【摘要】 空化是指在负压的作用下,在液体中形成空穴或空化泡的现象;空化强度则用以衡量液体介质中空化活动的剧烈程度。当发生空化时,液体介质中会产生空化噪声。空化噪声成分复杂,各部分由不同空化泡的活动与状态产生,其中包含了大量的信息。本文介绍了利用测量、分析空化噪声来确定超声清洗设备中的空化强度的优点,以及具体的测量方法。更多还原

【Abstract】 cavitation refers to the formation of cavities or bubbles in liquid under the action of negative pressure; cavitation intensity is used to measure the intensity of cavitation activity in liquid medium. When cavitation occurs, there will be cavitation noise in the liquid medium. The components of cavitation noise are complex. Each part is generated by the activity and state of different bubbles, which contains a lot of information. This paper introduces the advantages of using measurement and analysis of cavitation noise to determine the cavitation intensity of ultrasonic cleaning equipment, as well as the specific measurement methods.更多还原
