摘　　要：在修理上世纪90年代俄罗斯制造的发电用АД-31СТ燃气轮机时,发现该燃气轮机80%左右的中央传动供油孔存在不同程度的磨损,且随着使用时间的增长磨损逐渐增加,进而导致密封失效后滑油泄露,影响燃气轮机的安全和可靠工作。因缺乏设计资料和修理技术文件,对其结构进行重新研究,并对密封结构进行设计计算,找出了易发生滑油泄露的磨损量值,制订了加衬套进行修复的工艺方法。In 1998 Russian - made repair with AД - 31CT gas turbine power generation, it was found that the gas turbine drives a central hole of about 80 percent of the oil supply varying degrees of wear and tear, and with the growth in the use of time - worn gradually increased, leading to seal failure after the oil leak, the impact of safe and reliable operation of the gas turbine. Due to lack of design information and repair technical documentation, re-examine its structure, and the sealing structure design calculations to find the oil leak prone to wear magnitude, developed a process for adding bushes were re- paired.
