01保险丝熔断/损坏

01 fuse blown / damaged

分析:如果开机后发现电源指示灯不亮,在排除线路没电(即停电或者没有供电)的情况外,首要检查对象就是设备保险丝。

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).

检测:卸下保险,仔细看看是否有断裂,另外可以用万用表通断档进行检测,如果确认是保险丝的问题,首先要分析保险熔断的原因,然后更换零部件,开机进行测试。

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振子损坏或脱胶

02 vibrator damaged or degummed

分析:由于长时间处于启动状态,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: 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.

超声波清洗机故障解决方案(图1)

检测:用摇表测量换能器的绝缘强度,绝缘强度在200MΩ以下不能再使用,需要更换换能器,换能器的内部陶瓷也因长期使用而断裂,使其无法正常工作。

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功率管损坏

03 power tube damaged

分析:主板上的功率管由于机器持续使用时间长或不间断使用、清洗剂使用太少,可能会导致功率管出现短路情况。

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.

检测:当功率连接在主板时,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。拆卸功率管后(与主板断开连接),测量其各个管脚间应是不通的。

Detection: 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稳压管损坏

04 stabilizer pipe 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 tube is generally caused by starting the power tube after the resistance value is small or short circuit, which is rarely damaged.

检测:根据二极管特性,正向导通,反向截至。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: 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控制板的损坏(可调超声波清洗器)

05 damage of control board (adjustable ultrasonic cleaner)

分析:长时间连续工作,元器件老化有关,还有和有时会渗入清洗液有关。

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

检测:在机器不工作情况下,断开控制板与主板的连接。把主板通电,如机器工作,则表示控制板损坏,需要更换。

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电感、隔离变压器的损坏

06 damage of inductance and isolation transformer

分析:由于机器长时间工作,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 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.

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