为探索杆式泵在斜井中使用时接箍与油管间的磨损规律。作者利用了一台能精确控制侧向载荷的试验装置,在实验室内对不同侧向力和行程条件下的变化情况进行了观察和分析
In order to explore the wear law between the coupling and the tubing when the rod pump is used in the inclined shaft. The authors used a test rig that accurately controls lateral loads and observed and analyzed changes in different lateral forces and travel conditions in the laboratory
