Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Regelung eines doppeltwirkenden ein- oder mehrstufigen Kolbenverdichters.The invention relates to a device and a method for controlling a double-acting single or multi-stage piston compressor.

Aus der DE 10 2004 052 168 A1 ist eine Kolbenverdichtermaschine bekannt, die ein- oder doppelstufig ausgebildet ist und durch einen Linearmotor als Linearantrieb angetrieben wird. Dabei werden über Sensoren die Drücke und Temperaturen erfasst. Über die erfassten Messdaten und die Kompressorregelung wird eine Regelung des Verdichters durchgeführt.From the DE 10 2004 052 168 A1 a reciprocating compressor machine is known, which is formed in one or two stages and is driven by a linear motor as a linear drive. The pressures and temperatures are recorded via sensors. The recorded measured data and the compressor control are used to control the compressor.

Wird bei einem doppeltwirkenden Kolbenverdichter zur Reduzierung der Liefermenge von komprimiertem Gas konstruktiv nur eine Kolbenseite, z. B. die Deckelseite, zur Förderung genutzt, muss die entgegengesetzte Seite, in dem Fall die Kurbelseite, zur Atmosphäre wie bei doppelseitiger Verdichtung mittels einer Kolbenstangendichtung abgedichtet werden. Kurbelseitig sind keine Arbeitsventile vorhanden. Das Gas wird beim Rücklauf des Kolbens nicht ausgeschoben und somit komprimiert. Durch einen vorgesehenen Ausgleichsraum in der Größe des Hubvolumens wird eine Verdichtung des Gases reduziert.Is in a double-acting piston compressor to reduce the supply of compressed gas constructively only one side of the piston, z. As the lid side, used for promotion, the opposite side, in the case the crank side, to the atmosphere as in double-sided compression must be sealed by means of a piston rod seal. There are no working valves on the crank side. The gas is not expelled during the return of the piston and thus compressed. By a planned compensation chamber in the size of the stroke volume, a compression of the gas is reduced.

Einerseits besteht bei der zuvor beschriebenen Vorrichtung ein Nachteil im großen technischen Aufwand, andererseits besteht bei dem Verfahren der Nachteil in der Erwärmung des Gases im Ausgleichsraum, weil hier kein Gasaustausch stattfindet.On the one hand there is a disadvantage in the device described above in the great technical effort, on the other hand, in the method, the disadvantage in the heating of the gas in the expansion chamber, because there is no gas exchange.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, dass die Verdichtung eines Kolbenverdichters ohne großen technischen Aufwand verbessert wird, und ein Verfahren anzugeben, dass die Regelung eines solchen Kolbenverdichters besser ausgestaltet wird.The invention has for its object to provide a device that the compression of a reciprocating compressor is improved without much technical effort, and a method indicate that the control of such a reciprocating compressor is better designed.

Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1 und ein Verfahren nach den Merkmalen des Patentanspruchs 6 gelöst.According to the invention the object is achieved by a device having the features of patent claim 1 and a method according to the features of patent claim 6.

Die Vorrichtung eines doppeltwirkenden ein- oder mehrstufigen Kolbenverdichters hat den Vorteil, dass die Saugseite der deckelseitigen Zylinderseite mit der kurbelseitigen Zylinderseite verbunden ist und damit die kurbelseitige Zylinderseite druckentlastet wird.The device of a double-acting single-stage or multistage piston compressor has the advantage that the suction side of the cover-side cylinder side is connected to the crank-side cylinder side and thus the crank-side cylinder is depressurized.

Darüber hinaus hat sich als vorteilig herausgesellt, dass eine Verbindungsleitung einer fluidischen Vorrichtung die Verbindung der Saugseite der deckseitigen Zylinderseite mit der kurbelseitigen Zylinderseite herstellt.In addition, it has turned out to be advantageous that a connecting line of a fluidic device establishes the connection of the suction side of the top-side cylinder side with the crank-side cylinder side.

Weiterhin hat sich als vorteilig erwiesen, dass in der Verbindungsleitung der fluidischen Vorrichtung zumindest ein erstes Ventil angeordnet ist.Furthermore, it has proved to be advantageous that at least a first valve is arranged in the connecting line of the fluidic device.

