摘要
由于制造原因,天生桥二级电站5、6号机组中心补气系统的补气管顶部被抬高了60mm,造成密封室无法安装。5号机利用在密封室下方加垫抬高密封室,仅解决了安装问题;6号机采用将进气室整体抬高的方法,不仅解决了安装问题,也改善了运行状况,效果比较理想。
The sealing rooms of the central air admission systems of the No.5 and No.6 turbines cannot be installed because the top parts of vents were lifted 60 mm while manufacturing. Adding a pad at the bottom of the sealing room merely can solve the installation of No.5 turbine. While installing No.6 turbine, the method of lifting the whole air room was adopted, which not only solved the installation problem but also improved the operation conditions.
