Effective Procedure for Turbomachinery Field Balance
Abstract
When unbalance induced vibrations exceed allowable limits, a more accurate system balance is
required. If performed at site on assembled machines, it is commonly called field balance.
Key point of the activity is the determination of the unbalance amount and position, to be
added or removed, in order to minimize the trial and error attempts: it can be challenging due
to the quality of available data and due to a lot of variable factors to be considered, both during
analysis and activity execution.
The present case study shows how a field balance, performed on a gas turbine compressor
train, composed by five rotating equipment, can be effective and resolutive at first attempt.
