Cavitation is one of the leading causes of premature centrifugal pump failure which manifests itself as excessive noise and vibration, performance deterioration and eventually seal, bearing and impeller damage.
Therefore, a robust understanding of cavitation phenomenon is essential for system designers and users who are dealing with this type of pump. This includes understanding the design factors that should be considered when selecting and sizing a centrifugal pump, knowing the deteriorating effect that cavitation can have on a pump’s functionality and understanding the ways to detect, avoid and sometimes manage the cavitation.
This webinar aims to provide participants with some basic knowledge and concepts to help them better understand this phenomenon, by covering the following topics:
- Definition of cavitation
- Fundamental design factors defining cavitation behaviour in centrifugal pumps, such as Net Positive Suction Head (NPSH), Cavitation Number (σ) & Suction Specific Speed (NSS)
- Ways to predict, avoid or manage the cavitation
Even though the focus of this webinar will be on the cavitation in centrifugal pumps, some of the concepts are general and can be applied to other types of rotodynamic pumps.
