An intake section for an electric submersible pump (ESP) assembly comprising an outer housing with a plurality of inflow ports distributed across an outer surface of the intake housing in a proportional pattern. The size and shape of the plurality of inflow ports within the proportional pattern are configured to distribute the inflow flowrate of fluids across the outer surface of the intake housing.

Radial inflow hole geometry

An electrical submersible pump assembly comprising a first section and a second section with an outer housing and a drive shaft. A coupling assembly comprising a coupling, a first and a second locking keys, and a plunger assembly mechanically couples the first drive shaft to the second drive shaft. The coupling is cylindrical in shape with splines configured to transfer torque from the first drive shaft to the second drive shaft. The plunger assembly extends the first and second set of locking keys from a key port in the first shaft and second shaft into a groove within the coupling. The coupling assembly is configured to transfer tensile stress from the first drive shaft to the second drive shaft in response to extending the first locking key in the first groove and the second locking key in the second groove of the coupling.

Spring actuated axially locking shaft coupling for bi-directional loading

An electrical submersible pump assembly comprising a first section and a second section with an outer housing and a drive shaft. A coupling assembly comprising a coupling, a thrust pin, and a retainer ring mechanically couples the first drive shaft to the second drive shaft. The coupling is generally cylindrical in shape with splines formed along the inner surface configured to transfer torque from the first shaft to the second shaft. The thrust pin is installed in a pin bore in the lower shaft and extends into a retainer bore in the upper shaft. The retainer ring is installed between a groove in the retainer bore and a retainer groove on the outside of the thrust pin. The thrust pin is configured to transfer tensile stress from the retainer bore in first drive shaft to the pin bore in the second drive shaft.
