What are the common failures of ultrasonic cleaning machines? How to solve?

Previously, we have taken a page from theultrasonic cleanerThe insurance, transducer, power tube three aspects to introduce the causes of anomalies and the corresponding measures to solve the problem, we continue to introduce other aspects of the problem, we should be how to detect and solve it?

1、Voltage regulator damage

Reason: The damage to the voltage regulator is usually caused by turning on the power after the power tube resistance is small or short-circuited, which itself is rarely damaged.

Detection and solution: According to the diode characteristics, forward conduction, reverse as of. Measured with a multimeter diode file, forward resistance value of about 70Ω, reverse ∞. If the value deviation is too large or forward resistance is also ∞, you need to replace the new voltage regulator.

2, bridge damage (diode rectifier circuit)

Cause: Same condition as voltage regulator

Detection and solution: again, based on the diode characteristics (the bridge itself is composed of diodes).

3. Damage to inductors and isolation transformers

Reason: Due to the ultrasonic cleaning machine work for a long time, inductors, transformers belong to the heat dissipation components, its own temperature may be too high and melted, burned, resulting in short-circuit and so on.

Detection and solution: inductor, transformer damage, most cases intuitively can see the burnt out traces, so that the replacement of new devices can be.

4. Damage to the control board (adjustable ultrasonic cleaner)

Reason: ultrasonic cleaners work continuously for a long time, and components aging, and sometimes penetrate the cleaning fluid is also related.

Detection and resolution: inultrasonic cleanerDisconnect the control board from the motherboard if it is not working. Energize the main board, such as ultrasonic cleaner work, it means that the control board is damaged, then need to be replaced.

The above is the voltage regulator, diode rectifier circuit, inductor, isolation transformer and control boards in several areas such as anomalies, the corresponding causes of the problem and the corresponding measures to solve the problem, through the introduction of these contents, you have a better understanding of the use of ultrasonic cleaning machine?
