Definitions
- the present invention relates to a water lance blower according to the preamble of claim 1 and a method its operation.
- a water lance blower is known from WO-A-93/12398.
- the water jet from water lance blowers generally follows one certain predetermined path on the surface to be cleaned, also blow figure called, this path generally meandering or spiral runs and possibly obstacles, openings or other sensitive Excludes zones.
- the cleaning parameters are known from DD 239 656 A1 a water lance blower based on temperature measurements on the to control the cleaning surface.
- the blowing lance is guided over Mechanics and central drives, being in the space around the blow guides Drive and bearing elements stored in a frame construction and are arranged, which occupy a large space.
- the often big one Length of the lance and the water supply leads to great leverage and Forces, which in turn have corresponding guides, drives and frames require.
- the object of the present invention is therefore to create a drive system for a water lance blower, which is flexible even under confined spaces Space can be arranged and also free choice any blow figures and any movement speeds.
- the object of the invention is also to create a suitable method to operate such water lance blowers.
- the water lance blower according to the invention for cleaning heating systems is movable by at least one movement element, which at one end with the water lance blower and with the other end directly with the Heating system is connected.
- the drive system with displacement transducers equipped for precise determination of the position of the water lance, whereby a regulated driving style can be realized.
- the movement element at least part of a manipulator arm.
- One end of the manipulator arm is preferably attachable to the heating system so that the water lance blower in terms of maintenance and inspection is easily accessible without the Space on a work platform is unnecessarily restricted.
- the manipulator arm itself can be designed freely, in one embodiment the movement element even the manipulator arm is.
- the drive system has displacement sensors to determine the exact position of the water lance, so that now no pure control, but a regulated control along a target movement line is possible.
- the displacement transducers enable that precise control of the blow figure, so that the movement elements accordingly can be regulated.
- the drive system also allows it, certain Parts of the blow figure at a first speed and other parts of the Blow figure, for example, uncontaminated or sensitive areas; With to drive at a second speed. Basically, any Blow figures and any speed profiles programmable or through Recording can be saved on site.
- the displacement sensors can either be in the movement elements themselves be arranged as a typical displacement or angle transducer, or they can be arranged on one or more displacement transducer arms. Important is, that the exact position of the water lance with respect to a reference position, which may be specified before the start of the blowing process, can measure. Capacitive, inductive or are suitable as displacement transducers magnetic sensors, as well as digital pedometers and the like.
- the control takes place in a common control electronics, which the measured values the displacement sensor receives with the setpoints of the given Blow figure compares and controls the movement elements accordingly.
- the movement elements can for example hydraulic or pneumatic reciprocating pistons, as well as known spindle or rack and pinion drives also electric or magnetic drives or the use of a manipulator arm is possible. Depending on Space can also be an advantage when using the movement elements Levers, cables, chains, swivel joints and the like to the spatial Adapt conditions.
- One method of operating the system is to that the system is built on site and then the blow figure based on a Template or by visual observation of the water jet for the first time traversed and the associated measured values of the displacement sensors are saved become. Also a calculation of the target values for the displacement sensors for each Any blow figure is possible after the measured values of the displacement transducers have been determined for certain reference points.
- the invention allows almost any arrangement of one or more Movement elements depending on the local conditions, the Regulation of the movement element (s) by displacement sensors despite the necessary complicated coordinate transformations the exact descendant predefined blow figures with predefined speed profiles.

- Different flow guides like them can be explained in more detail with the aid of the drawing, so that at the same time cooling, protection against contamination (flushing) and Prevention of an uncontrolled gas exchange through the hatch (blocking) can be achieved.
- Flushing protection against contamination
- Prevention of an uncontrolled gas exchange through the hatch (blocking) can be achieved.
- this can be done by the Flushing medium can flow around in the manner of a jacket jet.
- Suitable measurement and control variable for the locking function of the medium is in particular the differential pressure between the interior of the heating system and Interior of the housing. If this value is kept constant, then never flow gas from the heating system into the housing and the current of barrier medium in the heating system remains constant at an acceptable level low level.
- Suitable measurement and control variable for the rinsing function (or cooling function) of the medium is in particular the temperature at one or more Measuring points in the front area of the water lance or near the Movement point. If this point is kept constant, the will vary Amount of cooling medium depending on the operating conditions, however only to the extent absolutely necessary for the rinsing function.
- Both regulations can also be used in combination, for example initially the differential pressure is kept constant, but at Switched to a temperature control when a limit temperature is exceeded becomes.

- the ropes run on the fixed bearings 9.1-9.3 via rolls or are wound up / unwound on these rolls.
- a counterweight 29 (shown in dotted lines). Own the roles Actuators 25.1-25.3 with their consoles.
- the hatch 2 is through one Junction box 30 limited.
- the outer edge of the junction box is over a housing 31 sealed with the lance 6 and forms an air flow free interior 32.
- the lance 6 with its nozzle 33 has one at the end Inlet 34.
