Sucker rod string design of the pumping systems

Ingeniería e Investigación, 2015
The existing design of sucker rod string mainly focuses on the simplifying assumptions that rod string was exposed to simple tension loading. And its goal was to have equal modified stress at the top of each taper. The improved rod design was to have the same degree of safety at each section, and it used a dynamic force distribution that was ...

A Dual Barrel Well Washable Screw Pump

Shiyou jixie, 2016
Well washing is unable to conduct after solid screw pump is set.The settled sand on the pump usually leads to high torque of sucker rod when re-open, causing overload of sucker rod and leading to rod breaking off and thread damage.The necessity of ...

Performance Analysis and Evaluation of HY Type Sucker Rod

Shiyou jixie, 2017
The sucker rod is a power transmission device connecting the pumping unit and the deep well pump, which is an important part of the rod pumping system. The failure of the sucker rod directly affects the normal production of the artificial lifting system.
