The first is the transducer moisture, resulting in the transducer can not work properly. Secondly, the transducer degumming problems, resulting in the phenomenon may be on the one hand, long-term use of ultrasonic cleaning machine vibration degumming reasons, on the other hand, may be the transducer material problems. In addition, the vibrator degumming, stainless steel vibration surface perforation is also prone to transducer failure.
