Abstract: A protector for an electric submersible pump includes a plurality of chambers, with adjacent or consecutive pairs of chambers coupled, e.g., fluidly coupled, via a series or parallel body. The body defines two separate hydraulic circuits, which allows for the inclusion of a shaft seal, even when the body couples consecutive chambers in a parallel configuration or couples to a thrust bearing chamber. The shaft tube circuit can include a compensator and/or a relief valve.

Abstract: A system and methodology are provided for enhancing the life and usefulness of a thrust bearing assembly in a submersible pumping system component. The technique utilizes a thrust runner positioned adjacent a thrust bearing in the submersible pumping system component. The thrust runner is rotated relative to the thrust bearing via a shaft. Gas that may accumulate in a lower region beneath the thrust runner is vented through a passageway from the lower region to an upper region above the thrust runner. The gas is vented to help maintain a hydrodynamic fluid film between the thrust runner and the thrust bearing.

Abstract: A technique facilitates the reduction of vibration in a variety of devices which have rotating components. According to an embodiment, a system may combine a shaft, a rotor mounted along the shaft for rotation with the shaft, and a vibration reduction system. The vibration reduction system incorporates the use of a key and keyway in a manner which helps balance the rotor, thus reducing vibration during operation. In some applications, the vibration reduction system is able to reduce eccentric positioning of the rotor on the shaft due to, for example, assembly clearances.
