Akosombo GS – 1020 MW PTFE Thrust Bearing Solution

After installing high-performance turbine runners during a major overhaul, Akosombo GS had experienced increased thrust bearing operating temperatures and cavitation on its thrust bearing pads.

The Volta River Authority contracted Hydro Tech to design thrust bearing improvements: the solution featured new and modified split thrust bearing rotating rings and superior thrust pads of a higher load carrying capacity.
