This part of ISO 7919 gives guidelines for applying evaluation criteria for shaft vibration measured at, or close to, the bearings of machines or machine sets in hydraulic power generating and pumping plants under normal operating conditions. These guidelines are presented in terms of both steady-state running vibration and any amplitude changes that can occur in these steady vibration values. NOTE 1 The numerical values specified are not intended to serve as the only basis for vibration evaluation since, in general, the vibratory condition of a machine is assessed by consideration of both the shaft vibration and the associated structural vibration (see ISO 7919-1 and ISO 10816-1). This part of ISO 7919 is applicable to machines or machine sets in hydraulic power generating and pumping plants where the hydraulic machines have speeds from 60 r/min to 1 800 r/min, shell- or shoe-type sleeve bearings, and main engine power of at least 1 MW. The position of the shaft line can be vertical, horizontal or at an arbitrary angle between these two directions. Machine sets covered by this part of ISO 7919 include a combination of -- hydraulic turbines and generators, -- pumps and electrical machines operating as motors, -- pump-turbines and motor-generators, and -- hydraulic turbines, pumps and motor-generators (classic pump-storage machine sets), including auxiliary equipment (e.g. starting turbines or exciters lying in the shaft line). This part of ISO 7919 is also applicable to turbines or pumps connected to generators or electrical motors via gears and/or radially flexible couplings. NOTE 2 Electrical machines with speeds between 1 000 r/min and 1 800 r/min are evaluated according to the criteria specified in ISO 7919-3.
