Application of Hydrostatic Lubrication to Vertical Water Wheel Generator Thrust Bearings [includes discussion]

This paper presents a discussion of the application of hydrostatic lubrication to pivoted pad thrust bearings during the starting period. Two systems, the externally pressurized system and the hydraulic lifting system have been used to provide an oil film between the bearing surfaces prior to starting. Current design features and practices of both systems are described. It is hoped that, as a result, the present discussion will be of service in furthering the understanding of the purpose and use of hydrostatic starting lubrication.
