Mathematical Modelling of Dynamic System Rotor-Groove Seals for the Purposes of Increasing the Vibration Reliability of NPP Pumps
نویسندگان
چکیده
Groove seals are considered as hydrostatic bearings capable of effectively damping rotor vibrations. In order to determine the dynamic characteristics, a model rotor-groove system is considered. The radial forces and moments in groove had been estimated. Expressions joint radial-angular vibrations obtained. Formulas proposed for constructing amplitude phase frequency characteristics. An example calculating characteristics centrifugal machine presented. directions increasing vibration reliability NPP pumping equipment by purposefully rigidity determined.
