- Scope
- This standard specifies the measurement method and evaluation criteria for the radial vibration of the shaft of the multi-rotor system of a large turbo-generator set installed on land. This standard applies to large-scale turbogenerators installed on land with a rated power greater than 50MW and a rated speed range of 1500-3600r/min. Generally speaking, the vibration state of a turbogenerator set should be evaluated from two aspects: the vibration of the rotating shaft and the vibration of the bearing seat. For the general principles of shaft vibration measurement and evaluation involved in this standard, refer to GB 11348.1-89. This standard is applicable to the measurement and evaluation of the vibration of the shaft of the turbine generator set at or near the bearing under normal working conditions. This standard is not applicable to the evaluation of the vibration state of the shafting under unsteady working conditions, such as starting, stopping, overspeed and passing the critical speed. This standard does not apply to the measurement and evaluation of the torsional vibration and axial vibration of the turbogenerator shaft system.
