Description
Die Erfindung betrifft einen Kolbenkompressor mit mindestens einem Kompressionszylinder mit einem Kolben sowie mit einem Druckanschluss und einem Sauganschluss.The invention relates to a piston compressor with at least one compression cylinder with a piston and with a pressure port and a suction port.
Die Kompressionszylinder solcher Kolbenkompressoren, die für Drücke von ca. 20 bar bis 450 bar ausgelegt sind, werden häufig nicht mehr als Sandformguss hergestellt.The compression cylinders of such reciprocating compressors, which are designed for pressures of about 20 bar to 450 bar, are often no longer produced as a sand mold casting.
Als Halbzeuge kommen geschmiedete Stahlblöcke oder für niedrige Druckbereiche bis zu Bohrungsdurchmessern von etwa 500 mm auch gusseiserne Blöcke, Kokillen bzw. einfache Modellgussblöcke zur Anwendung.As semi-finished forged steel blocks or for low pressure ranges up to bore diameters of about 500 mm cast-iron blocks, molds or simple model casting blocks are used.
Bei dieser Art der Zylinderkonstruktion müssen alle Gasräume und Kanäle, die beim üblichen Modellguss durch das Einlegen der Sandkerne gebildet werden, durch teilweise aufwendige Bohrungen oder Fräsarbeiten während der mechanischen Fertigung eingebracht werden.In this type of cylinder design, all gas chambers and channels that are formed in the conventional model casting by inserting the sand cores must be introduced by partially consuming drilling or milling during mechanical manufacturing.
So muss z. B. bei doppelt wirkenden Kompressionszylindern die Verbindung der deckel- und kurbelseitigen Ventilkammern durch eine Längsbohrung hergestellt werden.So z. B. in double-acting compression cylinders, the connection of the cover and crank-side valve chambers are made by a longitudinal bore.
Diese Verbindungsbohrungen müssen am stirnseitigen Ende der Kompressionszylinder durch Deckel - ähnlich den Ventildeckeln - gasdicht verschlossen werden. Diese gasdichte Ausführung erfordert insbesondere bei hohen Betriebsdrücken eine aufwendige konstruktive Lösung.These connecting bores must be sealed gas-tight at the front end of the compression cylinder by cover - similar to the valve covers. This gas-tight design requires especially at high operating pressures a complex design solution.
Die Saug- und Druckanschlüsse sind im Bereich zwischen den jeweiligen Ventilkammern oder direkt an den betreffenden Ventilkammern angeordnet. Die Zugänglichkeit des den Kompressionszylinder umgebenden Raums wird durch die von den Saug- und Druckanschlüssen abgehenden Druck- und Saugrohren stark beeinträchtigt.The suction and pressure ports are located in the area between the respective valve chambers or directly to the respective valve chambers. The accessibility of the space surrounding the compression cylinder is greatly impaired by the pressure and suction pipes emerging from the suction and pressure ports.
Die
Der Kompressionszylinder 10 besitzt mittig eine Zylinderkammer 25, in der der Kolben 30 in Längsrichtung beweglich angeordnet ist. Beidseitig des Kolbens 30 werden zwei Kompressionsräume 20a, 20b gebildet. Stirnseitig ist diese Zylinderkammer 25 durch einen Zylinder-Deckel 13 gasdicht abgeschlossen. Der Kompressionszylinder 10 besitzt in der Zylinderwand 24 einen Sauganschluss 18 und gegenüberliegend einen Druckanschluss 19, die jeweils in einen Verbindungskanal 17a bzw. 17b münden. An den beiden Enden der sich in Längsrichtung parallel zur Längsachse erstreckenden Verbindungskanäle 17a, 17b sind jeweils Ventilkammern 15a bis 15d mit Ventilen 16a bis 16d angeordnet, die über entsprechende Kanäle mit der Zylinderkammer 25 verbunden sind. Herstellungsbedingt sind die Verbindungskanäle 17a und 17 b benachbart zu den Ventilkammern 15b, 15c Kammern 22a und 22b stirnseitig offen. Sie müssen also durch separate Deckel 14a, 14b an der vorderen Stirnseite 12a verschlossen werden. An der hinteren Stirnseite 12b wird der Zylinderraum 25 mittels eines Deckels 26 mit einer Abdichtung für die Kolbenstange 32 abgeschlossen. Bei einer anderen Konstruktionsart wird der Zylinderraum 25 als SacklochBohrung ausgeführt. In diesem Fall wird die Kolbenstange mittels einer kleineren Bohrung durch den Zylinderboden geführt. Der abschließende Deckel 26 entfällt somit.The
