Circulation Pump Isolator Bolt Looseness
High-amplitude vibrations were observed in the pump system, particularly in the horizontal direction at 1X operating frequency, indicating potential mechanical looseness. A visual inspection revealed a loose isolator connection bolt, which was tightened, resulting in decreased amplitude values and proper system operation.

The analysis interpretations and the graphs representing these interpretations are shared in the rest of the case analysis.
Comment:
• When the pump system data is examined, high-amplitude vibrations are observed, especially in the horizontal direction, at 1X operating frequency. The analysis concluded that mechanical looseness may be present.
Conclusion:
A visual inspection of the equipment revealed that one of the isolator connection bolts under the base had fallen. After strengthening the connection, the data obtained indicated that the amplitude values decreased and the system was operating properly.
