Add to wish list

The exercise books are tailored to the device sets. These device sets build on the contents and knowledge from the "On/off hydraulics – Manual operation (BIBB, A-H)" and "Mobile hydraulics – Throttle control" learning topics.

The described exercises and tasks provide basic information and methods. The setup is structured in a uniform manner and provides the step-by-step description for completion of the individual exercises.

The following exercises are included:

No. Exercise
01 Primary pressure limitation
02 Actuator flow
03 Load pressure compensation
04 Pressure losses in p line
05 Hydraulic pilot control
06 External force
07 Outlet pressure limitation
08 LS pressure limitation
09 Parallel operation with sufficient delivery volume
10 Parallel operation with too little delivery volume
11 Load change

With the help of logically structured, practice-related exercises, the trainee shall learn the following:

  • understand physical laws of hydraulics such as pressure difference, opening cross-section and flow,
  • get to know and use specific graphical symbols,
  • understand the function of the load-sensing control,
  • get to know components such as 4/3 directional control valve, load holding valve, primary and secondary valve, pressure compensator, hydraulic pilot control,
  • understand the connection between control and velocity,
  • get to know the function of the load-sensing control in parallel operation,
  • work out the function and application of the hydraulic pilot control,
  • determine characteristic values and derive characteristic curves from them, if required.
