摘　　要：介绍了下偏杠铃型抽油机的结构特点和工作原理。在几何学、运动学、动力学模型和评判曲柄轴扭矩的最佳判据模型的基础上开发了仿真软件,通过与普通型游梁抽油机仿真结果的比较,肯定了下偏杠铃型抽油机在工作性能上确实优于普通游梁抽油机,为进一步合理配置抽油机,实现结构优化、节约能源提供了科学方法和理论基础。Compared with conventional pumping units, a biased downward barbell type pumping unit and its structural characteristic and operating principle are introduced. The geometrical, ki- nematics, kinetic model and judging crank shaft torque＇s the most efficiency equation model are also established. On this model foundation, the simulated software is exploited. Compared with the emulation result of conventional pumping units, the biased downward barbell type pumping units are advanced at work capability. The theoretical foundation and scientific method are provided for farther optimizing the pumping unit structure, configuring the pumping unit reasonably, saving energy.
