Technical Specification
Compressed air for industry and businesses that use compressed air as an energy source is generated by means of so-called compressed air generation systems. A key component of these systems is the compressor. It converts the supplied mechanical energy into a higher air pressure. It includes a complete compressed air generation system with a two-stage compressor and pressure vessel. The trainer enables the recording of compressor characteristics and representing the compression process in a p-V diagram. The air is sucked into the intake vessel through a measuring nozzle and calmed there before it is compressed in two stages. The additional pressure vessel for inter cooling is located between the first and second stage. After the second stage, the compressed air is pressed into another pressure vessel through a cooling tube. To achieve a steady state, the compressed air can be released through a blow-off valve with silencer. Safety valves and a pressure switch complete the system. Sensors measure the pressures and temperatures in both stages as well as the electric power consumption. A nozzle at the intake vessel serves to determine the intake volumetric flow rate. The measured values can be read on digital displays.


At the same time, the measured values can also be transmitted directly to a PC via USB. The data acquisition software is included.
