    摘要: An electric pump powered by an electric motor having a stator disposed within a hollow rotor is provided. Impellers on the rotor outer surface extend into a fluid flow path defined by the pump. One or more torque-producing rotor sections are driven by a plurality of independently controllable stator sections disposed within the rotor cavity. The relative positions of the rotor and stator are maintained by a plurality of bearings configured to allow rotation of the rotor and defining a bearing span. The pump is configured such that the stator and rotor share the same bearing span. Such an arrangement reduces motor windage losses relative to conventional motors in which the rotor is disposed within the stator, owing to a reduction in the diameter of the air gap between the stator and the rotor. In addition, the peripheral speed of the pump is increased owing to an increase in the rotor diameter.

    摘要: A system for enhancing a flow of a fluid induced by a rod pumping unit is provided. A pumping control unit is configured to control stroke movement of the rod pumping unit. The pumping control unit is configured to store a first set of stroke timing data based on a first pressure level and a second set of stroke timing data based on a second pressure level, store a set of pressure weights, and receive a current pressure level. The current pressure level is between the first pressure level and the second pressure level. The pumping control unit is also configured to determine a current set of stroke timing data based on the current pressure level, the first set of stroke timing, the second set of stroke timing, and the set of pressure weights, and initiate at least one stroke of the rod pumping unit.
