Ultrasonic Technique for Assessment of the Rim Tightness of Hydro Generator Rotor

Ultrasonic Technique for Assessment of the Rim Tightness of Hydro Generator Rotor

At the hydroelectric unit No. 11 of the Nizhnekamsk hydroelectric power plant, the filling wedges of a rotor were investigated by ultrasound in the free state, after “cold” tight shrinking, after “hot” tight shrinking, and after 3000 and 8000 hours of operation. The ability to evaluate the rim tight...

Zusammenfassung:At the hydroelectric unit No. 11 of the Nizhnekamsk hydroelectric power plant, the filling wedges of a rotor were investigated by ultrasound in the free state, after “cold” tight shrinking, after “hot” tight shrinking, and after 3000 and 8000 hours of operation. The ability to evaluate the rim tightness of the rotor based on data on the redistribution of compression efforts in the wedges is demonstrated.
