Description

Die Erfindung bezieht sich auf ein Verfahren zum Betreiben einer Anlage zum Wasserstrahlschneiden mit einer mehrere Tauchkolben aufweisenden, an einen Wasserbehälter angeschlossenen Hochdruckpumpe und mit einer an die Hochdruckpumpe angeschlossenen Hochdruckleitung, die über ein Schneidkopfventil an einen Schneidkopf angeschlossen ist, wobei für den Schneidvorgang die Hochdruckpumpe angetrieben und das Schneidkopfventil geöffnet wird, sowie auf eine hierfür geeignete Anlage zum Wasserstrahlschneiden.The invention relates to a method for operating a system for water jet cutting with a plurality of plunger having connected to a water tank high pressure pump and connected to the high pressure pump high pressure line which is connected via a cutting head valve to a cutting head, driven for the cutting process, the high-pressure pump and the cutting head valve is opened, and on a suitable facility for water jet cutting.

Aufgrund der für das Wasserstrahlschneiden erforderlichen hohen Drücke und vergleichsweise hohen Fördermengen werden für Wasserstrahlschneidanlagen häufig Hochdruckpumpen mit Tauchkolben eingesetzt, wobei mit der Anordnung von drei Tauchkolben die Druckschwankungen auf ein für das Wasserstrahlschneiden zulässiges Maß verringert werden können, sodass Druckspeicher zum Ausgleich solcher Druckschwankungen entfallen können. Die Tauchkolbenpumpen werden üblicherweise durch Drehstrommotoren angetrieben, die über einen Frequenzumrichter angesteuert werden, der die für die jeweils gewünschte Fördermenge erforderliche Drehzahl vorgibt. Das von der Hochdruckpumpe aus einem Wasserbehälter angesaugte Wasser wird demnach mit dem eingestellten Druck, je nach den Schneidbedingungen beispielsweise zwischen 500 und 4000 bar, durch eine Hochdruckleitung dem Schneidkopf zugeführt, wo es durch eine Reinwasserdüse mit einer Geschwindigkeit bis zu 800 m/s (bei einem Förderdruck von 4000 bar) austritt, bevor dem Wasserstrahl gegebenenfalls Abrasive zugeführt werden. Zum Beenden des Schneidvorgangs wird ein der Reinwasserdüse vorgeschaltetes Schneidkopfventil geschlossen und der Drehstrommotor auf eine niedrige Drehzahl heruntergefahren, um die Hochdruckpumpe nicht für einen neuerlichen Schneidvorgang aus dem Stillstand hochfahren zu müssen. Die nach dem Sperren des Schneidkopfventils von der Hochdruckpumpe geförderte Wassermenge wird über eine Rücklaufleitung in den Wasserbehälter rückgeführt, die mit dem Schließen des Schneidkopfventils durch ein Rücklaufventil freigegeben wird. Für einen neuen Schneidvorgang ist folglich das Schneidkopfventil zu öffnen, das Rücklaufventil zu schließen und die Hochdruckpumpe auf die erforderliche Betriebsdrehzahl zu beschleunigen, sodass sich innerhalb der an den Schneidkopf angeschlossenen Hochdruckleitung der erforderliche Betriebsdruck erst allmählich mit der Folge aufbaut, dass sich während des Schnittbeginns aufgrund des zeitlichen Anstiegs der Wasseraustrittsgeschwindigkeit aus der Reinwasserdüse das Schnittbild ändert, was sich insbesondere bei Anstichen, also bei Schneidvorgängen, die nicht von einem Werkstückrand ausgehen, sondern innerhalb einer Werkstückfläche beginnen, nachteilig auswirkt.Due to the high pressures and comparatively high flow rates required for water jet cutting, high pressure pumps with plunger are often used for water jet cutting systems, with the arrangement of three plungers, the pressure fluctuations can be reduced to an allowable for water jet cutting, so that pressure accumulator can be omitted to compensate for such pressure fluctuations. The plunger pumps are usually driven by three-phase motors, which are controlled by a frequency converter, which specifies the required speed for each desired flow rate. The sucked by the high-pressure pump from a water tank water is therefore supplied with the set pressure, depending on the cutting conditions, for example, between 500 and 4000 bar, through a high pressure line to the cutting head, where it through a pure water nozzle at a speed up to 800 m / s (at a feed pressure of 4000 bar) emerges before the water jet optionally abrasives are supplied. To end the cutting process, a cutting head valve upstream of the pure water nozzle is closed and the three-phase motor is shut down to a low speed so as not to stop the high-pressure pump from being stopped again having to drive up. The amount of water delivered by the high-pressure pump after the cutting head valve has been blocked is returned via a return line into the water tank, which is released by closing the cutting head valve by a return valve. For a new cutting operation, therefore, the cutting head valve is open, to close the return valve and to accelerate the high pressure pump to the required operating speed, so that within the high pressure line connected to the cutting head, the required operating pressure only gradually builds up with the result that during the cut start due the temporal increase of the water outlet velocity from the pure water nozzle changes the sectional image, which has a disadvantageous effect, in particular in case of piercing, that is to say in cutting processes which do not start from a workpiece edge but start within a workpiece surface.

