| Zusammenfassung: | The invention discloses a device for online measuring shaft diameter absolute vibration of a rotor of a steam turbine generator unit. The device comprises a magnetometer base arranged on a bearing boxof the steam turbine generator unit. A testing mechanism for measuring the shaft diameter absolute vibration of the rotor of the steam turbine generator unit is arranged above the magnetometer base.The testing mechanism is slidingly arranged in the radial direction of the rotor through a supporting frame, and the bottom end of the supporting frame is fixedly arranged on the magnetometer base. The testing mechanism comprises a vibration testing rod slidingly arranged on the supporting frame, and a vibration testing instrument connected to the top end of the vibration testing rod in an abutting mode. A direct contact method is adopted for online measuring the shaft vibration of the rotor of a steam turbine generator, interference of external environments such as electromagnetism is avoided, measured data is accurat |
