摘要
烟气轮机一般采用梳齿密封,其密封效果不甚理想。常常导致气封片和转子磨损、润滑油乳化等问题,危及机组安全。广州分公司催化裂化装置YL-7000A烟气轮机将原有的梳齿密封改造为蜂窝阻尼密封,彻底解决了烟气泄漏的问题。该机组改造以来,已连续运行近一年,改造效果令人满意。
Labyrinth seal is the common type used in flue gas turbine,and its sealing effect is not ideal.Such seal often results in abrasion of gas sealing and rotor,the emulsification of lubricant which endangers the safety of the unit. SINOPEC Guangzhou Branch reformed the former labyrinth seal in the YL-7000A flue gas turbine in catalytic cracking unit into honeycomb damping seal and completely resolved the leakage problem of flue gas.The unit has been continuously running for nearly one year since the reformation and the effect is satisfactory.
