摘　　要：分析了化工系统中80Y60焦油沥青泵原机械密封易于损坏的原因,提出了将原机械密封改为盘根密封,并介绍具体的改进方法。实际运行表明,该改进方法解决了沥青泵原机械密封频繁更换的问题。The failure of the mechanical seal of 80Y60 asphalt pump of chemical system was analyzed. The improvement measure that replaces the mechanical seal with packing seal was put forward. The practical result shows that the service life of asphalt pump seal is prolonged.
