The training packages for mobile hydraulics take components which often appear in vehicles as highly integrated, functional modules and present them as separate, individual elements with unique symbols and clear terminal identification codes. The teaching principle behind this is guiding students step-by-step from a simple component to a complex, complete picture with practical demonstrations. Many vehicles and applications use constant or variable displacement pumps. In these training rigs, the energy usage of different systems, also when under load, is compared and assessed. Systems with multiple consuming devices are set up, connected in parallel, tandem, and series, and examined in terms of characteristics, such as priority, flow rate distribution, and pressure dependency.
