船舶大间距移水系统由于阀门启闭造成的水锤冲击现象突出，严重影响到系统运行安全和总体隐身性能。为指导移水系统水锤冲击治理，探究大间距移水水锤升压的主要影响因素，本文基于瞬变流模型，采用系统仿真的方法对关阀时间、移水压力、管道直径等影响因素进行单一变量的比对计算，计算结果表明延长关阀时间、降低移水压力、增大管道直径可有效降低水锤升压。研究结果为大间距移水系统的水锤冲击治理指明了方向。
The water hammer impact caused by the opening and closing of valves in a large distance water transfer system of a certain type of warships is prominent, seriously threatening the safety of system operation and overall stealth performance. To guide the treatment of water hammer impact in water transfer systems and explore the main influencing factors of large spacing water hammer pressure increase, the paper used system simulation method to compare and calculate single variables of factors such as valve closing time, water transfer pressure, and pipeline roughness, based on transient flow model. The calculation results showed that extending valve closing time, reducing water transfer pressure, and increasing pipeline diameter can effectively reduce water hammer pressure increase. The research results pointed out the direction for the treatment of water hammer impact in large spacing water transfer systems.
