Description

Schlauch für Quetschpumpen In den sog. Schlauch- oder Quetschpumpen sind :elastische Schläuche angeordnet, die durch Verdrängungskörper fortschreitend zusa.mmeiiigequetscht werden, wie dies beispielsweise aus der Abb. i der beiliegenden Zeichnung ersichtlich ist. Die Schläuche von etwa kreisrundem Profil werden von dem Verdrängung skörper b gegen die Unterlage a, gedrückt und zusammengequetscht. Nach dem Weiterrücken des Verdrängungskörpers müssen sie, wenn die Pumpe richtig arbeiten soll, ihre ursprüngliche Gestalt wieder annehmen. Infolge der Dauerquetschbeanspruchung tritt nun eine Ermüdung des Schlauchmaterials ein, die darin besteht, daß die Schläuche in der Zeit der Entlastung durch den Verdrängerkörper b nicht mehr ihre kreisrunde Gestalt annehmen, sondern mehr oder weniger ,elliptisch bleiben.Hose for squeeze pumps The so-called hose or squeeze pumps contain: elastic hoses which are gradually squeezed together by displacement bodies, as can be seen, for example, in Fig. 1 of the accompanying drawing. The hoses with an approximately circular profile are pressed against the base a by the displacement body b and squeezed together. After the displacement body has moved further, if the pump is to work properly, it must return to its original shape. As a result of the permanent squeezing stress, the tube material now becomes fatigued, which consists in the fact that the tubes no longer assume their circular shape during the time of relief by the displacement body b, but rather remain more or less elliptical.

Es wurde nun gefunden, daß man diesen Nachteil vermeiden kann, wenn man in den Schlauch eine Trennwand zwischen den seitlichen Rippen durch Spritzen oder nachträgliches Einvulkanisieren, etwa gemäß Abb.2, anbringt. Diese elastische Trennwand oder Brüche wird immer den Schlauch in die ursprüngliche Form zugelastisch zurückführen.It has now been found that this disadvantage can be avoided if insert a partition into the hose between the side ribs by spraying or subsequent vulcanization, for example as shown in Figure 2. This elastic Partition wall or breaks will always resilient the hose to its original shape lead back.
