河北新启元蒽油加氢热油泵机械密封研究与改造

Research and renovation of mechanical seal of anthracene oil hydrogenated hot oil pump in Hebei Xinqiyuan

河北新启元能源技术开发股份有限公司蒽油加氢装置原热油泵机械密封机封使用寿命极短,达不到设计运行工况要求。通过与东莞市华汇精密机械有限公司深入交流,分析设计工况,对运行问题点进行研究改造并取得成功,实现了高温热油泵密封的长周期安全运行,取得了很好的经济效益。

The service life of mechanical seal of hot oil pump in anthracene oil hydrogenation unit of Hebei Xinqiyuan Energy Technology Development Co.,Ltd.,was very short,which couldn’t reach the designed operating condition.Through in-depth communication with Dongguan Huahui Precision Machinery Co.,Ltd.,the design conditions and operational problems were analyzed,and the research and transformation were carried out successfully.It has realized the long period safe operation of high temperature hot oil pump seal and gained good economic benefits.