Weiter ist besonders vorteilig, wenn in der Saugleitung der Saugseite der deckelseitigen Zylinderseite zumindest ein zweites Ventil angeordnet ist.It is also particularly advantageous if at least one second valve is arranged in the suction line of the suction side of the cylinder side on the cover side.

Dabei ist es vorteilig, wenn das zweite Ventil in der Saugleitung der Saugseite vor der Einmündung der Verbindungsleitung der fluidischen Vorrichtung in die Saugleitung in Richtung auf die Saugseite der deckelseitigen Zylinderseite gesehen angeordnet ist.It is advantageous if the second valve is arranged in the suction line of the suction side before the confluence of the connecting line of the fluidic device in the suction line in the direction of the suction side of the cover side cylinder side.

Bei dem Verfahren ist es von Vorteil, dass das Gas im Zylinder auf der deckelseitigen Zylinderseite beim Bewegen des Kolbens durch die Kolbenstange im Zylinder in Richtung der deckelseitigen Zylinderseite verdichtet wird und beim Überschreiten eines vorbestimmten Zwischen- oder Enddruckes aus der Druckleitung der deckelseitigen Druckseite ausgeschoben wird und gleichzeitig über die Saugleitung der deckelseitigen Saugseite ein Gas in die kurbelseitige Zylinderseite gesaugt wird.In the method, it is advantageous that the gas in the cylinder on the cover-side cylinder side is compressed when moving the piston by the piston rod in the cylinder in the direction of the cover-side cylinder side and when exceeding a predetermined intermediate or final pressure is pushed out of the pressure line of the cover-side pressure side and at the same time via the suction line of the cover-side suction side, a gas is sucked into the crank side cylinder.

Ein weiterer Vorteil bei dem Verfahren besteht darin, dass das Gas aus der kurbelseitigen Zylinderseite über die Verbindungsleitung der fluidischen Vorrichtung zur deckelseitigen Zylinderseite beim Bewegen des Kolbens nach Durchfahren des oberen Totpunktes in Richtung der kurbelseitigen Zylinderseite geführt und die kurbelseitige Zylinderseite druckentspannt wird.Another advantage of the method is that the gas from the crank-side cylinder side via the connecting line of the fluidic device to the cover-side cylinder side when moving the piston after passing through the top dead center in the direction of the crank-side cylinder side out and the crank-side cylinder side is pressure-relieved.

Ein noch weiterer Vorteil des Verfahrnes zeigt sich darin, dass das Gas auf der kurbelseitigen Zylinderseite beim Zurückfahren des Kolbens in den unteren Totpunkt durch Sperren des ersten Ventils in der Verbindungsleitung der fluidischen Vorrichtung verdichtet und gleichzeitig die deckelseitige Zylinderseite mit Gas von der Saugleitung gefüllt wird. Ganz nach Position des Kolbens oder einer vorbestimmten Vorverdichtung wird das erste Ventil in der Verbindungsleitung der fluidischen Vorrichtung geöffnet und zeitgleich das zweite Ventil in der Saugleitung geschlossen. Dabei wird das vorverdichtete Gas, das den Druck in der Saugleitung übersteigt, in die deckelseitige Zylinderseite geschoben.A still further advantage of the method is shown in the fact that the gas is compressed on the crank side cylinder when returning the piston to the bottom dead center by blocking the first valve in the connecting line of the fluidic device and at the same time the top side cylinder is filled with gas from the suction line. Depending on the position of the piston or a predetermined pre-compression, the first valve in the connecting line of the fluidic device is opened and at the same time the second valve in the suction line is closed. In this case, the pre-compressed gas, which exceeds the pressure in the suction line, pushed into the lid side cylinder.

Weitere Merkmale und Vorteile der Erfindung sind in der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der beigefügten Zeichnung erläutert.Further features and advantages of the invention are explained in the following description of a preferred embodiment with reference to the accompanying drawings.

