Control system for adjusting the bearing oil temperature in order to minimize the rotor vibrations

摘要

The invention relates to a control system for reducing the rotor vibrations, in particular their variance, in a shaft train, in particular turbine train in which the temperature of the bearing 6 of the shaft is measured and the bearing oil supplied to the bearing 8 is set to a temperature as the output in an assignment for minimized rotor vibrations with the measured temperature of the bearing is assigned as an input variable. The assignment can be given for example by an initial measurement of the rotor vibrations or a self-learning system. The invention entails a narrowing of the variance of the rotor vibrations.
