摘要:

为了实现低速大转矩运行,传统游梁式抽油机一般由原动机(通常为感应电机)经过皮带和齿轮箱减速驱动。各驱动环节的额定效率较高,但是抽油机在运行过程中的负载变化幅度较大,平均负载率较低,造成驱动系统的平均效率较低。同时,皮带和齿轮箱润滑油属于消耗品,需要定期更换,还存在一定的安全和环境污染隐患。随着设备运行时间的延长,高速旋转的感应电机、磨损老化的皮带和齿轮箱均会发出较大的噪音。基于上述原因,研制了基于同心式磁性齿轮原理的永磁复合电机,该永磁复合电机具有高效高转矩密度的特点,取代抽油机原有的传动系统,直接驱动游梁式抽油机曲柄旋转。现场实际应用表明,该型抽油机在大庆油田、中原油田和辽河油田取得了较满意的效果。

Abstract:

To achieve low-speed high-torque operation, the conventional beam pumping unit is generally driven by prime motor (induction motor)decelerating through belt and gear box. Although the rated efficiency of each driven link is relatively high, the load of beam pumping unit varies greatly with low average load rate, leading to low average efficiency of the driving system. Meanwhile, the belt and lubricating oil of gear box are consumable and require regular replacement; there are also some safety risk and environmental pollution hazards. With the passing of operation time, the induction motor under high-speed rotation as well as the waring and aging belt and gear box will produce loud noises. For the above reasons, a permanent magnet integrated motor is developed based on the principle of concentric magnetic gear, characterized by high efficiency and high torque density; after replacing the original drive system of pumping unit, it can directly drive the crank rotation of beam pumping unit. Satisfactory achievements have been made in Daqing, Zhongyuan and Liaohe oilfields.

Key words: beam pumping unit, direct driving, low-speed high torque, magnetic gear, permanent magnet integrated motor (PMIM)
