波纹管在使用过程中,其刚度或弹性会慢慢减小,这种弹性减小的现象通常称之为失弹。实验和实际应用表明当波纹管的失弹量超过设计初始压缩量的18%一20%时,整个波纹管机械密封就会发生泄漏。金属波纹管机封排列5缩水过滤工具在温度低于200℃时失弹现象不明显,但在高温(超过300℃)下使用,开车后泵很快就发生泄漏,将使用的机封拆下测盆发现金属波纹管组件高度较安装前平均降低2一3mm。波纹管失弹主要由于永久变形或应力松弛,还有一种情况是工作介质结晶沉淀或凝固在波纹管的缝隙中,使波纹管变形能力减小或丧失变形能力。因此,高温和载荷是造成波纹管失弹的主要原因。

通常,将失效的机封拆下检查发现石墨密封环磨损严重。通过分析和试验发现,金属波纹管机封的端面比压受波纹管的有效直径的影响,而有效直径是随压力的变化而改变。当波纹管受外压,其有效直径随压力的加大而逐渐缩小;当波纹管受内压,其有效直径随压力的加大而逐渐加大。由于压力过大,导致摩擦副摩擦严重,石墨环过度磨损引起泄漏。图9一5所示为某厂减压塔底泵石墨密封环端面的磨损磨蚀情况。
