Entlastungsvorrichtung an Schleuderpumpen.
Die Erfindung betrifft die bekannten Entlastungsvorrichtungen, bei denen der die Entlastung bewirkende Rotationskörper mit einem feststehenden Teil der Pumpe einen am
EMI1.1
Rotationskörpers geöffnet oder geschlossen werden kann.
Das Wesen der Erfindung besteht darin, dass der Ringraum mit dem Pumpendruckraum verbunden ist. so dass die in letzterem stattfindenden Druckschwankungen die ent- sprechenden Verschiebungen des Rotationskörpers selbsttätig bewirken, um den Achsialdruck auszugleichen.
Die Zeichnung stellt die Erfindung in einem Ausführungsbeispiel dar, u. zw. zeigt Fig. 1 einen Längsschnitt durch die Entlastungsvorrichtung und Fig. 2 eine zweite Ausführungsform eines Details.

dessen Menge wieder abhängig ist von dem im Raum d herrschenden Druck. Die Stellung des Rotationskörpers i entspricht somit dem im Raum d herrschenden Druck.
Bei der gezeichneten Anordnung des Rotationskörpers ergibt sich weiter der Vorteil. dass für die grosse Entlastungsfläche des Rotationskörpers i nur ein Wasserverlust entsprechend dem Durchmesser des kleinen Zylinders m in Betracht kommt.
Das die Entlastung hervorbringende Wasser kann anstatt um den Zylinder m herum auch, wie punktiert angedeutet, durch eine Leitung p oder r beliebiger Art in den Haum k eingeführt werden : auch kann der Rotationskörper statt direkt an der Aussenseite der den Pumpendruckraum begrenzenden Wand, weiter am Ende der Welle angebracht sein.

Relief device on centrifugal pumps.
The invention relates to the known relief devices, in which the relief effecting rotary body with a fixed part of the pump on
EMI1.1
Rotary body can be opened or closed.
The essence of the invention is that the annular space is connected to the pump pressure space. so that the pressure fluctuations taking place in the latter automatically cause the corresponding displacements of the rotating body to compensate for the axial pressure.
The drawing illustrates the invention in one embodiment, u. Between FIG. 1 shows a longitudinal section through the relief device and FIG. 2 shows a second embodiment of a detail.

which they are conical.
I) the water comes out of the pressure chamber d of the pump by seeping through between the cylindrical part m of the rotating body i and the hole in the wall f
EMI1.3
the water can also be used to cool the warehouse.
The gap between surfaces g and h is automatically set close to the menpe
EMI1.4
the amount of which is dependent on the pressure prevailing in space d. The position of the rotary body i thus corresponds to the pressure prevailing in space d.
The illustrated arrangement of the rotating body also has the advantage. that only a water loss corresponding to the diameter of the small cylinder m comes into consideration for the large relief area of the body of revolution i.
The water producing the relief can instead of around the cylinder m also, as indicated by dotted lines, be introduced into the head k through a line p or r of any kind: instead of directly on the outside of the wall delimiting the pump pressure chamber, the rotating body can also continue on the Be attached to the end of the shaft.
