摘要
广深沙角B电力有限公司2号汽轮机在大修中将高中压轴封及隔板汽封改为自调整汽封(布莱登汽封),低压末级叶片改为日本东芝公司最新研制的第三代26″(660.4mm)叶片。通过以上改造,汽轮机的经济性和安全性得到显著提高。
The HP and IP shaftpacking and diaphragm glandpacking of steam turbine no.2 in Guangshen Shajiao B Power Co Ltd had been retrofitted into selfregulated glandpacking (Breden glandpacking), and the last stage blades changed into 660.4 mm (26″) blades of third generation newly developed by Toshiba Company of Japan in major repair. Through abovementioned retrofits, the economic behavior and safety of said steam turbine have been obviously enhanced.
