气蚀也叫空蚀,是水泵工作中较常见的一种现象。在水的流动过程中,由于某种原因而产生了低压区,当压力低于当时温度下水的饱和蒸气压时,水就开始汽化,形成气泡。当气泡流经高压区域时立即凝缩,产生液压冲击。在冲击点上,压力和温度急剧升高,引起强烈的噪音和振动,在附近的管壁上或其他零件的表 Cavitation, also known as cavitation, is a more common form of pump work. During the flow of water, a low pressure zone is created for some reason. When the pressure is lower than the saturated vapor pressure of water at the current temperature, the water begins to vaporize to form bubbles. When the bubbles flow through the high pressure area immediately condensed, resulting in a hydraulic impact. At the point of impact, the pressure and temperature rise sharply, causing strong noise and vibration in the vicinity of the tube wall or other parts of the table
