半开式污水泵叶轮设计方法的探讨

Research the Designing Method of Semi-opened Sewage Pump Impeller

根据对不同叶片数半开式叶轮的试验研究,介绍了半开式叶轮的设计方法,给出了叶轮设计中的经验公式及经验参数,详细研究了叶片数、叶片边缘间隙对水泵性能的影响,并对设计中出现的一些问题进行了讨论。

According to the experimental study on varied blade numbers of semi-opened impeller, thispaper researches the designing method of semi-opened impeller, introduces the experience formula and theexperience parameters during the procedure of designing impeller. The effect of the blade numbers and theblade edge clearances on the pump performance are studied in detail and some problems met in the procedureare discussed.