Dabei zeigt:

  • Fig. I einen Schnitt der erfindungsgemäßen Vorrichtung mit einer fluidischen Vorrichtung zur kurbelseitigen Druckentlastung des Zylinderinnendrucks; und
  • Fig. II einen Schnitt der erfindungsgemäßen Vorrichtung mit einer fluidischen Vorrichtung und einer Anordnung von Ventilen zur saugseitigen Druckerhöhung des Gases und damit zur Reduzierung des Stufendruckverhältnisses.
Showing:
  • Fig. I a section of the device according to the invention with a fluidic device for crank-side pressure relief of the cylinder internal pressure; and
  • Fig. II shows a section of the device according to the invention with a fluidic device and an arrangement of valves for suction-side pressure increase of the gas and thus to reduce the step pressure ratio.

Fig. I zeigt einen Zylinder 01, in dem ein an einer Kolbenstange 03 angeordneter Kolben 02 achsparallel zwischen einer deckelseitigen Zylinderseite 04 und einer kurbelseitigen Zylinderseite 05 geführt ist. Die deckelseitige Zylinderseite 04 ist über eine Verbindungsleitung 06 einer fluidischen Vorrichtung mit der kurbelseitigen Zylinderseite 05 verbunden. Weiterhin ist die Verbindungsleitung 06 der fluidischen Vorrichtung mit einer Saugleitung 07 einer Saugseite verbunden, die an der deckelseitigen Zylinderseite 04 angeordnet ist. Die deckelseitige Zylinderseite 04 ist weiterhin mit einer Druckleitung 08 einer Druckseite versehen, die an der deckelseitigen Zylinderseiteseite angebracht ist. Fig. I 1 shows a cylinder 01 in which a piston 02 arranged on a piston rod 03 is guided parallel to the axis between a cylinder side 04 on the cover side and a cylinder side 05 on the crank side. The cover-side cylinder 04 is connected via a connecting line 06 of a fluidic device with the crank-side cylinder 05. Furthermore, the connecting line 06 of the fluidic device is connected to a suction line 07 a suction side, which is arranged on the cover-side cylinder side 04. The cover-side cylinder 04 is further provided with a pressure line 08 a pressure side, which is attached to the cover-side cylinder side.

Die Fig. II zeigt die gleichen Elemente wie Fig. I und wird daher nicht weiter beschrieben. In der Verbindungsleitung 06 der fluidischen Vorrichtung ist ein erstes Ventil 09 angeordnet. Weiterhin ist ein zweites Ventil 10 in der Saugleitung 07 der Saugseite der deckelseitigen Zylinderseite 04 vor der Einmündung der Verbindungsleitung 06 der fluidischen Vorrichtung in die Saugleitung angebracht, und zwar in Richtung auf die Saugseite der deckelseitigen Zylinderseite 04 gesehen.Fig. II shows the same elements as Fig. I and will therefore not be described further. In the connecting line 06 of the fluidic device, a first valve 09 is arranged. Furthermore, a second valve 10 is mounted in the suction line 07 of the suction side of the cover side cylinder side 04 in front of the junction of the connecting line 06 of the fluidic device in the suction line, and seen in the direction of the suction side of the cover side cylinder side 04.

Die Vorrichtung eines ein- oder mehrstufigen Kolbenverdichters umfasst also wenigstens einen Zylinder 01 mit einem Kolben 02 und einer Kolbenstange 03 sowie eine deckelseitige Zylinderseite 04 und eine kurbelseitige Zylinderseite 05. In einem Arbeitstakt wird der Kolben 02 durch die Kolbenstange 03 in dem Zylinder 01 in Richtung der deckelseitigen Zylinderseite 04 bewegt. Dabei wird das Gas in dem Zylinder 01 auf der deckelseitigen Zylinderseite 04 verdichtet und beim Überschreiten eines vorbestimmten Zwischen- oder Enddruckes aus der Druckleitung 08 der Druckseite der deckelseitigen Zylinderseite 04 ausgeschoben. Gleichzeitig wird über die Saugleitung 07 der Saugseite der deckelseitigen Zylinderseite 04 Gas in die kurbelseitige Zylinderseite 05 gesaugt.The device of a single-stage or multistage piston compressor thus comprises at least one cylinder 01 with a piston 02 and a piston rod 03 and a cover-side cylinder 04 and a crank-side cylinder 05. In a power stroke of the piston 02 by the piston rod 03 in the cylinder 01 in the direction the lid-side cylinder 04 moves. The gas is in the cylinder 01 compressed on the cover side cylinder side 04 and ejected when exceeding a predetermined intermediate or final pressure from the pressure line 08 of the pressure side of the cover side cylinder side 04. At the same time, gas is sucked into the crank-side cylinder side 05 via the suction line 07 of the suction side of the cover-side cylinder side 04.

