When following the se-recommendations, you should obtain an ideal surface for seal sliding surfaces (Fig.3).理想的密 封件滑动面。 If a surface is too “smooth” (Fig. 4), it has only very small pockets in which to retain the lubricant. The lubricant is wiped off the seal lip because there is not enough texture to keep the lubricant in place, which results in in sufficient lubricating film and increased wear of the seal lip and its opposing body.太光 滑，几乎没有空间储存润滑剂，不能形成润滑膜，加剧密封件磨 损。 A surface that is too rough (Fig. 5), on the other hand, has a direct negative impact on the surface of the seal lips which is worse when subjected to reciprocating motion.太粗糙了，在往复 运动时，密封件的边缘会产生内磨擦。 2009 Shine Wu Tribological aspects in pneumatics 8/18 表面光洁度 在课堂上，老师拿了一个玻璃杯，里面放了一个大石头，差 一个学生回答：没满，还可以放沙子。 待学生放完沙子，老师又问：满了吗？ 全班同学回答满了，有一个男孩却回答 满了吗？ 没满。如果加压，可以压进一些气体。 2009 Shine Wu Tribological aspects in pneumatics 9/18 润滑剂的选择 2009 Shine Wu Tribol
