水锤是由于管道中的水流速度突然减小或停止而产生的一种压力波动。普遍认为水锤这种压力波动产生的强烈冲击,足以造成管道系统的振动和破坏。水流的突然停止经常引起某种程度上的有声的或无声的冲击,因此,没有声音并不 Water hammer is a kind of pressure fluctuation caused by a sudden decrease or stop of the water flow velocity in the pipeline. It is generally accepted that the strong impact of pressure fluctuations such as water hammer is sufficient to cause vibration and damage to the piping system. Sudden stops in water flow often cause some audible or silent impact, so no sound is not
