THE SEALING REPAIR PROCESS FOR THE LEAKS IN THE WATER CLIPS OF WATER COOLED THE STATOR BARS OF THE TURBINE GENERATOR

摘要

Step 1 (S1) as related to the present invention the generator stator winding Water clip sealing portion inner leak repair and, in particular, by injecting the air pressure and then sealed through the filler metal drying jig (301) for checking for leaks; A second step of cutting by using a bend, and shows a portion cutter straight leaf-type water clip (100) (S2); A third step of using the wire brush and the laser beam 403 is free from all oxidation and impurities, washed with acetone (S3); Applying a filler metal (500) for the brazing, and dried with a halogen lamp 302, a fourth step of repeatedly performed until the repair is completed, after a review of the filler metal 500 is applied by a laser beam (403) (S4 ); And the wire was washed with a brush and air pressure being configured to cut a straight leaf-type water clip 100 in a fifth step (S5) of performing a final check for and repair parts to re-joined to the torch or TIG brazing method a, and this invention has very little thermal effect effect due to dry the filler metal the width and depth of the uniform application of the leak defect area between the irregular element wire and the strand, and applied by using a halogen lamp, a laser beam used to melt the filler metal powder has excellent effects on solid maintenance because maintenance leak a seal defect.
