Radial forces are important parameters for the design of pump turbines and Francis turbines. Until now the forces were measured with special measuring arrangements. Establishing these arrangements and measuring itself was very time consuming. As the time between start of the project and going into service of the machines should most of the time be as short as possible, these tests were often canceled. Consequently important machine parameters were not available for the design of the rotating parts of the turbine. To overcome this discrepancy, ASTRÖ developed a new measuring system, which allows the change from normal testing to radial force measurement without any delay. The following paper shows details of the new solution as well as first measuring results.
