密封圈广泛地用于各种机械中,特别是用于液压机械中,起着油封作用。O型密封圈已经标准化、系列化了。并有专门工厂生产供应。设计人员可以直接查找机械设计手册选用即可。而异型密封圈则不然,没有标准,也没有专门厂家生产。如用到时,必须由设计者自己设计与制造模具,然后到橡胶厂去模压成型才行。异型密封圈模具的设计与制造比O型的复杂得多。因此,设计模具时必须考虑周全,否则将达不到你所预期的目的。方型密封圈就是属于异型的一种。
Seals are widely used in a variety of machinery, especially for hydraulic machinery, plays the role of oil seal. O-ring has been standardized, serialized. And a special factory production and supply. Designers can find the mechanical design manual can be used directly. The special ring is not the case, there is no standard, there is no specialized manufacturer. If used, the designer must design and manufacture of molds, and then to the rubber factory to molding. Special-shaped seal ring mold design and manufacture much more complex than the O-type. Therefore, the mold design must be thoughtful, otherwise it will not achieve your intended purpose. Square ring is a type of abnormal.
