Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei der Parallelschaltung von Verdichtern brachte man die Regelungsorgane der einzelnen Verdichter in unmittelbare automatische Abhängigkeit von dem Drucke in dem gemeinsamen Rohrnetz. Diese Anordnung hatte jedoch den Nachteil, daß sich die Leistungen binnen kurzer Zeit ganz verschieden auf die einzelnen Verdichter verteilten, da sich die Druckregler niemals mit genau gleicher Empfindlichkeit herstellen lassen; insbesondere werden bei solchen verschiedenen Fabrikats die Druckschwankungen in dem Rohrnetz in einem ungleichen Verhältnis auf die Leistungsregler der einzelnen Verdichter übertragen.When compressors were connected in parallel, the regulating organs of the individual were brought in Compressor in direct automatic dependence on the pressures in the common Pipe network. However, this arrangement had the disadvantage that the services within a short time were very different on the individual compressors, since the pressure regulators never have exactly the same sensitivity have made; in particular, with such different make, the Pressure fluctuations in the pipe network in an unequal relationship to the power regulator of the individual compressors.

Dieser Übelstand wird nun durch vorliegende Erfindung dadurch vermieden, daß eine gemeinsame Antriebsvorrichtung für die Leistungsregelungsorgane sämtlicher parallel arbeitender Verdichter vorgesehen ist, welche entweder selbsttätig abhängig von dem Druck im Rohrnetz ist oder mittels Hand bewegt wird. Um nun zwecks Ausgleichs der etwa auftretenden verschiedenen Belastungen der Verdichter deren Regelungsorgane zueinander verstellen zu können, sind letztere abschaltbar mit dem gemeinsamen Antriebsorgan verbunden.This drawback is now avoided by the present invention in that a common Drive device for the power control organs all working in parallel Compressor is provided, which either automatically depends on the pressure in the pipe network is or is moved by hand. In order to compensate for any occurring to be able to adjust their regulating organs to each other at various loads on the compressors, the latter are connected to the common drive element so that they can be switched off.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung veranschaulicht. An exemplary embodiment of the subject matter of the invention is illustrated in the drawing.

Die als Drosselventile ausgebildeten Regulierorgane α einer Anzahl parallel geschalteter Verdichter b werden von einer gemeinsamen Steuerwelle c angetrieben, deren Verstellung, wie bereits erwähnt, entweder von Hand oder durch einen Regler erfolgen kann. Jedes einzelne Drosselorgan ist durch eine Kupplung d abschaltbar mit der gemeinsamen Steuerwelle c verbunden und kann nach vorgenommener Entkupplung mittels Handrad e beliebig zu den Drosselventilen der übrigen parallel geschalteten Verdichter verstellt werden, so daß man es vollkommen in der Hand hat, die Belastung auf die verschiedenen, auf ein gemeinsames Sammelrohr arbeitenden Verdichter zu verteilen. In das Druckrohr des Verdichters b ist ein Abblaseventil f eingebaut, welches bei einem gewissen Grade der Drosselung durch einen auf dem die Bewegungen der Steuerwelle auf das Drosselventil α übertragenden Gestänge g vorgesehenen Anschlag h geöffnet wird, um die bei Unterschreitung der geringsten zulässigen Leistung im Verdichter auftretenden Stöße zu vermeiden. The regulating elements α, designed as throttle valves, of a number of compressors b connected in parallel are driven by a common control shaft c, which, as already mentioned, can be adjusted either by hand or by a controller. Each individual throttle element is connected to the common control shaft c by a clutch d which can be switched off and, after decoupling has been carried out, by means of handwheel e it can be adjusted as required to the throttle valves of the other compressors connected in parallel, so that you have it completely in your hand, the load on the various to distribute the compressor working on a common manifold. A blow-off valve f is built into the pressure pipe of the compressor b , which is opened at a certain degree of throttling by a stop h provided on the linkage g that transmits the movements of the control shaft to the throttle valve α , in order to prevent the compressor from dropping below the lowest permissible power to avoid any impacts.
