  • the cleaning parameters are known from DD 239 656 A1 using a water lance blower of temperature measurements on the surface to be cleaned to control.
  • Two-axis controls were mainly produced placed on a frame with control axes lying at right angles to one another, in particular one horizontal and one vertical Axis, particularly easy around meandering paths to be able to control. That was the way it used to be always possible, certain meandering blow figures through pure time control or control from a minimum stop to a maximum stop of the individual final drives.
  • the object of the present invention is therefore the creation of a drive system for a water lance blower, which is flexible even under confined spaces Space can be arranged and also the free choice of any blow figures and any Permits movement speeds.
  • Object of the invention is also creating an appropriate process to operate such water lance blowers.
