反应釜机械密封失效分析及改造

ANALYSIS ON REACTOR MECHANICAL SEAL FAILURE AND MODIFICATION

针对丁辛醇装置的3台反应釜搅拌器频繁出现机械密封泄漏、釜体振动大等问题,从搅拌器结构和机械密封结构进行分析,认为是设备结构原因导致问题发生,通过改变底部轴承材质、重新对轴承座找中心以及改造机械密封等措施,有效地降低了设备维修频率,保障了装置平稳运行。

Mechanical seal leakage frequently occurred in three(3) reactors′ agitators in octanol plant, and reactor body vibrated greatly. Analysis on reasons pointed to the structure of agitator and mechanical seal. By changing the bearing material at the bottom, realigning the bearing pedestal and modifying mechanical seal, the frequency of equipment maintenance was greatly reduced, ensuring the plant operation steadily.