Bewegt sich der Kolben 02 in einem nächsten Arbeitstakt nach Durchfahren des oberen Totpunktes in Richtung kurbelseitiger Zylinderseite 05, wird das Gas aus der kurbelseitigen Zylinderseite 05 über die Verbindungsleitung 06 der fluidische Vorrichtung zur deckelseitigen Zylinderseite 04 geführt und die kurbelseitige Zylinderseite 05 somit druckentspannt.Moves the piston 02 in a next cycle after passing through the top dead center in the direction of crank side cylinder side 05, the gas from the crank side cylinder 05 is guided over the connecting line 06 of the fluidic device to the cover side cylinder side 04 and the crank side cylinder 05 thus pressure-relieved.

Weiterhin kann durch die Nutzung eines Vordruckes das Stufendruckverhältnis auf der deckelseitigen Zylinderseite 04 reduziert werden, wodurch sich die Verdichtungstemperatur verringert. Die Reduzierung der Verdichtungstemperatur wirkt sich gerade bei einatomigen Gasen, wie z. B. Helium und Argon, mit einem hohen Isentropenexponenten bei der Kompression vorteilhaft auf die Wärmeentwicklung aus.Furthermore, by using a pre-pressure, the stage pressure ratio on the cover-side cylinder side 04 can be reduced, whereby the compression temperature is reduced. The reduction of the compression temperature affects straight with monatomic gases, such as. As helium and argon, with a high isentropic component in the compression of the heat development advantageous.

Weiter wirkt sich eine Vorverdichtung des Gases zur Liefermengenregelung vorteilhaft aus. Hierbei wird das Gas auf der kurbelseitigen Zylinderseite 05 beim Zurückfahren des Kolbens 02 in den unteren Totpunkt verdichtet, da das Gas durch das gesperrte erste Ventil 09 in der Verbindungsleitung 06 der fluidischen Vorrichtung nicht in die Saugleitung 07 der Saugseite der deckelseitigen Zylinderseite 04 fließen kann.Furthermore, a pre-compression of the gas for delivery quantity control has an advantageous effect. In this case, the gas is compressed on the crank side cylinder 05 during retraction of the piston 02 in the bottom dead center, since the gas can not flow through the locked first valve 09 in the connecting line 06 of the fluidic device in the suction line 07 of the suction side of the cover side cylinder side 04.

Gleichzeitig wird die deckelseitige Zylinderseite 04 mit Gas von der Saugleitung 07 gefüllt. Je nach Position des Kolbens 02 und damit einer vorbestimmten Vorverdichtung wird das erste Ventil 09 in der Verbindungsleitung 06 der fluidischen Vorrichtung geöffnet und zeitgleich das zweite Ventil 10 in der Saugleitung 07 geschlossen. Dadurch wird das auf der kurbelseitigen Zylinderseite 05 vorverdichtete Gas in die deckelseitige Zylinderseite 04 geschoben und der Druck auf der Saugseite der deckelseitigen Zylinderseite 04 gegenüber einem ungeregelten Saugdruck angehoben.At the same time, the cover-side cylinder 04 is filled with gas from the suction line 07. Depending on the position of the piston 02 and thus a predetermined pre-compression, the first valve 09 in the connecting line 06 of the fluidic Open device and at the same time the second valve 10 in the suction line 07 closed. As a result, the gas pre-compressed on the crank-side cylinder 05 is pushed into the cover-side cylinder side 04 and the pressure on the suction side of the cover-side cylinder side 04 is raised relative to an unregulated suction pressure.

Dabei wird durch die Regelung der kurbelseitigen Vorverdichtung die Liefermenge des komprimierten Gases angepasst und gleichzeitig durch die Verringerung des Stufendruckverhältnisses die Verdichtungswärme reduziert.In this case, the supply quantity of the compressed gas is adjusted by the control of the crank-side pre-compression and at the same time reduces the heat of compression by reducing the step pressure ratio.
