摘要： In aspects, the present disclosure provides an apparatus for handling axial thrust in rotating equipment. The apparatus may include a thrust bearing and a runner having a contact surface engaging the thrust bearing. The runner may include passages extending between the contact surface and an opposing surface of the runner. The apparatus may further include a lock ring assembly that has channels in communication with the passages of the runner. In certain embodiments, one or more cavities may be formed on the contact surface of the runner. The cavities may be in communication with the internal passages of the runner. In aspects, the present disclosure provides a method for handling axial thrust in a pump assembly. The pump assembly may include a thrust bearing assembly that may include a runner having a contact surface engaging a thrust bearing pad. The method may include flowing a lubricating fluid to the contact surface using at least one internal passage formed in runner.

摘要： A submersible pump assembly has modules, including a rotary pump, an electrical motor, and a seal section located between the motor and the pump. The seal section has a tubular housing with a lower adapter secured to the housing and joining the seal section with the motor. An upper adapter is secured to the housing and joins the seal section with another one of the modules. An inlet port in the upper adapter admits well fluid into the housing. A tubular, flexible compensator element has an upper end sealed to the upper adapter and a lower end sealed to the lower adapter. A communication passage in the lower adapter admits lubricant from the motor into the compensator element. A cap is mounted around the upper end of the compensator element. The cap has a skirt extending radially outward to limit upward expansion of the compensator element.
摘要翻译：潜水泵组件具有模块，包括旋转泵，电动马达和位于马达和泵之间的密封部分。密封部分具有管状壳体，其下部适配器固定到壳体并将密封部分与马达接合。上部适配器固定到外壳上，并将密封部分与另一个模块连接。上部适配器中的入口允许将良好的流体进入壳体。管状的柔性补偿元件具有密封到上适配器的上端，并且与顶部适配器密封的下端。下部适配器中的连通通道允许从电机到润滑剂元件的润滑剂。在补偿器元件的上端安装盖。盖具有径向向外延伸的裙部，以限制补偿元件的向上膨胀。
