【摘要】 在管道漏油与压力降落关系理论基础上,利用泰勒公式得出了一定流态下,反映输油管道压降变化率与漏油量/输油量、漏油点以及管道始终端高程差间的关系式,揭示了输油管道系统外生变量(漏油点、高程差)与内生变量(流量、压降)间的相互作用规律,放大了输油管道系统压力变化对漏油示警的盲区。更多还原

【Abstract】 Based on theory of oil pipeline leak quantities and it s pressure drop,the relations among the rate of change of oil pipeline pressure drop,oil leak or oil transporting quantities and the position of taking place oil leak,as well as the difference of elevation of pipeline start-end,were given using Thaler equation.It is the relation between exogenous variables(place of leak oil,the difference of elevation of pipeline start-end)and endogenous variables(flow,pressure drop)that amplifies the blind range of warning oil leak using pressure drop.更多还原
