Rotor Sealings based on a Metal–Rubber Elastic Porous Material for Turbomachinery

Abstract

The problems of making efficient rotor seals for turbomachinery has been outlined. A design of a seal with a sealing element made of metal-rubber elastic porous material has been proposed. A model of thermal processes in this seal during contact interactions with the rotor has been developed. The need to determine the range of changes in the parameters of the structure of the metal-rubber material, which makes it possible to use it as a sealing element for rotor seals made using existing technologies for structural damping systems, has been revealed. The results of studies of friction processes have been presented and the types of wear of the metal-rubber material in the rotor seal have been determined.
