【摘要】 采用数值分析方法对抽油机“换向功”的理论进行了量化分析,结果表明,随抽油机结构参数的不同,其“换向功”与其输出总功的比值也有明显的差别,充分说明了抽油机结构特点及其参数不同对其节能有着不可忽略的作用,进一步丰富了“换向功”的理论并证实了“换向功”理论的实际意义。更多还原

【Abstract】 By using of numerical value analysis,we did the quantity analysis of the concept of"reversion work"on pumping unit.The result shows obvious difference between"reversion work"and out put work as the structure parameter of pumping unit changes,that indicates that its energy-saving is not ignored thus to enrich the theory and practical importance of"reversion work".更多还原
