SR292 Experiments With A Radial CompressorVocational Training Equipment Hydrodynamics Laboratory
1. Description Radial compressors are used to compress gases. The medium is drawn in axially to the drive shaft by the rotation of the rotor and flows through the rotor rotating at high speed. By means of centrifugal force, the medium is accelerated towards the outer edge and is compressed in this manner. The experimental unit provides the basic experiments to get to know the operating behaviour and the important characteristic variables of radial compressors. features a two-stage radial compressor with variable speed via a frequency converter, an intake pipe and a delivery pipe. The intake and delivery pipes are transparent. A protective plate placed in front of the inlet of the intake pipe prevents larger objects from being drawn in or the clogging of the intake opening. The air flow is adjusted by a throttle valve at the end of the delivery pipe. 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. 2.
