Shilong Station No. 2 spindle flange oil leakage problems in the overhaul of the maximum thrust load on the unit are re-calculation. A series of comprehensive measures of governance are taken by increasing the coupling bolt preload, changing the tensile mode, reducing the non-pressure side of the gap and so on. The approach has a certain validity project.
