The working mechanism of tubing pumps involves mounting the pump barrel assembly directly onto a tubing string, while connecting the plunger assembly to a sucker rod string. The up and down reciprocal movement of the plunger assembly facilitates the production process. One key advantage of this setup is that in the event of any operating issues with the traveling and fixed valves, the valve side problem can be resolved using the sucker rod, piston, and extractor, without the need to remove the entire pump and tubing string from the well. This not only minimizes work intensity but also reduces operation costs.
