The ultrasonic transducer mainly consists of an ultrasonic signal generator and a cleaning tank. The ultrasonic signal generator generates high-frequency oscillation signals, which are converted into high-frequency mechanical oscillations of tens of thousands of times per second by the transducer. In the cleaning liquid (medium), ultrasonic waves are formed and radiated and propagated in the cleaning liquid in a high-frequency alternating manner of positive and negative pressure. 1. De-bonding of the oscillator Our transducers are guaranteed by a dual process of bonding and screw fastening. This situation usually occurs. Perforation of the stainless steel vibration surface: Generally, when ultrasonic transducers are used at full load for 10 years, perforation of the vibration surface may occur. If the ultrasonic transducer vibrator sparks and the ceramic material breaks, it can be inspected by combining the naked eye and a megohmmeter. Generally, as an emergency measure, the individual damaged vibrator can be disconnected without affecting the normal use of other vibrators. 2. If the ultrasonic transducer gets damp, a megohmmeter can be used to check the plug connected to the ultrasonic transducer. By checking the insulation resistance value, the basic situation can be determined. Generally, the insulation resistance should be greater than 5 megohms. If the insulation resistance value cannot be reached, it is generally because the transducer is damp. The entire transducer (excluding the powder-coated shell) can be placed in an oven set at around 100℃ for drying for 3 hours, or a hair dryer can be used to remove the moisture until the resistance value returns to normal. 3. Generally, after the vibrator experiences delamination, the output power of the ultrasonic power supply remains normal. However, due to poor connection between the vibrator and the vibration surface, the vibration effect of the vibration surface is not good. Over a long period of time, as the energy cannot be released, the vibrator is very likely to be burned out. The delamination of the oscillator is rather troublesome for users to repair. Generally, it can only be sent back to the manufacturer for maintenance. The most effective way to prevent the vibrator from delaminating is to be careful not to strike the vibration surface during normal use. 4. Perforation of the vibration surface. General < a href = "http://www.kejeme.com/news/xyxw/1470.html" > < strong > ultrasonic transducer replacement < / strong > < / a > full use several years later may appear vibration plane punch, This is due to the fatigue of the stainless steel plate on the vibrating surface caused by long-term high-frequency vibration. Perforation on the vibrating surface indicates that the service life of the transducer has come to an end. In maintenance, it is generally only possible to replace it
