Description

Die Erfindung betrifft einen Seitenkanalverdichter, mit mindestens einem in jeweils einem geteilten Laufradgehäuse umlaufenden Laufrad, an welchem Laufradgehäuse sich mindestens zwei in Umfangsrichtung befindliche, kreissektorähnliche Anschlußbereiche befinden, von denen jeder zumindest eine Einlaß bzw. eine Auslaßöffnung auf beiden in axialer Richtung des Laufrades gegenüberliegenden Seiten des Laufradgehäuses aufweist.The invention relates to a side channel compressor, with at least one rotating in a split impeller housing Impeller, on which impeller housing at least two circumferential, circular sector-like connection areas are located, each of which has at least one inlet or an outlet opening on both in the axial direction of the impeller opposite sides of the impeller housing having.

Ein solcher Verdichter ist durch die DE-C-43 41 266 bekannt. Bei diesem Verdichter weisen die Anschlußbereiche jeweils nur eine Einlaßöffnung bzw. eine Auslaßöffnung auf. Damit können an den Seitenkanalverdichter anzuschließende Rohrleitungen nur aus einer Richtung an das Verdichtergehäuse herangeführt werden. Aus der DE 2 721 233 ist ein aus mehreren Verdichterstufen bestehender Seitenkanalverdichter bekannt, bei dem die aus jeweils zwei Gehäusehälften bestehenden Gehäuse der einzelnen Verdichterstufen axial nebeneinander angeordnet sind und axial ausgerichtete Ein- und Auslaßöffnungen gleicher Form und Größe haben. Man ist somit in der Rohrleitungsführung eingeengt bzw. es muß bereits bei der Herstellung oder Anschaffung eines Verdichters die Anschlußrichtung für die Rohrleitungen bekannt sein bzw. festgelegt werden.Such a compressor is known from DE-C-43 41 266. In this compressor, the connection areas only have an inlet opening or an outlet opening. So that can Pipes to be connected to the side channel blower only brought to the compressor housing from one direction become. DE 2 721 233 describes one of several compressor stages existing side channel blower known, in which the each consisting of two housing halves Compressor stages are arranged axially next to one another and axially aligned inlet and outlet openings the same Have shape and size. So you are in the piping concentrated or it must already be in the manufacture or Purchase of a compressor the connection direction for the Pipelines are known or specified.

Der Erfindung liegt die Aufgabe zugrunde, einen Seitenkanalverdichter so auszugestalten, daß ein Anschluß der notwendigen Rohrleitungen in verschiedenen Richtungen möglich ist.The invention has for its object a side channel compressor To be designed so that a connection of the necessary Piping in different directions is possible.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß jeder Anschlußbereich zusätzlich in einer im wesentlichen radialen Richtung des Laufrades je eine Einlaßbzw. Auslaßöffnung. Hierdurch ist ein Anschluß in der einen oder anderen Achsrichtung möglich. Durch das Vorsehen einer Ein- und Auslaßöffnung auch am Umfang des Laufradgehäuses wird ein weiterer Freiheitsgrad bei der Anschlußrichtung der Rohrleitungen erreicht.The problem is solved according to the invention in that each connection area additionally in an essentially radial direction of the impeller each an inlet or Outlet opening. This is a connection in one or other axis direction possible. By providing one Inlet and outlet opening also on the circumference of the impeller housing is another degree of freedom in the connection direction of the Pipelines reached.

Mehrstufige Verdichter werden durch Aneinanderreihen einzelner Gehäuse gebildet.Multi-stage compressors are created by stringing together individual ones Housing formed.

Erstrecken sich die Anschlußbereiche hinsichtlich ihrer axialen Breite mindestens bis in die Trennebene der Laufradgehäuse, dann ist eine direkte Verbindung der entsprechenden Einbzw. Auslaßöffnungen der einzelnen Verdichter möglich, da die Öffnungen in axialer Richtung direkt aneinander anliegen und somit keine Rohrteile als Zwischenverbindung erforderlich sind.Extend the connection areas with regard to their axial Width at least up to the parting plane of the impeller housing, then a direct connection of the corresponding involvement. Outlet openings of the individual compressors possible because the Openings lie directly against each other in the axial direction and therefore no pipe parts required as an intermediate connection are.

