气囊式蓄能器气体多变指数值域的研究

Study of range of air polytropic exponent value for bladder accumulator

为合理选择蓄能器多变指数取值,应用热力学基本原理,分析了气囊式蓄能器的热力学性质和影响多变指数实际取值的各种主要因素,指出了气囊式蓄能器气体多变指数的值域范围为1-1.4;同时应考虑实际用途和工况。

For the reasonable selection of air polytropic exponent value, with basic principle of thermodynamics, the thermodynamic property of bladder accumulator and main influence factors were analyzed in detail.According to the practical use and working conditions of bladder accumulator, the range of air polytropic exponent value for bladder accumulator showld be 1-1.4.
