摘要: 介绍了新型载荷自适应五连杆抽油机的结构组成，推导出了载荷自适应五连杆抽油机的运动计算和动力计算的理论公式。以CYJZ10-4.2-53HB型载荷自适应抽油机为计算实例，论述了该五连杆抽油机的性能特点，并与偏置抽油机进行了对比。计算结果表明，在相同的条件下，载荷自适应五连杆抽油机可节电8.65%以上，连杆拉力减少44.94%，减速器峰值扭矩减少16.83%，是一种比较有发展前途的节能抽油机。

Abstract: The structure of the new load adaptive five-link-rod pumping units was introduced, and the theoretical formulae for the motion calculation and dynamic calculation of the adaptive five-link-rod pumping units were deduced. By taking the CYJZ10-4.2-53HB adaptive pumping units as an example, the performance characteristics of the five-link-rod pumping units were discussed and compared with the offset pumping units. The results show that under the same conditions, the adaptive five-link-rod pumping units can save energy more than 8.65%, decrease 44.94% of connecting rod tension with 16.83% decrease in the peak torque of the gear reducer, and it is a promising energy-saving pumping unit.
