How do pump jacks work

How does an oil pump jack work? What is a pump jack used for? A pumpjack is the overground drive for a reciprocating piston pump in an oil well.

It is used to mechanically lift liquid out of the well if not enough bottom hole pressure exists for the liquid to flow all the way to the surface. The arrangement is commonly used for onshore wells producing little oil. Pumpjacks are common in oil-rich areas.

Often this is an emulsion of crude oil and water. A hydraulic jack uses a flui which is incompressible, that is forced into a cylinder by a pump plunger. Oil is used since it is self lubricating and stable.

When the plunger pulls back, it draws oil out of the reservoir through a suction. I have to begin by disagreeing with other post as jumping jacks are not just a way of warming up. Jumping jacks are considered a form of aerobic exercise.

It is a good thing that you can do 2with ease. I would continue to do jumping. The pump is made up of several components. In some cases, the. An electric or gas-driven engine rotates a counterweight, attached to an arm that moves a pivoting beam up and down.

A cable at the opposite end pulls a rod assembly up, and drops it down again. This process of creating artificial lift simply increases the pressure within an oil well to pull oil to the surface. It is common for there to be insufficient pressure in the reservoir to push oil to the surface, and thus this artificial lift is used to increase production from a well.

Modern pumpjacks draw power from specialized engines, known as prime movers, which run off electricity or gas. A cable sits at the other en and it produces an up-and-down motion on a rod assembly. As the head of the pumpjack bobs the up and down, the rod extending down into the well moves up and down, driving a pair (or more) of one-way check valves.

They seal and pull oil up on the upstroke, but leave it behind on the downstroke, producing a gradual progression of oil toward the surface. The check valves show up as little dots in the schematic diagram below. Wish there was a faster way to add midrails for OSHA?

Without speed modules, one pumpjack cycle takes one second to complete. The brackets are designed to be raised and lowered in a manner similar to an automobile jack. NOTE: The requirements on this page are specific to pump jack scaffolds only. A pump jack is a device used in oil production when the pressure inside a well is not sufficient to force oil to the surface.

HOW A RECIPROCATING PUMP WORKS WATER PUMP ALTERNATIVE OPERATION AND MECHANISM ANIMATION. Richard Hubbard 4289. Jacks must have a source of external power that allows the jack to exert force. Every week students, engineers and curious people from all walks of life ask us what makes a jack work and are quite surprised to hear that the answer is simple leverage. Pump Jack - Duration: 1:18.

Putting that foot handle into the little pump piston handle yoke and pushing down with the force in your arm does the trick. As a general rule, the larger the pumpjack, the deeper the reservoir. The typical pump comprises an A-shaped frame topped by a long bar or beam.

One end of the beam is connected to a motor. The turning motor operates a linkage that causes the beam to work back and forth like a seesaw.
