叙述了利用数学模型对核电站K-1000-60/1500型大功率湿蒸汽轮机机动性指标和停机冷却状态的研究结果。研讨了通过破坏真空进行自然冷却、通过供汽给轴端汽封腔室使之保持24小时真空(停机后)进行自然冷却以及通过中断高、中压缸支持轴承供油使之紧急停机进行汽缸冷却等方案。同时也
The results of research on the maneuverability index and shutdown cooling status of K-1000-60 / 1500 high-power wet steam turbine of nuclear power plant by using mathematical model are described. Natural cooling by destroying the vacuum was discussed and natural cooling was performed by supplying steam to the shaft-end gland chamber for 24 hours under vacuum (after stoppage) and emergency stop by stopping the supply of oil from the high and medium pressure cylinder support bearings Cooling and other programs.
