Permissible unbalance (imbalance) Calculator - Operational Data Turbine

  • This Calculator should be used as a reference scenario.
    It will simply tell you in what range the Unbalance Level should be expected and if values provided may or may not be reasonable.

     

  • It could be shown in the past that a value provided by the Manufacturer, is close to or nearly matches the  ISO 1940-1 value limit and is therefore a suitable substitute.
     

  • For instance :
    1MW+ GB Turbine      OEM 250kg*m   vs    ISO1940-1 257.41 kg*m
    1MW+ GB Turbine      OEM 330kg*m   vs    ISO1940-1 353.60 kg*m
    2MW+ GB Turbine      OEM 650kg*m   vs    ISO1940-1 569.69 kg*m
    2MW+ GB Turbine      OEM 500kg*m   vs    ISO1940-1 592.04 kg*m
    1MW+ DD Trubine      OEM 60kg*m     vs    ISO1940-1 86.68 kg*m
     

  • In general a value provided by the manufacturer would overrule any limit established by ISO 1940-1!!!
    ISO 1940-1 is not a law or binding standard ! Turbine design features may allow for higher values.
