在用核岛主泵冷却水系统用软管的安装设计

压水堆核电站需用大量的金属软管,以前依靠国外进口,现要求国产化.由于进口软管与国产软管的产品结构和性能不同,原来的管路安装不能适应国产软管的安装要求,需重新设计.文中采用几何分析方法,推导出了在用核岛U型、S型弯曲安装的软管长度计算公式,并利用已掌握的安装数据,得到了软管的计算长度,但对于安装半径R小于软管最小弯曲半径...

Installation Design of the Flexible Hose for In-service Nuclear Island Cooling Water System Pump

The pressurized water reactor nuclear power plant which requires large amounts of the metal flexible hose.In the past,the use of hoses depended on import.But now,domestic production is required.As imported and domestic hoses have different structures and properties,the original installation method cannot meet the domestic requirements,so the hoses need to be re-designed.This paper used a geometric analysis method to derive the installed length bend hose formula of respectively U-type and S-type for in-servi...
