摘　　要：以某滚动转子式压缩机为研究对象,基于润滑油粘性润滑原理和制冷剂泄漏的功率损失理论计算与试验验证数据,利用相关性理论开展制造过程装配间隙配对与分档对性能影响的相关性分析,获得主成分贡献率分布及其载荷矩阵,发现第1-4主成分的累计贡献率达71.1%,影响制冷剂内泄漏的主要有泵体组件机械驱动精度与效率、泵体同心精度与容积率、平面精度与摩擦功耗,对制冷剂内泄漏导致的制冷量损失的贡献分别为33%、21%与17.1%,并据此得到压缩机泵体关键零件的过程关键装配参数与控制方案。Taking a rolling rotor compressor as the research object, based on the theory of lubricating oil viscous lubrication and the power loss of refrigerant leakage theoretical calculation and experimental verification data, using the correlation theory to carry out the correlation between the assembly gap matching and binning in the manufacturing process and the performance impact analyze, obtain the principal component contribution rate distribution and its load matrix It was found that the cumulative contribution rate of the first 1-4 main components reached 71.1%. The main factors affecting the leakage of the refrigerant are the mechanical drive precision and efficiency of the pump body assembly, the concentric accuracy and volume rate of the pump body, the plane accuracy and the frictional power consumption, and the impact on the refrigerant. The contribution of the cooling capacity loss caused by internal leakage is 33%, 21% and 17.1% respectively. And obtain the process key assembly parameters and control schemes of the key parts of the compressor pump body.
