TURBINE FOR ULTRASONIC INSPECTION OF HEAT EXCHANGER TUBES

摘要

PURPOSE: A water-logging type turbine for an ultrasonic inspection of a heat exchanger tube is provided to arrange an ultrasonic wave generating unit only in an installation unit of a body, thereby reducing external diameters of the body and a connector. CONSTITUTION: A water-logging type turbine (10) for an ultrasonic inspection of a heat exchanger tube includes a body (100), a connector (200), an ultrasonic wave generating unit (300), an installation unit (400), and a reflection unit (500). An installation space unit is formed inside the body. The connector is connected to a hose (40) in which a coaxial cable (30) is arranged inside. The connector includes a through-hole of a diameter smaller than the installation space unit of the body. The coaxial cable penetrates the through-hole. The connector is connected to the body. The ultrasonic wave generating unit is arranged in the installation space unit of the body and generates ultrasonic waves. The installation unit connects the body and the connector while arranging the ultrasonic wave generating unit on the installation unit of the body. The reflection unit reflects the ultrasonic waves generated in the ultrasonic wave generating unit to inner and outer walls of the heat exchanger tube.
