I have a similar problem with a vertical pump using a corkscrew type impeller. I get very high vibration levels (45mm/s) when water is pumped through the system. The main component of the vibration is at 1X the motor speed. Can someone explain how the 1X component is produced. I assume it is...
Thanks for the response. However, I am looking for a method to do a 2 plane balance without phase measurements. I read a reference to it in Victor Wowk's book "Machinery Vibration, Balancing". It implies a method similar to the 4-run method but using 7 runs. Has anyone seen this...
Dear All,
Does anyone know where I can get details on 2 plane balancing using the 4 run method? I am told it can be done and converges quite well.

Siva.
Greetings All,
I am a young engineer starting out in the noise & vibration consulting industry. I have already been on a few machinery vibration investigations and have written a few reports.
However, I feel my approach to problem solving has been a bit hap hazard, and am therefore looking...
