Part Load Flow Phenomena and Excitation Forces in Centrifugal Pumpsected. The part load flow recirculation leads to a strong interaction between impeller, inlet, diffuser or volute and flow between impeller side plates and casing. This influences also the rotor vibration since preswirl to the labyrinths is affected by this interaction.

Analogy

Vibrations and Fretting Wearl and material point of view. Steels, copper, aluminium and titanium alloys are considered along with such materials as PMMA, polycarbonates or composites. Vibrations are shown to control velocity accommodation mechanisms.

Early Failure Detection by Spectrometric Methodsy. With the development of high-performance analysis techniques, efficient and flexible methods became available for all individual systems to be monitored. In the following, the most frequently used spectrometric techniques and their variants are described and their suitability for defect avoidance
