5. **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. It is specifically designed for downhole oil extraction operations.
6. **Working Principle:**
During the upstroke, the plunger is at the bottom of the pump. Due to hydraulic pressure from the tubing, both the traveling and stationary valves close. As the plunger moves upward, the stationary valve opens, allowing fluid to flow into the tubing due to higher pressure at the bottom.
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.
7. **Structure:**
The subsurface sucker rod pump consists of several key components including the tubing coupling, extension nipple, barrel coupling, barrel, traveling valve, plunger, extractor, and stationary valve. Each part is engineered for optimal performance and longevity.
