Description

Förderpumpe, insbesondere mit zwei parallel zueinander angeordneten Zylindern Bei den bekannten Antrieben von Förderpumpen mit zwei parallel zueinander angeordneten Zylindern, deren Kolben durch zueinander versetzt an beidenEnden einer Schneckenradwelle angeordnete Kurbeln angetrieben werden, arbeiten diese Getriebe frei im Druckraum der Pumpe und kommen ständig mit der zu fördernden Flüssigkeit in Berührung, so daß ein unruhiges Arbeiten nicht ausgeschlossen und eine Abdichtung der durchtretenden Schneckenradwelle durch Stopfbüchsen erforderlich ist.Feed pump, in particular with two arranged parallel to one another Cylinders In the known drives of feed pumps with two parallel to each other arranged cylinders, the pistons of which are offset from one another at both ends of a Cranks arranged on a worm gear shaft are driven, these gears work free in the pressure chamber of the pump and constantly come with the liquid to be pumped in contact, so that a restless work is not excluded and a seal the worm wheel shaft passing through is required by stuffing boxes.

Durch die Erfindung wird diesen Übelständen dadurch abgeholfen, daß Schnecke und Schneckenrad innerhalb des Pttmpendruckraumes in einem gegen diesen stopfbüchsenlos abgedichteten Raum untergebracht sind. In der Zeichnung zeigt: Abb. i eine Vorderansicht des Antriebsgehäuses im Schnitt mit daran sitzenden Kolbenpumpen, Abb. 2 eine Seitenansicht und Abb. 3 eineDraufsicht,teilweise imSchnitt. Aus dem Antriebsgehäuse a ragt die sich schnell drehende Antriebswelle b außen hervor. Innen bildet diese Welle b eine Schnecke d, die in ein auf einer quer liegenden Welle f sitzendes Schneckenrad ä eingreift. Die Schnecke d und das Schneckenrad g befinden sich in einem besonderen abgeschlossenen dichten Raum la, in dessen seitlichen Wandungen die Lager für die Welle f mit äußeren Dichtungsscheiben sitzen. Auf den seitlich vorstehenden Enden der Welle f sind versetzt stehende Kurbeln i angebracht, die mittels Pleuelstangen k die auf und nieder gehenden Kolben in den Pumpen l bewegen. In dem Gehäuse a sind seitliche Öffnungen m mit Deckeln n vorgesehen, um das Herausnehmen der Kolben zu ermöglichen. Der abgeschlossene dichte Raum /z wird mit nicht flüssigem Schmiermaterial ausgefüllt, und da kein Wasser eintreten kann, werden Stopfbüchsen an den Durchtrittsstellen der Welle f hinfällig.The invention remedies these inconveniences in that Worm and worm wheel within the pressure chamber in one against it are housed sealed space without a stuffing box. In the drawing shows: Fig. i a front view of the drive housing in section with piston pumps attached to it, Fig. 2 is a side view and Fig. 3 is a top view, partly in section. From the Drive housing a, the rapidly rotating drive shaft b protrudes from the outside. Inside this shaft b forms a worm d, which in a on a transverse shaft f seated worm gear ä engages. The worm d and the worm wheel g are located in a special closed, tight room la, in the side walls the bearings for shaft f are seated with outer sealing washers. On the side protruding ends of the shaft f are offset standing cranks i attached, the Use connecting rods k to move the up and down pistons in pumps l. In the housing a, side openings m with covers n are provided for removal to allow the piston. The closed tight space / z becomes with non-liquid Filled with lubricant, and since no water can enter, stuffing boxes are used obsolete at the points of passage of the wave f.
