Product Description

Oil Sucker Rod Pump Overview

The 15-106 to 30-250 size oil sucker rod pump is a mechanical downhole pumping system designed for onshore oil extraction operations. This chrome-plated pump creates efficient lifting motion through a coordinated system of valves, plungers, and rod strings.

Operating Principle

The sucker rod pump operates through a precise mechanical cycle:

A motor and gear box drive the power shaft to initiate movement
Counter weights on the cranks provide balanced operation
Pitman arms connect the walking beam with cranks for smooth transmission
The beam hinges to lower the plunger, completing the downstroke
During upstroke, the horsehead and plunger lift fluid from bottom to surface
Valve operation is fluid-controlled: standing valve opens during upstroke while riding valve closes, and vice versa during downstroke

Sizing Considerations

Proper pump sizing requires matching pump capacity to well capacity. Pump displacement is calculated based on pumping speed, unit stroke length, and plunger diameter to ensure optimal performance and efficiency.
