Description
Kolbenpumpe, bei welcher sich in einem Gehäuse ein zylindrischer Körper dreht, welcher parallel zu einer Achse mehrere Pumpenzylinder enthält Gegenstand vorliegender Erfindung ist eine Kolbenpumpe, welche in erster Linie für die Zuführung der Viskose zu den Spinndüsen in der Kunstseidenfabrikation bestimmt ist, jedoch auch für 01 und andere Flüssigkeiten gebraucht werden kann.Piston pump in which a cylindrical body is located in a housing rotates, which contains several pump cylinders parallel to an axis object The present invention is a piston pump which is primarily used for feeding the viscose is intended for the spinnerets in the rayon manufacture, however can also be used for 01 and other liquids.
Es sind bereits Kolbenpumpen für diese Verwendungszwecke bekannt, bei welchen sich in einem Gehäuse ein zylindrischer Körper dreht, welcher parallel zu einer Achse mehrere Pumpenzylinder enthält und welcher als Steuerdrehschieber wirkt, indem bei seiner Umdrehung abwechselnd jeder Zylinder mit einem in dein Gehäusedeckel befindlichen Saugkanal und einem im Gehäusedeckel oder im Gehäuse befindlichen Druckkanal in Verbindunggebracht wird.Piston pumps are already known for these purposes, in which a cylindrical body rotates in a housing, which parallel to one axis contains several pump cylinders and which as a control rotary valve works by alternating each cylinder with one in your housing cover during its rotation suction channel located and a pressure channel located in the housing cover or in the housing is associated.
Bei diesen Pumpen bestand jedoch der Übelstand, daß auf die Kolben nicht nur axiale, sondern auch seitliche Kräfte einwirkten, was einen sehr raschen Verschleiß der-:elben und der die Kolben aufnehmenden Zylinder bzw. Bohrungen herbeiführte.With these pumps, however, there was the disadvantage that on the pistons Not only axial but also lateral forces acted, which is very quick Wear of the same and the cylinder or bores receiving the pistons brought about.
Dieser L belstand wird bei der Kolbenpumpe gemäß der Erfindung dadurch behoben, daß die Kolben durch Mitnehmer bewegt werden, welche in der Verlängerung der Kolben ini Zylinderkörper geführt sind.This L belstand is in the piston pump according to the invention fixed that the pistons are moved by drivers, which are in the extension the pistons are guided in the cylinder body.
rin Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt, und zwar zeigt: Fig. 1 und a je einen Längsschnitt durch die Pumpe, Fig. 3 und -. je einen Querschnitt durch die Pumpe, Fig.5 zeigt einen "Peillängsschnitt durch die Pumpe und Fig.6 einen "Peilquerschnitt durch die Pumpe.An exemplary embodiment of the subject matter of the invention is shown in the drawing shown, namely: Fig. 1 and a each a longitudinal section through the pump, Fig. 3 and -. each a cross section through the pump, Fig.5 shows a "longitudinal section of the bearing through the pump and Fig. 6 a "Peilquences through the pump.
Fig. 7 ist eine schematische Darstellung des Hubwerkes.Fig. 7 is a schematic representation of the hoist.
Gemäß Fig. t und 2 besteht diese Pumpe im wesentlichen <ins einem zylindrischen Körper, welcher aus mehreren Stücken t, 2, 3 zusammengesetzt sein kann und sich, von der Welle 4 angetrieben, in dein Gehäuse 5 dreht. Dieser zylindrische liörper enthält, parallel zu seiner Achse, eine Anzahl Zylinder (i, deren Kolben ; durch eine schräge Hubscheibe 8 und einen uin den festen Zapfen c1 schwingenden Stern to oder durch eine andere Einrichtung ihre hin und her gehende Bewegung erhalten. Im Deckel i i (Fig. i. 2 und 3) oder im Gehäuse 5 (Fig. 5 und 6) sind Saugkanäle 1 2 und Druckkanäle 13 angeordnet, init welchen bei Drehung des Körpers i die einzelnen Zylinder 6 abwechselnd in Verbindung gebracht werden. Der Körper i, welcher die Zylinder enthält, ist also zugleich Steuerorgan.According to Fig. T and 2, this pump consists essentially <in one cylindrical body, which can be composed of several pieces t, 2, 3 can and, driven by the shaft 4, rotates in your housing 5. This cylindrical one li body contains, parallel to its axis, a number of cylinders (i, whose pistons ; by an inclined cam disc 8 and a swinging uin the fixed pin c1 Stern to or through some other facility to receive their reciprocating motion. In the cover i i (Fig. I. 2 and 3) or in the housing 5 (Fig. 5 and 6) there are suction channels 1 2 and pressure channels 13 arranged, init which upon rotation of the body i the individual Cylinder 6 are alternately connected. The body i, which the Contains cylinder, so it is also the control element.
