About Experiments With A Centrifugal Pump

EXPERIMENTS WITH A CENTRIFUGAL PUMP

Centrifugal pumps are turbomachines which are used to transport fluids. The rotation of the pump impeller generates centrifugal forces. These forces are used to deliver the water.

The experimental unit provides the basic experiments to get to know the operating behaviour and the important characteristic variables of centrifugal pumps.

features a closed water circuit with water tank and a centrifugal pump with variable speed via frequency converter. The pump

housing is transparent. This enables to observe the pump impeller in operation and the occurrence of cavitation. Valves in the inlet and outlet of the pump allow the setting of different pressure conditions.

The experimental unit is fitted with sensors for pressure, temperature and flow rate. The microprocessor-based measuring technique is well protected in the housing. All the advantages of software-supported experiments and software and 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.
