在有压管道中,由于某种原因使得水流速度发生突然变化,从而引起管内压强急剧升高或降低的交替变化,并以波的形式在管中往返传播,进而形成“水击”。因其发出的声音如锤敲击管道,所以也称之为“水锤”。一、水击的现象1.水击时会发出如锤击管道的“咔咔3声;2.管道强烈震动,严重时引起管道破坏,接头处螺纹损坏,阀门设备损坏。二、原因分析 In pressurized pipelines, for some reason, the water flow rate changes abruptly, which causes an alternating change in the pressure inside the tube that rises or falls sharply, and propagates back and forth in the tube in the form of waves, thereby forming a “water hammer”. Because of its sound, such as a hammer hit the pipe, it is also called “water hammer.” First, the phenomenon of water hammer 1. When the water hammer will be issued as hammering the pipe, “3” sound; 2. The pipe is strongly shaken, causing serious damage to the pipe, thread damage at the joint, damage to the valve equipment. Second, the cause of the analysis
