Description
Fördereinrichtung für Flüssigkeiten Man kennt Fördereinrichtungen- für Flüssigkeiten, die aus einem umlaufenden glatten, zylindrischenKörper und einem die Mantelfläche dieses Körpers umschließenden Gehäuse bestehen, an dessen Innenfläche Aussparungen vorgesehen sind. Es sind Aussparungen bekannt, die sich in Richtung des Flüssigkeitsstromes und auch in axialerRichtung verengen.Conveying device for liquids One knows conveying devices- for liquids, which consist of a smooth, cylindrical body and a the outer surface of this body enclosing housing exist on its inner surface Recesses are provided. There are known recesses that are in the direction of the liquid flow and also in the axial direction.
Die Erfindung bringt eine weitere Ausgestaltung derartiger Fördereinrichtungen dadurch, daß die sich in der Drehrichtung und in axialer Richtung verjüngenden Aussparungen stufenförmige Absätze aufweisen. Dadurch wird der Rückfluß verhindert und eine erhöhte Druckwirkung erreicht, somit die Brauchbarkeit des Gerätes wesentlich gefördert.The invention brings a further embodiment of such conveying devices in that the recesses tapering in the direction of rotation and in the axial direction have step-shaped paragraphs. This prevents reflux and increases it Pressure effect achieved, thus the usability of the device significantly promoted.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt, und zwar zeigt: Abb. i einen Querschnitt durch die Fördereinrichtung hei einer mehrstufigen Ausführungsform.In the drawing, two exemplary embodiments of the invention are shown, namely shows: Fig. i a cross-section through the conveying device at a multi-stage Embodiment.
Abb. z eine Abwicklung des entsprechenden Gehäuseteils, Abb.3 einen Querschnitt durch eine einstufige Bauart und Abb. d. eine Abwicklung des entsprechenden Gehäuseteils zu Abb. 3.Fig. Z a development of the corresponding housing part, Fig.3 a Cross-section through a single-stage design and Fig. D. a settlement of the corresponding Housing part to Fig. 3.
Wie aus den Abbildungen ersichtlich ist, tritt die zu fördernde Flüssigkeit in radialer Richtung bei a in das Gehäuse ein und wird durch denumlaufenden glattenZylinderb mitgenommen. Wie die Zeichnungen erkennen lassen, verjüngen sich die Aussparungen c nicht nur in radialer Richtung, sondern auch in axialer Richtung, so daß für den Flüssigkeitsstrom ein ständig kleiner werdender Raum zur Verfügung steht. Dadurch wird die Strömungsgeschwindigkeit bzw. der Druck der Flüssigkeit zunehmend größer.As can be seen from the figures, the liquid to be pumped occurs in the radial direction at a into the housing and is driven by the rotating smooth cylinder b taken away. As the drawings show, the recesses are tapered c not only in the radial direction, but also in the axial direction, so that for the Liquid flow a constantly decreasing space is available. Through this the flow velocity or the pressure of the liquid becomes increasingly greater.
Um nun den Rückfluß entgegen der Drehrichtung des zylindrischen Körpers b geringer zu halten, sind, wie Abb. i erkennen läßt, stufenförmige Absätze vorgesehen, die den Rückstrom drosseln und die Flüssigkeit vor den Stufen an den umlaufenden Körper heranbringen. Man erhält so einen guten Wirkungsgrad und eine sehr erhebliche Förderleistung.To now the backflow against the direction of rotation of the cylindrical body b is to be kept lower, as Fig. i shows, step-shaped shoulders are provided, which throttle the return flow and the liquid in front of the stages to the circulating Bring the body. This gives a good level of efficiency and a very substantial one Delivery rate.
Man kann mehrere dieser Einrichtungen neben- oder hintereinander anordnen, wobei insbesondere ein weiterer Vorteil dadurch entsteht, daß durch die axiale Verengung der Aussparungen die seitliche tlerdeckung mit zunehmendem Druck breiter wird, so daß auch die seitliche Abströmung gering gehalten ist.You can arrange several of these devices next to one another or one behind the other, a further advantage in particular arises from the fact that the axial constriction of the recesses, the lateral cover becomes wider with increasing pressure, so that the lateral outflow is also kept low.
Die Vorrichtung eignet sich zum Fördern von Flüssigkeiten aller Art, insbesondere von Ölen oder anderen viscosen Flüssigkeiten. Aber auch die Förderung von wäßrigen Flüssigkeiten und von Gasen ist möglich, wenn man. die Aussparungen und die Zwischenräume zwischen dem zylindrischen Körper und dem Gehäuse entsprechend eng hält.The device is suitable for pumping liquids of all kinds, especially of oils or other viscous liquids. But also the promotion of aqueous liquids and gases is possible if one. the recesses and the spaces between the cylindrical body and the housing, respectively holds tight.
