| Abstract: | During repair period of feed-water pumps for units in the first-phase project of Huaneng Fuzhou Power Plant,the chronium-plating repair technology had been adopted for the main shafts of said pumps.After repair,abnormal fluctuation phenomenon of shaft vibration has occurred in trial operation of the feed-water pumps.For this,the shaft of pumps has been chronium-plated again on the basis of test.After chronium-plating,the indication of vibration measurement for pumps' shaft is normal. |
