Description

In dem Patent 95,8.3:,57 wird eine Zentrifugal-Jauchepunipe beschrieben, die zusammenwirkend mit einer Drehkolbenpumpe mit gemeinsamer Welle es möglich macht, die Jauche selbst anzusaugen und zu fördern. Die Drehkolbenpumpe arbeitet in diesem Falle als Entlüftungspumpe, so daß die Jauche in die Zentrifugal-Jauchepumpe gesaugt wird und dann durch diese gefördert wird. Um nun die luftansaugende Pumpe vor dem Eindringen der Jauche zu schützen, ist ein Schwimmer angeordnet, welcher nach dem Ansaugen den Entlüftungskanal absperrt.In the patent 95,8.3:, 57 a centrifugal manure pipe is described, which, working together with a rotary lobe pump with a common shaft, makes it possible to suck in the liquid manure and to convey it. The rotary lobe pump works in this Trap as a vent pump so that the slurry is sucked into the centrifugal slurry pump and is then promoted by them. Now to the air-sucking pump before the To protect the penetration of the liquid manure, a float is arranged, which after the Suction blocks the ventilation duct.

Es ist nun vielmals sehr von Vorteil, wenn ein rasches Ansaugen möglich ist. Dadurch wird die Entlüftungspumpe geschont und die Wartezeit zum Pumpen verkürzt. Dies ist jedoch nur möglich, wenn der eigentliche Saugraum vor dem Zentrifugalpumpenkreisel direkt entlüftet wird. Es ist dies damit erreicht, daß der Entlüftungskanal durch die gebohrte Welle weitergeführt wird. In diesem Falle ist statt des Schwimmers ein durch Schwerkraft oder Federkraft wirkendes Ventil dazwischengeschaltet. Wenn die Ansaugöffnung nicht direkt in das Mittel der Welle geführt wird, sondern durch einen Seitenkanal, ist auch der Vorteil gegeben, daß Schmutzteile abgeschleudert werden und somit die Gefahr des Verstopfens des Entlüftungskanals behoben wird. Zur weiteren Sicherung sind noch Siebe an der Welle und innerhalb des Entlüftungskanals vor dem Ventil vorgesehen.It is often very advantageous if rapid suction is possible is. This protects the priming pump and shortens the waiting time for pumping. However, this is only possible if the actual suction chamber is in front of the centrifugal pump is vented directly. This is achieved by the ventilation duct through the drilled shaft is continued. In this case, instead of the swimmer a valve acting by gravity or spring force is interposed. if the suction opening is not guided directly into the center of the shaft, but through a side channel, there is also the advantage that dirt particles are thrown off and thus the risk of clogging of the vent channel is eliminated. There are also sieves on the shaft and inside the ventilation duct for further protection provided in front of the valve.

In der Zeichnung sind verschiedene Ausführungen dargestellt. Abb. i macht den -Längsschnitt der gesamten Pumpe, Abb.4 denselben teilweise ersichtlich; Abb. 2 dagegen zeigt die Pumpe der Abb. 4 in Vorderansicht und Schnitt A-B; Abb.3 zeigt einen vergrößerten Ausschnitt der Pumpe nach Abb. i und Abb. 5 das gleiche der Pumpenausführung nach Abb. 4.Various designs are shown in the drawing. Fig. i shows the longitudinal section of the entire pump, Fig.4, the same partially visible; Fig. 2, however, shows the pump of Fig. 4 in front view and section A-B; Fig 3 shows an enlarged section of the pump according to Fig. i and Fig. 5 the same the pump version according to Fig. 4.

Die Pumpenteile haben folgende Bezeichnungen: Der Zentrifugalpumpenkreisel a, das Pumpengehäuse b, die Kreisel- oder Drehkolbenwelle e, der Drehkolben f, die Entnahmeöffnung mit dem Schnellverschluß q, das Entlüftungsventil zu und die Siebanordnung p1 und p2, die Entlüftungskanäle in der Welle r, s, t sowie der Ringkanal 2t und der Verbindungskanal v und na. The pump parts have the following designations: the centrifugal pump rotor a, the pump housing b, the centrifugal or rotary piston shaft e, the rotary piston f, the extraction opening with the quick-release fastener q, the vent valve closed and the sieve arrangement p1 and p2, the vent channels in the shaft r, see , t as well as the ring channel 2t and the connecting channel v and na.

Der Ringkanal kann durch eine entsprechende Eindrehung in die Welle oder einer Aussparung im Lager gebildet sein.The ring channel can be screwed into the shaft accordingly or a recess in the bearing.
