Description

Die Erfindung betrifft ein Flüssigkeitsringverdichter- oder vakuumpumpen-Aggregat nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a liquid ring compressor or vacuum pump unit according to the preamble of claim 1.

Ein Aggregat der genannten Art ist aus der DE-B-27 31 451 bekannt, bei dem die einzelnen Komponenten in miteinander unmittelbar aneinandergrenzenden Gehäusen angeordnet sind und von aussen nur insgesamt vier Leitungen für Gas- und Betriebsflüssigkeit angeschlossen werden müssen.An assembly of the type mentioned is known from DE-B-27 31 451, in which the individual components are arranged in housings which are directly adjacent to one another and only a total of four lines for gas and operating fluid have to be connected from the outside.

Bei der bekannten Anordnung ist der Flüssigkeitsabscheider Teil eines als Motorgehäuse ausgebildeten Verteilers für Gas und Betriebsflüssigkeit und daher in seiner Grösse und räumlichen Zuordnung zum Schaufelrad festgelegt und ausserdem sind die Anschlüsse für Gas und Betriebsflüssigkeit am Verteiler konzentriert, so dass sich gewisse Aufstellungs- und Montageschwierigkeiten bei Verlegung der äusseren Rohrleitungen und wegen der Erstreckung aller Teile in Richtung der Motorwelle ergeben können. Ausserdem ist die Grösse und Gestalt des Flüssigkeitsabscheiders relativ klein bemessen, so dass er als Vorratsbehälter und zur Aufnahme eines Wärmetauschers nicht geeignet ist, was für Anwendungen mit Kreisschaltung der Betriebsflüssigkeit notwendig wäre.In the known arrangement, the liquid separator is part of a distributor for gas and operating liquid designed as a motor housing and therefore in terms of its size and spatial allocation to the paddle wheel, and the connections for gas and operating liquid are also concentrated on the distributor, so that certain installation and assembly difficulties arise Laying of the outer pipelines and due to the extension of all parts in the direction of the motor shaft. In addition, the size and shape of the liquid separator is relatively small, so that it is not suitable as a storage container and for holding a heat exchanger, which would be necessary for applications with a circuit of the operating liquid.

Der Erfindung liegt die Aufgabe zugrunde, ein Aggregat der eingangs genannten Art zu schaffen, bei dem ein in seiner Grösse nicht durch Konstruktionsmerkmale des Verteilers beeinflusster und in seiner Grösse beschränkter Abscheide-, Kühl- und Vorratsbehälter austauschbar ist, bei dem unter Fortfall eines mit dem Motorgehäuse einstückigen Verteilers die Anschlussmöglichkeiten für Gas und Betriebsflüssigkeit variierbar sind und die Länge des Aggregats in Richtung der Motorwelle allein durch das Gehäuse für den Verdichter bzw. die Vakuumpumpe und die Motorgrösse bestimmt werden kann und bei dem eine Kreisschaltung der Betriebsflüssigkeit möglich ist.The invention has for its object to provide an assembly of the type mentioned, in which a size not influenced by the design features of the distributor and limited in size separating, cooling and storage container is interchangeable, in which one with the Motor housing one-piece distributor, the connection options for gas and operating fluid are variable and the length of the unit in the direction of the motor shaft can be determined solely by the housing for the compressor or the vacuum pump and the motor size and in which a circuit of the operating fluid is possible.

Die Lösung der gestellten Aufgabe gelingt durch die kennzeichnenden Merkmale des Patentanspruchs 1.The problem is solved by the characterizing features of claim 1.

Eine besonders kompakte Ausgestaltung der Erfindung ist Gegenstand des Patenanspruchs 2, die als ein Ausführungsbeispiel in der Zeichnung dargestellt und nachfolgend erläutert ist. Es zeigen

  • Fig. 1 ein Verbindungsschema der Teile des Gegenstandes der Erfindung,
  • Fig. 2 den Gegenstand der Fig. 1 in perspektivisch vereinfachter Darstellung.
A particularly compact embodiment of the invention is the subject of patent claim 2, which is shown as an embodiment in the drawing and explained below. Show it
  • 1 is a connection diagram of the parts of the subject of the invention,
  • Fig. 2 shows the subject of Fig. 1 in a perspective simplified representation.

