The purpose of this paper is to demonstrate ways to optimise the geometries and the flow- conditions of a contact-less gasket, which is operated with a liquid media. One of the most important points is the geometry of the feeding-lines and the annular groove which conducts the sealing- media into the annular gap, which is in direct contact with the media which is to seal. In addition to the different measurements the current of the sealing- media is also essential. The flow of the sealing- media which flows in longitudinal direction of the annular gap toward the blocking area is also influenced by the relative movement of the shaft and housing. It will be shown that the different flow-effects and velocities of the sealing- stream are important to generate a homogeneous flow.
