Centrifugal pump in turbine mode for small hydropower
Original language description
In order to minimize investment costs when setting up small hydropower plants, pumps in reverse turbine mode are used in some cases. However, small pump units in turbine mode show decrease of overall efficiency compared to pump efficiency. The article describes innovative design changes, which reduce this negative effect. The proposed changes were verified in a hydraulic testing circuit with the following results: modifications of the existing pump design showed an increase in the efficiency by several percent, significantly increased power output and shaft torque. The best results were achieved with a new turbine runner geometry: efficiency increased by 12,5%, torque by 48% and power output by nearly 29%.
