摘要
燃气轮机在停机之后要保持于盘车方式,时间为24h,该阶段被称作"冷却盘车",用于保证燃气轮机的均匀冷却,并可以防止缸体变形和转子的弯曲。经过24h连续盘车后,燃气轮机随时在盘车状态下重新启动。在"冷却盘车"已完成后,燃气轮机进入"间歇盘车"运行模式,该模式中转子每6h简短地转动一次以检查轴是否能自由转动。
The gas turbine to keep on turning in the stop after the time of 24 hours, this stage is called ＂cooling turn-ing＂, to ensure uniform cooling of gas turbine, and can prevent the bending deformation of the cylinder and the rotor.After 24 hours of continuous turning, gas turbine always restart in turning state. In the ＂cooling turning＂ has beencompleted, the gas turbine into ＂intermittent turning＂ mode, in this mode, the rotor is briefly rotated every 6 hours tocheck whether the shaft can rotate freely.
