武汉—信阳成品油管道顺序输送中的压力变化和控制方法

The Pressure Changes in Wuhan——Xinyang Oil Product Pipeline of Sequential Transportation and Control Method

以武汉—信阳成品油管道为例,对大落差管道油品顺序输送中的压力变化和控制方法进行了研究分析,利用水力计算公式计算水力特性,分析进出站的压力变化,结合实例,对不同油品在大落差管道中交替时沿线的压力变化规律做了定性和定量的分析,提出了在混油界面翻越点的压力控制措施,以保证管道安全、平稳、高效的运行。

Taking the Wuhan—Xinyang oil product pipeline as an example, the pressure changes in large- fall pipeline of sequential transportation and control method were analyzed. The hydraulic characteristics were calculated using hydraulic formula, and the pressure changes at the entrance and exit of stations were analyzed. Combining with the example,the change law of pressure along pipeline during alternating of different oils in the large 一 fall pipeline was analyzed qualitatively and quantitatively, and the pressure control measures at the mixed oil interface crossing point was proposed to ensure safe,stable, efficient operation of pipeline.
