Latest Patents

One of his latest patents is for a metal-to-metal sealing for diffusers of an electrical submersible well pump. This invention includes a centrifugal pump assembly with a housing featuring a cylindrical internal side wall. The design incorporates upper and lower diffusers, with a metal-to-metal seal that effectively seals the upper end portion of the lower diffuser to the lower end portion of the upper diffuser. The seal's outer surface frictionally engages the internal side wall of the housing, and it is energized by an axial force exerted between the diffusers. Another version of this invention includes a metal seal ring located in mating recesses on the outer walls of the diffusers, while an alternative design features an inner lip on one diffuser end that deflects an outer lip on the other end.

Additionally, Johnson has developed self-aligning and vibration damping bearings in a submersible well pump. This assembly consists of a centrifugal pump with stages, each containing an impeller and a diffuser. A shaft from an electrical motor rotates the impellers, and a thrust runner is coupled to the shaft for synchronized rotation. The design includes a bushing that is non-rotatably mounted in a receptacle in the diffuser, allowing for limited radial movement relative to the diffuser.
