    摘要： A wet-running centrifugal pump includes an electric motor (1) and a centrifugal pump (7) which is driven thereby. The electric motor (1) has a rotor (4) which is rotatably arranged within the stator (3). A canned pot (13), which carries a motor-side bearing for the rotor (4), is provided between the rotor and the stator. Moreover, a bearing plate (19) is provided, which carries a pump-side bearing for the rotor (4), wherein the bearing plate (19) is fixed on the housing side, and in the region of the pump-side bearing immerses into the canned pot. A radial seal (20) is provided between the bearing plate (19) and the canned pot (13).

    摘要： A rotor for an electric motor includes a metal core, a plurality of electrical conductors arranged on the metal core, and a metallic corrosion protection layer enveloping the metal core and the plurality of conductors. The corrosion protection layer is laid as a solid body around the metal core and the conductors and fastened at least to the metal core. The corrosion protection layer is at least a part of a hot-pressing containment for isostatic pressing of the conductors in the metal core.

    摘要： Electric motor driven pump units, especially suited for pumping liquefied gases, including cryogenic fluids, which are lubricated, cooled and balanced with small amounts of fluid pumped by the unit (pumpage), such as 1 to 3 percent of the designed flow capacity of the pump. These small amounts of pumpage are divided into a major flow path through the most heated portions of the units discharging on the pressure side of the pump and a minor flow path through a thrust bearing for the unit and then through the lesser heated portions to discharge on the intake side of the pump. The major flow path, receiving about 75 percent of the lubricating pumpage, is downwardly through the motor shaft radial bearings and rotor compartment to an impeller and a pumping or collection chamber. The minor flow path, receiving about 25 percent of the lubricating pumpage, is through variable thrust bearing orifices tending to raise the motor shaft and carry the axial load of the unit on a thin film discharging through the hollow interior of the shaft to the pump inlet. The pumpage in the major flow path is maintained under pressure and will not boil even when appreciably heated. The minor flow path picks up very little heat and is primarily for balancing the axial thrust load on the shaft.
