  • Patent number: 10844875
    Abstract: A self-cooling electric submersible pump having an integrated cooling system is provided. The cooling system is configured to cool and lubricate the electric motor section of the pump by expanding a compressed multi-component coolant fluid through flow channels within the motor. The coolant fluid contains a first fluid having a boiling point of at least 230° C. and a second fluid having a boiling point of less than 150° C. During pump operation the first fluid acts as a largely incompressible liquid and the second fluid behaves as a compressible gas. A compressor compresses the second fluid in the presence of the first fluid to produce a hot compressed coolant fluid from which heat is transferred to a production fluid being processed by the pump. The compressed coolant fluid is expanded through an orifice and into the motor flow channels, returning thereafter to the compressor.

  • Patent number: 10788040
    Abstract: The present invention relates to a method of operating an electric motor-driven centrifugal pump (3) in a hydraulic system (4) having at least one self-controlled load, where a gradient (dQakt/dt) of the volumetric flow rate (Qakt) of the centrifugal pump (3) is determined and the current set-point delivery head (Hsoll) of the centrifugal pump (3) is calculated from a mathematical operation on the gradient (dQakt/dt) weighted with a gain factor (K) and the last specified set-point delivery head (Hsoll,alt). The operation describes a positive feedback between the set-point delivery head (Hsoll) and the volumetric flow rate (Qakt). The gain factor (K) is determined from a calculation instruction that is modified dynamically during operation of the centrifugal pump (3) taking into consideration the current operating point of the centrifugal pump (3) and taking into consideration a current and/or at least one past state of the hydraulic system (4).
