摘　　要：从橡胶密封件的密封原理出发,分析了由于密封结构形式选择不当、结构设计不合理和密封材料使用不当造成的密封失效案例。结果表明,液压系统的密封失效原因是复杂的,需结合设计和材料,才能解决各种密封失效问题,提高橡胶密封的可靠性。From the point of sealing principle of rubber parts, some cases about the sealing failures, such as improper selection of structure formation, unreasonable design of structure and incorrect use of sealing materials were analyzed. The results showed that the reasons of sealing failure were complex. The problems of sealing failure can be solved by combining design and material to improve the reliability of rubber sealing products.
