ULTRASONIC TESTING APPARATUS FOR STEAM GENERATOR TUBE

摘要

PURPOSE: An ultrasonic testing apparatus for a steam generator tube is provided to easily replace an ultrasonic probe with an ultrasonic sensor connector protection tube which is screwed with an upper end of a universal joint between a main machine and an ultrasonic probe. CONSTITUTION: Provided is an ultrasonic sensor which transmits and receives an ultrasonic wave in an ultrasonic probe(300). A slip ring is connected to a screw unit to which a probe connection stick is offered. A motor unit is connected to the slip ring through a bent part to drive the ultrasonic probe in spirals. A main machine(500) is connected to the screw unit to which the probe connection stick is offered A rotary shaft is connected through the motor unit and the slip ring. An auxiliary tool part(600) supplies and seals an ultrasonic wave contact medium.
