The centrifugal pump experiences excessive vibration
Thread Content
The shaft at the drive end of a multi-stage crude oil transfer centrifugal pump experiences intermittent excessive vibration; seek a solution.
Check the bearings and couplings, heart
First, the frequency spectrum of the pump vibration is measured to analyze the possible causes of the vibration. Based on these different causes, further investigations are carried out to address the issue appropriately: such as problems related to motor alignment, bearing failures, coupler issues, loose foundation bolts, or motor rotor defects.
Considering intermittent vibration, check whether there have been any changes in the process parameters
Correct the concentricity, check whether the bearing is damaged, and verify if there have been any changes in the operating parameters!
It is necessary to consider the process aspects; for example, changes in liquid level or composition can cause intermittent vibrations.
One is to check from the equipment perspective, and the other is from the process perspective. Intermittent evacuation?