Vorteilhaft es es auch, wenn die Anschlußbereiche zu einem Anschlußblock zusammengefaßt sind. Hierdurch ergibt sich eine höhere mechanische Festigkeit.It is also advantageous if the connection areas become one Terminal block are summarized. This results in a higher mechanical strength.

Dadurch, daß am Laufradgehäuse mindestens eine in ihrer Form und Größe der Form und Größe der Einlaß- bzw. Auslaßöffnung angepaßte Dichtfläche in einem dem zwischen der Einlaß- und der Auslaßöffnung bestehenden Winkelabstand entsprechenden Winkelabstand zur Einlaß- bzw. Auslaßöffnung angeordnet ist, besteht bei mehreren auf einer gemeinsamen Antriebswelle angeordneten Verdichtern die Möglichkeit, die einzelnen Laufradgehäuse um einen dem Winkelabstand entsprechenden Winkel gegeneinander zu verdrehen, wobei dann die dem Laufradgehäuse des benachbarten Verdichters zugewandte Ein- und Auslaßöffnung durch die Dichtfläche des jeweils anderen Laufradgehäuses verschlossen wird. Damit entfällt ein gesondertes Verschließen der fraglichen Öffnungen. Es besieht aber auch die Möglichkeit, die Einlaßöffnung des einen Verdichters mit der Auslaßöffnung des anderen Verdichters zur Deckung zu bringen und somit zwei Verdichter in Reihe zu schalten. Die Auslaßöffnung des einen Verdichters und die Einlaßöffnung des anderen Verdichters werden dabei durch die entsprechende Dichtfläche des jeweils anderen Laufradgehäuses verschlossen, ohne daß es hierzu gesonderter Maßnahmen bedarf.Characterized in that at least one in shape on the impeller housing and size of the shape and size of the inlet or outlet opening adapted sealing surface in a between the inlet and the existing angular distance corresponding to the outlet opening Angular distance to the inlet or outlet opening is arranged, consists of several arranged on a common drive shaft Compress the possibility of the individual Impeller housing at an angle corresponding to the angular distance to rotate against each other, then the impeller housing of the neighboring compressor facing inlet and Outlet opening through the sealing surface of the other Impeller housing is closed. This eliminates a separate one Closing the openings in question. But it looks also the possibility of the inlet opening of a compressor to cover with the outlet of the other compressor bring and thus connect two compressors in series. The Outlet opening of a compressor and the inlet opening of the other compressors are replaced by the corresponding Sealing surface of the other impeller housing closed, without special measures being required.

Sind in entsprechendem Winkelabstand mehrere Dichtflächen gleichmäßig über den Umfang des Laufradgehäuses verteilt angeordnet, so ist einerseits die Reihenschaltung von mehr als zwei verdichtern möglich, andererseits können die Laufradgehäuse der einzelnen Verdichter um ein Vielfaches eines Winkelabstandes gegeneinander verdreht werden. Damit kann bei einem Anschluß der Rohrleitungen an die auf der in Umfangsrichtung des Laufradgehäuses liegende Seite der Anschlußbereiche das Laufradgehäuse in eine dem Richtungsverlauf der anzuschließenden Rohrleitungen entsprechende Lage gedreht werden.Are several sealing surfaces at an appropriate angular distance evenly distributed over the circumference of the impeller housing, on the one hand, the series connection is more than two compressors possible, on the other hand the impeller housing of the individual compressors by a multiple of one Angular distance can be rotated against each other. So that at a connection of the pipes to the in the circumferential direction side of the connection areas lying on the impeller housing the impeller housing in a the direction of the the pipes to be connected are rotated accordingly become.

