Tiivistelmä
This thesis work was done in cooperation with Hi-Tekno Engineering and consulting office. The purpose of this thesis was to demonstrate the importance of vibration measurements in modern day production systems. The aim was to explain how vibration measurements are performed in the field and what kind of machinery diagnosis can be achieved.
Effective maintenance services in the production systems of today are vital for any company as to the profitability figures. Vibration measurements give the user a clear picture of the machines condition, by this is easier to plan the maintenance schedule, focusing the resources only on those machines that have signs of failures.
A vibration analysis is about the art of looking for changes in the vibration pattern, and then relating those changes back to the machines mechanical design. The level of vibration and the pattern of the vibration tell us something about the internal condition of the rotating component. The vibration pattern can tell us if the machine is out of balance or out of alignment. Also faults with the rolling elements and coupling problems can be detected.
The practical work in this project was conducted in Karkkila at the heating system plant of the municipality. I measured the vibration levels for the flue gas fan. The flue gas fan removes the gases generated in the combustion boilers, after which they have passed through a filter and are directed back into the atmosphere. The outcome demonstrated that there was a bearing problem in the flue gas fan and it was starting to develop.