Der Erfindung liegt somit die Aufgabe zugrunde, Anlagen zum Wasserstrahlschneiden mit Tauchkolbenpumpen so betreiben zu können, dass bei einem neuerlichen Schneidvorgang ein ausreichender Wasserdruck zur Verfügung steht, um von Beginn an ein einheitliches Schnittbild sicherstellen zu können, ohne einen Druckspeicher einsetzen zu müssen.The invention is therefore based on the object to be able to operate plants for water jet cutting with plunger pumps so that in a recent cutting process, a sufficient water pressure is available to ensure a uniform cross-sectional view from the beginning, without having to use a pressure accumulator.

Ausgehend von einem Verfahren der eingangs geschilderten löst die Erfindung die gestellte Aufgabe dadurch, dass am Ende des Schneidvorgangs die Hochdruckpumpe während des Schließens des Schneidkopfventils unter Aufrechterhaltung des Drucks in der Hochdruckleitung stillgesetzt und am Beginn des Schneidvorgangs während des Öffnens des Schneidkopfventils wieder in Betrieb genommen wird.Starting from a method of the above, the invention solves the problem set by the fact that at the end of the cutting process, the high-pressure pump is stopped during the closing of the cutting head valve while maintaining the pressure in the high-pressure line and put back into operation at the beginning of the cutting process during the opening of the cutting head valve ,

Da zufolge dieser Maßnahmen der Druck in der Hochdruckleitung beim Sperren des Schneidkopfventils zum Beenden des Schneidvorgangs nicht abgebaut wird, steht dieser Druck für den Neustart eines Schneidvorgangs zur Verfügung, sodass unmittelbar nach dem Öffnen des Schneidkopfventils der Schnitt mit dem Betriebsdruck durchgeführt werden kann. Voraussetzung ist, dass die Hochdruckpumpe innerhalb der Öffnungszeit für das Schneidkopfventil auf die für den jeweiligen Betriebsdruck in der Hochdruckleitung erforderliche Drehzahl beschleunigt bzw. innerhalb der Schließzeit dieses Ventils stillgesetzt wird. Es bedarf daher keiner Rücklaufleitung, um das sonst während der Schneidpause geförderte Wasser in den Wasserbehälter zurückzuleiten.Since, according to these measures, the pressure in the high pressure line is not released when the cutting head valve is stopped to stop the cutting operation, this pressure is available for restarting a cutting operation, so that the cut can be made immediately after opening the cutting head valve with the operating pressure. The condition is that the high pressure pump within the opening time for the cutting head valve on the speed required for the respective operating pressure in the high-pressure line is accelerated or shut down within the closing time of this valve. It therefore requires no return line to return the otherwise subsidized during the cutting break water in the water tank.

Wird für einen anschließenden Schneidvorgang ein geringerer Betriebsdruck in der Hochdruckleitung benötigt, wie dies üblicherweise der Fall ist, wenn ein Anstich vorzunehmen ist, so muss vor dem Öffnen des Schneidkopfventils der Druck in der Hochdruckleitung entsprechend abgesenkt werden, damit der Schneidvorgang beim Öffnen des Schneidkopfventils mit dem verminderten Betriebsdruck durchgeführt werden kann.If a lower operating pressure in the high-pressure line is required for a subsequent cutting operation, as is usually the case when a puncture is to be made, the pressure in the high-pressure line must be lowered accordingly before opening the cutting-head valve, so that the cutting process when opening the cutting-head valve the reduced operating pressure can be performed.

