Abstract
A plugging apparatus for fixing a mechanical plug within a heat transfer tube of a heat exchanger includes a main body capable of being coupled to a tool guide robot movable under remote control inside a water chamber of the heat exchanger, a plug fixing mechanism mounted on the main body for conveying a mechanical plug from outside the heat exchanger and fixing the mechanical plug in the heat transfer tube, and a clamping mechanism for clamping the main body to a tube plate of the heat exchanger at a desired position on the tube plate of the heat exchanger. The invention makes it possible to fix a mechanical plug in a heat transfer tube of a steam generator or heat exchanger of a reactor in a remote-controlled and continuous manner.
