作为一个井泵设计师,在设计工作完成后,期望泵的设计工况点是最佳工况点(即效率最高点),但如何预测,目前仍是一个难题.试制结束后,在性能试验时发现最佳工况点偏离设计工况点较远,如何修改设计方案,使最佳工况点与设计工况点基本吻合,也是极需解决的问题.用最经济的方法,只仅仅改变叶轮或导流壳的某一流道几何参数,就研制出不同性能的井泵,以扩大使用范围,来满足用户不同的需要,是工厂经营者、设计者及用户最感兴趣的事情.为
As a well pump designer, after the design work is completed, it is expected that the pump design condition point is the best condition point (ie, the highest efficiency point), but how to predict is still a problem.After the trial is finished, Found that the best working conditions deviate from the design conditions far, how to modify the design, so that the best working conditions and design points basically consistent, but also very much the problem to be solved.In the most economical way, only to change Impeller or diversion shell geometry parameters of a runway, the development of different performance of the well pump to expand the scope of use to meet the different needs of users, plant managers, designers and users are most interested in things.
