KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
Kapselpumpen, bei denen ein rotierender Zylinder exzentrisch und die Innenwand berührend in einem Gehäuse (Kapsel) gelagert ist und ein den Zylinder durchquerender, in ihm verschiebbarer, einheitlicher oder geteilter Druckflügel das Bewegungsorgan der zu fördernden Flüssigkeit bildet, zeigen den Übelstand, daß sich dem Druckflügel bedeutende Bewegungshindernisse . durch dieCapsule pumps in which a rotating cylinder is eccentric and in contact with the inner wall is mounted in a housing (capsule) and a cylinder traversing, sliding in it, unitary or divided Pressure vane forms the organ of movement of the liquid to be conveyed, show the drawback that the pressure vane is significant Obstacles to movement. through the
ίο Reibung in dem Zylinderschlitze entgegenstellen. 'ίο Oppose friction in the cylinder slots. '
Dieser Übelstand folgt daraus, daß sich der Druckflügel in dem rotierenden Zylinder verschieben muß, während zu beiden Seiten die Druckdifferenz zwischen der Saugleituhg und der Druckleitung besteht. Indem dadurch der Druckflügel einseitig an die entsprechende Führungsfläche des Schlitzes im Zylinder gepreßt wird,. erfährt er erhebliche Abnutzung und vermindert wesentlich den mechanischen Nutzeffekt der Pumpe.This inconvenience follows from the fact that the pressure vane is in the rotating cylinder must move, while on both sides the pressure difference between the Saugleituhg and the pressure line exists. By doing this, the pressure wing on one side to the corresponding Guide surface of the slot in the cylinder is pressed. he experiences considerable Wear and tear and significantly reduces the mechanical efficiency of the pump.
Den genannten Mangel zu beseitigen, ist der Zweck der nachfolgend beschriebenen Erfindung, die im wesentlichen besteht in der Anwendung von zwei hintereinander geschalteten Kapselpumpen mit weiten Durchgangsöffnungen und versetzten Druckflügeln, \vobei die innere Begrenzung der Kapseln in besonderer, bereits bekannter Weise geformt ist.The purpose of the one described below is to eliminate the aforementioned defect Invention which essentially consists in the use of two series-connected Capsule pumps with wide through openings and offset pressure vanes, with the inner limitation of the capsules in special, already known way is shaped.
Fig. ι zeigt zwei nebeneinander stehende gleiche Kapselpumpen, an deren einer zunächst die besondere Form selbst erläutert werden, möge. In jeder Kapsel dreht sich der exzentrisch gelagerte Zylinder c, der von dem ungeteilten Druckflügel / durchquert wird.Fig. Ι shows two adjacent identical capsule pumps, one of which initially the particular shape itself may be explained. In each capsule it rotates eccentrically bearing cylinder c, which is traversed by the undivided pressure wing /.
Die innere Begrenzung der Kapsel wird in bekannter Art gebildet durch die beiden einander gegenüberstehenden, aus der Zylinderachse beschriebenen Kreisbögen von verschiedenen Radien zwischen α b bezw. a{ O1. Diese Kreisbögen sind verbunden durch die Übergangskurven zwischen a U1 bezw. b bY von solcher Form, daß die Verbindungslinien zwischen Punkten der einen Kurve durch die Zylinderachse nach entsprechenden Punkten der anderen Kurve konstante Länge haben, so daß der ungeteilte Druckflügel f beim Rotieren mit dem Zylinder c immer gegenüberliegende Punkte der Kapsel berührt. Bei der beschriebenen Form der Kapsel erfolgt nun ersichtlich die Verschiebung des Druckflügels im Zylinder nur durch die Ubergängskurven, während er in den Stellungen zwischen "den Kreisbögen keine Verschiebung erfährt.The inner boundary of the capsule is formed in a known manner by the two opposing arcs of different radii between α b and described from the cylinder axis. a { O 1 . These arcs are connected by the transition curves between a U 1 respectively. bb Y of such a shape that the connecting lines between points of one curve through the cylinder axis to corresponding points of the other curve have constant length, so that the undivided pressure wing f always touches opposite points of the capsule when rotating with the cylinder c. In the case of the described shape of the capsule, the displacement of the pressure vane in the cylinder now takes place only through the transition curves, while it does not experience any displacement in the positions between "the arcs of the circle.
Der Druckflügel / soll nun Arbeit leisten nur während der Bewegung innerhalb der Kreisbögen, während er also in bezug auf ' den Zylinder in Ruhe ist. Zu dem Ende liegen die Ein- und Austrittsöffnungen in j dem von den Übergangskurven gebildeten : Teile des Kapselumfanges und erstrecken sich zweckmäßig über diesen ganzen Teil. Damit werden gleichzeitig große Durchgangsöffnungen gewonnen.The pressure wings / should now work is done only during the movement within the circular arcs, so while it is the cylinder alone with respect to '. At the end, the inlet and outlet openings are in the one formed by the transition curves: parts of the capsule circumference and expediently extend over this entire part. In this way, large through openings are obtained at the same time.
