摘要： Pressurized lubricant is used for stabilizing shaft bearings in an electrical submersible pump motor. A lubricant pump is located within the motor housing. The lubricant pump has a set of impellers attached to a lower end of the shaft and rotating with the shaft, the impellers being located in the flow path of the lubricant. A diffuser is located upstream of and adjacent each impeller. The impellers increase the radial velocity of the lubricant, and this velocity is converted into a pressure head at the impeller outlet. The lubricant flows through the first diffuser, through the first impeller, through the second diffuser, and then flows through the second impeller and out into a reservoir. The shaft has an axial flow passage with an outlet at each bearing. The outlet has at least three ports arranged symmetrically around the shaft for discharging lubricant into a clearance between the shaft and bearing to create a fluid film.

摘要翻译： 加压润滑剂用于在潜水泵电机中稳定轴承。 润滑泵位于电动机壳体内。 润滑剂泵具有一组叶片，其连接到轴的下端并与轴一起旋转，叶轮位于润滑剂的流动路径中。 扩散器位于每个叶轮的上游并邻近每个叶轮。 叶轮增加润滑剂的径向速度，并且该速度在叶轮出口处被转换成压头。 润滑剂通过第一扩散器通过第一叶轮流过第二扩散器，然后流过第二叶轮并流入储存器。 轴具有在每个轴承处具有出口的轴向流动通道。 出口具有至少三个端口对称地布置在轴上，用于将润滑剂排出到轴和轴承之间的间隙中以产生流体膜。

摘要： An electric motor has a housing with a plurality of stator discs. The discs have slots that align with one another, forming passages. A dielectric film tube inserts into the slots, each of the tubes having a continuous circumference. Each tube has a nonmeltable dielectric film layer of high temperature insulation. The dielectric film layer has overlapping edges and is bonded to a carrier layer of a meltable material. The tubes may be inserted into the slot passages by drawing a vacuum in the interior of each tube, causing it to collapse so that it can be readily inserted.
