深井水泵的旋轴和泵座轴瓦间的密封称为轴封。轴封的密封作用是通过填料压盖压紧填料(盘根),迫使填料在填料腔内沿径向变形封闭径向间隙来实现的,其结构如图一所示
Deep well pump shaft and pump seat bearing seal between the shaft seal. The sealing function of the shaft seal is to compress the packing (packing) through the packing gland, forcing the packing to be radially deformed in the packing cavity to close the radial clearance, and the structure is as shown in the figure
