1) head maximum approach
极大扬程设计法
1.
To overcome the difficulty that deep well pump diameter is restricted by the well diameter and the disadvantage of the old design which can t utilize the space to develop the head,by head maximum approach,a new type 100SJB8 was developed which raised the head by 50% and raised the efficiency by 9.
深井离心泵在机井内工作,其外径受井径的限制,为了解决原有的设计方法难以充分地利用有限的空间来进一步提高单级扬程的问题,采用自主创新的极大扬程设计法,成功研制出了100SJB8新型深井离心泵,测试结果表明该泵的单级扬程提高了50%,而且效率超过国家标准9。

The impeller diameter maximum approach has been developed to solve the problem that deep well pump diameter was restricted by the well diameter.
针对深井离心泵外径受井径限制的结构条件,研究了一种深井离心泵叶轮极大直径设计法,其特点是将叶轮前盖板直径扩大到泵体内壁边缘,使叶轮直径在相应的井径条件下达到极大值,它与反导叶导流壳配套,可以使泵体轴向长度减短到极小值。
