Vibration Analysis of Turbine
Gas and steam turbines are essentially similar mechanically, with gas turbines having the added complication of a combustion chamber. Gas turbine vibration signatures commonly contain a broadband vibration component caused by the combustion noise.
Turbine Diagnostics Turbines often exhibit a strong component at the so-called blade rate, which is the number of turbine blades times the RPM of the rotor. The magnitude of this component is dependent on the internal geometry of the unit. If this changes, as for instance by a cracked, warped, or pitted blade, the blade pass component in the vibration signature will change, usually for the worse.
The vibration Analysis on turbine gives information about, Unbalance or Misalignment in Turbine Vane, Flow Turbulence, Blade Rotation sound, Turbine Blade Damage, Rotor Clearance Problem, Rotor & Casing Misalignments, Rotor Rubs, and Torsional Vibration.
