Well Down Hole Insert Rod Series Sucker Rod Pump

Well Down Hole Insert Rod Series Sucker Rod Pump Description

There are seven major components for downhole rod pumps: standing and traveling valves, plunger, barrel, seating assembly, pull tube or valve rod (for insert pump), and the fittings that hold the assembled pump together.

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.
