Abstract

Screw compressor in compact arrangement in which screw block and motor are connected together in a supporting fashion on approximately the same axis by means of the housing of a radial fan lying between them. The housing of the radial fan of spiral construction and provided with an outlet connection can at the same time be assembled rotated in relation to the compressor block or motor by any angle up to 360 DEG . In addition a flat cooler is arranged on the outlet connection of the fan as oil cooler and recooler for the compressed air.

Description

Schrauberko mp r essor in kompakter AnordnungScrewdriver body in a compact arrangement

Die Erfindung bezieht sich auf einen Schraubenkompressor in kompakter Anordnung gemäß Oberbegriff des Patentanspruches. Derartige Cchraubenkompressoren sind bekannt.The invention relates to a screw compressor in a more compact Arrangement according to the preamble of claim. Such screw compressors are known.

Sie bieten den Vorteil einer guten Raumnutzung bei beliebiger Kühlluftführung.They offer the advantage of a good use of space with any cooling air flow.

Aufgabe der Erfindung ist es, die genannten Kompressoren insbesondere bezüglich des Kühlsystems noch weiter zu verbessern, wobei sowohl eine bessere Ausnützung der Kühlung wie auch die Möglichkeit einer variablen Kühlluftführung angestrebt wird. Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruches angegebenen Mittel gelöst.The object of the invention is to provide the compressors mentioned in particular to improve even further with regard to the cooling system, with both a better utilization the cooling as well as the possibility of a variable cooling air flow aimed at will. According to the invention, this object is achieved by the characterizing features of the patent claim specified means resolved.

Die mit der Erfindung erzielten Vorteile sind wie folgt: Es wird eine effektivere Kühlung durch Anwendung eines herkömmlichen Flachkühlers bei größerem Kühlluftdurchsatz erreicht. Insbesondere dadurch, daß der Flachkühler direkt am Austrittsstutzen des Radiallüfters sitzen kann, erfolgt eine optimale Ausnützung der Kühlluft. Hierdurch wird der Kompressor insbesondere auch für einen großen Drehzahlbereich einsetzbar. Die Kühlluftführung kann unter Verwendung der gleichen Grundelemente praktisch allen beliebigen Einbauverhältnissen, und zwar unabhängig davon, ob es sich um stationäre oder fahrbare Kompressoren handelt, angepaßt und optimal gestaltet werden.The advantages achieved with the invention are as follows: There is a more effective cooling by using a conventional flat cooler for larger ones Cooling air throughput reached. In particular, the fact that the flat cooler directly on If the outlet nozzle of the radial fan can be seated, optimum use takes place the cooling air. As a result, the compressor is also particularly suitable for a large speed range applicable. The cooling air duct can be made using the same basic elements practically any installation conditions, regardless of whether there is stationary or mobile compressors, adapted and optimally designed will.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachstehend näher beschrieben. Es zeigen Fig. 1 die Vorderansicht, Fig. 2 die Draufsicht und Fig. 3 den Schnitt A - B gemäß Fig. 1.An embodiment of the invention is shown in the drawing and is described in more detail below. It Fig. 1 shows the front view, FIG. 2 the top view and FIG. 3 the section A - B according to FIG. 1.

Wie aus den Figuren ersichtlich, besteht der Kompressor @m wesentlichen aus einem Verdichterblock 1 mit Ölabscheider 2, Ansaugfilter 3 und ölfilter 4, aus einem Radiallüfter 5 mit spiralförmigem Gehäuse 6 und mit einem am Austrittsstutzen 7 des Gehäuses 6 sitzenden Flachkühler 8 sowie aus einem Elektromotor 9. Hierbei sind der Verdichterblock 1, das Gehäuse 6 des Radiallüfters 5 sowie der Elektromotor 9 etwa gleichachsig zueinander und tragend miteinander verbunden. Wie insbesondere aus Figur 3 hervorgeht, ist das über eine Lielzahl von Bohrungen 10 mit dem rlansch des Motors verbundene Gehäuse 6 des Radiallüfters 5 gegenüber dem Motor 9 und auch gegenüber dem Verdichterblock 1 beliebig um bis 360° verdreht montierbar. Die Verbindung zwischen Gehäuse 6 und Verdichterblock 1 ist hierbei analog der Verbindung zwischen Gehäuse 6 und Motor 9 ausgeführt. Das Verdrehen des Gehäuses 6 kann in einzelnen Schritten, die dem Abstand der Bohrungen 10 entsprechen, erfolgen, so daß der Flachkühler 8 beliebig viele Stellungen einnehmen kann. In Figur 3 wurde die Stellung des Flachkühlers 8' parallel zur Grundfläche strichpunktiert eingezeichnet. Es ist ohne weiteres klar, daß der Flachkühler 8 auch auf der rechten Seite oder aber oben oder aber auch in beliebigen Zwischenstellungen sitzen könnte. Selbst ein stufenloses Verstellen des Gehäuses 6 des Radiallüfters 5 wäre ohne wtit tirt". möglich, wenn die Rohrungen 10 z.B. als Langlöcher ausgeführt würden.As can be seen from the figures, the compressor @m consists essentially from a compressor block 1 with oil separator 2, suction filter 3 and oil filter 4 a radial fan 5 with a spiral housing 6 and with one on the outlet nozzle 7 of the housing 6 seated flat cooler 8 and an electric motor 9. Here are the compressor block 1, the housing 6 of the radial fan 5 and the electric motor 9 approximately coaxial to one another and connected to one another in a load-bearing manner. How in particular As can be seen from FIG. 3, this is via a number of holes 10 with the flange of the motor connected housing 6 of the radial fan 5 opposite the motor 9 and also Can be mounted rotated by up to 360 ° in relation to the compressor block 1. The connection between housing 6 and compressor block 1 is analogous to the connection between Housing 6 and motor 9 executed. The rotation of the housing 6 can in individual Steps that correspond to the distance between the bores 10, so that the flat cooler 8 can assume any number of positions. In Figure 3, the position of the flat cooler 8 'drawn in dash-dotted lines parallel to the base. It is straightforward it is clear that the flat cooler 8 is also on the right-hand side or above or else could also sit in any intermediate positions. Even a stepless adjustment of the housing 6 of the radial fan 5 would be possible without wtit if the pipes 10, for example, would be designed as elongated holes.

Die Kühlluft führung bei der Kompressoranordnung ist durch Pfeile markiert. [)ip Kühlluft tritt - arn Motor vorbeigeführt - radial in das Gehäuse 6 ein, verteilt sich über den Austrittsstut@en 7 auf den Flachkühler 8, der im einzelnen aus einem Ölkühler 81 aund einem Nachkühler 82 für die Druckluft besteht.The cooling air management in the compressor arrangement is through Arrows marked. [) ip cooling air enters the housing radially - passed by the motor 6 a, is distributed over the Ausittsstut @ en 7 on the flat cooler 8, which in detail consists of an oil cooler 81 and an aftercooler 82 for the compressed air.
