Tapered Moineau Design Promotes Durability and Facilitates Downhole Drilling
This progressive cavity pump/motor, based on a tapered, Moineau-style design, is highly durable and facilitates deep oil well drilling. Progressive cavity pumps and motors belong to the positive displacement pump family since they rotate into the physical space occupied by a fluid, forcing it up the shaft. These pumps typically transport fluids to the earth’s surface or drive monitoring equipment deep into drill holes (also known as wellbores or exploration and extraction holes) to procure oil. The system’s progressive cavity mechanism includes a rotor (a rotating gear member) and a stator (a stationary gear member). It can operate as a pump for extracting fluids or as a motor through which fluids can flow to rotate the movable gear member. Existing rotary pumps tend to erode and break down when operated at high speeds. Researchers at the University of Florida have improved upon the standard electric progressive cavity pump system by developing a rotor that is smaller on one end. A tapered design allows the positive displacement pump to last longer. This Moineau-style pump/motor is well positioned to capture a significant portion of the global pump market, which is expected to reach $75.4 billion by 2016.
