Description

Stopfbüchse mit Wasserkühlung für Wellen von Heißwasserpumpen u. dgl. Die vorliegende Erfindung bezieht sich auf eine Verbesserung der Stopfbüchse mit Wasserkühlung für Wellen von HeißwasserförderernnachdemHauptpatent495 i74. Beim Hauptpatent ist unmittelbar hinter der Stopfbüchse im Innern des Pumpengehäuses auf der Welle ein Schleuderrad so befestigt, daß durch dasselbe sowohl eine Druckverminderung an der Stopfbüchse als auch ein schnellerer Wärmeaustauch zwischen dem Fördermittel und dem Kühlmantel der Stopfbüchse bewirkt wird.Stuffing box with water cooling for shafts of hot water pumps and the like. The present invention relates to an improvement in the stuffing box with Water cooling for shafts of hot water conveyors according to main patent 495 i74. At the The main patent is immediately behind the stuffing box inside the pump housing a centrifugal wheel is attached to the shaft in such a way that it also reduces the pressure at the stuffing box as well as a faster heat exchange between the conveying means and the cooling jacket of the stuffing box.

Durch die vorliegende Erfindung wird diese Stopfbüchse weiter dadurch verbessert bzw. vervollkommnet, daß die hinter der Stopfbüchse liegende Pumpe mit einem besonderen Kühler verbunden ist, so daß das aus dem Pumpenraum bzw. der Entlastungsvorrichtung in den Raum hinter der Stopfbüchse tretende heiße Fördermittel mittels der Pumpe in Umlauf durch den Kühler versetzt und zur Stopfbüchsenkühlung benutzt wird. Dadurch wird es möglich, die Kühlung der Stopfbüchse ohne fremdes Wasser nur unter Benutzung desjenigen, welches aus dem Kreislauf des Förderers selbst stammt, wirksam herbeizuführen, da ja die Kühloberfläche des außerhalb der Pumpe angeordneten Kühlers beliebig gewählt werden kann. Das diesen Kühler durchlaufende heiße Fördermittel kann daher beliebig niedergekühlt werden.The present invention further enhances this gland improved or perfected that the pump located behind the stuffing box with a special cooler is connected, so that the from the pump room or the relief device Hot conveying medium entering the space behind the stuffing box by means of the pump is put into circulation through the cooler and used to cool the stuffing box. Through this it becomes possible to cool the stuffing box without using external water to effectively bring about that which comes from the circuit of the conveyor itself, since the cooling surface of the cooler arranged outside the pump can be chosen arbitrarily can be. The hot conveying means passing through this cooler can therefore be arbitrary be cooled down.

In zwei Ausführungsbeispielen ist der Erfindungsgegenstand in der Zeichnung dargestellt, und zwar zeigt Abb. i eine Ausführungsform mit Schraubenpumpe hinter der Stopfbüchse, Abb.2 eine solche mit Zentrifugalpumpe hinter der Stopfbüchse.In two exemplary embodiments, the subject matter of the invention is in Drawing shown, namely Fig. I shows an embodiment with a screw pump behind the stuffing box, Fig. 2 one with a centrifugal pump behind the stuffing box.

In Abb. i ist A der Saugraum einer Zentrifugalpumpe oder der Raum auf der Druck-Seite hinter der Entlastungsvorrichtung. In diesen Räumen herrscht ein mindestens der Wassertemperatur entsprechender Druck. Zwischen der Wellenstopfbüchse und dem Raum A ist nun eine Schraubenpumpe S derart angeordnet, daß in dem Raum B zwischen der Pumpe S und der Stopfbüchse ein Unterdruck entsteht, wodurch das aus dem Raum A tretende heiße Wasser nicht direkt zur Stopfbüchse gelangen kann, sondern durch die Wirkung der Pumpe P seinen Lauf durch den Kühler h nehmen muß; in dem das Wasser j e nach Ausführung des Kühlers beliebig weit heruntergekühlt werden kann. Es tritt also mit niedriger Temperatur in den Raum Bein und durch die Stopfbüchse nicht als Dampf, sondern als Wasser aus. Nebenbei ergibt sich noch der Vorteil eines niedrigeren Druckes in dem Raum B als in. dem Raum A. In Fig. I, A is the suction space of a centrifugal pump or the space on the pressure side behind the relief device. The pressure in these rooms is at least equal to the water temperature. Between the shaft stuffing box and the space A, a screw pump S is now arranged in such a way that a negative pressure is created in space B between the pump S and the stuffing box, whereby the hot water emerging from space A cannot reach the stuffing box directly, but through the Effect of the pump P must take its course through the cooler h; in which the water can be cooled down as far as desired, depending on the design of the cooler. It therefore enters the Bein room at a low temperature and exits through the stuffing box not as steam, but as water. In addition, there is the advantage of a lower pressure in room B than in room A.

In Abb. 2 ist eine Ausführungsform gegeben, bei der an Stelle der Schraubenpumpe P eine Zentrifugalpumpe C angeordnet ist.In Fig. 2 an embodiment is given in which instead of Screw pump P a centrifugal pump C is arranged.

Es ist die Möglichkeit gegeben, das aus dem Kühler austretende Kühlwasser noch zur Kühlung der Pumpenlager zu benutzen.It is possible to use the cooling water emerging from the radiator still to be used for cooling the pump bearings.
