Description: TOUCHDOWN PUMPS
TOUCHDOWN PUMPS
Abstract
Two facilities with two different pump types used vibration and modal analysis to diagnose mechanical and hydraulic issues with their infrastructure. The modal and vibration analysis of a 227 ML/d (60mgd) two-stage vertical end suction resulted in resolving an intermediate bearing support structure issue, but uncovered other hydraulically induced vibration issues which will require additional investigation and study to resolve.A vibration analysis of a vertical mixed flow 98 ML/d (26 mgd) effluent pumping station revealed that the newly rebuilt and modified pumps exceed the Hydraulic Institute Standards for vibration. Modal analysis was utilized to develop a satisfactory operating solution for the facility.
