1、换能器损坏：

1. Transducer damage:

分析：可能超声波清洗机因长时间处于开机使用状态，温度会逐渐上升导致胶体融化换能器脱落或换能器陶瓷部分断裂。

Analysis: it is possible that the ultrasonic cleaning machine is in the state of startup and use for a long time, and the temperature will gradually rise, which will cause the colloid melting transducer to fall off or the ceramic part of the transducer will break.

检测和：用摇表测量换能器的绝缘强度，绝缘强度在200MΩ以下已无法使用，须换新的换能器。

Detection and solution: use a megger to measure the insulation strength of the transducer, and the insulation strength is 200m Ω The following is no longer available and a new transducer is required.

换能器的内部陶瓷也会由于长期使用出现断裂，使其不能正常工作。

The internal ceramic of transducer will also break due to long-term use, which makes it not work normally.

2、超声波清洗器的保险损坏：

2. Insurance damage to ultrasonic washer:

在开机后如发现无电源显示，无动作，要看电源座内保险是否损坏。

If no power display and no action are found after starting, first, it is necessary to see whether the insurance in the power base is damaged.

分析：有可能是用户接地线与火线或零线混用，并没有接地(本机地线是与机器外壳相连接)，还有可能是超声波清洗机短路，元器件老化出现短路现象，导致保险损坏。

Analysis: it is possible that the user grounding wire is mixed with the fire wire or zero wire, and there is no grounding (the grounding wire of the machine is connected with the machine shell), or it may be short circuit of ultrasonic cleaning machine, and the aging of components and components may cause the insurance damage.

检测和：拿出保险观看，有无断裂，用万用表通断档测量是否断开，更换新器件。

Detection and solution: take out the fuse to see if it is broken, use the multimeter to measure whether it is broken, and replace the new device.

3、超声波清洗器的功率管损坏：

3. The power tube of the ultrasonic cleaner is damaged

分析：主板上的功率管会因为超声波清洗机长时间不间断使用或清洗液体太少长时间使用，使功率管出现短路情况。

Analysis: the power tube on the main board will be used continuously by ultrasonic cleaning machine for a long time or too little cleaning liquid for a long time, which will cause short circuit of power pipe.

检测和：当功率管在主板上连接式，用万用表测量功率管两侧管脚的阻值，正常情况下应在22Ω左右。拿下功率管后(与主板断开连接)，测量其各个管脚间应是不通的。

Detection and solution: when the power tube is connected on the motherboard, use a multimeter to measure the resistance of the pins on both sides of the power tube. Under normal circumstances, it should be at 22 Ω about. After removing the power pipe (disconnected from the main board), it is not possible to measure the pin between the pins.

4、稳压管损坏

4. The stabilizer tube is damaged

分析：稳压管的损坏一般是在功率管阻值小或短路后，开机造成的，其本身是极少损坏的。

Analysis: the damage of the regulator is usually caused by the power tube after the resistance value is small or short circuit, and it is rarely damaged.

检测和：根据二极管特性，正向导通，反向截。用万用表二极管档测量，正向阻值70Ω左右，反向∞。如数值偏差过大或正向阻值也是∞，更换新稳压管。

Detection and solution: according to the diode characteristics, forward conduction, reverse up. Measure with diode of multimeter, positive resistance is 70 Ω Left and right, reverse ∞. If the value deviation is too large or the positive resistance value is ∞, replace the regulator with a new one.

5、桥的损坏(二极管整流电路)

5. Bridge damage (diode rectifier circuit)

分析：同稳压管状况

Analysis: same as the condition of the regulator

检测和：同样根据二极管特性(桥本身就是由二极管组成)

Detection and solution: also based on diode characteristics (bridge itself is composed of diode)

6、电感、隔离变压器的损坏

6. Damage of inductance and isolation transformer

分析：由于超声波清洗机长时间工作，电感，变压器属于散热元件，其本身有可能会因温度过高而融化，烧毁，造成短路。

Analysis: because the ultrasonic cleaning machine works for a long time, inductance and transformer belong to the cooling element, it may melt and burn out due to the high temperature itself, causing short circuit.

检测和：电感、变压器的损坏，大多数情况下直观能看出烧坏的痕迹，更换新器件。

Detection and solution: the damage of inductor and transformer can be seen directly in most cases and the new device can be replaced.

7、控制板的损坏(可调超声波清洗器)

7. Damage to control panel (adjustable ultrasonic washer)

分析：超声波清洗机长时间连续工作，与元器件老化有关，还有和有时会渗入清洗液有关。

Analysis: ultrasonic cleaning machine works continuously for a long time, which is related to aging of components and components, and sometimes it will penetrate into cleaning solution.

检测和：在超声波清洗机不工作情况下，断开控制板与主板的连接。把主板通电，如超声波清洗机工作，则表示控制板损坏，需要更换。

Detection and solution: when the ultrasonic cleaning machine does not work, disconnect the control board from the main board. Power up the main board. If the ultrasonic cleaner works, it means that the control board is damaged and needs to be replaced.
