本文详细介绍了美国 NREC 公司为美国 APCI 公司提供的氮气透平膨胀机工作轮和扩压器的设计方法。由于该方法参数选取适当,气流组织、损失考虑、速度分布分析得当,因而设计出的透平膨胀机达到了很高的效率,值得我国借鉴。图12表7。 This article describes in detail the design method of the nitrogen turbine expander working wheel and diffuser provided by NREC Company to APCI in the United States. Due to the proper selection of the parameters of the method, air flow organization, loss considerations, and proper analysis of the velocity distribution, the turbine expander designed has achieved high efficiency and is worth our reference.
