Title (DE) RADIALVENTILATOR MIT DIFFERENZDRUCKMESSUNG
(EN) RADIAL VENTILATOR WITH DIFFERENTIAL PRESSURE MEASUREMENT
(FR) VENTILATEUR RADIAL DOTÉ D’UNE MESURE DE PRESSION DIFFÉRENTIELLE
Abstract:
(DE) Die Erfindung betrifft einen Radialventilator (1) mit einem Ventilatorrad (2), einem das Ventilatorrad antreibenden Motor und einem Ventilatorgehäuse (3), wobei der Radialventilator (1) eine in Strömungsrichtung gesehen ansaugseitige Saugseite (S) und eine axial gegenüberliegende Druckseite (D) aufweist, wobei das Ventilatorgehäuse (3) aus einem saugseitigen Vorderteil (4) und einem druckseitigen Hinterteil (5) gebildet ist, zwischen denen, in Axialrichtung gesehen, das Ventilatorrad (3) angeordnet ist, wobei das Vorderteil (4) und das Hinterteil (5) mit zumindest einer Axialstrebe (6) verbun- den sind, die einen zur Saugseite (S) und zur Druckseite (D) offenen Hohlkanal (7) aufweist, in dem mindestens ein Differenzdrucksensor (8) angeordnet ist, der im Betrieb des Radialventilators (1) unmittelbar einen Druckunterschied des jeweiligen statischen Luftdrucks auf der Saugseite (S) und der Druckseite (D) des Radialventilators (1) erfasst.
(EN) The invention relates to a radial ventilator (1) comprising a ventilator wheel (2), a motor which drives the ventilator wheel, and a ventilator housing (3). The radial ventilator (1) has a suction side (S), which is on the suction side when viewed in the flow direction, and a pressure side (D), which lies axially opposite the suction side. The ventilator housing (3) is made of a suction-side front part (4) and a pressure-side rear part (5), between which the ventilator wheel (3) is arranged when viewed in the axial direction. The front part (4) and the rear part (5) are connected by at least one axial brace (6) that has a hollow channel (7) which is open towards the suction side (S) and the pressure side (D) and in which at least one differential pressure sensor (8) is arranged, said differential pressure sensor directly detecting a pressure difference of the respective static air pressure on the suction side (S) and the pressure side (D) of the radial ventilator (1) during the operation of the radial ventilator (1).
(FR) L’invention concerne un ventilateur radial (1) comportant une roue de ventilateur (2), un moteur entraînant la roue de ventilateur, et un carter de ventilateur (3), le ventilateur radial (1) présentant un côté aspiration (S) côté aspiration vu dans le sens de l’écoulement et un côté pression (D) opposé axialement, le carter de ventilateur (3) étant constitué d’une partie avant (4) côté aspiration et d’une partie arrière (5) côté pression entre lesquelles, vu dans le sens axial, la roue de ventilateur (2) est agencée. La partie avant (4) et la partie arrière (5) sont reliées à au moins une barre axiale (6) qui présente un canal creux (7) ouvert en direction du côté aspiration (S) et en direction du côté pression (D), et dans lequel est agencé au moins un capteur de pression différentielle (8) qui, lorsque le ventilateur radial (1) fonctionne, détecte directement une différence de pression de l’air comprimé statique concerné sur le côté aspiration (S) et sur le côté pression (D) du ventilateur radial (1).
