Prime movers (prime mover) is in the header of the transmission then passed to a pair of crank, usually with counterweights. Then converted into motion up and down the arm pit. then forwarded to the walking beam, at the end of the walking beam horse head there (because of its shape similar to a horse’s head).
At the bottom of the horse’s head, there is a cable (bridle), is typically made of steel or fiberglass. Bridle is connected to the polished rod, then polished fastened to the piston rod that passes through tubing (a pipe that extends to the bottom of the well through the fluid is sucked). Piston is the one that serves to suck fluid from the basement toward the top of the mechanism – the mechanism mentioned above.
Bottom of tubing are down-hole pump. The pump consists of two valves, valve stationary below also called “standing valve”, and a valve on the piston is connected to the bottom of moving up and down, known as the traveling valve.
At the bottom of the well fluid entering through the perforations that have been made through the casing (casing is larger pipes that are embedded in the well). When the piston moves up the traveling valve will be closed and the standing valve open. Due to the decrease in pressure within the barrel, so that the fluid entrance and the fluid piston lift up. When the piston starts moving downwards, traveling valve open and standing valve is closed due to an increase in pressure in the pump barrel. Then the piston reaches the end of the above steps and back again, this process continue running.
