    • An article passing rotary seal for a fluid pressurized pipeline, comprises a casing having a cylindrical cavity with a driven rotor rotatably mounted in the cylindrical cavity. The casing has a tangential inlet and tangential outlet to the cylindrical cavity and the rotor has radial arms in sliding contact with the curved surface of the cavity. Articles, e.g. spheres or cylinders of sulphur or coal are passed, by an article feed, one at a time into positions between the rotor blades and carried by them to the outlet, a pump sucks fluid, e.g. water from near the casing inlet and delivers it to near the casing outlet to assist articles entering and leaving the casing. The rotor has an equal number of radial arms sealing each side of the casing between the inlet and outlet to be pressure balanced.
    • 用于流体加压管道的通过旋转密封件的物品包括具有圆柱形腔体的壳体,其中可旋转地安装在圆柱形空腔中的从动转子。 壳体具有与圆柱形空腔相切的入口和切向出口,并且转子具有与空腔的曲面滑动接触的径向臂。 文章,例如 硫或煤的球体或圆筒通过物品进料一次一个地进入转子叶片之间的位置并由它们运送到出口,泵吸入流体,例如流体。 水从套管入口附近,并将其输送到套管出口附近,以帮助进入和离开套管的物品。 转子具有相等数量的径向臂,密封壳体的入口和出口之间的每一侧以进行压力平衡。
