An inside conical surface at the lower end of the joint is designed to ensure the shaft swing freely within an angle range of 10°, thereby the axial bending stress caused by the deflection of the borehole can be eliminated effectively.
这种装置采用类似球形关节的旋转机构，消除了抽油杆柱上下往复运动产生的倒扣扭矩；在短节下端设计有10°的内圆锥表面，使转轴能够在10°范围内自由转动，从而有效地消除了由于井身弯曲而产生的轴向弯曲应力。

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.
本文所研究的抽油系统，中间动力传动部件采用柔性抽油杆，井下配套杆式抽油泵，其地面驱动装置将传统抽油机驴头的上下往复运动变为旋转运动，并且能够利用自身结构对井下柔性抽油杆及泵体实现起下作业，井口光杆也由普通钢质光杆变为柔性光杆，这是理论研究和工艺方法的创新，这些创新都是前人所没有研究和尝试的，是本文的一大显著特点。

This thesis aimed to discuss an electromagnetic energy harvester. Motion of a fluid driven by a 30 Hz pulse pump is used to activate the electromagnetic energy harvester. The periodic motion of the fluid in the chamber causes a harmonic vertical deflection in the diaphragm on which a permanent magnet is attached. Subsequently, the vibration of this magnet induces an output voltage in a solenoid hanging above it.
中文摘要本文是探讨电磁式能量产生器的机构，此电磁式能量产生器的主要作动方式为藉由频率30Hz的脉冲马达驱动工作流体，使工作流体呈周期性的流动让帮浦腔体上致动薄膜产生周期性的上下往复运动，因此帮浦腔体内产生压力周期性的变化，在薄膜上永久磁铁的振动，使得螺旋线圈感应产生电压的输出。