Die Kolben 7 werden nicht unmittelbar von der schrägere, Scheibe 8 betätigt, sondern sie werden von Mitnehmern 1 ¢ mitgenommen, welche im Zylinderkörper a und 3 geführt sind und die von der schrägen Hubscheibe 8 herrührenden seitlichen Kräfte aufnehmen, ohne sie auf die Kolben 7 zu übertragen.The pistons 7 are not directly supported by the inclined disk 8 operated, but she are taken along by carriers 1 ¢, which are guided in the cylinder body a and 3 and the originating from the inclined lifting disc 8 absorb lateral forces without transferring them to the piston 7.
Die Kolben 7 sind mit den Mitnehmern 1 4. durch Bajonettverschluß ähnliche Fortsätze 15 mit geringem Spiel verbunden. Die seitlichen Kräfte, herrührend von der Hubscheibe 8 und von der schwingenden, sternförmigen Scheibe io, werden von den Mitnehmern allein aufgenommen.The pistons 7 are with the drivers 1 4th by a bayonet lock similar projections 15 associated with little play. The lateral forces, originating from the lifting disk 8 and from the oscillating, star-shaped disk io picked up by the drivers alone.
Das Hubwert: bestellt aus einer festen Hubscheibe 8, welche die Kolben verschiebt und deren Neigung zum Zwecke der Veränderulig des Kolbenhubes zur Pumpenachse verstellt werden kann, sowie aus einem um einen festen Zapfen g auf der Pumpenachse schwingenden Stern io_, welcher die Mitnehmet und den Kolben zurückbringt. Derartige bekannte Einrichtungen, welche übrigens immer ohne Mitnehmet unmittelbar auf die Kolben einwirken, haben den Fehler, daß sie zu große freie Ausladungen der hin und her gehenden Teile ergeben, weil Hubscheibe und schwin- g r ilcle Scheibe an einem Ende des Kolbens e angreifen. Diese Nachteile sind gemäß Fig. 7 dadurch beseitigt, daß abgesehen von der Verwendung der @littiehmer, Hubscheiben 8 und Stern io nicht, wie gewöhnlich, beide an einem Ende des hin und her gehenden Teiles 14. angreifen, sondern sie sind voneinander so weit entfernt, daß zwischen ihnen für den Mitnehmet 1.4 oder für den Kolben, falls der Mitnehiner weggelassen wird, eine Führung 34 im Zylinderkörper Platz findet, wodurch die freie Ausladung bedeutend vermindert wird. Das Weglassen der Mitnehiner, an deren Stelle die verlängerten Kolben zwischen der Scheibe 8 und dein Stern io geführt würden, würde an dem Wesen der hier erzielten Wirkung nichts ändern.The stroke value: ordered from a fixed stroke disc 8, which moves the piston and whose inclination can be adjusted for the purpose of changing the piston stroke to the pump axis, as well as from a star io_ swinging around a fixed pin g on the pump axis, which drives the piston and the piston brings back. Such known devices, which in fact always act directly on the piston without Mitnehmet have the defect that they result in too large a free projections of the reciprocating parts, because lifting and vibration g r ilcle disc engage one end of the piston e. These disadvantages are eliminated according to FIG. 7 in that, apart from the use of the @littiehmer, lifting disks 8 and star io, they do not, as usual, both act on one end of the reciprocating part 14, but they are so far apart from one another that between them for the driver 1.4 or for the piston, if the driver is omitted, a guide 34 is located in the cylinder body, whereby the free projection is significantly reduced. The omission of the Mitnehiner, in the place of which the elongated pistons would be guided between the disc 8 and your star io, would not change the essence of the effect achieved here.
