某发电厂的ХТГЭК-300-240汽轮机组(2号机)在检修前(安装后)运行了一年四月。在检修过程中发现高中压转子严重偏心。考虑到高中压部分情况良好,且检修人员严重不足,采用了不揭开高中压缸校中心,缩短工期的检修方法。高中压转子的半接轴器向下张口0.6毫米,而记录值为0.35-0.38毫米。偏心这样大,但又不能采用熟知的,在检修中常用的校中心法,即抽掉一些垫片,放低1号轴承和高压缸出
The ХТГЭК-300-240 turbine unit (Unit 2) of a power plant operated April (April) before overhaul (after installation). In the overhaul of high-pressure rotor found serious eccentric. Taking into account part of the high pressure in good condition, and a serious shortage of maintenance personnel, using not open the middle school cylinder pressure cylinder center, shorten the duration of the maintenance methods. The half-coupler of the high-medium-pressure rotor had a downward opening of 0.6 mm and a recorded value of 0.35-0.38 mm. Eccentricity is so big, but can not use well-known school-center method commonly used in overhaul, that is, take out some gaskets, lower the No. 1 bearing and high-pressure cylinder out
