摘要
为了开发出一种高效率低比转数 (ns<70 )的蜗壳泵 ,总结了比转数ns=60时的两种试验结果 ,进行了叶轮设计和蜗壳设计的优化 ,并进行了新的试验 ,以揭示叶轮与蜗舌之间的流动干扰。结果表明 ,低比转数蜗壳泵不宜采用常规设计 ,进而提出了一种新的设计方法。
To develop a high efficiency volute pump in the very low n s range, two kinds of test results at n s =60 are summarized, the optimization of impeller using 11 impellers and the optimization of volute casing changing volute design parameters are done, and new test is added to reveal the flow interference between inpeller and volute tongue. The results reveals that the conventional design is not suitable for designing a very low n s volute pump and a new design is presented.
