介绍了依据 2D12压缩机的结构特点而开发研制的气缸内压力引出装置。此装置安装方便 ,对压缩机的余隙容积影响较小 ,人造故障试验验证了此装置的可靠性及结构的合理性 ,并用试验采集的压力信号绘制出了指示图。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。
According to the structural characteristics of 2D12 compressor developed by the introduction of pressure within the cylinder device. The device is easy to install and has little impact on the clearance volume of the compressor. The artificial fault test verifies the reliability and the reasonable structure of the device, and maps the pressure signals collected by the test. Through the analysis of the indication chart, it further proves the effectiveness of using the indicator diagram to monitor and diagnose the operating condition of the compressor.
