THEORETICAL STUDY OF THE PERFORMANCE OF "DRY" SEALS IN THE PRES-ENCE OF ROTOR VIBRATION


Cite item

Abstract

The article presents the results of monitoring the rotor vibration occurring in gas-pumping units. An assessment of the effect of vibration loads on seal leakage has been carried out. The maximum amplitudes and frequencies of vibration of rotors of gas-pumping units under operating conditions have been determined. A dynamic model of a "dry" seal is proposed, in which axial, angular and bending vibrations of the seal rings are realized. The theoretical definition of the rotor vibration parameters admissible for the operation of "dry" compaction is carried out.
