Abstract
The paper deals with forced vibrations of centrifugal pump rotor taking into account the random variation of the annular seals parameters in the process of operation under action of random imbalance. The method of spectral resolutions to obtain probabilistic characteristics of vibration velocity and vibration acceleration of center of the masses of rotor model in annular seals was used. Evaluation of the influence of random variation of the parameters of the “rotor-seal” system in the process of pump operating on rotor stability is made.
