摘　　要：装在电液伺服机构产品蓄能器活塞上的密封圈,既要保证蓄能器气体的密封性,又要保证液压油的密封性。密封圈在使用前应进行气压筛选,以剔除质量差的密封圈,保证蓄能器正常工作。该文针对气压筛选的全过程进行介绍,对气选后密封件的物理性能进行检测和分析,给出了比较合理的气压筛选试验的参数及气选后密封圈合格判定标准,供电液伺服机构工艺设计时参考。The seal assembly on the electro-hydraulic servo mechanism＇s accumulator of piston, must assurance the accumulator gas tightness and hydraulic oil tightness. The seal should be to do the selection of air pressure experiment befor in use, and removel the quality defect seal, to assurance the accumulator＇s operational condition. This arctile introduce the processe of the selection of air pressure, detection and analysis the seal＇s physical properties, Obtained the parameter for the selection of air pressure experiment and the qualification determinant for seal after experiment, provide reference for electro-hydraulic servo mechanism process design.
