The impact of multi-gap seals on rotor dynamics
Journal Title: Журнал інженерних наук - Year 2017, Vol 4, Issue 1
Abstract
The research relevance of multi-slotted seals is of practical significance for increasing vibration-reliability of centrifugal pumps. This paper presents the model of a single-disk rotor with seals. The forced radial rotor vibrations are determined taking into account the linearized inertial, damping, gyroscopic, positional, and circulating forces operating on the impeller from the liquid flow side in the annular seals. A theoretical analysis was supplemented with a numerical example, the amplitude-frequency and phase characteristic are presented.
