离心式压缩机多变指数的确定

Method to Determine Polytropic Exponent of Centrifugal Compressor

    摘要
  • 摘要: 以离心式压缩机多变指数为研究对象, 提出了求解方法。通过具体算例, 计算了某种组分的天然气在一定的压力、温度、多变效率下的多变指数; 分析了多变指数随温度、压力、多变效率的变化趋势, 为压缩机功率计算提供了参考依据。

     

    Abstract: Taking the polyttopic exponent of centrifugal commpressor as a research o bjective, this paper brings forward solufions.Through a case, the polytropic expoNenf of some commponent of natura l gas under certain pressure, temperat ure and polytropic efficiency is calculated.Variable current of polytropic exponent with the change of temperature, pressure and polytropic efficiency is analyzed, which provides a reference base in power calculation of compressors.
