Regarding pipeline vibration issues
Thread Content
We have a backup pump that is greatly affected by the vibrations of the operating pump; the vibrations transmitted through the pipelines are quite severe. Does anyone have any solutions to this problem? :)
The vibration transmitted through your pipeline is causing the standby pump to vibrate significantly – this is a rare occurrence. Does this mean that the pump in operation itself has high vibration levels? This problem should be solved first. If we consider your question itself, the simplest solution is to reinforce the support for the pipelines by using columns with high rigidity to firmly secure them.
How about adding a expansion joint at each of the inlet and outlet of the two pumps? The main thing is to find out what is causing the vibration in your pumps – could there be an issue with their installation?
Is it a centrifugal pump or a reciprocating pump? In the case of a centrifugal pump, such vibration is quite rare. For reciprocating pumps, it is necessary to consider installing buffer tanks at the pump’s inlet and outlet. Merely adding supports for the pipelines is not enough to solve the problem; the system will soon become damaged due to vibration.
Possible cause analysis: 1) There is a problem with the main pump; changing the process operations might reduce pipeline vibration； 2) Pipeline support needs to be strengthened ； 3) If nothing else works, you can try adding some soft links; give it some thought.
It seems there’s no good solution for now; it’s better to check the pipelines – it’s likely that the design in some part is inadequate
1. Is there a problem with the pump?； 2. Is the pipeline not properly secured? ； 3. Is the pump base not properly secured?
This situation is rare; the backup pump experiences high vibration, so it is necessary to check whether the vibration of the operating pump is within the specified range It would be best to find out the reason why the pump is not working Either install a spring support hanger on the outlet pipeline of your backup pump to secure the pipeline.
