“转盘装置”简介一、基本原理气蚀是一种复杂的水动力学现象,即在流动的液体中,当某处压力降低到该处气化压力以下时,就会发生气蚀现象。当气穴气泡流动到高压区突燃被压缩而在接近固体表面溃灭时,将发生复杂的作用而导致材料破坏。由于气蚀机理目前尚未完全摸清,普遍看法认为是由于气穴气泡溃灭时连续产生高频冲击致使材料疲劳破坏,其中也伴有化学 Brief introduction of “turntable device” I. Basic principle Cavitation is a complex hydrodynamic phenomenon, that is, cavitation occurs when the pressure in a flowing liquid drops below the gasification pressure there. As cavitation bubbles flow into the high-pressure zone, the flare is compressed and collapses near the solid surface, a complex effect occurs that causes the material to break. As the mechanism of cavitation has not yet fully understood, the general view is that due to the collapse of cavitation bubble continuous high-frequency impact resulting in material fatigue damage, which also accompanied by chemical
