Visualise: Make sure the pump shaft doesn’t move, that no components are loose, coupling is properly bolted and not loose and the motor is bolted and stable.
Touch and inspect: Verify that the motor doesn’t overheat and check periodically that there is enough lubrication as per the manufacturer’s best practice.
Listen: Verify that there are no strange or unusual noises.
Misalignment can increase vibration and lead to premature wear of the internal components. Use a straight edge (as straight as possible) to obtain coupling between the pump and the shaft. For optimum alignment, we recommend using a laser alignment tool.
Here are four reasons why you should carry out a vibration measurement analysis of your slurry pumps:
These measurements must be taken every three months until you have reached a critical vibration level. Remember to take measurements after the slurry pump has been running for at least an hour. If you measure it when it’s empty, there will be an imbalance (which is normal) and your analysis results will not be optimal.
It is crucial to never run a pump empty to avoid overheating the bearings, cavitation and premature wear of the impeller.
Make sure greasing points maintenance procedures are followed in order to avoid premature wear or breakdown.
