Abstract
Die Erfindung betrifft einen Flüssigkeitsringverdichter oder -vakuumpumpe mit flüssigkeitsgekühltem Elektromotor und einem Flüssigkeitsabscheider in rohrleitungsfrei miteinander verbundenen, durch Innenwände in Kammern unterteilten Gehäusen. Das Verdichter- bzw. Pumpengehäuse bildet mit dem Motorgehäuse einen ersten Gehäuseblock 1. In einem mit diesen über innere Kanäle (A', A", B', B", C', C") verbundenen Gehäuseblock II ist ein Wärmetauscher und der Flüssigkeitsabscheider angeordnet. Die beiden quaderförmigen Gehäuseblöcke I und II liegen an einer Seite unmittelbar abgedichtet aneinander. Die Ein- und Auslässe für die Förderflüssigkeit und die Kühlflüssigkeit sind auf beide Gehäuseblöcke verteilt. Der Gegenstand der Ertindung wird bei Pumpen oder Verdichtern mit Kreisschaltung der Betriebsflüssigkeit ohne äussere laufende Zufuhr von Kühlflüssigkeit angewendet.The invention relates to a liquid ring compressor or vacuum pump with a liquid-cooled electric motor and a liquid separator in housings which are connected to one another without pipelines and are divided by inner walls into chambers. The compressor or pump housing forms a first housing block 1 with the motor housing. In a housing block II connected to them via inner channels (A ', A ", B', B", C ', C ") there is a heat exchanger and the liquid separator The two parallelepiped-shaped housing blocks I and II are directly sealed to one another. The inlets and outlets for the conveying liquid and the cooling liquid are distributed between the two housing blocks Coolant supply applied.
Description
Die Erfindung betrifft Flüssigkeitsringverdichter oder -vakuumpumpen nach dem Oberbegriff des Patentanspruchs 1. Ein Aggregat der genannten Art ist aus der DE-AS 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.The invention relates to liquid ring compressors or vacuum pumps according to the preamble of
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 designed as a motor housing for gas and operating fluid and therefore in terms of its size and spatial assignment to the impeller, and the connections for gas and operating fluid are concentrated on the distributor, so that certain installation and assembly difficulties are encountered 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 dimensioned relatively small, so that it is not suitable as a storage container and for receiving 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 can be varied 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 beiden quaderförmigen Gehäuseblöcke I und II weisen auf den einander zugewandten ebenen Außenseiten Ia und IIa 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 II in Verbindung stehen. Der Kanal A' ist mit der Saugseite und der Verbindungsöffnung 1, der Kanal B' mit der Druckseite des Flüssigkeitsringver-, dichters 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 Abfluß 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 2 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 II each have connecting
Der Flüssigkeitszufluß KWE ist an der Stirnseite und der Gasauslaß GA an der Oberseite des Gehäuseblocks II, der Flüssigkeitsabfluß KWA an der Seitenwand und der Gaseinlaß GE an der Oberseite des Gehäuseblocks I 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 II und durch die Pumpe bzw. den Vakuumverdichter P sowie den Elektromotor M samt Wärmetauscher WT1 im Gehäuseblock I bestimmt. Die Auslegung des Abscheide- und Vorratsraumes A-sowie des Wärmetauschers WT2 kann unabhängig von den räumlichen Gegebenheiten des Gehäuseblockes I 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 II, the liquid outflow KWA to the side wall and the gas inlet GE to the top of the housing block I, 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 II and by the pump or the vacuum compressor P and the electric motor M together with the heat exchanger WT1 in the housing block I. The design of the separation and storage space A and the heat exchanger WT2 can be independent take place from the spatial conditions of the housing block I. The flat, aligned undersides of both housing blocks allow simple and safe installation on a common surface.
