Abstract: A variable frequency drive (VFD) cabinet ventilation system, apparatus and method is described. A VFD cabinet includes an internal air circulating closed circuit that extends through an inside of an air-to-air heat exchanger and an external air open circuit extending around an outside of the heat exchanger. The circulating internal air closed circuit extends through a chamber closed to ingress of external air, the chamber including electrical components of a VFD system. The external air open circuit makes a turn from downwards to upwards before flowing through a VFD chassis including a drive of the VFD system. A VFD cabinet ventilation method includes turning a flow of cabinet ventilation air from downwards to upwards to separate dirt from the ventilation air, passing the separated ventilation air through a VFD chassis, and circulating internal cabinet air through a closed circuit including an inside of a heat exchanger.

Abstract: A torque transfer system for centrifugal pumps. A torque transfer system for a centrifugal pump includes a bearing sleeve above an impeller, the bearing sleeve and a hub of the impeller surrounding a rotatable shaft and coupled to the rotatable shaft by a key, the bearing sleeve having a stepped bottom edge, a top edge of the hub stepped inversely to the bottom edge of the bearing sleeve such that the top edge and the bottom edge interlock with a clearance between longitudinally extending portions of the interlocked edges, wherein upon reduction of torque transference between the key and the sleeve, the clearance closes such that the longitudinally extending portion of the stepped top edge contacts the longitudinally extending portion of the stepped bottom edge thereby maintaining rotation of the sleeve with the rotatable shaft. A centrifugal pump includes modules with a series of stepped, interlocked impellers.

Abstract: An apparatus, system and method for treatment of an electric submersible pump (ESP) power cable is described. A method of treating an ESP power cable includes wrapping an ESP power cable around a reel as the cable is removed from a production well to form cable layers, supporting the cable-wrapped reel horizontally above a tank, the reel supported on a shaft extending between actuatable support members, pumping treatment fluid into the tank, lowering the cable-wrapped reel partially into the tank by activating the actuatable support members such that a lower portion of the reel is submerged in the treatment fluid and an inner diameter of the cable-wrapped reel is fluidly coupled to the treatment fluid, rotating the reel around its central axis such that each portion of an outermost layer of the cable is submerged in the treatment fluid at least once to coat the ESP power cable.
