摘　　要：一般采用气体流量计前加装缓冲器消除压缩机性能试验装置中气流脉动对测量精度的影响。本文分析2种适用于大型活塞式压缩机性能试验装置的缓冲器容积的计算方法,认为针对压缩机性能试验装置中的微小脉动气流,德国BORSIG的计算方法更加适合。搭建大型活塞式压缩机性能试验装置,利用经理论计算设计的缓冲器进行试验,发现即使在最大测试流量的情况下,缓冲器仍然可以很好地削减气流脉动的影响,从而大大提高压缩机试验装置的试验精度。In order to avoid the impact of the compressor test device＇s airflow pulsation on the measurement accuracy,the gas buffer is usually installed in front of gas f｜owmeter. Two calculation methods of gas buffer＇s volume are analyzed. The result shows that the Germany BORSIG＇s calculation method is more suitable to the micro airflow pulsation in compressor test device. The compressor performance test device with the gas buffer de- signed by theoretical calculation is build. It is found through experiment the buffer can re- duce the impact of airflow pulsation effectively even at the maximum gas flow. The meas- urement accuracy of the compressor test device can be improved greatly.
