Résumé:
In mechanical engineering, especially in machine maintenance, vibration monitoring plays a
critical role in ensuring optimal performance and extending equipment lifespan. It is essential
for enhancing machine availability, enabling timely scheduling of repairs and balancing
interventions, and detecting various mechanical faults.
The centrifugal finisher pump under consideration required vibration monitoring, which
significantly improved its operational availability. Through this process, we were able to
proactively schedule maintenance activities, such as repairs and shaft balancing.
Several mechanical defects were identified in the installation, including:
Misalignment between the two motor shafts and the turbine shaft.
Bearing faults in the turbine shaft, which resulted in frequent bearing replacements.
The repeated failure of the turbine shaft bearings highlighted the need to reassess and resize the
bearings to better match the system’s operational demands.
These observed practical results will be compared with numerical analysis outcomes to validate
findings and refine the design and maintenance strategies.
