Patentiert Im Deutschen Reiche vom 16. Februar 1910 ab.Patented in the German Empire on February 16, 1910.
Kreiselverdichter, -pumpen u. dgl. Haben bekanntlich "die Eigenschaft, bei gleichbleibender Geschwindigkeit stets auf annähernd gleichen Druck zu fördern, während die Menge dieses geförderten Mittels sich je nach der Belastung ändert. Nun ist es aber unter Umständen vorteilhaft, die Menge des geförderten Mittels bei veränderlichem Drucke annähernd gleichbleibend zu halten.Centrifugal compressors, pumps and the like are known to have "the property of constant Always promote speed at approximately the same pressure while the crowd this funded agent changes depending on the load. Now it may be advantageous to approximate the amount of the conveyed agent at varying pressures to keep constant.
Diese Aufgabe wird durch vorliegende Erfindung in einfacher Weise dadurch gelöst, daß man in die Hauptleitung ein Drosselorgan einschaltet, welches durch seine jeweilige, vom Druckunterschiede in der Leitung abhängige Lage ein mit ihm verbundenes Regelorgan des Antriebsmotors beeinflußt. Die Regelung der Geschwindigkeit des Antriebsmotors muß derart erfolgen, daß bei abnehmender Drosselung infolge abnehmenden DruckunterschiedesThis object is achieved by the present invention in a simple manner in that that one turns on a throttle device in the main line, which by its respective, from Pressure differences in the line dependent position a control element connected to it of the drive motor influenced. The regulation of the speed of the drive motor must take place in such a way that with decreasing throttling due to decreasing pressure difference
der Antriebsmotor langsamer läuft und umgekehrt, bis wieder' Gleichgewicht bezüglich des Drosselorgans hergestellt ist.the drive motor runs slower and vice versa until 'equilibrium' again of the throttle organ is made.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht. Fig. 1 ist eine Seitenansicht des Erfindungsgegenstandes, teilweise im Schnitt. Fig. 2 zeigt die Verbindung des Drosselorgans mit dem Gestänge des Maschinenreglers. Fig. 3 zeigt das Schaltungsschema der Regelungseinrichtung. An embodiment of the invention is illustrated in the drawing. Fig. 1 is a side view of the subject matter of the invention, partly in section. Fig. 2 shows the connection of the throttle device with the linkage of the machine controller. 3 shows the circuit diagram of the control device.

selverdichter b fördert das verdichtete Mittel durch die Rohrleitung c, welche durch ein je nach dem Druckunterschied in der Leitung sich einstellendes Organ d mehr oder minder gedrosselt wird. Dieses Organ d überträgt seine Bewegungen durch das Gestänge e auf den Schalthebel eines in den Stromkreis eines , Elektromotors eingeschalteten Regelungswiderstandes derart, daß bei Verminderung der Drosselung der Motor langsamer läuft und umgekehrt. Der Widerstand des Drosselorgans kann durch ein verschiebbares Gewicht g, Feder o. dgl. dem jeweiligen Zwecke entsprechend eingestellt werden.Self-compressor b conveys the compressed medium through the pipeline c, which is more or less throttled by an organ d which is established depending on the pressure difference in the line. This organ d transmits its movements through the linkage e to the shift lever of a control resistor connected to the circuit of an electric motor in such a way that when the throttling is reduced, the motor runs more slowly and vice versa. The resistance of the throttle element can be adjusted according to the respective purpose by means of a displaceable weight g, a spring or the like.
Das Drosselorgan kann naturgemäß auch in die Saugleitung eingebaut werden. Der Einbau in die Druckleitung hat jedoch den Vorteil, daß das Drosselorgan zugleich als Rückschlagklappe, die an sich stets notwendig ist, ausgebildet werden kann.The throttle element can naturally also be built into the suction line. Of the Installation in the pressure line, however, has the advantage that the throttle element also acts as a Non-return valve, which is always necessary in itself, can be formed.
Die Wirkungsweise der Vorrichtung ist nun folgende:The mode of operation of the device is now as follows:
Nimmt die Menge des vom Kreiselverdichter geförderten Mittels ab infolge stärkerer, durch zunehmenden Gegendruck hervorgerufener Drosselung, so wird durch Vermittlung des Gestänges e der Schalthebel f emporgehoben, und es wird mehr Widerstand in den Magnetstromkreis des .Nebenschlußmotors eingeschaltet, so daß letzterer sich schneller dreht, um If the amount of the medium conveyed by the centrifugal compressor decreases as a result of stronger throttling caused by increasing counter pressure, the switching lever f is raised by means of the linkage e , and more resistance is switched on in the magnetic circuit of the .shunt motor, so that the latter rotates faster, around

wieder Gleichgewicht bezüglich des Druckunterschiedes herzustellen. Nimmt im Gegenteil die Menge des geförderten Mittels infolge geringen Gegendruckes zu, so wird durch die sich öffnende Klappe durch Vermittlung des Gestänges e und des Schalthebels f der Elektromotor auf geringere Umlauf zahl geregelt, wodurch die Leistung der Pumpe bis zu einem neuen Ausgleich verringert wird. Es ist natürlieh selbstverständlich, daß in gewissen Fällen das Regelorgan zugleich als Meßorgan verwendet werden kann. re-establish equilibrium with respect to the pressure difference. If, on the contrary, the amount of the funded medium increases as a result of low back pressure, the electric motor is regulated to a lower number of revolutions through the opening flap through the intermediary of the linkage e and the shift lever f , whereby the performance of the pump is reduced until a new balance is reached. It goes without saying that in certain cases the regulating organ can also be used as a measuring organ.
