标准简介：This part of ISO 7919 establishes provisions for evaluating the severity of in-situ, broad-band shaft vibration
measured radial (i.e. transverse) to the shaft axis at, or close to, the main bearings. These are in terms of:
⎯ vibration under normal steady-state operating conditions;
⎯ vibration during other (non-steady-state) conditions when transient changes are taking place, including
run up or run down, initial loading and load changes;
⎯ changes in vibration which can occur during normal steady-state operation.
This part of ISO 7919 is applicable to land-based steam turbines and generators with power outputs greater
than 50 MW and a normal operating speed of 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min. It is also
applicable to steam turbines and/or generators which are directly coupled to a gas turbine (such as for
combined-cycle applications). In such cases, the criteria of this part of ISO 7919 apply only to the steam
turbine and the generator (including synchronizing clutches). ISO 7919-4 and ISO 10816-4 are applicable to
the evaluation of the gas turbine vibration.
The numerical values specified are not intended to serve as the only basis for judging the severity of vibration.
For large steam turbines and generators, it is also common to judge the vibration based on measurements
taken on non-rotating parts. For such vibration measurement requirements, see ISO 10816-1 and
ISO 10816-2.
