大落差成品油管道停输期间压力波动分析

Analysis of Pressure Fluctuation During Shutdown of Large Drop Product Pipeline

为了分析兰郑长成品油管道庆阳支线在停输过程中出现的水击现象,提高成品油管道调度运行安全,结合庆阳支线实际情况,对近几次庆阳支线在停输期间出现的压力波动现象,进行对比研究分析,得出兰郑庆阳支线停输压力安全范围提供依据,并为其他大落差成品油管道运行分析提供参考与指导。

In order to analyze the water hammer in the Qingyang branch line of Lan-Zheng-Chang oil pipeline during the shutdown process to improve the safety of oil pipeline dispatching and operation, combined with the actual situation of Qingyang branch line, the comparative re-search and analysis were done on the pressure fluctuation in Qingyang branch during pipeline shutdown in recent times, it is concluded that the Qingyang branch line of LanZhengChang oil pipeline provides the basis for the safe shutdown pressure range, which can provide refer-ence and guidance for analysis of other large drop oil pipeline operation.
