潜油电泵导叶轮流道检测仪的研制

The design and manufacture of the flow-path inspecting instrument for idler pulleys and impellers of submersible pumps

潜油电泵以它特有的深抽、大排液量、经济有效的采油特点成为油田中后期增加产量的重要手段之一。作为潜油电泵重要组成部分的导叶轮,其流道的畅通情况直接决定了潜油电泵的排量。目前,在油田的实际应用中,还没有快速准确地检测导叶轮流道的方法。文章叙述了潜油电泵导叶轮流道检测仪的设计原理、结构及功能,并对检测结果进行了分析。

The use of electric submersible pumps with high flow-rate and high-head is one of the most efficient means in oil extraction at middle metaphase. The circulating situation of idler pulleys and impellers, as an important part of a electric submersible pump, determines the flow-rate of the pump to a great extent. At present, there is no quick and accurate method for flow-path inspecting. The flow-path inspecting instrument reported in this paper is just designed for this purpose.