Herkömmliche Antriebe der Tauchkolbenpumpen mit Hilfe von Drehstrommotoren, die über Frequenzumrichter entsprechend der geforderten Drehzahl angesteuert werden, sind im Allgemeinen nicht in der Lage, die Tauchkolbenpumpe innerhalb der kurzen Öffnungs- und Schließzeiten der Schneidkopfventile auf die Solldrehzahl zu beschleunigen bzw. von der Solldrehzahl zum Stillstand abzubremsen. Aus diesem Grund wird bei Anlagen zum Wasserstrahlschneiden, die für das erfindungsgemäße Verfahren geeignet sind, vorgeschlagen, dass der Antrieb der Hochdruckpumpe einen in Abhängigkeit von der Betätigung des Schneidkopfventils schaltbaren Servomotor mit einem Servoumrichter umfasst und dass zur Ansteuerung des Servoumrichters ein einerseits an einen Sollwertgeber und anderseits an einen Istwertgeber für den Druck in der Hochdruckleitung angeschlossener Regler vorgesehen ist. Mit Hilfe solcher Servoantriebe lassen sich die erforderlichen Beschleunigungen innerhalb von Millisekunden erreichen, sodass der jeweils vorgegebene Wasserdruck beim Öffnen des Schneidkopfventils schlagartig zur Verfügung steht. Da die Ansteuerung des Servoumrichters in Abhängigkeit von der Soll-Istwertdifferenz des Drucks in der Hochdruckleitung vorgenommen wird, spielen den Strömungswiderstand beeinflussende Änderungen im Bereich der Reinwasserdüse keine Rolle, weil durch diese Ansteuerung des Servoumrichters beispielsweise Verschleißerscheinungen an der Reinwasserdüse selbständig berücksichtigt werden.Conventional drives of the plunger pumps by means of three-phase motors, which are driven via frequency converter according to the required speed, are generally unable to accelerate the plunger pump within the short opening and closing times of the cutting head valves to the target speed or from the target speed to a standstill decelerate. For this reason, in plants for water jet cutting, which are suitable for the inventive method, it is proposed that the drive of the high-pressure pump comprises a switchable depending on the operation of the cutting head valve servomotor with a servo and that for controlling the servo on the one hand to a setpoint generator and on the other hand is provided to an actual value for the pressure in the high pressure line connected regulator. With the help of such servo drives, the required accelerations can be achieved within milliseconds, so that the respective predetermined water pressure is abruptly available when opening the cutting head valve. Since the control of the servo is made in dependence on the desired-actual value of the pressure in the high-pressure line, the flow resistance influencing changes in the range of pure water nozzle play no role, because by this control of the servo, for example, wear on the pure water nozzle are considered independently.

Um im Bedarfsfall den Druck in der Hochdruckleitung während einer Schneidpause im Hinblick auf die Druckanforderungen eines anschließenden Schneidvorgangs absenken zu können, kann die Hochdruckleitung über ein einstellbares Druckminderungsventil an eine Rücklaufleitung angeschlossen werden, das vorzugsweise auch zum Absperren der Rücklaufleitung dient, wenn das Druckminderungsventil nicht benötigt wird.In order to lower the pressure in the high-pressure line during a cutting break in view of the pressure requirements of a subsequent cutting operation if necessary, the high pressure line can be connected via an adjustable pressure reducing valve to a return line, which preferably also serves to shut off the return line, if the pressure reducing valve is not needed becomes.

Anhand der Zeichnung, die eine Anlage zum Wasserstrahlschneiden in einem schematischen Blockschaltbild zeigt, wird das erfindungsgemäße Verfahren näher erläutert.With reference to the drawing, which shows a plant for water jet cutting in a schematic block diagram, the inventive method is explained in detail.

Die Anlage zum Wasserstrahlschneiden weist eine Hochdruckpumpe 1 mit drei Tauchkolben 2 auf, die über eine Kurbelwelle 3 von einem Servomotor 4 angetrieben werden. Das zum Schneiden eines Werkstücks benötigte Wasser wird aus einem Wasserbehälter 5 über eine an die Hochdruckpumpe 1 angeschlossene Saugleitung 6 entnommen und durch eine druckseitig an die Hochdruckpumpe 1 angeschlossene Hochdruckleitung 7 einem Schneidkopf 8 zugefördert. Dieser Schneidkopf 8 umfasst eine Reinwasserdüse 9 zur Erzeugung eines Wasserstrahls zum Schneiden des Werkstücks. Dem aus der Reinwasserdüse 9 austretenden Wasserstrahl können im Bedarfsfall Abrasive zugemischt werden, um die Schneidleistung zu erhöhen, wie dies durch den Pfeil 10 angedeutet ist. Der Reinwasserdüse 9 ist ein Schneidkopfventil 11 vorgeschaltet, über dessen Stelltrieb 12 der Schneidkopf 8 ein- und ausgeschaltet werden kann.The plant for water jet cutting has a high-pressure pump 1 with three plunger 2, which are driven by a servomotor 4 via a crankshaft 3. The water required for cutting a workpiece is taken from a water tank 5 via a connected to the high-pressure pump 1 suction line 6 and conveyed by a pressure side connected to the high-pressure pump 1 high-pressure line 7 a cutting head 8. This cutting head 8 comprises a pure water nozzle 9 for generating a water jet for cutting the workpiece. Abrasive can be added to the water jet emerging from the pure water nozzle 9, if necessary, in order to increase the cutting performance, as indicated by the arrow 10. The pure water nozzle 9 is preceded by a cutting head valve 11, via the actuator 12 of the cutting head 8 can be switched on and off.