Dadurch, daß die Einlaß- und die Auslaßöffnungen des Anschlußblockes jeweils von einer Auflagefläche umgeben sind, wird das Anschließen von irgendwelchen Bauteilen, z.B. Rohrleitungen, Filter, Schalldämpfer, Ventilen oder Verschlußdeckeln auf einfache Weise ermöglicht.In that the inlet and outlet openings of the connection block are each surrounded by a support surface, the connection of any components, e.g. Pipelines, Filters, silencers, valves or caps enables in a simple manner.

Bei den Ausführungsbeispielen nach FIG 1 und 2 ist jeweils nur ein Seitenkanalverdichter 2 mit dem Antriebsmotor 1 gekoppelt. An dem aus zwei Gehäusehälften 3 und 4 bestehenden Laufradgehäuse des Seitenkanalverdichters 2 ist ein Anschlußblock 5 vorgesehen, an dem in verschiedenen Richtungen, z.B. auf den beiden Stirnseiten und der Umfangsseite, liegende Ein- und Auslaßöffnungen 6 und 7 vorgesehen sind. An diese Öffnungen 6 und 7 ist jeweils ein Rohrstück 8, welches beispielsweise als Schalldämpfer ausgebildet ist, angeschlossen. Mit den Rohrstücken 8 können dann entsprechende Rohrleitungen verbunden werden.1 with a drive motor is referred to the Flanged the impeller housing of a side channel compressor 2 is. In the embodiments of Figures 1 and 2 is in each case only one side channel compressor 2 with the drive motor 1 coupled. On the two housing halves 3 and 4 The impeller housing of the side channel compressor 2 is a connection block 5 provided on which in different directions, e.g. lying on the two end faces and the peripheral side Inlet and outlet openings 6 and 7 are provided. To this Openings 6 and 7 are each a pipe section 8, which for example is designed as a silencer, connected. Corresponding pipelines can then be used with the pipe sections 8 get connected.

Durch die in verschiedenen Richtungen liegenden Ein- und Auslaßöffnungen 6 und 7 werden für den Anschluß der Rohrleitungen mehr Freiheitsgrade geschaffen. Je nach Verlegungsrichtung der Rohrleitungen, die durch bauliche Gegebenheiten am Aufstellort des Seitenkanalverdichters bestimmt wird, kann die am günstigsten liegende Ein- oder Auslaßöffnung 6 bzw.7 für den Anschluß der Rohrleitung ausgewählt werden. Die nicht benötigten Öffnungen 6 und 7 werden mittels jeweils eines Deckels 9 verschlossen.Through the inlet and outlet openings in different directions 6 and 7 are used for connecting the pipes created more degrees of freedom. Depending on the direction of installation the pipelines, which are due to structural conditions on Location of the side channel blower can be determined the most convenient inlet or outlet opening 6 or 7 be selected for the connection of the pipeline. They don't required openings 6 and 7 are each one Cover 9 closed.

An den Stirnseiten der Gehäusehälften 3 und 4 sind über deren Umfang gleichmäßig verteilt Dichtflächen 10 angeformt. Der Winkelabstand 11 dieser Dichtflächen 10 entspricht sowohl untereinander als auch gegenüber der Ein- bzw. Auslaßöffnung 6 bzw.7 dem Winkelabstand zwischen diesen beiden Öffnungen 6 und 7. Die Dichtflächen 10 entsprechen ferner in ihrer Form und Größe der Form und Größe der Einlaß- bzw. der Auslaßöffnung 6 und 7.At the end faces of the housing halves 3 and 4 are over their Sculpted evenly distributed sealing surfaces 10. Of the Angular distance 11 of these sealing surfaces 10 corresponds to each other as well as opposite the inlet or outlet opening 6 or7 the angular distance between these two openings 6 and 7. The sealing surfaces 10 also correspond in shape and size of the shape and size of the inlet and outlet openings, respectively 6 and 7.

