Energy is converted by turbomachines, including pumps and turbines. Pumps transform mechanical energy into flow energy, while turbines transform flow energy into mechanical energy. An investigation into a centrifugal pump and Pelton wheel turbine can be conducted using this test equipment. Pelton turbine experiments are another option. A tank, a typical centrifugal pump with variable speed, and a flow control valve to regulate the back pressure make up the closed water circuit. A contact-free inductive displacement sensor located on the motor shaft measures the speed. The drive motor is positioned on swivel bearings and has a force sensor to gauge drive torque in order to calculate drive power. Measurements are made of the pressures at the pump’s input and exit. The flow rate is measured by means of an electromagnetic flow meter (optional). The measured values are displayed digitally.