Die seitlichen Anschlüsse 18 und 19 haben einen erheblichen Einfluss auf die äußeren Abmessungen des Kompressionszylinders 10. Wesentliche Nachteile dieser Konstruktion liegen in einer Vergrößerung der Halbzeuge sowie in einer starken Einschränkung der Begehbarkeit bei vertikal angeordneten Kompressoranlagen. Bei horizontalen Kompressoren, deren Kompressionszylinder häufig zum Fundament hin abgestützt werden, behindern häufig die unterhalb des Druckstutzens liegenden Behälter diese Abstützung.The
Es ist daher Aufgabe der Erfindung, einen Kompressor bereitzustellen, der kompakter und platzsparender sowie kostengünstiger ausgestaltet ist.It is therefore an object of the invention to provide a compressor that is designed to be more compact and space-saving and cost-effective.
Diese Aufgabe wird mit einem Kompressor gelöst, der dadurch gekennzeichnet ist, dass der Druckanschluss und der Sauganschluss an einer Stirnseite des Kompressionszylinders angeordnet sind.This object is achieved with a compressor, which is characterized in that the pressure port and the suction port are arranged on an end face of the compression cylinder.
Aufgrund der veränderten Anordnung der Saug- und Druckanschlüsse werden sowohl die Kompressionszylinder- als auch die Kolbenlänge erheblich verkürzt, was die Beschaffungskosten der Halbzeuge entsprechend reduziert. Gleiches gilt für die Zylinderlaufbuchse und die Kolbenstange.Due to the changed arrangement of the suction and pressure connections, both the compression cylinder and the piston length are shortened considerably, which correspondingly reduces the procurement costs of the semi-finished products. The same applies to the cylinder liner and the piston rod.
Aufgrund der geringen Masse der Zylinder und der aus der Zylinderverkürzung resultierenden geringen Kolbenmasse werden sowohl die statische Belastung für das Fundament als auch die dynamisch wirkenden Massenkräfte der Maschine deutlich reduziert.Due to the low mass of the cylinder and the resulting from the cylinder shortening low piston mass both the static load on the foundation and the dynamically acting mass forces of the machine are significantly reduced.
Insbesondere bei vertikalen Kompressoranlagen kann durch die erfinderische Anordnung von Saug- und Druckanschluss die Rohrleitungsführung so verändert werden, dass ein ausreichender Arbeitsraum für Inspektion und Montagearbeiten zur Verfügung steht.In particular, in vertical compressor systems can be changed by the inventive arrangement of suction and pressure connection, the pipe guide so that a sufficient working space for inspection and installation work is available.
Vorzugsweise weist der Kompressionszylinder eine einseitig am Kolben angeordnete Kolbenstange auf, wobei der Druckanschluss und der Sauganschluss an der der Kolbenstange abgewandten Stirnseite des Kompressionszylinders angeordnet sind. Die Anschlüsse liegen in einer frei zugänglichen Stirnseite, nämlich der vorderen Stirnseite des Kompressionszylinders, was die Rohrleitungsführung weiter vereinfacht.Preferably, the compression cylinder has a piston rod arranged on one side on the piston, wherein the pressure connection and the suction connection are arranged on the end face of the compression cylinder facing away from the piston rod. The connections are in a freely accessible end, namely the front end side of the compression cylinder, which further simplifies the piping.
Vorzugsweise ist der Kompressionszylinder ein doppelt wirkender Kompressionszylinder.Preferably, the compression cylinder is a double-acting compression cylinder.
