Radial fans are used to transport gases with non- excessive pressure differences. The medium is drawn axially to the drive shaft of the radial fan and is deflected by 90° by the rotation of the rotor and discharged radially.
Tesca Radial Fan test Apparatus the experimental unit provides the basic experiments to get to know the operating behavior and the most important characteristic variables of radial fans. features a radial fan with variable speed via a frequency converter, an intake pipe, and a delivery pipe. The transparent intake pipe is fitted with guide plates for flow guidance and with a flow straightener to calm the air. This enables precise measurements even with the heavily reduced operation.
The airflow is adjusted by a throttle valve at the end of the delivery pipe.
To demonstrate the effect of different blade shapes two rotors are included in the scope of delivery: one rotor with forwarding curved blades and one with backward curved blades. The rotors are easily interchangeable.
The experimental unit is fitted with sensors for pressure and temperature. The flow rate is determined via differential pressure measurement on the intake nozzle.
The microprocessor-based measuring technique is well protected in the housing. All the advantages of software-supported experiments and evaluation are offered by the 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.
