本文主要介绍汽轮机抽真空快冷方法,简化汽轮机抽真空快冷时常规送轴封汽源的繁琐。汽缸金属温度下降速度得到了有效的控制,可为电厂检修节约检修工期约4～5天。实践证明汽机抽真空快冷不需要投入更多快冷设备即可达到快速冷却的效果。
This article describes the turbine vacuum pumping fast cooling method to simplify the steam turbine vacuum pump routinely delivered to the gas seal cumbersome. Cylinder metal temperature drop rate has been effectively controlled, for power plant maintenance overhaul maintenance period of about 4 to 5 days. Practice has proved that the vacuum pumping machine fast cooling do not need to put more rapid cooling equipment to achieve the effect of rapid cooling.
