Description

Pumpe, insbesondere Spinnpumpe, für viskose Flüssigkeiten mit im Kreise angeordneten parallelen Kolben Die Erfindung betrifft eine umlaufende Pumpe zum Zuführen von Viskose zu den Spinndüsen von Spinnmaschinen für Kunstseide, bei der eine Anzahl im Kreise parallel angeordneter beweglicher Kolben die Förderung bewirkt.Pump, especially spinning pump, for viscous liquids with in a circle arranged parallel piston The invention relates to a circulating pump for Feeding viscose to the spinnerets of spinning machines for rayon, in which a number of movable pistons arranged in parallel in a circle causes the conveyance.

Das Wesen der Neuheit besteht darin, daß zur Kolbenhubverstellung und somit zur Fördermengenreglung die Schräge einer Taumelscheibe durch Änderung der axialen Lage einer Kugel verstellt wird, was in an sich bekannter Art von Hand über ein Schneckengetriebe und ein Schraubendruckstück geschehen kann.The essence of the novelty is that for piston stroke adjustment and thus the incline of a swash plate by changing the flow rate control the axial position of a ball is adjusted, which is done in a known manner by hand can be done via a worm gear and a screw thrust piece.

Die bisher bekannt gewordenen Pumpen dieser Art haben den Nachteil, daß die Kolben zwecks Erzielung einer Hubbewegung in einer umlaufenden Trommel angeordnet und mit dieser an einer schiefen Ebene vorbeigeführt werden und die hierdurch entstehenden Seitendrücke zu einer beschleunigten Abnutzung einzelner Pumpenteile führen, wodurch die Vorbedingung für das Erreichen einer dauernd gleichmäßigen Förderung nicht erfüllt wird. Bekannte Einstellvorrichtungen zur Änderung der Gesamtförderung bei diesen Pumpen hatten den Nachteil, ihre Wirkung durch eine Veränderung der Neigung jener zur Erzielung des Kolbenhubes benutzten schiefen Ebene auszuüben und dadurch die zur beschleunigten Abnutzung von Pumpenteilen führenden Seitenkräfte zu verändern.The pumps of this type that have become known so far have the disadvantage that the pistons are arranged in a rotating drum in order to achieve a reciprocating movement and with this are guided past an inclined plane and the resulting Side pressures lead to accelerated wear of individual pump parts, whereby the precondition for achieving constant, constant funding is not met will. Known adjusting devices for changing the total funding in these Pumps had the disadvantage of changing their effect by changing the inclination of those to exercise the inclined plane used to achieve the piston stroke and thereby the to change lateral forces leading to accelerated wear of pump parts.

Bei der den Gegenstand der Erfindung bildenden Pumpe zur Zuführung des Spinnmaterials zu den Spinndüsen sind diese Nachteile beseitigt. Die Zylinder der neuen Pumpe sind ortsfest, also im Pumpengehäuse selbst angeordnet. Die Hubbewegung der Kolben wird durch eine nicht umlaufende Taumelscheibe bewirkt, deren Verstellung zur Änderung der Gesamtförderung ohne jeden Einfluß auf die zur Erzielung des Kolbenhubes notwendigen Kräfte bleibt, die in jedem Falle absolut in die Richtung der Zylinderbohrung- und Kolbenachse fallen und zur Auswirkung kommen. Dadurch werden schädliche Seitenkräfte vermieden, die zur beschleunigten Abnutzung von Pumpenteilen führen. Die Steuerung der Saug-und Druckhübe geschieht durch eine mit Steuerkanälen versehene umlaufende Steuerscheibe, deren Bewegung im direkten Verhältnis zu der der Taumelscheibe erfolgt.In the case of the feed pump forming the subject of the invention of the spinning material to the spinnerets, these disadvantages are eliminated. The cylinders of the new pump are stationary, i.e. arranged in the pump housing itself. The lifting movement the piston is adjusted by a non-rotating swash plate to change the total delivery without any influence on the achievement of the piston stroke necessary forces remain, which in any case are absolutely in the direction of the cylinder bore and piston axis fall and come into effect. This creates harmful side forces avoided, which lead to accelerated wear of pump parts. The control the suction and pressure strokes are carried out by a circumferential control channel provided with Control disk, the movement of which is in direct proportion to that of the swashplate.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in zwei Abbildungen dargestellt, und zwar zeigt Abb. i die Vorrichtung im Längsschnitt, Abb. 2 eine Seitenansicht.The drawing shows an exemplary embodiment of the subject matter of the invention shown in two figures, namely Fig. i shows the device in longitudinal section, Fig. 2 is a side view.

