KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Fallrohr der hydraulischen Luftkompressoren kann in vielen Fällen nicht senkrecht, sondern nur in einer schiefen Ebene angeordnet werden. Hierbei zeigt sich nunIn many cases, the downpipe of the hydraulic air compressors cannot be vertical, but can only be arranged in an inclined plane. This now shows
der Übelstand, daß die Luftblasen nicht mehr nach unten mitgerissen werden, sondern sie stauen sich im Fallrohr selbst und bilden Luftsäcke, die sich vom Wasser trennen und nach oben steigen. Dies hat eine wesentlichethe inconvenience that the air bubbles are no longer carried downwards, but them accumulate in the downpipe itself and form air sacs that separate from the water and rise to the top. This has an essential
ίο Verminderung des Wirkungsgrades des Kompressors zur Folge.ίο Reduction in the efficiency of the compressor result.
Um dies zu verhindern, wird nach vorliegender Erfindung eine Einlage- oder ein Steg, der schraubenförmig verdreht ist, in das Fallrohr eingesetzt. Dieser Steg kann entweder auf der ganzen Länge der Leitung oder nur an einzelnen Stellen in die Leitung eingesetzt werden, wie in Fig. 1 gezeigt. α sind die Stege, b der Saugkopf des Kompressors, c das Fallrohr, d die Luftabscheidekammer. To prevent this, according to the present invention, an insert or a web, which is twisted in a helical manner, is inserted into the downpipe. This web can be used either over the entire length of the line or only at individual points in the line, as shown in FIG. α are the webs, b the suction head of the compressor, c the downpipe, d the air separation chamber.
In Fig. 2 bis 5 sind Ausführungsformen der schraubenförmig verdrehten Stege bezw. Rohreinsatzstücke mit solchen Stegen dargestellt. In Fig. 2 und 3 hat der Einsatz a kreuz- oder sternförmigen Querschnitt, in Fig. 4 und 5 ist ein einfacher Steg α, gezeigt.In Fig. 2 to 5 embodiments of the helically twisted webs are BEZW. Tube inserts shown with such webs. In Fig. 2 and 3 the insert a has a cross or star-shaped cross-section, in Fig. 4 and 5 a simple web α is shown.
Die schraubenförmige Verdrehung des Steges bewirkt, daß das Wasser-Luftgemisch in Wirbeln durch das Fallrohr strömt. Hierdurch wird eine innige Mischung von Wasser und Luft und infolgedessen ein sicheres Mitreißen der Luftblasen durch das Wasser bewirkt. Eine Bildung von sich stauenden Luftsäcken ist somit ausgeschlossen.The helical twisting of the web causes the water-air mixture to form eddies flows through the downpipe. This creates an intimate mixture of water and air and consequently a safe entrainment the air bubbles caused by the water. A formation of accumulating air sacs is therefore excluded.
Die Anzahl der Einsätze richtet sich nach den gemachten Erfahrungen nach dem Neigungswinkel des Fallrohres. Je steiler das Fallrohr angeordnet ist, desto weniger Einsätze sind erforderlich, und umgekehrt.The number of uses depends on the experience gained and the angle of inclination of the downpipe. The steeper the downpipe, the fewer uses are required and vice versa.
