1、超声波清洗机的振荡器受潮：可以用兆欧表检查，其中2个引脚是超声波换能器的正极，3个引脚是换能器的负极，连接到换能器的外壳上。 检查时，2 3引脚之间的绝缘电阻值可以判断基本情况，一般要求绝缘电阻大于30兆欧以上。 如果未达到绝缘电阻值，换能器一般受潮，换能器整体（不包括喷壳）可放入烘箱设置约100米晾干3小时或用吹风机除去水分，直至电阻值正常。 （对于密封换能器，不锈钢外壳需要用手持式研磨机解剖）。
1. dampness of the ultrasonic cleaning machine oscillator: it can be checked with a megohmmeter, with 2 pins being the positive pole of the ultrasonic transducer and 3 pins being the negative pole of the transducer and connected to the outer shell of the transducer. check the insulation resistance value between pins 2 and 3 to determine the basic situation. generally, the insulation resistance is required to be greater than 30 megaohms. if the insulation resistance value cannot be reached, it is generally due to moisture in the transducer. the entire transducer (excluding the spray coated shell) can be placed in an oven set at around 100 ℃ and dried for 3 hours, or a hair dryer can be used to remove moisture until the resistance value is normal. (for sealed transducers, it is necessary to first use a handheld grinder to cut open the stainless steel casing)
2、超声波清洗机换能器振荡器着火，陶瓷材料破损：可用肉眼和兆欧表检查，一般作为应急处理措施，可断开个别损坏的振荡器，不会影响其他振荡器的正常使用。
2. ultrasonic cleaning machine transducer oscillator ignition and ceramic material breakage: can be checked with the naked eye and a megohmmeter, generally as an emergency response measure. individual damaged oscillators can be disconnected without affecting the normal use of other oscillators.
3.超声波清洗机振荡器脱胶：我们的换能器是胶结的，螺丝紧固的双重保证过程，一般不会发生这种情况，由于螺杆的作用，振荡器在脱胶后不会从振动面上掉下来，一般的判断方法是用手轻轻摇晃振荡器的尾部，仔细观察振动面的胶水情况才能做出判断。 一般来说，振荡器脱胶后超声波电源的功率输出是正常的，但由于振荡器与振动面连接不良，振动面的振动效果不好，振荡器长时间使用可能会烧坏。 振荡器脱胶的处理方法比较麻烦，只能送回厂家解决问题。 避免振荡器脱胶最有效的方法是在日常使用中注意不要冲击振动面。
3. ultrasonic cleaning machine oscillator debonding: our transducer adopts a double guarantee process of bonding and screw tightening, which generally does not occur. due to the action of screws, the oscillator will not fall off the vibration surface after debonding. the general judgment method is to gently shake the tail of the oscillator by hand and carefully observe the glue situation on the vibration surface to make a judgment. after the detachment of the oscillator, the output power of the ultrasonic power supply is normal. however, due to poor connection between the oscillator and the vibration surface, the vibration effect of the vibration surface is not good, and it may burn out the oscillator after a long time. the method of removing glue from the oscillator is quite complicated, and in general, it can only be sent back to the manufacturer for resolution. the most effective way to **oid detachment of the oscillator is to **oid hitting the vibrating surface during normal use.
4、超声波清洗机振动面穿孔：一般情况下，换能器满负荷使用数年后，可能会出现振动面穿孔，这是由于振动面不锈钢板长期高频振动疲劳所致，振动面穿孔表明换能器的使用寿命已经达到，只能更换。
4. ultrasonic cleaning machine vibration surface perforation: generally, after a few years of full load use of the transducer, vibration surface perforation may occur. this is due to long-term high-frequency vibration fatigue of the stainless steel plate on the vibration surface. vibration surface perforation indicates that the service life of the transducer has reached, and can only be replaced.
