动密封技术的应用领域非常广泛。凡有一定压差和密封要求的传动部件都有动密封问题。在石油化工、原子能、医药卫生、食品、冶金、造船、航空、真空、低温等领域中,动密封性能不好不仅会使工艺技术指标难以达得,而且有可能造成环境污染和安全事故。因此,动密封件的“滴水不漏”一直是这些领域的人们密切关心的课题之一。
Application of dynamic sealing technology is very wide. Where there is a certain pressure and sealing requirements of the transmission parts have a dynamic seal problem. In the fields of petrochemicals, atomic energy, medical and health, food, metallurgy, shipbuilding, aviation, vacuum, low temperature and other fields, the bad performance of dynamic sealing not only makes the technical index difficult to reach, but also may cause environmental pollution and safety accidents. Therefore, the dynamic seal of the “drip” has been one of the topics closely concerned by people in these fields.
