超聲波在液體中傳播，使液體與清洗槽在超聲波頻率下一起振動，液體與清洗槽振動時有自己固有頻率，這種振動頻率是聲波頻率，所以人們就聽到嗡嗡聲。隨著清洗行業的不斷發展，越來越多的行業和企業運用到了超聲波清洗機。下面為大家介紹一下關于超聲波清洗機的故障以及解決方案。

Ultrasonic waves propagate in liquids, causing the liquid and cleaning tank to vibrate together at the ultrasonic frequency. When the liquid and cleaning tank vibrate, they have their own inherent frequency, which is the frequency of sound waves, so people hear buzzing sounds. With the continuous development of the cleaning industry, more and more industries and enterprises are using ultrasonic cleaning machines. Below, we will introduce the faults and solutions of ultrasonic cleaning machines.

　　1、換能器受損：

1. Damaged transducer:

　　分析：很有可能超聲波清洗機因長期處于開機使用情況，溫度會不斷上升造成膠體熔化換能器剝落或換能器陶瓷部分破裂。

Analysis: It is highly likely that the ultrasonic cleaning machine, due to long-term use on the machine, will experience continuous temperature rise, causing the colloid to melt and the transducer to peel off or the ceramic part of the transducer to rupture.

　　檢測和處理：用搖表測量換能器的絕緣強度，絕緣強度在200MΩ下列已不能使用，須更換新的換能器。

Detection and processing: Measure the insulation strength of the transducer with a shaking table. Insulation strength below 200M Ω is no longer usable and a new transducer must be replaced.

　　換能器的內部陶瓷也會因為長時間使用產生破裂，使之無法正常工作。

The internal ceramic of the transducer may also rupture due to prolonged use, making it unable to function properly.

　　2、超聲波清洗機的保險受損：

2. The insurance of the ultrasonic cleaning machine is damaged:

　　在開機后若發現無開關電源表明，無動作，首先要考慮開關電源座內保險是不是受損。

If no switch power supply is found after startup, it indicates no action. First, consider whether the fuse inside the switch power supply socket is damaged.

　　分析：很有可能是用戶接地線與火線或零線混合使用，并沒接地(本機地線是和機器外殼相連接)，也有可能是超聲波清洗機短路故障，電子元器件老化產生短路故障，造成保險受損。

Analysis: It is highly likely that the user's grounding wire is mixed with the live or neutral wire and not grounded (the grounding wire of the machine is connected to the machine casing), or it may be a short circuit fault caused by the ultrasonic cleaning machine, aging electronic components, and causing damage to the insurance.

　　檢測和處理：取出保險觀看，有沒有破裂，使用萬用表通斷檔測量是不是斷開，進行更換器件。

Detection and processing: Take out the insurance and observe if it is broken. Use a multimeter to measure whether it is disconnected and replace the components.

　　3、超聲波清洗機的功率管毀壞：

3. The power tube of the ultrasonic cleaning machine is damaged:

　　分析：主板上的功率管會由于超聲波清洗機長期無間斷使用或清洗液體太少長期使用，使功率管出現短路狀況。

Analysis: The power transistor on the motherboard may experience short circuits due to long-term uninterrupted use of the ultrasonic cleaning machine or insufficient cleaning liquid.

　　檢測和解決：當功率管在主板上連接式，用萬用表測量功率管兩側管腳的阻值，通常情況下需在22Ω以內。拿到功率管后(與主板斷開連接)，測量其各個管腳間應該是不通的。

Detection and solution: When the power transistor is connected to the motherboard, use a multimeter to measure the resistance value of the pins on both sides of the power transistor, which usually needs to be within 22 Ω. After obtaining the power transistor (disconnected from the motherboard), it should be measured that there is no connection between its various pins.
