A vibration cavitation sensitivity parameter based on spectral and statistical methods

作者：

Highlights：

• Octave band analysis and PCA used on RMS velocity to obtain key indicators.

• Mahalanobis distance is used to set thresholds since data is normally distributed.

• Pump health separated into no cavitation, incipient, and fully formed condition.

• Method works on a range of types and sizes of centrifugal pumps.