Die FIG 3 und 4 zeigen jeweils zwei strömungsmäßig in Reihe geschaltete Seitenkanalverdichter 12 und 14. Das zu verdichtende Gas wird, wie durch einen Pfeil angedeutet, über ein Rohrstück 8 der am Umfang des Laufradgehäuses liegenden Einlaßöffnung 6 des ersten Seitenkanalverdichters 12 zugeführt. Die weitere auf der äußeren Stirnseite 13 des Laufradgehäuses liegende Einlaßöffnung 6 ist mittels eines Deckels 9 verschlossen. Das Laufradgehäuse des zweiten Seitenkanalverdichters 14 ist derart um einen dem Winkelabstand zwischen der Ein- und Auslaßöffnung 6 und 7 entsprechenden Winkel gegenüber dem Laufradgehäuse des ersten Seitenkanalverdichters 12 verdreht, daß die auf der entsprechenden Stirnseite liegende Einlaßöffnung 6 dieses zweiten Seitenkanalverdichters 14 mit der auf der inneren Stirnseite des Laufradgehäuses des ersten Seitenkanalverdichters 12 liegenden Auslaßöffnung 7 zur Deckung kommt. Die auf der inneren Stirnseite des ersten Seitenkanalverdichters 12 liegende Einlaßöffnung 6 wird durch eine entsprechende Dichtfläche 10 des Laufradgehäuses des zweiten Seitenkanalverdichters 14 und die auf der dem ersten Seitenkanalverdichters 12 zugewandten Stirnseite des zweiten Seitenkanalverdichters 14 liegende Auslaßöffnung durch eine entsprechende Dichtfläche 10 des Laufradgehäuses des ersten Seitenkanalverdichters 12 verschlossen. Damit sind die für die Reihenschaltung notwendigen Strömungsverbindungen durch bloßes Zusammenfügen der beiden Verdichtergehäuse in der entsprechenden Winkelstellung möglich. Die nicht benötigten weiteren Ein- und Auslaßöffnungen 6 und 7 sind mittels entsprechender Deckel 9 verschlossen.FIGS. 3 and 4 each show two flows in series switched side channel compressors 12 and 14. The to be compressed Gas is, as indicated by an arrow, over a Pipe section 8 of the inlet opening lying on the circumference of the impeller housing 6 of the first side channel compressor 12 supplied. The other on the outer end face 13 of the impeller housing lying inlet opening 6 is closed by a cover 9. The impeller housing of the second side channel blower 14 is such an angular distance corresponding between the inlet and outlet opening 6 and 7 Angle to the impeller housing of the first side channel blower 12 twisted that on the corresponding Front end inlet opening 6 of this second side channel compressor 14 with the on the inner face of the Impeller housing of the first side channel compressor 12 lying Outlet opening 7 comes to cover. The one on the inside End face of the first side channel compressor 12 lying inlet opening 6 is by a corresponding sealing surface 10 of the Impeller housing of the second side channel compressor 14 and the on the side compressor 12 facing the first Front side of the second side channel compressor 14 lying Outlet opening through a corresponding sealing surface 10 of the Impeller housing of the first side channel compressor 12 is closed. So that are necessary for the series connection Flow connections by simply joining the two Compressor housing possible in the corresponding angular position. The additional inlet and outlet openings that are not required 6 and 7 are closed by means of corresponding covers 9.

Das direkte Aneinanderkoppeln der entsprechenden Ein- und Auslaßöffnungen 6 und 7 der beiden Laufradgehäuse wird dadurch ermöglicht, daß sich der Anschlußblock 5 jedes Laufradgehäuses hinsichtlich seiner axialen Breite mindestens bis in die beiden Seitenebenen (Trennebenen) des Laufradgehäuses erstreckt. Hierdurch kommen die Anschlußblöcke 5 von zwei zusammenfügbaren Laufradgehäusen unmittelbar in Anlage, so daß unter Zwischenfügung eines Dichtungselementes eine direkte Verbindung der jeweiligen Öffnungen 6 und 7 möglich ist. Die am Laufradgehäuse vorgesehenen Dichtflächen 10 erstrecken sich ebenfalls bis in die Seitenebene des Laufradgehäuses, so daß sie mit dem auf der Stirnseite des Laufradgehäuses liegenden Anlageflächen der Anschlußblöcke 5 fluchten und somit beim Zusammenfügen von zwei Laufradgehäusen ebenfalls direkt die entsprechenden Öffnungen 6 bzw.7 abzudichten vermögen.The direct coupling of the corresponding inputs and Outlet openings 6 and 7 of the two impeller housings is thereby allows the connector block 5 of each impeller housing in terms of its axial width at least up to extends the two side planes (parting planes) of the impeller housing. As a result, the terminal blocks 5 come from two that can be joined together Impeller housings directly in contact, so that with the interposition of a sealing element a direct one Connection of the respective openings 6 and 7 is possible. The extend on the impeller housing provided sealing surfaces 10 itself also in the side plane of the impeller housing, so that they are lying on the front of the impeller housing Contact surfaces of the terminal blocks 5 are aligned and thus when joining two impeller housings also directly the corresponding openings 6 and 7 are able to seal.

