石油矿场用往复泵λ值的讨论

Discussion on the ratio λ of reciprocating pump for oil field

随着钻井工艺和采油工艺的发展需要 ,石油矿场用往复泵在结构、材料、制造工艺等方面都发生了变化 ,由于往复泵的工作条件日趋恶劣 ,要求在进行泵的结构设计时 ,要有高的可靠性 ,良好的经济性及合理的结构设计参数 ,以满足钻井、采油工艺生产需求 ,现文讨论了曲轴偏心距 R和连杆大、小头孔中心距 L 的比值 λ(=R/L)对往复泵性能的影响。

With the development of drilling and oil producing technology,the structure,material and machining technology of reciprocating pump for oil field are most changeful.Because the operating condition of reciprocating pump is getting worse,it is required that the reciprocating pump must have high reliability,excellent performance of economy and reasonable parameters of structure design and oil producing technology.In this paper,the effect of λ upon performance of reciprocating pump is discussed. λ is the ratio of R ,the crankaxle eccentricity,to L the distance from the center of large end to the center of small end of connecting rod.
