**Description:**
The rod pump is assembled on the surface and then connected to the sucker rod before being lowered into the well through the tubing. This design allows for efficient oil retrieval from deep underground reservoirs.
**Working Principle:**
During the upstroke, the plunger is at the bottom of the rod pump. The hydraulic pressure from the tubing causes both the traveling and stationary valves to close. As the plunger moves upward, the stationary valve opens, allowing oil to flow into the tubing due to the pressure differential between the bottom and the top of the pump.
During the downstroke, the traveling valve opens, and the pressure drives the oil into the plunger through the side hole of the extractor, which then flows into the tubing.
**Structure:**
The subsurface sucker rod pump consists of several key components including:
- Tubing Coupling
- Extension Nipple
- Barrel Coupling
- Barrel
- Traveling Valve
- Plunger
- Extractor
- Stationary Valve
