在减速顶的设计、生产、使用与维修过程中,密封是一个极重要的问题。它不仅关系到产品的生产成本和竞争能力,而且还直接影响到产品的性能、寿命、维修周期。 影响密封装置密封能力的因素有很多。如:密封元件的性能与加工精度,密封表面的表面质量,被密封介质的性能,外部参数(温度、压力差、法向载荷等)。 Seal in the design, production, use and maintenance process, the seal is a very important issue. It is not only related to product cost and competitiveness, but also directly affect the performance of products, life expectancy, maintenance cycle. There are many factors that affect the sealing ability of the seal. Such as: sealing element performance and processing accuracy, the surface quality of the sealing surface, the performance of the medium being sealed, external parameters (temperature, pressure difference, normal load, etc.).
