Hydro turbine thrust bearing
Hydro turbine thrust bearing
(OP)
80MW kaplan hydro turbine commisioned in 1969, we are experiencing serious thrust bearing overheating for the last three years. The bearing is a self pumping external heat exchangers, we introduced circulating pump to ease the problem but it persists - need your help.

what changed 3 years ago?
Possibly an overhaul, change in thrust position, a possible maintenance event that went unrecorded that could have damaged the bearing, etc??
