往复运动密封机理分析

往复运动密封的泄漏有三种:间隙泄漏多孔隙泄漏和粘附泄漏.本文按不同的泄漏类型对比分析了 O 形圈密封和组合密封的密封机理,对组合密封的密封机理提出了自己的见解,并得出了在往复运动密封处用组合密封优于用 O 形圈密封的结论。

Analysis of the Mechanism of Reciprocating Seals

There are three types of leakage of reciprocating seals.They are clearance leakage,Multi-Cavity leakage and sticking leakage,This paper compares and analyzes the sealing mechanism of O-rangs and that of combinedseals in the light of different types of leakage and puts torward the author's ideas on the sealing mechanism of combinedseals and comes to the conclusion that eombinedseals are superior to O-rungs in reciprocating seals.
