| 摘 要： | 分析一种直线往复压缩机连杆油封在振动及摇摆环境下的密封失效原因,指出其故障根源来自于油封唇口的椭圆应变以及往复迟滞行为,对此采取了相应的措施:设置刚性随动套以保证油封唇口的圆度周正,设置限移环片以改善油封唇口的跟随性。经试验证实,上述改进措施明显提高了连杆油封的密封效果,达到了预期的目标。

| Abstract: | The causes of sealing failure of a connecting rod oil seal for a straight line reciprocating type compressor were analyzed,it was pointed that the main failure reasons in vibrating and rocking conditions were occurred from the seal lip's elliptical strain deformation and reciprocating hysteresis behavior.Some appropriate measures were adopted:to set rigid follower sleeve to ensure the seal lip roundness,to set the limit moving ring to improve the seal ring lip's following performance.The test confirms that ... |
