HIGH VOLUME AXIAL FLOW ELECTRIC SUBMERSIBLE PUMP (ESP) PUMP STAGE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18072240 titled 'HIGH VOLUME AXIAL FLOW ELECTRIC SUBMERSIBLE PUMP (ESP) PUMP STAGE
Simplified Explanation
The abstract describes an electrical submersible pump (ESP) assembly with an axial flow centrifugal pump stage, including an impeller and a diffuser with specific shapes and configurations.
- The ESP assembly includes an electric motor, a seal section, and an axial flow centrifugal pump stage.
- The centrifugal pump stage consists of an impeller attached to a drive shaft and a diffuser with specific vane configurations.
- The impeller has impeller vanes attached between an impeller hub and an impeller shroud, which is a straight-walled cylindrical shape.
- The diffuser has diffuser vanes attached between a diffuser hub and a diffuser shroud, also a straight-walled cylindrical shape.
Potential Applications
The technology can be used in various industries such as oil and gas, mining, and water management for efficient fluid pumping operations.
Problems Solved
The innovation addresses the need for reliable and high-performance submersible pumps for deep well applications, providing increased efficiency and durability.
Benefits
The benefits of this technology include improved pump performance, increased longevity, and reduced maintenance costs for pumping systems in challenging environments.
Potential Commercial Applications
The technology can be applied in commercial settings such as oil wells, mining operations, agricultural irrigation systems, and municipal water supply facilities.
Possible Prior Art
One possible prior art could be traditional submersible pump designs with different impeller and diffuser configurations. Another could be older ESP assemblies with less efficient pump stages.
Unanswered Questions
How does the impeller shape affect pump performance?
The specific shape of the impeller shroud is highlighted in the abstract, but the direct impact on pump performance is not discussed. Further research or testing may be needed to determine the significance of this design aspect.
Are there any limitations to the straight-walled cylindrical shapes of the impeller and diffuser shrouds?
While the abstract emphasizes the straight-walled cylindrical shapes of the impeller and diffuser shrouds, it does not mention any potential limitations or drawbacks of this design choice. Investigating any constraints or challenges associated with these shapes could provide a more comprehensive understanding of the technology.
Original Abstract Submitted
An electrical submersible pump (ESP) assembly. The ESP assembly comprises an electric motor having a first drive shaft; a seal section having a second drive shaft that is coupled to the first drive shaft; a third drive shaft that is coupled to the second drive shaft; and an axial flow centrifugal pump stage, wherein the centrifugal pump stage comprises an impeller coupled to the third drive shaft and a diffuser, wherein the impeller defines a plurality of impeller vanes attached between an impeller hub and an impeller shroud, wherein the impeller shroud is a straight-walled cylindrical shape, wherein the diffuser defines a plurality of diffuser vanes attached between a diffuser hub and a diffuser shroud, and wherein the diffuser shroud is a straight-walled cylindrical shape.
