2. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...

3. Truckmount carpet cleaner - Wikipedia

   en.wikipedia.org/wiki/Truckmount_carpet_cleaner

   Traditionally, truckmount carpet cleaning machines have been more powerful than portable carpet cleaning units. Although recent changes in technology have allowed portable manufacturers to approach the power of truckmount carpet cleaning machines, to date truckmounts are more powerful as they produce the cleaning power from an engine and electric portables generate the cleaning power from an ...

   en.wikipedia.org/wiki/Extraction_of_petroleum

   Tertiary recovery begins when secondary oil recovery is not enough to continue adequate extraction, but only when the oil can still be extracted profitably. This depends on the cost of the extraction method and the current price of crude oil. When prices are high, previously unprofitable wells are brought back into use, and when they are low ...

7. Electroosmotic pump - Wikipedia

   en.wikipedia.org/wiki/Electroosmotic_pump

   Electroosmotic pumps are fabricated from silica nanospheres [6] [7] or hydrophilic porous glass, the pumping mechanism is generated by an external electric field applied on an electric double layer (EDL), generates high pressures (e.g., more than 340 atm (34 MPa) at 12 kV applied potentials) and high flow rates (e.g., 40 ml/min at 100 V in a pumping structure less than 1 cm 3 in volume).
