Sobradinho modernization update
Testing of movement, pressure, and tightness in Sobradinho
The team from ANDRITZ Hydropower Brazil continues to carry out the modernization work on the generating units of the Sobradinho Hydroelectric Plant. The testing of movement, pressure, and tightness of the first refurbished generating unit began between the end of February and the beginning of March 2024.
The rotor shown in the images was refurbished by the ANDRITZ team, encompassing complete recovery by removing cavitations, pores, and cracks, as well as modifying the sealing system between the rotor and Kaplan blades.
In the images below, you can see the pressure and sealing tests. This procedure involved on-site supervision, product engineering, and six assemblers. Check it out!
