摘要：
A variable level suction device used in conjunction with a transfer pump which transfers high-level radioactive liquid waste from a waste tank. The variable level suction device comprises an hydraulic housing and a telescoping pipe assembly comprising several pipe sections and mounted alongside the support column of the transfer pump. The telescoping innermost pipe section has a suction inlet, and the outermost telescoping pipe section is welded to the hydraulic housing which encloses an impeller assembly of either a submersible canned motor transfer pump or a lineshaft transfer pump. Suction ports in the hydraulic housing are located adjacent to the impeller assembly. Selective operation of the suction ports and the telescoping pipe sections allows the liquid waste to be suctioned either from the bottom of the waste tank or from a selected level in the waste tank between a free surface and a level near the suction inlet of the innermost pipe section of the telescoping pipe assembly.
摘要（中）：
一种可变水平抽吸装置，与传输泵一起使用，传输泵可从废物罐中传输高放射性废液。 可变水平抽吸装置包括液压外壳和包括几个管段并且与传输泵的支撑柱并排安装的伸缩管组件。 伸缩最内侧的管段具有吸入口，并且最外侧的伸缩管段焊接至液压壳体，该液压壳体包围潜水式密封马达输送泵或主轴输送泵的叶轮组件。 液压外壳中的吸入口位于叶轮组件附近。 吸入口和伸缩管段的选择性操作允许液体废物从废液箱的底部或从废液箱中的自由表面和最靠近最内管的吸入口附近的液位之间的选定液位被吸入 伸缩管组件的截面。
