Bibliography

Provides guidelines for application of bearing housing vibration evaluation criteria measured under normal operation conditions at the bearings, bearing pedestals or housings of the main machine sets in hydraulic power generating and pumping plants, given in terms of both steady-state running vibration and any amplitude changes occurring in these steady values. Applicable to machine sets in hydraulic power generating and pumping plants where the hydraulic machines have have speeds from 60 r/minute to 1800 r/minute, shell or shoe type sleeve bearings and a main engine power of 1 MW and more.
