ELECTROPOLISHING DEVICE OF STEAM GENERATOR CHANNEL HEAD

摘要

PURPOSE: An electropolishing device is provided to electropolish a round shape or a edge part of a channel head inside without entering a narrow space by controlling the electropolishing device remotely. CONSTITUTION: A menu plate(20) is inserted to a manway(12) or a coolant passage(14) of a channel head(10) moving freely. A head is connected to the menu plate hingedly, and is composed of an electrode, an electrolyte nozzle, a washing liquid nozzle and a distance recognizing sensor. A electrolyte supplying device(60) is connected to the electrolyte nozzle and a washing liquid supplying device(70) is connected to the washing liquid nozzle. An electrolyte processing device(80) receives the washing liquid and electrolyte through a receiving pipe. A power supply(100) is connected to the menu plate, the electrolyte supplying device, the washing liquid supplying device and the electrolyte processing device. A remote controller is connected to the power supply controlling the power supply, the menu plate, and the head.
