Monitoring of typical pumps and aerator in a water treatment plant - Case Study
Surface aerator:Vertical equipment, gearbox associated very high cost for wired solution, aggressive environment, very few visual and periodical inspections.
Centrifugal pump: Located underground in concrete basement, busy area, pipes and metal structure all around.
Effluent pump: Vertical equipment, remote location, integrate a bearing under water
Analyst diagnosis and spectrum justification: Bearing
We observed a vibration at 2,51 orders (30 Hz) relative to a bearing defect. The vibration amplitude is acceptable 1G Pk-Pk
