PROCEDURE FOR DETERMINATION OF RUNOUT OF REVOLVING ROTOR OF GAS CENTRIFUGE Russian patent published in 2011 - IPC G01M1/22 

FIELD: machine building.

SUBSTANCE: invention refers to procedures for determination of runout of revolving rotor of gas centrifuge (GC) by analysis of signal from inductive rotation sensor (sensor of rotation signalisation SR). Additionally, the procedure for determination of value of runout of the gas centrifuge rotor consists in measurement of duration of periods of a signal from the sensor of rotation signalisation and in distribution of periods by duration. On base of distribution there is found difference in durations of the longest and shortest periods and average duration of a period. Further, there is calculated value of runout by formula where A is value of runout, c is constant depending on design of the sensor, ΔT is difference between the longest period T_max and the shortest period T_min of signal from the sensor SR; ΔT=T_max-T_min; T_aver is average duration of period of a signal from sensor SR.

EFFECT: prediction of change of technical state of gas centrifuge in course of time; additional optimisation of repair term and reduced losses of operation time.
