摘　　要：采用电涡流位移传感器对整体石墨密封环和镶装式石墨密封环的端面压力变形进行试验研究,分析石墨环结构和加工工艺对密封端面压力变形的影响。试验结果表明,密封压力使石墨环密封端面产生了负锥度变形;镶装过程使镶装式石墨环底面产生的径向和周向变形会导致密封端面产生较大的压力变形;对镶装式石墨环端面的精加工处理可有效抑制石墨环的端面压力变形。The pressure deformation of unitary carbon seal ring and mounted carbon seal ring was experimental studied using an eddy current displacement sensor. The effects of seal structure and processing technology of carbon seal ring on pressure deformation were analyzed. The experimental results show that the deformation of sealing face caused by sealed pressure is in negative conicity. The deformation of carbon seal ring underside caused by mounted structural element can lead to large pressure deformation of sealing face. The precision work can evidently reduce the pressure deformation of sealing face.
