AHM282 Experiments With An Axial Fan Vocational Training Equipment Heat Transfer Training Equipment

1. Description
2. Axial fans are used to transport gases. The medium to be transported is drawn in axially to the drive shaft of the axial fan by the rotation of the rotor. The medium flows through the rotor and is discharged axially behind the rotor.
3. The experimental unit provides the basic experiments to get to know the operating behaviour and the important characteristic variables of axial fans.
4. HM 282 features an axial fan with variable speed via an integrated controller, an intake pipe and a delivery pipe. The transparent intake and delivery pipes are fitted with guide plates for flow guidance. A flow straightener in the intake pipe serves to calm the air. This enables precise measurements even with heavily reduced operation. The air flow is adjusted by a throttle valve at the end of the delivery pipe.
5. The experimental unit is fitted with sensors for pressure and temperature. The flow rate is determinated via differential pressure measurement on the intake nozzle. The microprocessor-based measuring technique is well protected in the housing. The measured values are transmitted directly to a PC via USB where they can be analysed using the software included.
6. All the advantages of software-supported experiments with operation and evaluation are offered by the software and the microprocessor.
