抽真空装置在核电厂一回路中的应用

Application of Vacuum Devices in NPP Primary Loop

核电厂一回路抽真空装置通过水环真空泵,在一回路中产生预设的真空度,并结合重力充水的方式,将蒸汽发生器U型管内的空气赶出,达到一回路充水排气的目的。本套装置的应用较大幅度地提高了一回路充水排气的效率,节约了时间,并能够有效地优化调试进程和大修进程。

Vacuum Devices by liquid ring vacuum pump, resulting in a more appropriate degree of vacuum in a loop, and combined gravitational water-filled way, the air steam generator U-tube out of the reach of a water-filled exhaust loop purpose. By applying this set of devices dramatically increased the primary circuit water-filled exhaust efficiency, save time, and be able to effectively optimize the debugging process and overhaul processes.
