超声波清洗器是一种方便、快速高效、安全可靠的洗涤器。它可以洗涤项链、戒指、珠宝首饰、钻石、贵重金属、金属表带、假牙、绘图仪器、医用器具以及精密机械零件等。 本文介绍一种高频率、低噪声、小功率超声波清洗器。它采用高效压电陶瓷片作为换能器,电子线路定时自动控制洗涤时间,清洗槽由不锈钢冲制而成。 一、超声波洗涤原理 超声波清洗器将频率为20～50KHz高频振荡电能经压电换能器转化为超声波振动。当超声波在液体中传播时产生空化作用,使液体形成空穴,并在汽泡消失时出
Ultrasonic cleaner is a convenient, fast and efficient, safe and reliable scrubber. It can wash necklaces, rings, jewelery, diamonds, precious metals, metal straps, dentures, drafting instruments, medical appliances and precision machinery parts. This article describes a high frequency, low noise, low power ultrasonic cleaner. It uses high-efficiency piezoelectric ceramic as a transducer, electronic circuit timing automatically control the washing time, washing tank made of stainless steel. First, the principle of ultrasonic cleaning Ultrasonic cleaning frequency of 20 ~ 50KHz high-frequency oscillation energy by piezoelectric transducers into ultrasonic vibration. When the ultrasonic wave propagation in the liquid cavitation, the formation of liquid holes, and when the bubble disappears