Bei einer einzelnen derartigen Kapselpumpe sind nun aber, während der Druckflügel sich in den Stellungen zwischen den Übergangskurven befindet (Fig. 1 rechts), die Saug- und Druckleitung nicht voneinander getrennt. Um das zu erreichen, werden zwei gleiche Kapsel-In the case of a single capsule pump of this type, however, the pressure vanes are themselves located in the positions between the transition curves (Fig. 1 right), the suction and Pressure line not separated from each other. To achieve this, two identical capsule
pumpen (Fig. ι) hintereinander geschaltet, deren Druckflügel bei übereinstimmender Lage der beiden Kapseln senkrecht zueinander stehen. Die beiden Druckflügel haben gleiche Winkelgeschwindigkeit, und während deshalb der eine (Fig. ι links) Arbeit leistend sich innerhalb der Kreisbogenteile bewegt, nimmt der andere (Fig. ι rechts) Stellungen zwischen den Übergangskurven ein, bietet also der vonpumps (Fig. ι) connected in series, the pressure vanes in the same position of the two capsules are perpendicular to each other. The two pressure wings have the same Angular velocity, and therefore the one (Fig. Ι left) doing work Moved within the arc parts, the other (Fig. ι right) takes positions between the transition curves, so that of
ίο dem ersten Druckflügel geförderten Flüssigkeit freien Durchgang durch die Kapsel, wäh-•rend er umgekehrt seinerseits bei der Bewegung zwischen den Kreisbogenteilen Arbeit leistet, der erstere dann ohne Arbeitsleistung der Flüssigkeit Durchgang gewährt. Bei der Drehung der beiden Druckflügel vertauschen sie abwechselnd ihre Rollen als Arbeit leistende, sich nicht in ihrem Zylinder verschiebende, und als nicht Arbeit leistende, durch die Übergangskurven in ihrem Zylinder verschobene Organe.ίο the liquid conveyed to the first pressure vane free passage through the capsule, while he vice versa in turn when moving does work between the arc parts, the former then without work the liquid is allowed to pass through. Swap the two pressure blades when turning they take turns doing their roles as work, not shifting in their cylinder, and as not doing work, displaced by the transition curves in their cylinder Organs.
Ersichtlich wird durch diese Anordnung die erforderliche Trennung der Saug- und Druckleitung erzielt.The required separation of the suction and suction can be seen through this arrangement Pressure line achieved.
In der konstruktiven Durchbildung werden die beiden Kapselpumpen zweckmäßig vereinigt, indem (Fig. 2 Schnitt in Richtung der Achse, Fig. 3 Ansicht von oben) ein gemeinschaftlicher Zylinder c von entsprechender Breite die beiden durch die Zwischenwand % getrennten Druckflügel enthält. In den Fig. 1, 2 und 3 sind die Ein- und Austrittsöffnungen der beiden Kapseln, so weit sichtbar, durch die gleichen Buchstaben O1 O2 os O4 bezeichnet.In the structural design, the two capsule pumps are appropriately combined in that (Fig. 2 section in the direction of the axis, Fig. 3 view from above) a common cylinder c of the appropriate width contains the two pressure vanes separated by the partition wall%. In FIGS. 1, 2 and 3, the inlet and outlet openings of the two capsules, so far visible, are denoted by the same letters O 1 O 2 o s O 4.
Es ist klär, daß die beiden Kapselpumpen zum Z\vecke des beschriebenen Zusammenwirkens nicht vollständig gleich zu sein brauchen, wie auch das genaue Einhalten der sonstigen Bedingxmg'en nicht erforderlich ist.It is clear that the two capsule pumps for the purpose of the cooperation described do not need to be completely the same, nor is it necessary to adhere precisely to the other conditions.
So können beispielsweise die beiden Viertelkreisbögen nach Befinden auch größer als ° sein, wenn dadurch die Übergangskurven nicht zu steil werden. Notwendig ist nur in allen Fällen die gleiche Winkelgeschwindigkeit der Druckflügel bei angemessener Stellung zueinander.For example, the two quadrant arcs can also be larger than ° if this does not make the transition curves too steep. Only in in all cases the same angular velocity of the pressure vanes with an appropriate position to each other.
Bei der beschriebenen Doppelkapselpumpe ergibt sich auch der Vorteil, daß die Druckflügel nicht nur keine einseitigen Pressungen gegen ihre Schlitzführungen erfahren, sondern daß sie auch während ihrer Verschiebung in der Längsrichtung vollständig entlastet sind, da an ihren beiden Stirnseiten (Fig. 1 rechts) während dieser Zeit derselbe Druck herrscht, so daß die. Übergangskurven nur die verhältnismäßig geringe Massenbeschleunigung zu leisten haben, was ganz besonders bei größeren Förderhöhen ins Gewicht fällt.In the double capsule pump described there is also the advantage that the pressure vanes not only do not experience one-sided pressing against their slot guides, but that they are completely relieved even during their displacement in the longitudinal direction, since the same pressure prevails on both of its front sides (Fig. 1 right) during this time, So that the. Transition curves only the relatively low mass acceleration have to do, which is particularly important in the case of higher funding levels.
