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。
Installed in the electro-hydraulic servo accumulator piston seal, it is necessary to ensure that the accumulator gas tightness, but also to ensure the sealing of hydraulic oil. Seal before use should be pressure screening, to remove poor quality seals, to ensure the normal operation of the accumulator. In this paper, the whole process of pressure screening is introduced. The physical properties of the gas seal after sealing are tested and analyzed. The reasonable parameters of the gas pressure screening test and the qualification criteria of the gas sealing ring are given. Process design reference.
