Finding earlier faults in critical machinery by using vibration analysis saves down time and further damage to the machine. Diagnosing 1x vibration seems to be very easy on most of the general rotating machinery. But when it comes to critical machinery like steam turbines, it requires tremendous data and accurate diagnosis for the root cause of 1x vibration. The following unsolved case study discusses intermittent and unpredictable 1x vibration in a 120 MW steam turbine in an Integrated Steel Plant.
1. Attendees will explore correlating process and vibration data for better diagnosis.
2. Attendees can know how decision making can be done for corrective action after fault finding.
3. Better usage of vibration analysis for increasing the availability.
