摘　　要：针对级间抽气的需要,介绍了通过改变抽气蜗壳截面形状及相交面倒角,进一步优化级间抽气结构。分析结果表明,所设计的结构能够在满足抽气流量要求的条件下保证机组的高效率运行。According to the requirement of air exhausting between stages, the air exhausting structure between stages is further optimized by changing the sectional shape of air exhausting volute and chamfer of intersection plane. The analyzing result shows that the designed structure can make the unit running high-eflqciently under the condition of meeting air exhausting flow requirements.
