1) The ultrasonic transducer is damp. Generally, a megohm meter is used to check the plug connected with the transducer, and the insulation resistance value between the positive and negative electrodes of the transducer can be judged. Generally, the insulation resistance is required to be greater than 30 megohm. If this insulation resistance value is not reached, it is likely that the transducer is affected by moisture. The maintenance method is to put the transducer as a whole (excluding the spray shell) into the oven to set about 100 ° C, dry for three hours or use a hair dryer to remove moisture until the resistance value is normal.
2) The transducer vibrator ignites, and the ceramic material breaks. Maintenance can be checked with the naked eye and megohm meter. Generally, as an emergency treatment measure, the individual damaged transducer can be disconnected, which will not affect the normal use of other transducers.
3) Transducer degumming. We know that most manufacturers use adhesive to fix the transducer, but after long-term use of ultrasonic cleaning machine due to vibration will appear degumming phenomenon. There are also manufacturers using cementation screw fastening method, under normal circumstances will not appear degumming, due to the role of screws, the vibrator degumming will not fall from the vibrating surface, the general judgment method is to gently shake the tail of the vibrator, carefully observe the glue situation of the vibrating surface to make a judgment. Generally, the output power of the ultrasonic power supply is normal after the oscillator appears degluing, but because the oscillator and the vibration surface are not well connected, the vibration effect of the vibration surface is not good, and the energy can not be released after a long time, it is likely to burn the oscillator. Vibrator degumming is more troublesome for the user to maintain, and in general, it can only be returned to the manufacturer for maintenance. The most effective way to avoid oscillator degumming is to pay attention not to hit the vibration surface during normal use.

4) Vibration surface perforation. General ultrasonic transducer full load after several years of use may appear vibration surface perforation, this is due to the vibration surface of stainless steel plate long time high-frequency vibration fatigue caused by vibration surface perforation indicates that the service life of the transducer has arrived, maintenance can only be replaced.
