通过不同水舱之间的调水是船舶系统中常用的浮力和姿态调整方式，通常采用水泵作为动力，通过阀门开关、切换实现不同水舱之间的调水。流体管路系统中，在阀门启闭过程中，可能出现“水锤”现象，对系统造成严重的危害。以某船舶泵阀调水系统为基础，通过台架试验研究调水过程中阀门启闭速度与管路压力波动之间的关系，实现系统技术参数的优化。结果表明，阀门启闭速度适当降低，有助于消除“水锤”效应。
Transfer water between different tanks is a common used method of buoyancy and attitude adjustment in the ship equilibrium system. Through valve switch the water transfer can be achieved, and pumps are often used as the power source. However, water hammer often occurs due to valve switch in the pipeline, which may cause serious damage to the system. Based on a pump-valve system, the relationship between valve switch speed and pressure fluctuation in the process of water diversion is experimentally studied, and the optimization of technical parameters of the system is also discussed. Experiment results show that the water hammer can be eliminated when the switching speed of valve is slow down.