Die Wirkungsweise der neuen Pumpe ist wie folgt: Der Eintritt des Spinnmaterials geschieht durch die Öffnung i und den Kanal 2 bis zur Steuerscheibe 3 (Abb. i), deren Saugkanal q. dann mit den Zylinderbohrungen g der in der Abbildung beispielsweise mit drei Kolben dargestellten Pumpe in Verbindung steht, wenn Kolben 6 einen Saughub ausführt. Beim Druckhub von Kolben 6 hat Steuerscheibe 3 den Saugkanal 4 an Zylinderbohrung 5 vorbeigeführt und ihn dadurch geschlossen. Dafür steht jetzt Druckkanal ? mit Zylinderbohrung 5 in Verbindung, und das Spinnmaterial kann durch Verbindungskanal 8 und Umlaufkanal g durch die Gehäusekanäle io und die Austrittsöffnung ii austreten. Die Steuerscheibe erhält ihren Antrieb durch Welle 12 mittels des Keiles 13. Der Druckhub von Kolben 6 wird herbeigeführt durch Kugelscheibe 14, die von Welle 12 durch Keil 15 mitgenommen wird. Eine Veränderung der Gesamtfördermenge wird bewirkt durch Drehen des Knopfes 16 (Abb. 2), damit der Schnecke 17 und des Schneckenrades 18, wodurch sich Druckstück ig verschiebt und Kugel go mehr oder weniger durch die Ofrnung 21 der Kugelscheibe 14 hindurchschiebt. Weil Kugel 2o als Widerlager für die frei auf Welle 12 sitzende Taumelscheibe 22 dient, erhält diese eine mehr oder weniger große den Kolbenhub verursachende Neigung. Das Mitlaufen der frei im Gehäuse 23 schwingenden Taumelscheibe 22 wird verhindert durch Gleitstücke 24. Der Saughub der Kolben 6 wird herbeigeführt durch Kolbenscheibe 25, die mittels der Kugelscheiben 26 die kugelförmigen Köpfe 27 der Kolben 6 gegen Taumelscheibe 22 drückt. Der zentrale Druck wird ausgeübt mittels Feder 28 über das Druckstück 29. Die Saug- und Druckkammer 30 erhält ihre Abdichtung durch Deckel 31, der zur Abdichtung der Welle 12 die Stopfbüchse 32 aufnimmt.The new pump works as follows: The entry of the Spinning material happens through opening i and channel 2 to the control disk 3 (Fig. I), whose suction channel q. then with the cylinder bores g in the figure for example, the pump shown with three pistons is in communication when piston 6 performs a suction stroke. During the pressure stroke of piston 6 has control disc 3, the suction channel 4 is guided past the cylinder bore 5 and thereby closed. This is what Druckkanal now stands for? with cylinder bore 5 in connection, and the spinning material can through the connection channel 8 and circulation channel g through the housing channels io and the Exit outlet ii. The control disk is driven by a shaft 12 by means of the wedge 13. The pressure stroke of piston 6 is brought about by a spherical disk 14, which is carried along by shaft 12 by wedge 15. A change in the total flow rate is effected by turning the knob 16 (Fig. 2) so that the worm 17 and the Worm wheel 18, whereby the pressure piece moves ig and ball go more or less pushes through the opening 21 of the spherical disk 14. Because bullet 2o serves as an abutment for the swash plate 22 seated freely on shaft 12, receives this a more or less large inclination causing the piston stroke. The running the swash plate 22 swinging freely in the housing 23 is prevented by sliding pieces 24. The suction stroke of the piston 6 is brought about by piston disk 25, which means the spherical disks 26, the spherical heads 27 of the pistons 6 against the swash plate 22 presses. The central pressure is exerted by means of a spring 28 via the pressure piece 29. The suction and pressure chamber 30 is sealed by cover 31, which is used for Sealing of the shaft 12, the stuffing box 32 receives.
