旋转运动

Studied pumping well system in this article, the intermediate power transmission parts uesed flexible rod, the downhole assembled rod pump, the ground driving device would transform up and down reciprocating motion into rotating motion. With own mechanism rounded trip for the downhole flexible rod and pump. Wellhead polished rod changed common stell for flexible polished rod. It was a innovation in theory study and craftwork method. It was a remarkable feature in this article, because these innovations were not studied and attempted for prehuman.