Die beiden quaderförmigen Gehäuseblöcke I und 11 weisen auf den einander zugewandten ebenen Aussenseiten la und lIa jeweils sich deckende Verbindungsöffnungen 1, 2 und 3 auf, die durch ein Verbindungsteil KT nach aussen abgedichtet und mit durch Innenwände begrenzten Kanälen A', B', C' im Gehäuseblock I bzw. A", B", C" im Gehäuseblock 11 in Verbindung stehen. Der Kanal A' ist mit der Saugseite und der Verbindungsöffnung 1, der Kanal B' mit der Druckseite des Flüssigkeitsringverdichters bzw. der -vakuumpumpe P und der Verbindungsöffnung 2, der Kanal C' mit der Verbindungsöffnung 3, einem Wärmetauscher WT1 für den Elektromotor M sowie dem Flüssigkeitsabfluss KWA im Gehäuseblock I verbunden. Der Kanal A" ist mit der Verbindungsöffnung 1 und über einen Wärmetauscher WT2 für die Betriebsflüssigkeit mit dem Abluss des Flüssigkeitsabscheiders A, der Kanal B" mit der Verbindungsöffnung 2 und dem Einlass des Flüssigkeitsabscheiders sowie der Kanal C" mit dem Flüssigkeitszufluss KWE, dem Wärmetauscher WT2 für die Betriebsflüssigkeit und der Verbindungsöffnung 3 im Gehäuseblock 11 verbunden. Die Kanäle A', A" und B', B" schliessen den gestrichelt gezeichneten Betriebsflüssigkeitskreislauf BF. Ausserdem ist der Verdichter bzw. die Vakuumpumpe P saugseitig mit einem Gaseinlass GE im Gehäuseblock I, der Auslass des Flüssigkeitsabscheiders A mit dem Gasauslass GA im Gehäuseblock II verbunden.The two parallelepiped-shaped housing blocks I and 11 each have overlapping connecting openings 1, 2 and 3 on the flat outer sides la and lIa facing one another, which are sealed to the outside by a connecting part KT and with channels A ', B', C 'delimited by inner walls. in the housing block I or A ", B", C "in the housing block 11. The channel A 'is with the suction side and the connection opening 1, the channel B' with the pressure side of the liquid ring compressor or vacuum pump P and the Connection opening 2, the channel C 'with the connection opening 3, a heat exchanger WT1 for the electric motor M and the liquid drain KWA in the housing block I. The channel A "is connected to the connection opening 1 and via a heat exchanger WT2 for the operating liquid with the outlet of the liquid separator A, the channel B "with the connection opening 2 and the inlet of the liquid separator and the channel C" with the liquid inflow KWE, the Wärmeta uscher WT2 for the operating fluid and the connection opening 3 in the housing block 11 connected. Channels A ', A "and B', B" close the operating fluid circuit BF shown in dashed lines. In addition, the compressor or the vacuum pump P is connected on the suction side to a gas inlet GE in the housing block I, the outlet of the liquid separator A to the gas outlet GA in the housing block II.

Der Flüssigkeitszufluss KWE ist an der Stirnseite und der Gasauslass GA an der Oberseite des Gehäuseblocks 11, der Flüssigkeitsabfluss KWA an der Seitenwand und der Gaseinlass GE an der Oberseite des Gehäuseblocks 1 angebracht, so dass sich die äusseren Zu- und Ableitungen für Gas und Kühlflüssigkeit nicht im Wege stehen und sich die Baulänge des Aggregats lediglich durch den Flüssigkeitsabscheider samt Wärmetauscher im Gehäuseblock 11 und durch die Pumpe bzw. den Vakuumverdichter P sowie den Elektromotor M samt Wärmetauscher WT1 im Gehäuseblock 1 bestimmt. Die Auslegung des Abscheide- und Vorratsraumes A sowie des Wärmetauschers WT2 kann unabhängig von den räumlichen Gegebenheiten des Gehäuseblockes 1 erfolgen. Die ebenen fluchtenden Unterseiten beider Gehäuseblöcke lassen eine einfache und sichere Montage auf einer gemeinsamen Unterlage zu.The liquid inflow KWE is attached to the front side and the gas outlet GA to the top of the housing block 11, the liquid outflow KWA to the side wall and the gas inlet GE to the top of the housing block 1, so that the external inlets and outlets for gas and coolant are not stand in the way and the overall length of the unit is determined only by the liquid separator together with the heat exchanger in the housing block 11 and by the pump or the vacuum compressor P and the electric motor M together with the heat exchanger WT1 in the housing block 1. The separation and storage space A and the heat exchanger WT2 can be designed independently of the spatial conditions of the housing block 1. The flat, aligned undersides of both housing blocks allow simple and safe installation on a common surface.
