本文探讨了常规抽油机的节能机理,并提出了适用于在用常规抽油机节能改造及新型节能抽油机制造的两种设计方案。最后介绍了“改造机”的现场实验情况及节能、增产效果,并对节能抽油机的适用范围提出了初步看法。
This article explores the energy-saving mechanism of conventional pumping units and presents two designs that are suitable for energy-saving retrofits using conventional pumping units and new energy-saving pumping units. At last, the field experiments of “Retrofit Machine” and the results of energy-saving and production increase are introduced, and a preliminary view is given to the applicable range of energy-saving pumping unit.
