Abstract
This case study refers to resonance with vertical pumps. Vibration problem occurring after the inverter was installed for speed control. Its problem was appeared any revolution under rated speed. Vibration data was acquired during normal operation and transient state. We examined FRF on its resonance in field and also analyzed a result by finite element method. There was carried out the retrofit in field which was based on these results for solving problem.
