ABSTRACT

The unit parameters growth of centrifugal machines requires solving the problems of effective media sealing. In addition to sealing itself, sealing systems affect the vibration safety of equipment. In order to harmonize the sealing functions and increase the dynamic stiffness of the centrifugal machines rotors, an algorithm and methods for modeling complex sealing systems have been developed. Examples of modeling of rotary machines complex sealing systems with high parameters are given. It is indicated that the development of complex sealing systems should be based on the configuration of composite seals in order to achieve harmonization between sealing and vibration reliability.

KEYWORDS
