原油码头管道输送水击问题的研究与分析

Research and Analysis of Water Hammer Problem of Crude Oil Terminal Pipeline

原油码头卸船、原油库区装船过程当中很容易出现原油不稳定流动的现象,因此造成水击,水击对原油管道产生很严重的破坏性影响。针对大连长兴岛油船发生水击的现象进行了分析,阐述了产生水击的原因,水击的危害。提出了水击波的流速公式和不同工况时冲击压力的计算公式。最后针对工程的实际情况,从设计、施工、管理三方面提出了预防水击的措施。

Instable flow of crude oil appears very easily during crude oil ship unloading or loading,which can result in the phenomenon of water hammer,water hammer for crude oil pipeline is a devastating impact.In this paper,according to the tanker water hammer phenomenon occurred in Dalian Changxing island,reasons to cause the water hammer were analyzed as well as harms of water hammer.The velocity formula of water hammer wave was put forward as well as impact pressure calculation formula under different conditions.Finally,according to the actual situation of project,the prevention measures of water hammer were put forward from three aspects of design,construction and management.
