Mathematical modeling of centrifugal machines rotors seals as dynamic systems

Abstract

The possibilities of using axial and radial contactless seals as static and dynamic supports of the centrifugal machine rotor are considered. A model of the hydromechanical system rotor - groove seals has been built. Analytical relationships that describe the radial - angular oscillations of a centrifugal machine rotor in groove seals are obtained.
