GEBRÜDER SULZERBROTHERS SULZER

.Die vorliegende Erfindung betrifft eine Einrichtung zur Kühlung der Lager von Rotationspumpen und ist gekennzeichnet durch zwei um das Traglager und um das den Achsialschub der Welle aufnehmende Lager angeordnete, miteinander verbundene Kühlräume, in die das Wasser aus dem Pumpendruckraum um die Welle herum, die in der Zwischenwand mit Spiel rotiert, hineingelangt.The present invention relates to a device for cooling the bearings of Rotary pumps and is characterized by two around the support bearing and around the Axial thrust of the shaft are arranged, interconnected cooling chambers, in which the water from the pump pressure chamber around the shaft that is in the Partition wall rotates with play, got inside

ίο und aus denen es nach Umspülung des letztgenannten Lagers durch eine Leitung abgeführt wird.ίο and from which it is after washing the latter Camp is discharged through a pipe.

Durch diese Anordnung werden nicht allein die bisher üblichen äußeren Umführungsleitungen für das Kühlwasser umgangen, sondern auch vor allem noch der große Vorteil gewonnen, daß zwischen dem das Lager umgebenden Kühlraum und dem Pumpendruckraum Reibung verursachende Stopfbüchsen oder dergl. gänzlich vermieden werden können.This arrangement does not only remove the previously customary external bypass lines bypassed for the cooling water, but also gained the great advantage that between which the camp surrounding cooling chamber and the pump pressure chamber causing friction Or the like. Can be avoided entirely.

Die Erfindung ist auf der beiliegenden Zeichnung in einem Ausführungsbeispiel veranschaulicht. The invention is illustrated in an exemplary embodiment on the accompanying drawing.

Fig. ι zeigt einen Längsschnitt durch das Lager,Fig. Ι shows a longitudinal section through the camp,

Fig. 2 einen Schnitt nach der Linie A-B der Fig. 1,FIG. 2 shows a section along the line AB in FIG. 1,

Fig. 3 einen Schnitt nach der Linie C-D. 3 shows a section along the line CD.

Der Druckraum der Pumpe ist mit α bezeichnet, der Hauptkühlraum mit b, die Pumpenwelle mit c. The pressure chamber of the pump is designated with α , the main cooling chamber with b, the pump shaft with c.

Das den Achsialschub aufnehmende Lager d ist von einem Kühlraum e umgeben, der durch den Kanal/ mit dem Raum b in Verbindung steht. Für das Traglager, das durch die in der Gehäusewand angebrachte Öffnung k von außen zugänglich ist, ist eine Ringschmierung, bestehend aus den beiden Ringen g, die in das Öl im Raum h eintauchen, angeordnet. The bearing d , which absorbs the axial thrust, is surrounded by a cooling space e , which is in communication with the space b through the channel /. For the support bearing, which is accessible from the outside through the opening k made in the housing wall, a ring lubrication consisting of the two rings g, which are immersed in the oil in space h , is arranged.

Das um die Welle c herum in den Raum b durchsickernde Wasser wird von hier über den Raum e durch die Leitung i abgeführt. ...The water seeping through around shaft c into space b is discharged from here via space e through line i . ...

Claims (1)

Patent-Anspruch:Patent claim: Kühlvorrichtung für die Lager von Kreiselpumpen mit einem zwischen dem Lager und dem Pumpendruckraum angeordneten besonderen Raum, in den das Wasser aus dem Pumpendruckraum um die in der Zwischenwand mit Spiel rotierende Welle herum hineingelangt, dadurch gekennzeichnet, daß das Wasser aus dem besonderen Raum (b) durch eine Verstärkung (f) des Lagergehäuses an einem von außen zugänglichen Ringschmieriager vorbei nach einem ringförmigen Raum (e) geführt wird, der das hinter dem Ringschmierlager angeordnete, den Achsialschub aufnehmende Lager (d) umgibt.Cooling device for the bearings of centrifugal pumps with a special space arranged between the bearing and the pump pressure space, into which the water from the pump pressure space reaches around the shaft rotating with play in the partition, characterized in that the water from the special space (b) is guided through a reinforcement (f) of the bearing housing past an externally accessible ring lubrication bearing to an annular space (e) which surrounds the bearing (d) which is arranged behind the ring lubrication bearing and which absorbs the axial thrust.
