Description

Hochdruckdichtung für Pumpen Bei Hochdruckpumpen, die ständig gegen hohe Drücke (300 -400 atü) gefahren werden, zeigt sich die Erscheinung, daß die hintere, am Tauchkolben anliegende Manschettenkante in den Spalt zwischen der Rückenabstützung und dem Kolben kriecht. Die Folgen hiervon sind eine an dieser Stelle beginnende Auflösung der Manschette und eine Riefenbildung auf dem Kolben, welche ebenfalls zu einer vorzeitigen Zentörung der Manschettengleitfläche und damit der Manschette führt.High pressure seal for pumps For high pressure pumps that constantly oppose high pressures (300 -400 atü) are driven, the phenomenon shows that the the rear edge of the cuff resting against the plunger into the gap between the back support and the piston creeps. The consequences of this are beginning at this point Dissolution of the cuff and a scoring on the piston, which also to a premature destruction of the cuff sliding surface and thus the cuff leads.

Diesen Nachteil zu beseitigen, hat sich die vorliegende Er findung zur Aufgabe gemacht. Die Erfindung kennzeichnet sich dadurch, daß die Manschette 2 und der Stützring 4 eine Berührungsfläche 8 besitzen, die in Richtung auf Punkt A gesehen, rückwärts geneigt ist.To eliminate this disadvantage, the present invention he has made a task. The invention is characterized in that the cuff 2 and the support ring 4 have a contact surface 8 in the direction of point A is seen tilted backwards.

Damit erhalten die vom Mediumdruck ausgehenden Kräfte eine vom Punkt A abweisende Komponente; die Manschette wird hier entlastet und hat weniger Neigung in den Spalt zu wandern.This gives the forces emanating from the medium pressure one from the point A repellent component; the cuff is relieved here and has less inclination to wander into the crevice.

Die Neigung der Rückenabstützung hängt von der gewählten E-lastizität des Manschettenmaterials ab.The inclination of the back support depends on the elasticity selected of the cuff material.

Der Erfindungsgegenstand ist in den Figuren 1 und 2 dargestellt.The subject of the invention is shown in FIGS. 1 and 2.

Während Figur 1 eine Dichtmanschette zeigt, welche durch einen elastischen Ring 7 eine elastische Vorspannung in axialer Richtung erhält, ist in Figur 2 eine axial fest eingespannte Manschette, eine sogenannte Blockmanschette dargestellt.While Figure 1 shows a sealing sleeve, which by an elastic Ring 7 receives an elastic bias in the axial direction, is one in Figure 2 axially firmly clamped cuff, a so-called block cuff shown.

Mit 1 ist der Hochdruckkolben bezeichnet, welcher durch Exenter und Pleuel seine Hubbewegung erhält. Die Hochdruckmanschette ist mit 2 gekennzeichnet. Sie liegt mit der Toleranz-Ausgleichscheibe 3 und der mit der erfindungsgemäß ausgebildeten Fläche 8 versehenen Druckscheibe 4 in dem im Ausschnitt dargestellten Pumpengehäuse 5. Der Dichtungsraum wird durch eine fest s anliegende Brille 6 verschlossen.1 with the high pressure piston is referred to, which by eccentric and Connecting rod receives its stroke movement. The high pressure cuff is marked with 2. It lies with the tolerance compensating disk 3 and with the one designed according to the invention Surface 8 provided pressure washer 4 in the pump housing shown in the cutout 5. The sealing space is tightly attached by a s Glasses 6 locked.

Mit 7 ist ein elastischer Ring bezeichnet. A ist der Bezugspunkt für die Rückwärtsneigung der ManschettenabstUtzung.With 7 an elastic ring is designated. A is the reference point for the backward inclination of the cuff support.

Mit B ist der Raum bezeichnet, in dem der Druck des Pördermediums entsteht.B is the space in which the pressure of the pumped medium arises.
