Abstract
The article presents the results of an experimental study of "dry" seals in the presence of rotary vibration. The descrip-tion of the dynamic stand measurement system is given. An assessment of the influence of vibration loads on leakage through the seal and an analysis of the influence of radial displacement and shaft misalignment on the operation of a "dry" seal are carried out. The analysis of the cause of the vibration defect is presented. The permissible values of the vibration amplitudes of the rotor of the gas pumping unit have been determined.
