1、換能器損壞：

1. Transducer damage:

分析：可能超聲波清洗機(jī)因長時間處于開機(jī)使用狀態(tài)，溫度會逐漸上升導(dǎo)致膠體融化換能器脫落或換能器陶瓷部分?jǐn)嗔选?/p>

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.

檢測和解決：用搖表測量換能器的絕緣強(qiáng)度，絕緣強(qiáng)度在200MΩ以下已無法使用，須換新的換能器。

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.

換能器的內(nèi)部陶瓷也會由于長期使用出現(xiàn)斷裂，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、超聲波清洗器的保險損壞：

2. Insurance damage to ultrasonic washer:

在開機(jī)后如發(fā)現(xiàn)無電源顯示，無動作，首先要看電源座內(nèi)保險是否損壞。

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：有可能是用戶接地線與火線或零線混用，并沒有接地(本機(jī)地線是與機(jī)器外殼相連接)，還有可能是超聲波清洗機(jī)短路，元器件老化出現(xiàn)短路現(xiàn)象，導(dǎo)致保險損壞。

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.

檢測和解決：拿出保險觀看，有無斷裂，用萬用表通斷檔測量是否斷開，更換新器件。

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、超聲波清洗器的功率管損壞：

3. The power tube of the ultrasonic cleaner is damaged

分析：主板上的功率管會因?yàn)槌暡ㄇ逑礄C(jī)長時間不間斷使用或清洗液體太少長時間使用，使功率管出現(xiàn)短路情況。

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.

檢測和解決：當(dāng)功率管在主板上連接式，用萬用表測量功率管兩側(cè)管腳的阻值，正常情況下應(yīng)在22Ω左右。拿下功率管后(與主板斷開連接)，測量其各個管腳間應(yīng)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、穩(wěn)壓管損壞

4. The stabilizer tube is damaged

分析：穩(wěn)壓管的損壞一般是在功率管阻值小或短路后，開機(jī)造成的，其本身是極少損壞的。

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.

檢測和解決：根據(jù)二極管特性，正向?qū)ǎ聪蚪刂痢Ｓ萌f用表二極管檔測量，正向阻值70Ω左右，反向∞。如數(shù)值偏差過大或正向阻值也是∞，更換新穩(wěn)壓管。

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、橋的損壞(二極管整流電路)

5. Bridge damage (diode rectifier circuit)

分析：同穩(wěn)壓管狀況

Analysis: same as the condition of the regulator

檢測和解決：同樣根據(jù)二極管特性(橋本身就是由二極管組成)

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

6、電感、隔離變壓器的損壞

6. Damage of inductance and isolation transformer

分析：由于超聲波清洗機(jī)長時間工作，電感，變壓器屬于散熱元件，其本身有可能會因溫度過高而融化，燒毀，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.

檢測和解決：電感、變壓器的損壞，大多數(shù)情況下直觀能看出燒壞的痕跡，更換新器件。

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

7、控制板的損壞(可調(diào)超聲波清洗器)

7. Damage to control panel (adjustable ultrasonic washer)

分析：超聲波清洗機(jī)長時間連續(xù)工作，與元器件老化有關(guān)，還有和有時會滲入清洗液有關(guān)。

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.

檢測和解決：在超聲波清洗機(jī)不工作情況下，斷開控制板與主板的連接。把主板通電，如超聲波清洗機(jī)工作，則表示控制板損壞，需要更換。

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.
