weights and spare weights for the balancing purpose. In this case we recommend
that you use them.
It is especially related to heavy electrical machines, for example, turbine electric
generators.
However in most cases a user can produce the correction weight himself depending
on the design of the balancing plane. If the machine doesn’t have a balancing plane
then one can use some available parts of the rotor.
For example, half couplings can be used as balancing planes. As for pumps,
exhausters and similar machines the correction weights can be installed on blades
and turbine discs. In some cases one can use so called technological planes that are
mounted on the rotors for the balancing purpose. They are removed and a required
correction weight is mounted (e.g. welded) on the rotor. Further the technological
plane is used to perform the balancing of a similar machine. The Figure 9 and Figure
10 show the most common correction weights and installation methods.
