摘要
分析了影响自紧式金属O形环密封性能的因素,通过O形环结构设计、密封槽尺寸优化及表面粗糙度工艺控制、O形环装配工艺改进,成功完成了某项目从178mm^1 052mm 5种规格双O形环密封承压容器的水压试验,验证了该设备密封结构的可靠性,为类似密封结构的设计及工艺实现提供经验借鉴。
Factors influence sealing behavior of self-tightening metal O-ring was analyzed. Hydrostatic test on pressure vessel whose sealing grooves ranged from Ф 178 mm to Ф 1 052 mm was successfully conducted based on O-ring design, dimension optimization of sealing grooves, sealing surface roughness control, process control during O-ring assembling. Sealing reliability was verified and experience for structure design and process achievement was supplied.
