Hydraulic reaction turbines with radial inflow runners have the advantage of high efficiency power generation over a wide range of mass flow with a predictable and reliable hydraulic performance. Multistage reaction turbines are applied to operations where there are large differential pressures. These machines are generally of compact design with the stage runners and the generator rotor mounted on a single shaft. The disadvantage of multistage hydraulic turbines is the high level of axial thrust force generated by the high differential pressure across the turbine, resulting in heavy loads on the turbine bearings. To eliminate this axial thrust, a special Thrust Equalizing Mechanism for hydraulic turbines is presented, which reduces the load on the bearings to a negligible level. The advantage of this new design is to significantly improve the key features of the turbine, namely efficiency, reliability and operational costs.
