摘要(Abstract)：

对压紧式潜油泵叶轮和导叶的受力状态进行了理论分析,建立了受力与变形关系式,得出叶轮轮毂的受压变形量与导叶的受压变形量不能保持一致。结合使用和装配条件,利用叶轮在导叶中的轴向可窜动间隙,建立了压紧式潜油泵叶轮轮毂长度的设计方法,提出了工艺保证要求。通过设计验证,泵的综合性能符合API标准要求。在苏丹油田含砂井应用,泵的平均运行寿命由普通潜油泵200天左右提高到一年以上,起到了很好的防砂效果。
The force of the load on the impeller and diffuser in the electrical submersible compression pump is analyzed in theory,related pressure and deformation for impeller and diffuser.The conclusion is that the deformed amount of impellers is different from that of diffusers in working place,and be verified that the location of impellers is different each other in diffusers along axis.Based on the working state analysis,and combined with implementation,the equations for calculating the length of the impeller hub are worked out,and emphasized that some important dimensions must be controlled in machining.It is testified that this method is effective and practicable by using in large quantities.
