the generation mode of ultrasonic cleaning machine can be selected according to different cleaning purposes. Currently, the commonly used ultrasonic cleaning machine is the continuous oscillation mode that can perform powerful cleaning. Frequency modulation and multi-frequency methods often result in uneven cleaning during the cleaning process and are not very suitable for cleaning heavily contaminated objects. Characteristics of continuous oscillation mode: Continuous oscillation, fixed amplitude and frequency, capable of powerful cleaning. If the vibration wave effect causes uneven cleaning, the shaking should be increased to achieve uniform cleaning. It features widened modulation, amplitude variation, excellent degassing effect, good cleaning performance for various objects, but generates a lot of noise. Frequency modulation (FM oscillation), with oscillation frequencies varying by several thousand Hertz, can achieve uniform cleaning. Poor cleaning efficiency and low average output power. When multiple frequencies occur simultaneously, a balanced sound field is formed, ensuring uniform cleaning and making it difficult to obtain strong ultrasonic waves. In multi-frequency alternation, each frequency generates multiple frequency cleaning equilibria, making it difficult to achieve powerful cleaning. The conical radiation cleaning uses a stainless steel resonator for ultrasonic radiation. Generally, when used in situations where cleaning is not thorough, it can achieve 10 or 20 times the intensity of a conventional ultrasonic cleaner, with high performance. But the cleaning surface is small and the noise is high.
