| 摘 要： | 针对常规游梁式抽油机的驱动系统效率提升空间有限,能耗整体偏高等问题,提出了盘式电机驱动自平衡游梁式抽油机的结构方案。采用盘式永磁电机直接驱动减速器,不需要皮带传动,从而提高地面系统效率; 利用永磁电机的变频调速特性,并结合游梁尾部设计的自动调平衡装置,形成了一套自平衡式抽油机控制方案。根据直驱抽油机对电机尺寸和效率的要求,对盘式电机结构进行优化设计,电机效率可达93.8%。提出 “粗精结合”的自平衡调节方案,以曲柄平衡调节为主、游梁自动平衡调节为辅,建立了根据功率平衡度自动调节平衡的控制策略,实现了抽油机无极调速。电机测试和抽油机现场试验表明:运行过程中盘式永磁电机性能稳定,带动抽油机整体运行平稳可靠,日耗电量下降19.5%,具有良好的节能效果。

| Abstract: | The driving system of the conventional beam pumping unit has low operating efficiency and high energy consumption. Therefore, a new beam-pumping unit structure with a semi-direct drive and self-balancing system was proposed. The newly proposed beam pumping unit is directly driven by a disk permanent magnet motor, eliminating the belt and improving the efficiency of the ground system. A control scheme of a semi-direct drive self-balancing pumping unit was developed based on the permanent magnet motor's frequency conversion and speed regulation character-istics combined with the automatic ba lancing device designed at the tail of the beam.
