摘要
通过对焦化装置辐射进料泵机械密封的技术改造,解决了高温热油泵机械密封运行寿命短的问题;并且消除了原来密封结构出现密封失效,引起高温热油直接泄漏到大气中引发火灾的隐患。
Technical modification was made to mechanical seals of radiant feed pump of the Coking Unit.This modification solved the problem of short service life of high temperature hot oil pump's mechanical seals,and also eliminated the hidden fire hazard caused by high temperature oil leaking directly to atmosphere because of seal failure happened in the original seal structure.
