Title (EN) HIGH-PERFORMANCE PLASMA TORCH
(FR) TORCHE À PLASMA HAUTES PERFORMANCES
Abstract:
(EN) A plasma cutting torch comprises: a torch body (2); an electrode (3) mounted in the torch body (2); a nozzle (4) mounted on the proximal end of the torch body (2), surrounding the tip of the electrode (3) to form a chamber (8) where plasma is generated by feeding a first fluid (Fl) into it, and having a first central through hole (9) for the passage of the plasma; a nozzle support or holder (5) whose inside wall faces the outside wall of the nozzle (4) in such a way as to form a first chamber (10) through which a cooling fluid flows; a first unit (6) for covering and protecting the nozzle (4) and the nozzle holder (5); a channel (17), through which a second fluid (F2) flows towards the second hole (16); the torch also comprises a second chamber (18) for the passage of cooling liquid.
(FR) On décrit une torche de découpe à plasma comportant : un corps (2) de torche ; une électrode (3) montée dans le corps (2) de torche ; une buse(4) montée sur l'extrémité proximale du corps (2) de torche, entourant le bout de l'électrode (3) pour former une chambre (8) où un plasma est généré en y introduisant un premier fluide (Fl), et dotée d'un premier trou débouchant central (9) destiné au passage du plasma ; un porte-buse ou support (5) dont la paroi intérieure fait face à la paroi extérieure de la buse (4) de manière à former une première chambre (10) à travers laquelle s'écoule un fluide de refroidissement ; une première unité (6) servant à recouvrir et à protéger la buse (4) et le support (5) de buse ; un conduit (17) à travers lequel un deuxième fluide (F2) s'écoule en direction d'un deuxième trou (16) ; la torche comporte également une deuxième chambre (18) destinée au passage d'un liquide de refroidissement.
