摘　　要：针对常规抽油机的缺陷,研制了一种新型顶驱同步抽油机,该抽油机采用永磁同步电机为动力,直接驱动主动轴,带动扁平皮带或同步带以提升井口载荷作上下往复运动;无减速和机械换向装置,采用变频电源和先进的控制理论和技术、精确的位移监测系统,冲程、冲次全部实现无级可调,运行曲线平滑,机杆泵的受力状况得到明显改善;对油井的产能和油品性质适用范围广,系统效率高。由于整机采用塔架结构,所以冲程长度的增加只需增加机架高度,而不需要改变其它部件,整机重量轻,结构简单,是现有抽油机的理想替代产品,具有很好的推广应用前景。Aim at the limitation of general well pumping unit,a new top drive in-phase well pumping unit is developed,it's power is always magnetism in-phase electricity,can drive initiative axis,and bring along flat belt or in-phase belt to enhance wellhead load for pump,and no decelerate and machine converted direction.Using frequency conversion power supply,advanced theory and technique,accurate displacement monitoring system,and has fulfilled stepless adjust stroke and pumping speed,running curve smoothness,and force status of well pumping unit-sucker rod-oil well pump has greatly improved.well pumping unit frame heightened can lengthen a stroke due to it has tower frame,so whole unit weight light,structure simple,and is a ideal substitute for in existence well pumping unit,has a better application foreground.
