Definitions

  • centrifugal pumps in well-sampling and monitoring applications generally employ a single impeller that is closely coupled to an electric motor that is positioned with a sealed enclosure. Accordingly, numerous difficulties are encountered in the design and operation of well-sampling and monitoring applications that are not present in larger multi-stage devices. For example, relatively long electrical lead lengths may introduce undesired transient electrical loading conditions that may adversely affect the motor, the power supply, or both.
  • FIG. 6 is a diagrammatic block view of a subsurface unit according to the various embodiments.
  • the power converter 50 includes a DC-to-DC converter 52 that is configured to be coupled to a DC power supply at input terminals 54 , and to provide a selected DC output at output terminals 56 .
  • the DC-to-DC converter 52 may include a “buck-boost” device that is structured to accept an approximately constant input voltage V DC, IN and to provide a variable output voltage V DC, OUT that may range above or below the input voltage V DC, IN .
  • a motor speed distribution 120 is shown, which may be implemented by the motor speed controller 116 .
  • a motor speed distribution 122 is approximately linear, so that the speed of the motor 94 increases from stationary to a full speed value at a constant rate. Accordingly, upon being energized, the motor 94 reaches a maximum speed at a time T, which in an embodiment, may be approximately one to three seconds.
  • a motor speed distribution 124 is approximately parabolic (e.g., a polynomial of second degree), so that the speed of the motor 94 increases at a variable rate upon being energized.
  • a motor speed distribution 126 may have still other shapes, such as a third-degree polynomial, so that the speed of the motor 94 increases at still another non-constant rate.
