Vibration of centrifugal fans
Thread Content
Our factory has a fan mounted on a frame, with shock-absorbing devices at its base. During testing, the vibration levels are 24.6 mm/s horizontally and 26.7 mm/s vertically when the fan is under load; these values rise to 25.4 mm/s horizontally and 28.5 mm/s vertically when it isn’t under load. The base of the fan has been reinforced and balancing has also been done, but the vibration levels still remain high. What could be the other possible causes? Please help me figure this out
No, it’s the vibration value when driving
The main reasons for the vibration are: 1. poor dynamic balance, 2. an unstable foundation, 3. the center of the coupling not being properly aligned
Has any medium solidified on the impeller or volute during operation?
