Radial compressors are used to compress gases. The experimental unit provides the basic experiments to get to know the operating behaviour and the important characteristic variables of radial compressors. A protective plate placed in front of the inlet of the intake pipe prevents larger objects from being sucked in or the clogging of the intake opening. The medium is sucked in axially to the drive shaft by the rotation of the impeller and flows through the impeller rotating at high speed. By means of centrifugal force, the medium is accelerated towards the outer edge and is compressed in this manner. The air flow is adjusted by a throttle valve at the end of the delivery pipe. The microprocessor-based measuring technique is well protected in the housing. The experimental unit is fitted with sensors for pressure, temperature and speed. The flow rate is determinated via differential pressure measurement on the intake nozzle.

The axially discharged water from the turbine impeller can be observed. The number of active nozzles can be adjusted by valves. The eddy current brake generates a defined load. The experimental unit is placed upon the base unit. The two units together provide the basic experiments to get to know the operating behaviour and the most important characteristic variables of action turbines. Action turbines operate according to the principle of equal pressure. The water jets are deflected in the turbine impeller and put it in motion. The eddy current brake is specially developed by.The torque delivered by the turbine is determined via an electronic force sensor. The speed is measured with an optical speed sensor. The static pressures at the inlet and at the outlet of the impeller are equal. The water jets are discharged with high velocity from four nozzles of the distributor.
