成品油顺序输送交替过程中摩阻损失的计算

在管道输送成品油过程中,沿线压力的变化主要是由管道特性的变化和不同密度油品在管道中交替产生的,某时刻管道的流量将由各站间供能(启泵方案)、耗能(沿程阻力)以及高程决定。随着混油段的移动,管内流量必然会发生变化。结合实例,对不同油品在管道中交替时摩阻损失随时间的变化进行了计算和分析。

Calculation and Analysis of Frictional Resistance in the Batch Transportation

In multi-product pipelines, the pressure changes along the pipeline is mainly caused by the change of pipeline characteristic and products with different densities within the pipeline,the flow varies with time, which is decided by the pumping number, resistance and elevation. The variation of flow must generate with the movement of mixed contamination plug in the pipeline. In the paper calculation and analysis on the change law of frictional resistance along pipeline produced from different products with different densities for the pipeline have been made with hydraulic calculation equations combined with the case.
