如果使用不当或不注意维护保养工作的话，多槽手动超声波清洗机是很容易出现故障损坏的，常见故障有换能器损坏、功率管损坏、电源无反应、稳压管损坏、没有超声波输出等，需要排查出故障原因进行维修或更换。下面来详细讲解下。

If it is not used properly or the maintenance work is not paid attention to, the multi-slot manual ultrasonic cleaning machine is prone to failure and damage. Common failures include damage to the transducer, damage to the power tube, lack of response to the power supply, damage to the stabilizer tube, and no ultrasonic output. It is necessary to find out the cause of the failure for repair or replacement. Let's explain it in detail.

换能器损坏

The transducer is damaged

故障原因：多槽手动超声波清洗机长时间处于开机使用状态，温度逐渐上升，导致胶体融化换能器脱落或换能器陶瓷部分断裂。

Cause of failure: The multi-slot manual ultrasonic cleaning machine has been in use for a long time, and the temperature is gradually rising, which causes the gel melting transducer to fall off or the ceramic part of the transducer to break.

维修方法：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，更换新的换能器即可。

Maintenance method: use a megger to measure the insulation strength of the transducer. If the insulation strength is below 200M Ω, it can no longer be used. Replace the transducer with a new one.

功率管损坏

Power tube damaged

故障原因：多槽手动超声波清洗机长期不间断使用、清洗液体太少都会导致功率管短路。

Cause of failure: The power pipe will be short-circuited if the multi-slot manual ultrasonic cleaner is used continuously for a long time and the cleaning liquid is too little.

维修方法：功率管在主板上连接时，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，否则需要更换功率管。

Maintenance method: When the power tube is connected on the main board, use a multimeter to measure the resistance value of the pins on both sides of the power tube, which should be around 22 Ω under normal conditions, otherwise the power tube needs to be replaced.

开机后电源无反应，不显示

The power supply does not respond and does not display after startup

故障原因：接地线与火线或零线混用导致电源座内保险损坏，或者多槽手动超声波清洗机元器件老化导致短路。

Fault cause: The fuse in the power supply socket is damaged due to the mixed use of the grounding wire and the live wire or the zero wire, or the aging of the components of the multi-slot manual ultrasonic cleaner causes a short circuit.

维修方法：取出保险看有无断裂，并用万用表通断档测量是否断开，如果损坏了要更换新的保险。

Maintenance method: take out the fuse to see if it is broken, and use a multimeter to measure whether it is broken. If it is damaged, replace it with a new one.

稳压管或桥损坏

The stabilizer tube or bridge is damaged

故障原因：功率管阻值小或短路后开机会造成稳压管和二极管整流电路损坏。

Cause of failure: The power tube resistance is small or the power supply is started after a short circuit, which will cause damage to the voltage regulator and diode rectifier circuit.

维修方法：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。

Maintenance method: measure with the diode gear of a multimeter, and the forward resistance is about 70 Ω, and the reverse resistance is ∞. If the value deviation is too large or the positive resistance value is also ∞, replace the regulator with a new one.

电感、隔离变压器损坏

Damage of inductance and isolation transformer

故障原因：多槽手动超声波清洗机长时间工作导致电感、变压器等散热元件因温度过高而融化、烧毁。

Cause of failure: The multi-slot manual ultrasonic cleaning machine worked for a long time, resulting in the melting and burning of the inductor, transformer and other cooling elements due to high temperature.

维修方法：一般这两个器件损坏都是被烧坏了，可以直接看出烧坏的痕迹，无法维修，只能更换新器件。

Maintenance method: Generally, these two components are damaged by burning, and the burning trace can be seen directly. They can not be repaired, and can only be replaced with new components.

没有超声波输出

No ultrasonic output

故障原因：可能是换能器与超声波功率板的连接插头松脱、保险丝熔断、超声功率发生器故障、换能器故障。

Fault cause: The connection plug between the transducer and the ultrasonic power board is loose, the fuse is blown, the ultrasonic power generator is faulty, and the transducer is faulty.

维修方法：逐步排查问题的原因，然后进行维修或更换。

Maintenance method: gradually find out the cause of the problem, and then repair or replace it.
