The fan vibration is highly fluctuating
Thread Content
It’s a turbine unit equipped with a fan; the shaft vibration of the fan fluctuates significantly as the air flow is increased or decreased. Experts, what could be the possible reasons for this?
1. Belt 2. Incorrect center alignment. Friends are welcome to add more details
The connection method for steam turbine units is basically of the gearbox type; belts cannot handle such high loads under operating conditions!
Maybe the gap between the tiles is too large; is it just an ordinary centrifugal blower? What kind of fluctuations are there? Are there any changes in oil temperature and pressure?

This isn’t my reply to myself; it’s all aimed at addressing the issues. Please understand
Large-scale blast furnace air supply units, steam turbines driving axial flow fans
It turned out that the tiles on both the front and back sides were tiltable; later, the tiles on the exhaust side were changed to elliptical ones
