Title (EN) PRESSURE WASHER DRUM
(FR) TAMBOUR LAVEUR A PRESSION
Abstract:
(EN) In prior pressure washer drums, the filter deck was supported on the central shaft by spokes welded to the central hub which was in turn welded to the shaft. The extreme forces caused premature failure of the welded joints. The present invention provides a pressure washer drum (10) in which sandwiched parallel plates (32) having an array of apertures replace the spokes and central pipe and journals are supported on the hub by a bolting system rather than by welding.
(FR) Dans les tambours laveurs à pression actuels, la paroi cylindrique filtrante est portée par l'arbre central au moyen de rayons soudés au moyeu central soudé à son tour à l'arbre. Les forces extrêmes produites provoquent une défaillance prématurée des soudures. La présente invention concerne un tambour laveur (10) à pression dans lequel des plaques parallèles (32) prises en sandwich ayant une série d'ouvertures remplacent les rayons, et un conduit central ainsi que des tourillons sont portés sur le moyeu par l'intermédiaire d'un système de boulons plutôt que par soudage.
