Description

Einrichtung zum Fördern von Flüssigkeiten oder Gasen durch parallel geschaltete Leitungen. Sollen Flüssigkeiten oder Gase durch parall-el geschaltete Rohrleitungen gefördert werden, so ist es vielfach erforderlich,. daß dauernd jedes Rohr von derselben Menge durchströmt wird wie die anderen Rohre. Diese Aufgabe liegt vor allen Dingen bei Röhrenkesseln vor, bei denen eine ungleichmäßige Förderung in den einzelnen Rohr-en Störungen der Dampferzeugung und unter Umständen schwere Beschädigungen der Kesselanlage zur- Folge haben würde.. Diese Schwierigkeiten sollen durch die vorliegende Erfindung beseitigt werden. -- -Sie besteht darin, daß vor jede Leitung. eine umlaufende, durch das zu fördernde Mittel in Drehung versetzte Verdränigerpumpe geschaltet ist, wobei aber sämtliche Pumpen fest auf der gleichen, drehbar gelagerten Welle sitzen.Device for conveying liquids or gases through lines connected in parallel. If liquids or gases are to be conveyed through pipelines connected in parallel, it is often necessary. that the same amount flows through each pipe as the other pipes. This task is primarily concerned with tubular boilers in which an uneven delivery in the individual tubes would lead to disturbances in the generation of steam and, under certain circumstances, serious damage to the boiler system. These difficulties are intended to be eliminated by the present invention. - - It consists in the fact that before each line. a rotating displacement pump set in rotation by the means to be conveyed is connected, but all pumps are firmly seated on the same rotatably mounted shaft.

In der Abbildung ist schematisch eine derartige Einrichtung dargestellt. Das zu fördernde Mittel tritt in das Rohr i ein und wird in die Rohre 2, 3 und 4 geleitet. Uni eine stets gleiche Förderung in den einzelnen Rohren zu erzielen, ist vor jede Leitung eine umlaufende Verdrängerpumpe 5, 6, 7 geschaltet, welche von dem zu fördernden Mittel in Drehung versetzt wird. D#e ausgleichende Wirkung der neuen Einrichtung kommt folgendermaßen zustande - In der Leitung 2 trete beispielsweise ein größerer Widerstand auf als in den Leitungen 3 und 4. Infolgedessen wird der Druck im Rohre i ansteigen. Da aber dann zwischen Pumpe 6 und Leitung 3 sowie zwischen Pumpe 7 und Leitung 4 eine Druckdifferenz entsteht, so wirken die Pumpen 6 und 7 als Motor und treiben also die Pumpe 5 an, so daß, diese die gleiche Flüssigkeitsmenge durch die Leitung 2 drückt, wie durch die Leitungen 3 und 4 strömt. Es wird also auf alle Fälle erreicht, daß gleiche Fördermengen durch alle Leitungen hindurchfließen.Such a device is shown schematically in the figure. The medium to be conveyed enters pipe i and is directed into pipes 2, 3 and 4. In order to always achieve the same conveyance in the individual tubes, a circulating displacement pump 5, 6, 7 is connected in front of each line, which is set in rotation by the means to be conveyed. The compensating effect of the new device comes about as follows - in line 2, for example, a greater resistance occurs than in lines 3 and 4. As a result, the pressure in pipe i will rise. But since a pressure difference then arises between pump 6 and line 3 and between pump 7 and line 4, pumps 6 and 7 act as a motor and thus drive pump 5 , so that it presses the same amount of liquid through line 2, as flows through lines 3 and 4. It is thus achieved in all cases that the same delivery rates flow through all lines.

Als Verdrängerpumpen können beliebige Systeme verwendet werden, entweder solche mit exzentrischem Gehäuse und radial beweglichen Schiebern im umlaufenden Teil, Kapselpumpen, Zahnradpumpen und ähnliche.Any systems can be used as positive displacement pumps, either those with an eccentric housing and radially movable slides in the rotating Part, capsule pumps, gear pumps and the like.
