本文根据对实际压缩机的测试研究与对实验数据处理分析的结果,确认压力比对膨胀指数有较大的影响。同时,对某些文献介绍的膨胀指数由吸气压力来确定的方法,以及膨胀指数随压力比的变化规律,提出了不同的观点。图3表4参6。
Based on the actual compressor test research and experimental data processing and analysis of the results to confirm the pressure ratio on the expansion index has a greater impact. At the same time, different literatures put forward different viewpoints on the method that the inflation index is determined by inspiratory pressure in some literatures and the variation law of inflation index with pressure ratio.
