此资料可作为油封设计及密封唇材料选择的参考。在温度高达70℃时,此资料的附表均有效。装置油封的十条规则1.旋转轴应与油封孔同心才能得到最大的密封效果。但应适应微小的配合公差。2.密封的效率及寿命由密封唇接触轴的光洁度决定。轴必须磨光。在一般应用上,不超过25微时的光洁度将得到满意的结果。在高速及高压的情况下,8至12微时的光洁度将得到较长的寿命。(注:25微时的光洁度相当于▽_7以上,8—12微时的光洁度相当于▽_8以上)。
This information can be used as a seal design and sealing lip material selection reference. The data sheet is valid at temperatures up to 70 ° C. Ten rules for installing the oil seal 1. Rotary shaft should be concentric with the oil seal to get the maximum sealing effect. But should be adapted to the tiny tolerances. 2. The efficiency and life of the seal is determined by the finish of the seal lip contact shaft. Shaft must be polished. In general applications, no more than 25 micro-minute finish will be satisfied with the results. In high speed and high pressure conditions, 8 to 12 micro-minute finish will get a longer life expectancy. (Note: 25 micro-hours of the finish is equal to ▽ _7 or more, 8-12 micro-hours of the finish equivalent to ▽ _8 or more).
