France - Parts of hydraulic turbines

Description

Génissiat Hydropower plant is composed of six Francis-type turbines. The runners of these hydraulic turbines are original (commissioned between 1948 and 1958), some of them are in the end of life cycle.The aim of the project is to replace at this stage one runner on an undetermined lot yet.— scope: design and construction of Francis-type runners for integration on existing turbines, onsite delivery, assembly supervision, commissioning, tests;— option: on scale model (performance warranty);— option: related works and services (disassembly existing runner, assembly of new runner).
Project perimeter:The scope of the project includes design activities, supplies and services:— hydraulic studies of the runner using CFD type numerical calculations,— hydraulic studies of the runner blades,— mechanical studies of dimensioning runners, runner crown, runner band, blade,— design activities of runner installation in the existing environment,— runner manufacturing and balancing,— delivery (onsite),— Adaptation of the runner to the existing turbine components,— runner assembly supervision,— prototype tests performance.Current equipment operating on site:G1/G3Lot 1Manufacturer SFAC/KMWThe nominal net head 64.5 mPower under Hn 66 176 kWRunner diameter 4 100 mmRunner weight 29 tRotation speed 150 rpmRotation direction clockwise.
