Vibration in Suction piping
Vibration in Suction piping
(OP)
Hi, My question is about the vibration that is experienced in the suction piping of a single stage centrifugal pump in a chilled water application for human comfort.
The piping arrangement is like this; suction has positive pressure with a air separator and a strainer installed just before the suction point, whenever the pump is in operation, the whole piping from the strainer to the pump suction point vibrates. Can anybody advice me on the causes.
Thanks..

What is the velocity through the line? (or give line size and gpm)
Is the strainer sized correctly.
Did you take the strainer out and test without screen to see if that was the cause?
What type of strainer?
I doubt that I will have answer, but these are questions that would help us help you.

Therefore I say check your suction source.

I'd check alignment, and possibly that the impeller was properly balanced at the factory.
