Survey of pump and pump unit vibration

| 2023:934 | Åsa Collet, Penka Dinkova, Krister Larsson
A pump vibration problem is just a symptom of the wrong energy balance in the assembled pump system. Instead of being a reliable pump efficiently transporting fluid, the pump wears and uses its energy for unwanted vibrations instead.  As a result, the vibration from a pump must be investigated and analyzed in a preferred parallel multidisciplinary way to find the most suitable correction.

This project aims to collect the knowledge and experience of vibrations in pump and pump unit systems. The information is assembled in this report and can be used to increase awareness of which pump vibration problems that may arise and how to best avoid them when working with maintenance and quality assurance both during the commissioning phase of new equipment, as well as in a long-term operational perspective. The report is based on interviews with three Swedish and two Finnish nuclear power plants.
