加油系统的管网布置对水力瞬变的影响

The Influence of the Network Layout in Refueling System on Hydraulic Transient

以机场加油系统管网为例,针对环状管网和枝状管网的特点分别建立了水力瞬变数学模型,并采用特征线法对不同布置的加油系统管网进行了水力瞬变数值模拟,实例模拟结果表明环状管网比枝状管网的水力瞬变压力峰值低,且管道各部分的压力较为均衡,稳定性和可靠性较好,可有效减弱水力瞬变的破坏和影响。因此,机场加油系统更适合采用环状管网。

With the example of airport refuel system network, aiming at the characteristics of loop pipe network and dendritic pipeline network, hydraulic transient mathematical model was set up respectively. And use characteristic method to simulate different arrangement of refuel system network of hydraulic transient, the examples simulation results show that hydraulic transient peak pressure of loop pipe network is lower than dendritic pipeline network,and the pressure of each parts of pipeline is even more equilibrium,and stability and reliability of pipeline is better, it can decrease effectively the destruction of hydraulic transient and the effects. Therefore, the using of loop pipe network is more suitable at airport refuel system network.
