Description
Drehkolbenpumpe mit in der Kolbentrommel radial unter Federwirkung verschiebbaren Kolben Die Erfindung bezieht sich auf eine Drehkolbenpumpe mit in der Kolbentrommel radial unter Federwirkung verschiebbaren Kolben und zwecks Abdichtung an der Kolbentrommel verschiebbarem Widerlager.Rotary lobe pump with radial spring action in the piston drum displaceable piston The invention relates to a rotary lobe pump with in the piston barrel radially displaceable piston under spring action and for the purpose of sealing on the piston drum movable abutment.
Pumpen dieser Art sind bereits bekannt und sind z. B. für die Förderung von Wasser und anderen Flüssigkeiten vorgeschlagen worden.Pumps of this type are already known and are, for. B. for funding suggested by water and other liquids.
In der Viskoseseideindustrie werden an die Gleichmäßigkeit der geförderten Flüssigkeitsmengen große Anforderungen gestellt, d. h. die in gleichen Zeiten geförderten Flüssigkeitsmengen sollen möglichst die gleichen sein; außerdem sollen die verwendeten Pumpen derart sein, daß man die Größe der geförderten Flüssigkeitsmengen leicht regeln kann.In the viscose silk industry, the consistency of the promoted Large demands are placed on the quantities of liquid, d. H. those funded at the same time The amount of liquid should be the same as possible; in addition, the used Pumps should be such that one can easily determine the size of the quantities of liquid being pumped can regulate.
Die bis jetzt verwendeten Pumpen genügen besonders der Anforderung nicht, daß die Fördermengen verschiedener Spinnpumpen in einfacher und genauer Waise ganz gleich gemacht werden können, eine der wichtigsten Aufgaben der Kunstseideindustrie mit Rücksicht auf die Gleichmäßigkeit des Erzeugnisses.The pumps used up to now particularly meet the requirement not that the delivery rates of different spinning pumps in a simple and precise orphan can be done in the same way, one of the most important tasks of the rayon industry with regard to the evenness of the product.
Die Pumpe nach der Erfindung hat die genannten Nachteile nicht und kann, außer in der Kunstseideindustrie, in allen: Fällen Verwendung finden, wo man gleiche und regelbare Flüssigkeitsmengen in gleichen Zeiträumen zu fördern hat, z. B. 0l u. dgl. Die Erfindung besteht darin, daß der die zylindrische Wandung des Arbeitsraumes bildende Gehäuseteil aus einer Zwischenplatte besteht, die zur Regelung der Fördermenge der Pumpe gegenüber der Kolbentrommel radial verstellbar ist.The pump according to the invention does not have the disadvantages mentioned and can be used in all cases, except in the rayon industry, wherever has to convey the same and controllable amounts of liquid in the same time periods, z. B. Ol and the like. The invention consists in that the cylindrical wall of the The housing part forming the working space consists of an intermediate plate which is used for regulation the delivery rate of the pump is radially adjustable with respect to the piston drum.
In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise angegeben, und zwar stellt Abb. i einen Schnitt durch die Pumpe dar und Abb. 2 eine Aufsicht auf die Zwischenplatte nach der Linie II-II der Abb. r nach Wegnahme des Vorderteiles des Gehäuses.In the drawing is an embodiment of the subject matter of the invention given for example, namely Fig. i shows a section through the pump and Fig. 2 is a plan view of the intermediate plate along the line II-II of Fig. r after removing the front part of the housing.
b ist die Kolbentrommel, welche mit Schieberkolben d versehen und auf -der Welle c befestigt ist, die mittels eines nicht dargestellten Zahnrades von der Maschine angetrieben wird. Die Kolbentrommel dreht sich in einem Gehäuse a, mit dem sie den Arbeitsraum g bildet. l ist das Widerlager, welches den Saug- und Druckraum der Pumpe trennt und welches mittels einer Stellschraube in gegen die Trommel gedrückt werden kann. Die Kolben d werden durch die Schraubenfeder e auseinandergedrückt, so daß sie stets mit ihren äußeren Enden gegen die Wand des Pumpengehäuses angedrückiwerden. Beim Vorübergang der Kolben an dem Widerlager werden sie in die Trommel eingedrückt. Die hierdurch entstehende Vergrößerung des Druckraumes würde ein entsprechendes Zurücksaugen eines Teiles der Flüssigkeit veranlassen. Um diesem vorzubeugen, sind die zwei Kolben in bekannter Weise- über ihrer ganzen Länge mit einer Durchbohrung f versehen, welche immer mit Flüssigkeit gefüllt ist und wodurch der von dem Kolben verdrängte Teil der sich in dem Schlitz der Kolbentrommel befindenden Flüssigkeit herausgedrückt und der Druckraum mit der richtigen Flüssigkeitsmenge ausgefüllt wird. h und iz sind die Zu- und Abflußleitungen der Flüssigkeit.b is the piston drum, which is provided with slide piston d and is mounted on the shaft c, which is by means of a gear, not shown driven by the machine. The piston drum rotates in a housing a, with which it forms the working space g. l is the abutment that supports the suction and pressure chamber of the pump separates and which by means of an adjusting screw in opposite the drum can be pushed. The pistons d are driven by the coil spring e pressed apart so that they always with their outer ends against the wall of the The pump housing. When passing the piston will be on the abutment pressed them into the drum. The resulting enlargement of the pressure space would be a corresponding Sucking back part of the liquid cause. To prevent this, the two pistons are in the known manner over its entire length is provided with a through-hole f, which is always filled with liquid is filled and whereby the part displaced by the piston is in the slot the piston drum located liquid pressed out and the pressure chamber with the correct amount of liquid is filled. h and iz are the inflow and outflow lines the liquid.
Das Gehäuse besteht aus einer Vorder- Z und Hinterplatte j und einer Zwischenplatte h, welche mit Schrauben p zusammengehalten werden. Diese Zwischenplatte h, in welcher die Trommel b sich dreht, ist mittels Stellschrauben q mit Mikrometergewinde verstellbar, so daß zur Regelung der Fördermenge der Arbeitsraum vergrößert oder verkleinert werden kann. Die Stellschrauben g gehen durch zwei am Gehäuse befestigte Platten r hindurch und bewirken die Verschiebung der Zwischenplatte gegen die Vor-und Hinterplatte der Pumpe sowie gegen die Trommel. In der Zwischenplatte sind Langlöcher s angebracht, durch welche die Schraubenp hindurchgehen und welche die Verschiebung der Zwischenplatte gestatten. Die Zwischenplatte h und das Abschlußstück Z können aus gehärtetem Stahl und die Kolben aus weichem Werkstoff hergestellt werden, so daß sich nur die letzteren abnutzen.The housing consists of a front Z and rear panel j and one Intermediate plate h, which are held together with screws p. This intermediate plate h, in which the drum b rotates, is by means of adjusting screws q with micrometer thread adjustable, so that the working space is enlarged or to regulate the delivery rate can be reduced in size. The adjusting screws g go through two attached to the housing Plates r through and effect the displacement of the intermediate plate against the front and back Back plate of the pump as well as against the drum. There are elongated holes in the intermediate plate s attached, through which the screws pass and which the displacement allow the intermediate plate. The intermediate plate h and the end piece Z can made of hardened steel and the pistons made of soft material, so that only the latter wear out.
