摘要/Abstract

摘要： 当输油管道某点突然发生堵塞，堵塞处将出现瞬态压力突变，堵塞上、下游处分别形成一增压波和减压波，并以一定的速度向堵塞点上、下游两端传播。通过建立管道堵塞水力瞬变模型，利用Ｖｉｓｕａｌ　ｃ＋＋６．０编写堵塞水力特性分析程序，取特定的案例，对案例中管道不同堵塞面积引起的水力瞬变特性进行了模拟。分析模拟结果，得出了不同的堵塞面积对管道的压力、流量等水力特性的影响。

Abstract: When jams happen to a oil pipeline suddenly, transient pressure mutations will appear in the blocked pipe. It causes a pressurization wave and a decompression wave which respectively spread to the upstream and the downstream at a certain speed. Through establishing hydraulic transient model of pipe jams, using Visual c++ 6.0 to program the characteristics analysis program of jams hydraulic, taking specific pipeline, the characteristics of transient hydraulic which was caused by different jams acreage was simulated. The simulated results show that pressure and flow rate is affected by the different jams acreage. 
