Thrust-Bearing Power Loss

Thrust-Bearing Power Loss The power consumed by various thrust bearing types is an important consideration in any system. Power losses must be accurately predicted so that turbine efficiency can be computed and the oil supply system properly designed. 

Figure 10-123 shows a typical power consumption in thrust bearings as a function of unit speed. Tne total power loss is usually about 0.8-10 percent of the total rate power of the unit. New vector lube bearings reduce the horsepower loss by as much as 30 percent. In large vertical pumps, thrust bearings take not only the load caused by...
