INSTALLATION POUR LE CONTROLE ULTRASONORE DE PIECES, ET DISPOSITIF POUR BALAYER UNE SURFACE DE LA PIECE A CONTROLER

摘要

A probe for carrying out ultrasonic controls on parts comprises a carriage (2) provided with wheels (5) or rollers susceptible of moving while bearing on the part to be controlled (P); an ultrasound emitter-receiver (1) carried by the carriage and of which the active face (10) is turned towards the part to be controlled (P); a sleeve (8) susceptible of sealingly bearing against the surface of the part to be controlled, said sleeve surrounding the active face of the emitter-receiver and forming together with the surface of the part to be controlled a substantially closed chamber intended to contain a liquid for transmission of ultrasounds, the chamber having an annular deaeration space (12, 17) surrounding the active face of the emitter-receiver and being connected to a tank of liquid (14) maintained at a level higher than that of the chamber.
