Diagnostics of steam turbine rotors

Figure shows the testing results of the average pressure rotor of one of the turbines K-300-240 LMZ mounted on the Konakovo hydroelectric power station. It is seen on figure that maximum field Нр change is registered on the disk hub №28 between sides of steam inlet and outlet. The obtained result according to applying method witnesses about disk № 28 operation in conditions of significant axial vibrations.

Fig.1. The testing results of the turbine rotors.