Die Darstellungen in FIG 3 und 4 unterscheiden sich lediglich durch eine unterschiedliche Anschlußlage des mit der Auslaßöffnung 7 des zweiten Seitenkanalverdichters 14 verbundenen Rohrstückes 8. Selbstverständlich kann auch das mit der Einlaßöffnung 6 verbundene Rohrstück 8 an die in axialer Richtung liegende Einlaßöffnung 6 des ersten Seitenkanalverdichters 12 angeschlossen werden.The representations in FIGS. 3 and 4 only differ due to a different connection position of the with the outlet opening 7 of the second side channel compressor 14 connected Pipe piece 8. Of course, this can also be done with the inlet opening 6 connected pipe section 8 to the in the axial direction lying inlet opening 6 of the first side channel compressor 12 can be connected.

Die FIG 5 bis 7 zeigen Schaltungsvarianten für einen strömungsmäßig unabhängigen Betrieb mehrerer Seitenkanal verdichter 2. Je nach erforderlicher Anschlußrichtung der mit dem Seitenkanalverdichter 2 zu verbindenden Rohrleitungen werden die entsprechenden Ein- und Auslaßöffnungen 6 und 7 der einzelnen Seitenkanalverdichter 2 belegt.5 to 7 show circuit variants for a flow independent operation of several side channels compressor 2. Depending on the required connection direction with the side channel compressor 2 pipes to be connected the corresponding inlet and outlet openings 6 and 7 of the individual side channel compressors 2 occupied.

Selbstverständlich sind weitere Schaltungsvarianten möglich. So können auch mehr als zwei Seitenkanalverdichter 2 in Reihe geschaltet werden. Hierzu wird der jeweils nächste Seitenkanalverdichter 2 um den entsprechenden Winkel gegenüber dem vorhergehenden Seitenkanalverdichter 2 verdreht an diesem angeschlossen.
Bei einem aus mehr als zwei Verdichtern bestehenden Aggregat kann sowohl eine Reihenschaltung von Verdichtern als auch gleichzeitig ein unabhängiger oder paralleler Betrieb der übrigen Verdichter vorgesehen werden. Insbesondere die am Umfang der Laufradgehäuse vorgesehenen Ein- und Auslaßöffnungen 6 und 7 ermöglichen bei aus mehr als zwei Seitenkanalverdichtern bestehenden Aggregaten einen strömungsmäßig unabhängigen Betrieb der einzelnen Verdichter untereinander. Da die Ein- und Auslaßöffnungen unabhängig voneinander zugänglich sind.
Of course, other circuit variants are possible. In this way, more than two side channel compressors 2 can also be connected in series. For this purpose, the next side channel compressor 2 is connected to the previous side channel compressor 2 rotated by the corresponding angle.
In the case of an assembly consisting of more than two compressors, both a series connection of compressors and, at the same time, independent or parallel operation of the other compressors can be provided. In particular, the inlet and outlet openings 6 and 7 provided on the circumference of the impeller housing enable the individual compressors to operate in a flow-independent manner in units consisting of more than two side channel compressors. Because the inlet and outlet openings are independently accessible.
