VIBRATION MEASUREMENT OF CENTRIFUGAL PUMP AND ENGINE ASSEBLY

Customer:M/s Weir Minerals India Pvt.Ltd. Bangalore.

Equipment:Centrifugal Pump with Engine Assembly through Flexible Coupling

Initially the vibration measurement was carried out on the engine in decoupled condition to know the existing vibrations, when it is supported on jacks. The abnormal vibrations of the order of 69.3 mm/sec was noticed in this condition and the detailed analysis was carried out and the analysis results depicts, the problem was due to 1.2mm run out in the engine stub shaft.

This engine stub shaft run out was resulting into higher unbalance induced vibration. Finally the stub shaft run out problem was corrected. The existing vibration level came down to 20mm/sec. Further analysis was pointing out to lesser structural rigidity of the based frame. The structural rigidity of the base frame was modified by the OEM to increase the stiffness and rigidity of the structure. Finally, the vibration level came down to less than 5mm/sec.