Bei dieser Ausführungsform weist der Kompressionszylinder vorzugsweise saugseitig und druckseitig jeweils zwei in Richtung der Zylinderachse beabstandet angeordnete Ventilkammern auf, die über jeweils einen nach außen abgeschlossenen Verbindungskanal miteinander verbunden sind. Unter einem nach außen abgeschlossenen Verbindungskanal wird ein Kanal verstanden, der z. B. nicht über seitliche Bohrungen oder Kanäle zugänglich ist. Jeweils eine druckseitige Ventilkammer ist über eine Anschlusskammer mit dem Druckanschluss und eine saugseitige Ventilkammer ist über eine Anschlusskammer mit dem Sauganschluss verbunden.In this embodiment, the compression cylinder preferably on the suction side and the pressure side in each case two spaced in the direction of the cylinder axis valve chambers, which are connected to each other via a respective outwardly closed connection channel. Under a closed to the outside connection channel is a channel understood, the z. B. is not accessible via lateral holes or channels. In each case, a pressure-side valve chamber is connected to the pressure connection via a connection chamber and a suction-side valve chamber is connected to the suction connection via a connection chamber.
Durch den Wegfall der seitlich an der Zylinderwand vorgesehenen Anschlüsse können die Verbindungskanäle, die Zylinderkammer und der Kolben deutlich kürzer ausgeführt werden. Es sind Verkürzungen von 20 % bis zu 30 % möglich.By eliminating the side of the cylinder wall provided connections, the connecting channels, the cylinder chamber and the piston can be made significantly shorter. Shortening from 20% up to 30% is possible.
Die Verlegung der Anschlüsse an die Stirnseite kann insbesondere bei den doppelt wirkenden Kompressionszylindern für eine deutlich kompaktere Bauweise genutzt werden.The laying of the connections to the front side can be used in particular for the double-acting compression cylinders for a much more compact design.
Vorzugsweise besteht der Kompressionszylinder aus Stahl, insbesondere aus Schmiedestahl, wobei der Verbindungskanal und die Anschlusskammer durch eine einzige Bohrung gebildet sind. Der Herstellvorgang wird erheblich vereinfacht, weil die zusätzliche Herstellung gesonderter Rohrleitungsanschlüsse an der Zylinderwand entfällt.Preferably, the compression cylinder made of steel, in particular forged steel, wherein the connecting channel and the connection chamber are formed by a single bore. The manufacturing process is considerably simplified because the additional production of separate pipe connections on the cylinder wall is eliminated.
Kompressoren mit solchen aus Schmiedestahl bestehenden Kompressionszylindern werden vorzugsweise in Druckbereichen von 100 bar bis 450 bar eingesetzt.Compressors with such forged steel existing compression cylinders are preferably used in pressure ranges from 100 bar to 450 bar.
Gemäß einer weiteren Ausführungsform besteht der Kompressionszylinder aus einem gusseisernen Block. Die Verbindungskanäle und die Anschlusskammern werden auch hier entsprechend dem Stahlzylinder durch mechanische Bearbeitung hergestellt.According to a further embodiment, the compression cylinder consists of a cast-iron block. The connecting channels and the connecting chambers are also manufactured here according to the steel cylinder by mechanical processing.
Kompressoren mit derartigen Kompressionszylindern werden vorzugsweise im Bereich von 20 bar bis 99 bar eingesetzt.Compressors with such compression cylinders are preferably used in the range of 20 bar to 99 bar.
Die durch die geänderte Anordnung der Saug- und Druckanschlüsse erzielte Kostenreduzierung kann dadurch noch gesteigert werden, dass die Verbindungskanäle über einfachen Modellguss lediglich vorgegossen, nicht aber mehr mechanisch bearbeitet werden.The achieved by the changed arrangement of the suction and pressure connections cost reduction can be further increased that the connection channels only precast over simple model casting, but not machined more.
Die erfindungsgemäßen Zylinder sind in horizontalen, vertikalen als auch in Kompressoren in V-Bauart verwendbar.The cylinders according to the invention can be used in horizontal, vertical as well as in compressors in V-type.
Solche Kompressoren werden bei der Verdichtung sämtlicher Gase, vorzugsweise in der chemischen, petrochemischen, und in der pharmazeutischen Industrie als auch bei der Erdgasspeicherung eingesetzt.Such compressors are used in the compression of all gases, preferably in the chemical, petrochemical, and in the pharmaceutical industry as well as in natural gas storage.
