【摘要】 采用径向导叶的液氢泵的试验结果表明,导叶损失大,导致液氢泵效率低。提出了一种液氢泵流道式导叶的设计方法,并针对某液氢泵设计了级间导叶,试验结果表明,设计方法合理,降低了级间导叶的损失,提高了液氢泵的效率。更多还原

【Abstract】 The results,which obtained by using radial diffuser,show that due to the high loss through the diffuser,the efficiency of the liquid hydrogen pump is lower.The author proposed a design method for continuous channel diffuser of liquid hydrogen pump,and designed a interstage crossover for a liquid hydrogen pump.The testing results indicate that,the loss through the interstage crossover is reduced and the efficiency of the pump is improved.更多还原
