Definitions

  • the present invention relates to a water lance blower according to the preamble of the claim 1 and a procedure for its operation.
  • Such one Water lance blowers are known from WO-A-93/12398.
  • the water jet from water lance blowers generally follows a certain given one Path on the surface to be cleaned, also called blow figure, this path generally meandering or spiral and possibly obstacles, Cut out openings or other sensitive zones.
  • 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.
  • the water lance blower according to the invention for cleaning heating systems is by at least a moving element that is movable at one end with the water lance blower and with the other end is directly connected to the heating system. additionally is the drive system with displacement sensors for precise Determination of the position of the water lance equipped, whereby a regulated driving style is realized leaves.
  • One end of the manipulator arm is on the Heat system preferably attachable so that the water lance blower in terms of maintenance and inspection is easily accessible without the space of a work platform is unnecessarily restricted.
  • the manipulator arm itself can be designed freely, in one embodiment the movement element itself is the manipulator arm.
  • the arrangement of the ends of one or more each Movement elements in a plane that is perpendicular to a vertical plane through the point of movement the water lance runs, allows this Movement point far forward into the hatch or relocate the heating system, which means larger ones Swiveling ranges and more favorable leverage ratios result in the drive system.
  • the drive system Position transducer for the exact determination of the position the water lance, so that now no pure Control, but a regulated control along a target movement line is possible.
  • the displacement sensors allow precise control of the blow figure, so that the movement elements regulated accordingly can be.
  • the drive system also allows certain parts of the blow figure at a first speed and other parts of the blow figure, for example non-contaminated or sensitive areas; to drive at a second speed. in principle are any blow figures and any speed profiles programmable or by recording Can be saved on site.
  • the transducers can either be in the Movement elements themselves can be arranged as typical Displacement or angle sensors, or they can be on arranged one or more transducer arms his. It is important that they know the exact position of the Water lance with respect to a reference position, the if necessary, set before the start of the blowing process will be able to measure. Suitable as a displacement sensor capacitive, inductive or magnetic sensors, as well as digital pedometers and the like.
  • the control takes place in a common Control electronics that measure the measured values of the displacement transducers receives, with the target values of the given blow figure compares and the movement elements accordingly controls. This way, even at any Arrangement of the movement elements in the room Blow figures regarding route and speed can be repeated exactly.
  • the moving elements Levers, cables, chains, swivel joints and the like may also be beneficial to use the moving elements Levers, cables, chains, swivel joints and the like to adapt to the spatial conditions.
