本文结合分形几何关于表面形貌的理论和等截面摩擦管内绝热流动的法诺流动模型，研究了通用型线涡旋压缩机泄漏量与啮合间隙的综合误差及粗糙表面分形维数的关系，为合理确定涡旋盘的加工精度，控制压缩机的泄漏量，提供了理论依据 In this paper, based on the theory of surface morphology and the Fano flow model of adiabatic flow in an iso-section friction tube, the relationship between the general error of leakage and meshing clearance and the fractal dimension of rough surface of a general-purpose scroll compressor is studied. Reasonable to determine the processing accuracy of the scroll, the compressor to control the leakage, provides a theoretical basis
