摘　　要：在我国节能与环保的大背景下,电厂脱硫氧化和生物发酵等领域对所需的离心压气机提出了新的设计要求:大流量、高压比、高效率。因此,根据企业和市场的实际需求,开发了首台大流量(500Nm3/min)、高压比(级压比3.6)、单级高速离心压气机。利用自主开发的离心压气机气动设计程序提供几何数据,通过三维数值模拟手段评估离心压气机各项性能,最终由样机试验确定设计是否达标。试验结果显示各项性能参数均满足设计指标。由于不需要使用中间冷却器,相对于目前市场上应用的两级离心压气机产品而言,所研发的单级离心压气机具有结构简单、制造成本低、效率高等特点。To satisfy the requirements of modern industrial applications,centrifugal compressors with challenging design parameters are needed. A single-stage high-speed centrifugal compressor with a volume flow rate of 500 Nm-3/min and a total pressure ratio of 3.6 was designed in this study. One-dimensional in-house aerodynamic programs were used to provide geometry data. Numerical simulations were conducted to evaluate the performance of the centrifugal compressor. The experiment finally validated its performance and indicated that the results fulfilled the expectations. Due to the absence of an intercooler, compared to two-stage centrifugal compressor products,the single stage centrifugal compressor developed here features a simple structure, low manufacturing cost,and a high efficiency rate.
