本发明解决上述问题，而提出的一种可靠的反应堆用循环泵，泵结构简单，运行安全可靠，无泄漏，专门为高密度介质和高温液体使用。泵进口和水力部分全部覆沫在高温液态金属中。选用合金材料强度在高温下安全可靠，可运用到不同的高温液体场所。
本发明提供一种铅基反应堆用循环泵，包括：
电机，用于带动泵壳内轴连器轴水力部件转动，所述电机通过电机上部分安装的编码器，检测电机振动和角动量，来让泵安全稳定可靠在稳态下长时间工作。
冷却腔，电机内部用机油冷却传动轴传导过来的的热量，同时在一定温度下起到润滑保护作用。
泵壳，泵壳内设有轴承，传动轴和水力部件。电机下面安装有实心轴，贯穿电机，下端插入到泵壳内与水力部件叶轮相接，所述泵壳外壁上设有泵介质进口、底部设有泵介质出口。
作为优化手段，所述实心轴漏出电机上端部分用机械轴承封进行密封，轴承定期打入高温润滑脂，实心轴最上端安装编码器。
作为进一步地优化手段，所述热屏结构与所述电机冷却腔之间设有电机隔热腔。
作为进一步地优化手段，所述实心轴冷却系统设有油冷高压强制循环系统，通入高压冷却介质强制循环带走轴承和密封圈内的热量。

(001)编码器、(002)电机、(003)轴连器、(004)冷却介质入口、(005)冷却腔、(006)冷却介质出口、(007)实心传动轴、(008)泵壳介质入口、(009)水力部件叶轮、(010)支撑轴承、(011)泵壳介质出口，(012)观察口、(013)隔热腔、(014)安装法兰。
具体实施方式
下面结合附图1对本发明作进一步详细描述：
本发明的一种铅基反应堆用循环泵，包括：
电机(002)带动轴连器(003)通过实心传动轴(007)让水力部件叶轮转动。
所述电机通过电机(002)上部分安装的编码器(001)，检测电机转速扭矩振动和角动量，通过数据让泵安全稳定在稳态下长时间工作。
所述电机(002)与冷却腔之(005)之间设有电机隔热腔(013)防止热量通过壳体和实心传动轴(007)传入热量，把温度控制在安全范围。
所述冷却腔(005)主要把实心传动轴(007)和泵壳所传导的热量通过冷却介质入口(004)流入冷却介质，换热后通过冷却介质出口(006)排出。冷缺介质采用机油冷却同时给轴封和密封圈起到降温润滑作用。
所述泵壳内实心传动轴(007)带动，水力部件叶轮(009)旋转，使腔体内部形成负压，泵壳介质入口(008)吸入高温高密度液态金属介质，通过泵壳介质出口(011)排出。让上部高温介质与下部较低温度介质进行充分混合，通过这种强对流混合，可使高温介质传热效率提高，减少温度梯度和温度分层，从而提高换热效率调节堆芯温度。
上述一种铅基反应堆用循环泵，结构简单，可靠性高，无泄露，特别适合输送高温介质，部件全部浸没在高温介质中，全部部件中子辐照和射线工况下可以稳态运行。
