15-106 Size to 30-250 Size Oil Sucker Rod Pump

15-106 size to 30-250 size Sucker Rod Pump Description

A downhole Sucker Rod Pump is used on onshore sites to create a mechanical lifting motion. This motion is created by a series of valves, plungers, rod strings and rods that are assembled together as a pumping system. A Sucker Rod Pump works in the following way:

• A motor and gear box runs the power shaft.
• Counter weights are added to the cranks at the end and the cranks lift the counter weights.
• The Pitman arms connect the walking beam with the cranks. The beam then hinges and lowers the plunger. When the plunger and the horse head are lowered, it completes 1 downstroke.
• When the horsehead and plunger are lifted up, the fluid gets lifted from the bottom to the surface. This completes the upstroke.
• The fluid flow determines the opening and closing of the valves. The standing valve is opened while the riding valve is closed during the upstroke. During the downstroke, the standing valve gets closed and the riding valve is opened.

There are two aspects to consider when sizing the downhole pump for an installation. The first is that the pump capacity should be related to the well capacity. The pump displacement is determined on the basis of the pumping speed, unit stroke length, and plunger diameter.
