| Resumen: | This standard provides specific guidance for assessing the severity of radial vibration measured on the shafts of coupled industrial machines with fluid-film bearings in situ. It applies to coupled industrial machines with fluid-film bearings, having maximum continuous rated speeds in the range 1000 r/min to 30000 r/min and not being limited by size and power (with certain restrictions), comprising - steam turbines and generators with outputs less than or equal to 40 MW; - steam turbines and generators with outputs greater than 40 MW and speeds other than 1500 r/min, 1800 r/min, 3000 r/min or 3600 r/min (although generators seldom fall into this category); - rotary compressors; - industrial gas turbines with outputs less than or equal to 3 MW; - turbofans; - electric drives and associated gears, where relevant; - rotodynamic pumps (turbo pumps). Two criteria are provided for assessing the machine vibration when operating under steady state conditions. One criterion considers the magnitude of the observed vibration; the second considers changes in the magnitude. In addition, different criteria are provided for transient operating conditions, such as run-up and coast-down. The evaluation procedures presented in this part of ISO 7919 are based on broad-band measurements. The following are excluded from this part of ISO 7919: - steam turbines and/or generators with outputs greater than 40 MW and speeds of 1500 r/min, 1800 r/min, 3000 r/min or 3600 r/min (see ISO 20816-2); - gas turbine sets with outputs greater than 3 MW (see ISO 7919-4 and ISO 20816-2); - machine sets in hydraulic power generating and pump-storage plants (see ISO 20816-5); - rotodynamic pumps including integrated electric motors, i.e. where the impeller is mounted directly on the motor shaft or is rigidly attached to it (see ISO 10816-7); - submerged motor-pumps; - reciprocating pumps; - rotary positive displacement compressors (e. g. screw compressors); - reciprocating compressors; - wind turbines. |
