On the base of linear velocity method, a novel method for making equivalent PV diagram at the cold end in a pulse tube refrigerator has been proposed. It is simple and it can also be easily used. 在脉管制冷机线性气流速度分析法的基础上,提出了一种新颖的脉管制冷机等效PV图制作方法,该方法直观、简便、宜于使用。
The validity to carry out condition monitoring and fault diagnosis of reciprocating compressor with the pV-Diagram is further verified by means of the analysis for the pV-Diagrams. 通过对指示图的分析进一步证明了用指示图对压缩机运行工况进行监测和故障诊断的有效性。
