摘要
旋转式压缩机正向着高速、高负载方向发展,作为泵体核心组件的叶片,其运行工况也变得越发恶劣。本文选取表面经Ni-P和氮化处理的压缩机叶片进行摩擦试验,考察摩擦时间、速度和荷载对摩擦系数及磨耗的影响;并通过SEM及EDS等分析手段分析其表面形貌、化学成分及结合强度等;最后进行性能试验以及寿命试验,分析其在旋转式压缩机上的应用可行性。
Rotary compressor is developing in the direction of higher speed and load. As a core component,the vane＇s working condition is becoming worse. Compressor vanes coa- ted with Ni P and DLC are selected for friction tests. The friction coefficient and wearing impacted by duration, speed and load are also studied. Analysis on surface topography, chemical composition and bonding strength are performed through analysis methods of SEM and EDS,etc. to investigate the different fractional behavior of relevant coating. Per- formance test and life span test are also conducted to investigate the feasibility of its appli- cation in rotary compressors.
