Description

Vorrichtung zum Ändern des Hubes von Kolbenpumpen usw. Zur Änderung der Leistung der Speisepumpen für Senfmahlgänge war es bisher üblich, den Kolbenhub dadurch zu ändern, daß die Kolbenstangenlänge durch ein auf der Mitnehmerstange des Exzenters angeordnetes Handrad, welches dauernd die EXzenterbewegung mitmachte, vergrößert oder verkleinert wurde. Durch die fortwährende Hinundherbewegung des kleinen Handrades veränderte sich selbsttätig der Kolbenhub, wodurch Störungen in der Zuführung der Senfmahlgänge eintraten. Ein weiterer Übelstand war der, daß durch die fortwährende Hinundherbewegung des Handrades eine genaue Einstellung niemals genau getroffen werden konnte und die Bedienung der Verstellvorrichtung mit Gefahren verbunden war. Es ist sehr oft vorgekommen, daß der Bedienungsmann sich zwischen dem Handrad und der Pumpe die Finger gequetscht hat.Device for changing the stroke of piston pumps, etc. To change the performance of the feed pumps for mustard meals, it was previously common to adjust the piston stroke by changing the piston rod length by one on the drive rod the handwheel arranged on the eccentric, which constantly took part in the eccentric movement, enlarged or reduced. Due to the continuous back and forth movement of the small handwheel, the piston stroke changed automatically, causing malfunctions in the feeding of the mustard meals occurred. Another drawback was that through the continual back and forth movement of the handwheel never ensures an exact setting could be taken exactly and the operation of the adjustment device with dangers was connected. It has very often happened that the operator intervenes has crushed your fingers on the handwheel and the pump.

Die vorgeschilderten Mißstände werden bei der neuen Vorrichtung zur Hub- und Leistungsänderung für Senfpumpen dadurch vermieden, daß das Ver stellungshandrad nicht prtsbeweglich ist.The abuses described above are used in the new device Stroke and power change for mustard pumps avoided that the United position handwheel is not prtsmobile.

Die Pumpe wird von einem stoßfrei arbeitenden Exzenter a mittels der Gabelführung b angetrieben. Auf der Kolbenstange d befindet sich innerhalb des Gehäuses c eine Mutter e und ein Stellring f. Die Leistungsänderung der Pumpe g erfolgt in bekannter Weise durch die Längenänderung der Kolbenstange.The pump is driven by a smooth eccentric a by means of the fork guide b . A nut e and an adjusting ring f are located on the piston rod d within the housing C. The change in performance of the pump g takes place in a known manner by changing the length of the piston rod.

Die Längenveränderung der Kolbenstange erfolgt aber, und das wird bei Senfspeisepumpen an Senfmahlgängen als Erfindungsmerkmal angesehen, durch ein nicht ortsbeweglich angeordnetes Verstellrad h.The change in length of the piston rod takes place, and that will regarded as a feature of the invention in mustard feed pumps at mustard meals, by a Adjusting wheel not arranged to be movable h.

Die Wirkungsweise der Hubänderung nach beiliegender Zeichnung ist folgende: Die Verstellung des Gewinderinges e erfolgt durch einfaches Drehen der Kolbenstange d mittels eines nicht ortsbeweglichen Verstellungshandrades h. Ein durch das Verstellungshandrad h laufender Keil, welcher sich fest auf der Kolbenstange d befindet, ermöglicht in jeder Stellung der Kolbenstange ein Mitnehmen derselben durch das Verstellungshandrad h. Ein in einer eingedrehten Rille des Verstellungshandrades h fassendes Winkelstück h, welches auf dem Pumpengehäuse Z befestigt ist, sorgt für eine Vermeidung der hin und her gehenden Bewegung des Verstellungshandrades h entsprechend der Bewegung der Kolbenstange d.The way in which the stroke change works is as shown in the accompanying drawing following: The adjustment of the threaded ring e is done by simply turning the Piston rod d by means of a non-movable adjustment handwheel h. A wedge running through the adjustment handwheel h, which is firmly attached to the piston rod d, allows the piston rod to be taken along in any position through the adjustment handwheel h. One in a screwed-in groove of the adjustment handwheel h holding angle piece h, which is attached to the pump housing Z, ensures to avoid the back and forth movement of the adjustment handwheel h according to the movement of the piston rod d.
