⑴超声波换能器返潮。一般用兆欧表定期检查换能器相互连接的电源插头，查验换能器正负间的绝缘电阻值可以分辨。一般规定绝缘电阻超过30兆欧以上。假如达不了这一绝缘电阻值，很可能是换能器返潮。检修办法是把换能器总体（不包括静电喷塑机壳）放入烘干箱设置100℃上下，烘干处理三小时或是应用吹风机去潮电阻值正常的才行。换能器振子点火，结构陶瓷断裂。检修时可以用人眼和兆欧表融合查验。一般做为应急处理的对策，可以把某些毁坏的换能器断掉，不容易干扰到其他换能器正常的应用。

⑴ The ultrasonic transducer returns to moisture. Usually, a megohmmeter is used to regularly check the power plugs connected to the transducers, and the insulation resistance value between the positive and negative terminals of the transducers can be distinguished. It is generally stipulated that the insulation resistance should exceed 30 megaohms or more. If the insulation resistance value cannot be reached, it is likely that the transducer has returned to moisture. The maintenance method is to place the entire transducer (excluding the electrostatic spray molding machine casing) in a drying oven set at around 100 ℃, dry for three hours, or use a hair dryer to remove moisture until the resistance value is normal. The transducer oscillator ignites and the structural ceramic fractures. During maintenance, a human eye and a megohmmeter can be used for fusion inspection. As a general emergency response measure, some damaged transducers can be disconnected to prevent interference with the normal application of other transducers.

⑵换能器开胶。我们知道大部分生产厂家选用粘胶的方法固定不动换能器，但超声波清洗机的长久应用后因为震动会出现开胶状况。也是有生产厂家选用粘结加螺丝拧紧的方法，一般情形下不容易发生开胶，因为螺丝的功效，振子开胶后不易从震动表面落下来，一般的分辨方式是用手轻摇振子的尾端，认真观察震动面的强力胶状况进行分辨。

⑵ Glue the transducer. We know that most manufacturers use adhesive to fix the fixed transducer, but after long-term use of ultrasonic cleaning machines, the adhesive may open due to vibration. There are also manufacturers who choose the method of bonding and tightening with screws. Generally, it is not easy to open the adhesive because of the effectiveness of screws. After opening the adhesive, the vibrator is not easy to fall off the vibration surface. The general way to distinguish is to gently shake the tail end of the vibrator by hand and carefully observe the strong adhesive condition on the vibration surface.

⑶一般振子发生开胶之后超声波开关电源输入输出的效率正常的，可是因为振子与震动面联接不太好，震动面的振动实际效果不太好，长期后因为动能不能释放出来出来，很可能会烧毁振子。振子开胶针对使用者而言检修起来是非常繁琐的，一般状况只有送到生产商开展检修。防止振子开胶有效的办法是日常应用中留意不碰撞震动面。

The efficiency of the input and output of the ultrasonic switch power supply is normal after the opening of the oscillator, but due to poor connection between the oscillator and the vibration surface, the actual vibration effect of the vibration surface is not very good. In the long run, the oscillator may be burned due to the inability to release kinetic energy. For users, the maintenance of the oscillator glue opening is very cumbersome, and in general, it can only be solved by sending it to the manufacturer for maintenance. An effective way to prevent the oscillator from opening is to pay attention not to collide with the vibrating surface in daily applications.

⑷震动面破孔。一般超声波换能器超负荷应用多年之后很有可能会产生震动面破孔的状况，这也是因为震动面的不锈钢板材长期高频率震动疲惫而致，震动面破孔表明换能器的使用期限早已到了，检修上一般只有拆换。

(4) Vibration surface perforation. After years of overloading application, ultrasonic transducers are likely to have holes on the vibration surface, which is also caused by long-term high-frequency vibration fatigue of the stainless steel plate on the vibration surface. The holes on the vibration surface indicate that the service life of the transducer has long expired, and maintenance usually only involves disassembly and replacement.
