超聲波清洗機故障解決方案

01保險絲熔斷/損壞

01 fuse blown / damaged

分析：如果開機后發現電源指示燈不亮，在排除線路沒電（即停電或者沒有供電）的情況外，首要檢查對象就是設備保險絲。

Analysis: if the power indicator is not on after the power on, the first object to be checked is the equipment fuse, excluding the case of no power (i.e. power failure or no power supply).

檢測：卸下保險，仔細看看是否有斷裂，另外可以用萬用表通斷檔進行檢測，如果確認是保險絲的問題，首先要分析保險熔斷的原因，然后更換零部件，開機進行測試。

Detection: remove the fuse and carefully check whether it is broken. In addition, use the multimeter to detect whether it is on or off. If it is confirmed that it is a fuse problem, first analyze the cause of fuse fusing, then replace the parts and start the machine for testing.

02振子損壞或脫膠

02 vibrator damaged or degummed

分析：由于長時間處于啟動狀態，溫度會逐漸上升，導致膠體融化，換能器脫落或換能器陶瓷部分斷裂。

Analysis: due to a long time in the start-up state, the temperature will gradually rise, resulting in colloid melting, transducer falling off or partial fracture of transducer ceramic.

檢測：用搖表測量換能器的絕緣強度，絕緣強度在200MΩ以下不能再使用，需要更換換能器，換能器的內部陶瓷也因長期使用而斷裂，使其無法正常工作。

Test: measure the insulation strength of the transducer with a megger, and the insulation strength is 200m Ω The transducer can no longer be used and needs to be replaced. The internal ceramic of the transducer is also broken due to long-term use, which makes it unable to work normally.

03功率管損壞

03 power tube damaged

分析：主板上的功率管由于機器持續使用時間長或不間斷使用、清洗劑使用太少，可能會導致功率管出現短路情況。

Analysis: the power tube on the motherboard may be short circuited due to the long continuous use of the machine or the lack of cleaning agent.

檢測：當功率連接在主板時，用萬用表測量功率管兩側管腳的阻值，正常情況下應在22Ω左右。拆卸功率管后（與主板斷開連接），測量其各個管腳間應是不通的。

Detection: when the power is connected to the motherboard, use a multimeter to measure the resistance of the pins on both sides of the power tube. Normally, it should be at 22 Ω about. After the power tube is removed (disconnected from the motherboard), the measurement should not be connected between the pins.

04穩壓管損壞

04 stabilizer pipe damaged

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

Analysis: the damage of the regulator tube is generally caused by starting the power tube after the resistance value is small or short circuit, which is rarely damaged.

檢測：根據二極管特性，正向導通，反向截至。用萬用表二極管檔測量，正向阻值70Ω左右，反向∞。如數值偏差過大或正向阻值也是∞，更換新穩壓管。

Detection: 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 with a new regulator.

05控制板的損壞(可調超聲波清洗器)

05 damage of control board (adjustable ultrasonic cleaner)

分析：長時間連續工作，元器件老化有關，還有和有時會滲入清洗液有關。

Analysis: long time continuous work, components aging, and sometimes infiltration of cleaning fluid.

檢測：在機器不工作情況下，斷開控制板與主板的連接。把主板通電，如機器工作，則表示控制板損壞，需要更換。

Detection: when the machine is not working, disconnect the control board from the main board. Power on the main board. If the machine works, it means that the control board is damaged and needs to be replaced.

06電感、隔離變壓器的損壞

06 damage of inductance and isolation transformer

分析：由于機器長時間工作，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 machine works for a long time, the inductance and transformer are heat dissipation elements, which may melt and burn due to high temperature, resulting in short circuit.

檢測：電感、變壓器的損壞，大多數情況下直觀能看出燒壞的痕跡，更換新器件。

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