Abstract

L'invention se rapporte à un élément permettant d'étanchéifier la surface radiale interne (7) d'une flasque (3) de plaque de serrage au moyen d'un joint (6) statorique présentant une face composée d'un matériau (21) pouvant être usé par frottement. De tels matériaux comprennent, entre autres, des matériaux céramiques de faible densité tels que la brique réfractaire, un matériau polymère sous forme de mousse (à alvéoles ouverts ou fermés) ou à mailles, ou une structure alvéolaire métallique. Les dispositifs d'étanchéité de l'invention minimisent les effets d'un dégagement d'entrée radial et peuvent être utilisés dans une grande variété de soufflantes centrifuges, y compris des soufflantes industrielles de grande dimension.
