通过实验,研究影响离心泵泵内圆盘摩擦损失的主要因素,探讨了轴向间隙、介质粘性、盖板表面粗糙度对圆盘摩擦损失的影响,实验证明,此三者的增大都会导致圆盘摩擦损失的增加. Through experiments, the main factors that affect the frictional loss of the inner disc of a centrifugal pump are studied. The influences of the axial clearance, the viscosity of the media and the surface roughness of the disc on the friction loss of the disc are discussed. Experiments show that the increase of these three leads to Disk friction loss increases.
