【摘要】 在使用有杆泵抽油的油井上,对抽油载荷进行均衡具有很重要的意义。文中介绍了几种均衡的方法、原理及特点,重点讨论了使用大转差率电动机对抽油载荷的均衡作用,对均衡中的一些问题作了系统的定性、定量分析,认为该均衡方法可以延长抽油机减速箱的使用寿命,可以节约能源。更多还原

【Abstract】 It is of great importance to sucker rod pumping units to achieve uniform load in operation. This paper presents anumber of methods, including principles and characteristics, for this purpose. And the author focuses the discussion on the application of high-slip motors and interprets in light of qualitative and quantitative analysis that the application of high-slip motora will result in extended service life of gear reducers and more efficient energy consumption.更多还原
