Characteristic Variables of Hydraulic Turbomachines

Characteristic Variables of Hydraulic Turbomachines .

Specification Of Characteristic Variables of Hydraulic Turbomachines

• Determining characteristic variables of a centrifugal pump
• Experiments on a pump in a closed water circuit with storage tank and flow control valve to adjust the back pressure
• Experiments on turbines: closed water circuit for supplying turbines
• Pipes and fittings made of PVC
• 3-phase AC motor for pump with variable speed via frequency converter
• Non-contact speed measurement at the turbine shaft and force sensor at the brake for measuring the torque 
• Digital displays for pressures, flow rate, speed and torque
