Title (DE) MEMBRANAUFBAU MIT TRENNSCHNITTEN
(EN) DIAPHRAGM STRUCTURE HAVING SEPARATING CUTS
(FR) STRUCTURE MEMBRANAIRE À ENTAILLES SÉPARATRICES
Abstract:
(DE) Membranaufbau (1) bestehend aus zwei Kunststoffschichten (2, 3) und einem zwischen den beiden Kunststoffschichten (2, 3) angeordneten, aus Fasern oder Drähten bestehenden Flächengebilde (4). Um einen Membranaufbau für Membranpumpen bereitzustellen, welcher sich durch eine verbesserte Widerstandsfähigkeit gegen Brüche der Membran, insbesondere infolge von auftretendem Reibverschleiß, auszeichnet, weist zumindest ein Teil der Fasern oder Drähte des Flächengebildes (4) einen Trennschnitt (6a) auf.
(EN) The invention relates to a diaphragm structure (1) comprising two plastic layers (2, 3) and a fabric (4) consisting of fibers or wires arranged between the two plastic layers (2, 3). In order to provide a diaphragm structure for diaphragm pumps, which diaphragm structure is characterized by an improved resistance to breakages of the diaphragm, in particular as a result of frictional wear that occurs, at least some of the fibers or wires of the fabric (4) have a separating cut (6a).
(FR) L'invention concerne une structure membranaire (1) constituée de deux couches de matière plastique (2, 3) et d'une structure plane (4) constituée de fibres ou de fils agencée entre les deux couches de matière plastique (2, 3). L'invention vise à fournir une structure membranaire pour des pompes à membrane, laquelle se caractérise par une meilleure résistance aux ruptures de la membrane, en particulier suite à l'apparition d'une érosion. À cet effet, au moins une partie des fibres ou des fils de la structure plane (4) présente une entaille séparatrice (6a).
