The base unit enables basic experiments on a centrifugal pump.
The closed water circuit of features a water tank and a centrifugal pump with variable speed via a frequency converter. The turbine to be investigated is placed on the tank cover and is connected to the base unit via a hose. The flow rate hence the pressure applied to the turbine is adjusted by pump speed. The head and the pressure upstream of the turbine can be kept constant by a pressure control. A damping plate inside the tank ensures a low air entry into the circulating water. Basic pump experiments can be performed using the throttle valve included. The throttle valve is placed upon the tank cover instead of the turbine.
The base unit is fitted with sensors for pressure and flow rate. The microprocessor-based measuring technique is well protected in the housing. All the advantages of softwaresupported experiments and software the microprocessor. The connection to a PC is made by USB. The well-structured instructional material sets out the fundamentals and provides a
step-by-step guide through the experiments.
