船舶泵阀移水系统水锤抑制方法研究

通过Flowmaster瞬态仿真分析,对船舶泵阀移水系统水锤抑制方法进行研究。结果表明,阀快速关闭时,系统中存在明显的水锤现象;延长阀关闭时间和采用两阶段关闭的策略,可以有效地抑制系统水锤冲击;阀离泵组越近,对水锤抑制效果越好;管路中加装蓄能元件也能有效抑制水锤。

Research on method of water hammer suppression for marine moving water system by pump and valves

The method of water hammer suppression of the marine moving water system by pump and valves wasstud-ied through transient simulation analysis of Flowmaster. The results show that when the valve is closed rapidly, there is an obvious water hammer in the system. Extend the valve closing time and the two stage closure strategy can be used toeffect-ively suppress the impact of water hammer in the system; the closer of control valve from the pump, the water hammersup-pression effect was better. Pipeline installation of energy storage components can also effectively inhibit the water hammer.