Zur Drehzahlregelung des Servomotors 4 wird der dem Servomotor 4 zugehörige Servoumrichter 13 über einen Drehzahlgeber 14 beaufschlagt. Die Ansteuerung des Servoumrichters 13 erfolgt durch einen Regler 15 mit einem Sollwertgeber 16 für den Druck in der Hochdruckleitung 7. Außerdem wird der Istwert des Drucks in der Hochdruckleitung 7 über einen an die Hochdruckleitung 7 angeschlossenen Istwertgeber 17 erfasst und an den Regler 15 weitergeleitet, sodass der Servoumrichter 13 in Abhängigkeit von der Soll-Istwertdifferenz des Drucks in der Hochdruckleitung 7 angesteuert werden kann.To control the speed of the servomotor 4, the servomotor 4 associated Servoumrichter 13 is acted upon by a speed sensor 14. The control of the servo 13 is carried out by a controller 15 with a setpoint generator 16 for the pressure in the high-pressure line 7. In addition, the actual value of the pressure in the high pressure line 7 is detected via a connected to the high-pressure line 7 actual value 17 and forwarded to the controller 15, so the servo-converter 13 can be controlled as a function of the desired-actual-value difference of the pressure in the high-pressure line 7.

Wird das Schneidkopfventil 11 über den Stelltrieb am Ende eines Schneidvorgangs geschlossen, so steigt der Druck in der Hochdruckleitung 7 schlagartig an, was zu einem Abschalten des Servomotors 4 über den Regler 15 führt, wobei der Druck in der Hochdruckleitung 7 aufrecht bleibt und folglich für den nachfolgenden Schneidvorgang wieder zur Verfügung steht.If the cutting head valve 11 is closed by the actuator at the end of a cutting process, the pressure in the high pressure line 7 abruptly increases, resulting in a shutdown of the servo motor 4 via the controller 15, wherein the pressure in the high pressure line 7 is maintained and thus for the subsequent cutting process is available again.

Zum Einleiten des nachfolgenden Schneidvorgangs ist das Schneidkopfventil 11 über den Stelltrieb 12 wieder zu öffnen und zugleich der Servomotor 4 auf die dem Sollwert des Drucks in der Hochdruckleitung 7 zugehörige Pumpendrehzahl zu beschleunigen, und zwar innerhalb der Öffnungszeit für das Schneidkopfventil 11, was über eine gemeinsam mit der Ansteuerung des Stelltriebs 12 für das Schneidkopfventil 11 erfolgende Ansteuerung des Servoumrichters 13 ohne weiteres möglich ist. Dies bedeutet, dass der neue Schneidvorgang mit einem Förderdruck des Wassers in der Hochdruckleitung 7 begonnen werden kann, der zumindest angenähert dem Sollwert entspricht, sodass sich keine Änderungen im Schnittbild während des Schneidvorgangs ergeben.To initiate the subsequent cutting operation, the cutting head valve 11 is to be opened again via the actuator 12 and at the same time to accelerate the servo motor 4 to the setpoint of the pressure in the high-pressure line 7 associated pump speed, and that within the opening time for the cutting head valve 11, which in common with the control of the actuator 12 for the cutting head valve 11 taking place control of the servo 13 is readily possible. This means that the new cutting process can be started with a delivery pressure of the water in the high pressure line 7, which at least approximately corresponds to the desired value, so that there are no changes in the sectional image during the cutting process.

Sind aufgrund der Schneidbedingungen eines nachfolgenden Schneidvorgangs die Sollwerte für den Druck in der Hochdruckleitung 7 zu verringern, so kann mit einer entsprechenden Sollwertvorgabe in der vorausgehenden Schneidpause der Druck in der Hochdruckleitung 7 über ein Druckminderungsventil 18 in einer an die Hochdruckleitung 7 angeschlossenen Rücklaufleitung 19 abgesenkt werden. Wird das Druckminderungsventil 18 nicht benötigt, so kann die Rücklaufleitung 19 über das Druckminderungsventil 18 gesperrt werden, wenn sein Stelltrieb 20 entsprechend angesteuert wird.If the setpoint values for the pressure in the high-pressure line 7 are to be reduced on account of the cutting conditions of a subsequent cutting operation, the pressure in the high-pressure line 7 can be lowered by means of a pressure reduction valve 18 in a return line 19 connected to the high-pressure line 7 with a corresponding setpoint specification in the preceding cutting break , If the pressure reducing valve 18 is not needed, then the return line 19 can be locked via the pressure reducing valve 18 when its actuator 20 is driven accordingly.
