一种核电厂立式蒸汽发生器U型传热管单管动态特性试验装置
摘要：
本发明提供一种核电厂立式蒸汽发生器U型传热管单管动态特性试验装置，其包括传热管、底部支承、中间支承、底座和加载装置；所述传热管的两端通过所述底部支承固定，所述传热管束的两端之间通过所述中间支承支撑；所述传热管束分为两段直管段和一段圆弧段，两段所述直管段分别与所述圆弧段的两端连接，圆弧段通过所述加载装置施加载荷；所述传热管采用最大弯曲半径的传热管。本发明提供的核电厂立式蒸汽发生器U型传热管单管动态特性试验装置，可以完成单管动态特性试验，从而获得影响传热管单管动态特性的因素。
摘要（英）：

The invention provides a U-shaped heat transfer tube single-tube dynamic characteristic test device for a vertical steam generator of a nuclear power plant. The device includes a heat transfer tube, bottom supports, middle supports, bases and loading devices. The two ends of the heat transfer tube are fixed by the bottom supports. The part between the two ends of the heat transfer tube bundle is supported by the middle supports. The heat transfer tube bundle has two straight tube sections and an arc section. The two straight tube sections are connected to the two ends of the arc section. The arc section is loaded by the loading device. The heat transfer tube adopts a heat transfer tube with a maximum bending radius. The U-shaped heat transfer tube single-tube dynamic characteristic test device for a vertical steam generator of a nuclear power plant provided by the invention can complete a single-tube dynamic characteristic test, thereby obtaining factors affecting dynamic characteristics of a single tube of the heat transfer tube.
