An oil-well pump dynagraph. American Petroleum Institute (API), 1936. Xing Mingming received a B.S. degree in mechanical manufacture and automation from Liaocheng University, Liaocheng, China in 2009, and his MS degrees in mechanical design and theory from Yanshan University, Qinhuangdao, China,...
Their design makes them inherently inefficient although until now we had assumed them to be very high efficiency devices. The main reason for this problem is the seal design. This paper studies the internal forces and losses within a piston well pump....
pump exits the well through a connection on the body of the pump head. This is because the two systems are connected and all water flow must pass through the electric system first, then the Bison Pumps cylinder and pipe up to the pump head as shown in the diagrams above. This means ...

Electric submersible pump performance may be analyzed with the aid of a pressure-production diagram. This allows a quantitative interpretation of the influence of changing well parameters on the production rate and pump intake pressure (annulus fluid level). The effect of remedial measures such as re...
Almost all of the common well pumps are centrifugal in design, using spiral impellers to push or pull water up and out of the well. The most common of these is the above-ground centrifugal, where the motor and pump sit at or near the well. These pumps are capable of moving large ...
These may include an electronic submersible pump (ESP) cable, heating cable, chemical injection line, or a combination of the above. Hence, it is critical that the design phase of the cable protector be scrutinized in detail to ensure the cables that are installed are all adequately protected ...
There is something about being half-naked laying face down on a table while the doctor looks at the fluoroscope and manipulates a 6″ needle deep into your body. Call me crazy but is not within the fun region on any of my Venn diagrams. Regular readers will note that I have had 3 ...
Activating– This is “priming the cognitive pump” in order to recall relevant prior knowledge and experiences from long-term memory in order to extract and construct meaning from text. Monitoring Comprehension– Students who are good at monitoring their comprehension know when they understand what ...
He was also one of the first to apply mathematics to physical phenomena, founding hydrostatics and statics, including an explanation of the principle of the lever. He is credited with designing innovative machines, such as his screw pump, compound pulleys, and defensive war machines to protect ...
