bei verschieden habe« Niveau dar Stempelflachen nicht sprunghaft, sondern stetig diesen Niveauändarungen folgen·with different, the level of the stamp surfaces is not erratic, but rather constantly follow these level changes

Anhand der Figur wird ein Auefübrungsbsispial näher erläutert* 1 stellt die an sich bekannte Schlauchpumpe dar« bei welcher bspw. über pine Nockenwelle ein Ansahl Stempel 10 periodisch gesenkt und gehoben werden. Ein oder »ehrer» hintereinanderliegende Schläuche 2» die in einen» Schleuehbatt 3 eingebettet sind» werden dadurch en bestimmten Stellen zu* aemmsngsquetecht. Durch geeignet* Ausbildung der Stempelbewegung wird dabei dar Schlauchinhalt kontinuierlich nach einer 5eita ausgepresst· Die Schläuche 2 sind in Schlauchkupplungen 4, S gefasst« an welche wieder Zu- und Ableitungen 6, 7 angeschlossen sind. Erfindungegamäee ist nun zwischen die Stempel IQ und dia Schläuche 2 eine Materialachieht 8 eingelegt, die einerseits am Putnpengehäuea mit einer Befestigung 9 fixiert und anderseits en einer Teder 20 nachgiebig gehalten iat. Als Werkstoff füs die Materialechieht 8 hat sich glasfaserverstärktes Tafion in einer Schichtdicke von Q,2mm · 1,5mm bewährt. Durch diese Zwiachenlage konnte die Lebenadeuar der Pumpenschläuche von ureprUnglieh 400 Betriebsstunden auf 2000 Betriebeetunden erhöht werden,With the aid of the figure, a training program is explained in more detail * 1 shows the hose pump known per se, in which, for example, an Ansahl punch 10 is periodically lowered and raised via a pin camshaft. One or more hoses 2 lying one behind the other, which are embedded in a “Schleuehbatt 3”, are thereby made secure in certain places. By appropriately designing the stamp movement, the hose contents are continuously squeezed out according to a direction. Erfindungegamäee is now sandwiched between the stamp and IQ dia hoses 2 is a Materialachieht 8, on the one hand fixed to the Putnpengehäuea with an attachment 9 on the other hand a Teder en iat 20 resiliently held. Glass fiber reinforced Tafion in a layer thickness of Q.2mm · 1.5mm has proven itself as the material for the material material 8. Due to this situation, the life span of ureprUnglieh's pump hoses could be increased from 400 operating hours to 2000 operating hours,

bia dia Schläuche infolge dar Walkarbeit defekt wurden.bia dia hoses were defective as a result of flexing.
