【摘要】 本文从分析游梁式抽油机拖动中存在的问题出发,阐述了超高转差率电动机的特性及其拖动游梁式抽油机时获得节电、增液和改善机、杆、泵运行状况的机理。国内油田的使用情况表明,超高转差率电动机是拖动游梁式抽油机的比较理想的设备。更多还原

【Abstract】 On the basis of analysing the problems on driving pumping units, the paper describes the characteristics of extra high-slip motors and the mechanism for the benefits of reduction in power consumption, increase in production and improvement in the running condition of the pumping system when it drives beam-balanced pumping units. Application results in home oilfields in recentyears show that the extra high-slip motors are suitable for beam-balanced pumping units.更多还原
