Description
Pumpe Durch Patent 482 827 ist bereits; Mine Pumpe geschützt, weiche aus einem flachen Hohlkörper von verhältnismäßig großer Länge besteht, welcher an einem Ende fest eingespannt und an die Förderleitung zwischen. zwei Ventilen angieschlossen ist, während. das andere verschlossene Ende unter dem Einfluß einer mechanischen Steuerung steht. Während des Betriebes der Pumpe erfährt der flache Hohlkörper eine mehr oder minder große Krümmung seiner Wandungen, so daß sich das in ihm enthaltene Volumen zufolge der sich an ihm ergebenden Querschnil;tsveränderung erhöht oder verringert, wodurch sich die Pumpwirkung ergibt. Versuche haben nun gezeigt, daß bei der stärkeren Bea,nspruchung, die insbesondere die stärker gekrümmfie Wandung erfährt, fliese bei Überanstrengung dazu neigt, sich. auszubiegen, so, daß Beulen entstehen. Diese bilden dann meist bleibende Formveränderungen, wodurch das einwandfreie Wirken der Pumpe in Frage gestellt wird, da dann die Querschnittsveränderung über die ganze Rohrlänge nicht mehr mit der Vollkommenheit stattfindet, wie dies vorher der Fall war. Es wird daher mach der Erfindung vorgeschlagen"diesien stärker gekrümmten Teil des Hohlkörpers. besonders zu versteifen. Dies kann derart geschehen, daß an ihm eine zusätzliche, verstärkende Rippe vorgesehen wird, welche ientweder mit dem Rohr selbst fest verbunden seist kann, oder auch nur so .geordnet werden braucht, daß sie sich :straff an die Wandungen desselben anlegt.Pump By patent 482,827 is already; Mine pump protected, soft consists of a flat hollow body of relatively great length, which at firmly clamped at one end and attached to the delivery line between. two valves connected is while. the other closed end under the influence of a mechanical one Control stands. During the operation of the pump, the flat hollow body experiences a more or less great curvature of its walls, so that that contained in it Volume increased or increased according to the resulting change in cross-section reduced, resulting in the pumping action. Experiments have now shown that with the heavier loads, especially the more curved walls learns tile when overexertion tends to become. bend out so that bumps develop. These then usually form permanent changes in shape, which makes the perfect Effect of the pump is called into question, since then the cross-section changes over the whole length of the pipe no longer takes place with perfection, as it did before was the case. It is therefore suggested that the invention should "be more curved Part of the hollow body. especially to stiffen. This can be done in such a way that at him an additional, reinforcing rib is provided, which i either with the The pipe itself can be firmly connected, or just needs to be arranged that it: rests tightly against the walls of the same.
Ein Ausführungsbeispiel der Erfindung ist in der Abbildung der Zeichnung dargestellt. In dieser bedeutet ,a den Hohlkörper von flachem Querschnitt, welcher in der eingangs erwähnten Weise die eigentliche Arbeitskamm:er der Pumpe bildet. b ist die verstä,rkende Rippe, welche an der stärker gekrümmten Wandung angeordnet "ist.An embodiment of the invention is shown in the figure of the drawing shown. In this, a means the hollow body of flat cross-section, which in the manner mentioned at the beginning, the actual working comb: it forms the pump. b is the reinforcing rib, which is arranged on the more curved wall "is.
Die Überlegung :ergibt, daß auf diese Weise einem Ausbeulen durch Knicken des Baustoffes vorgebeugt wird.The consideration: it results in a bulging through this way Kinking of the building material is prevented.
