Francis Turbine Test Rig

The Arban Industries GL-HM202B Francis Turbine Test Rig is a comprehensive hydraulic machinery demonstration system designed for investigating performance characteristics of reaction-type turbines used in hydroelectric power generation. This equipment features a scaled Francis turbine runner with adjustable guide vanes, precision flow measurement instrumentation, torque and speed measurement systems, and variable load application mechanism. The rig enables experimental determination of turbine efficiency curves, investigation of specific speed relationships, and study of cavitation phenomena under various operating conditions. It facilitates comprehensive performance testing including measurement of hydraulic efficiency, mechanical efficiency, and overall efficiency across different head and discharge combinations. The system includes pressure and flow measurement instrumentation, dynamometer for power output determination, and data acquisition capabilities. This educational and research platform provides essential understanding of turbomachinery principles, demonstrating the energy conversion process in hydraulic turbines while enabling validation of theoretical performance predictions.
