Abstract
A fluid controlled pumping system includes a pumping unit disposed within a fluid cavity. The pumping unit includes a passage extending to a suction end of the pumping unit. The system also includes a pressure source coupled to the passage and operable to force a fluid outwardly from the passage proximate to the suction end of the pumping unit. The system includes a pressure sensor coupled to the passage and operable to determine a fluid pressure within the passage. The system further includes a controller coupled to the pumping unit and operable to regulate an operating parameter of the pumping unit using the fluid pressure.
Claims35
A fluid controlled pumping system, comprising:
- a pumping unit disposed within a fluid cavity, the pumping unit having a passage extending to a suction end of the pumping unit;
- a pressure sensor coupled to the passage and operable to determine a fluid pressure within the passage;
- and
- a controller coupled to the pumping unit and operable to regulate a fluid lubrication of the pumping unit in response to the fluid pressure, the regulation comprising decreasing a flow rate of the pumping unit in response to a decrease in the fluid pressure, and increasing a flow rate of the pumping unit in response to an increase in the fluid pressure.
A method for fluid controlled pumping, comprising:
- providing a pumping unit disposed within a fluid cavity, the pumping unit having a passage extending to a suction end of the pumping unit;
- forcing a fluid outwardly from the passage proximate to the suction end of the pumping unit;
- determining a fluid pressure within the passage;
- and
- automatically regulating a fluid lubrication of the pumping unit in response to the fluid pressure, the regulation comprising decreasing a flow rate of the pumping unit in response to a decrease in the fluid pressure, and increasing a flow rate of the pumping unit in response to an increase in the fluid pressure.
A method for fluid level controlled pumping, comprising:
- providing a pumping unit within a cavity, the pumping unit having a suction end operable to draw a cavity fluid into the pumping unit for transfer of the cavity fluid from a first location to a second location;
- determining a pressure proximate to the suction end of the pumping unit, the pressure corresponding to a depth of the cavity fluid within the cavity;
- and
- automatically regulating a fluid lubrication of the pumping unit by regulating a flow rate of the cavity fluid via the pumping unit using the determined pressure, wherein regulating the flow rate further comprises:
- receiving a first signal from a pressure sensor indicating the pressure;
- and
- transmitting a second signal to a drive motor, the drive motor coupled to the pumping unit and operable to control the flow rate of the pumping unit.
A fluid level controlled pumping system, comprising:
