异相平衡抽油机节能原理探讨

Exploration into the Power-Saving Mechanism of Phased Pumping Units

异相平衡抽油机是一种变几何形状抽油机,与常规抽油机相比,扭矩变化均匀,上冲程时间增长,抽油机-深井泵系统效率高,试验结果证实效率可提高3％。研究表明,抽油机-深井泵系统效率随抽油机平衡度的增加而提高,建议抽油机平衡度以大于85～90％为宜。

The phased pumping units are those on which the geome-tric design has been changed, As compared with the conven-tional units, they are featured with uniform torque changes,longer upstroke period and higher efficiency of the pumpingsystem. Studies show that the system efficiency rises alongwith the increase of the extent of counterbalance of thepumping units and can be raised as high as 3 percent. Theauthors suggest that the extent of counterbalance should begreater than 85-90 percent.
