What are the solutions to the common faults of ultrasonic cleaners?

1. Check the switch panel.

Many users will face the problem of control panel failure in the process of using ultrasonic cleaners. There is no need to worry about this, as it may be caused by long-term operation, aging of internal components, or infiltration of cleaning fluid. In the face of such a situation, you can disconnect the power supply first, and then disconnect the motherboard from the control board, power on the motherboard, and replace the control board in time if there is no abnormality.

2. Check the insurance status.

A small number of ultrasonic cleaners have neither power display nor any action after powering on. In the face of such a situation, the customer can first observe the overall instrument, if there is a peculiar smell in the machine, it may be caused by a short circuit caused by damage to the components in the instrument, and most of this kind of situation can be directly released, and the component can be replaced in time. Of course, it is also possible that the fuse burns out due to the instrument not being grounded, and the user can know by looking at the fuse that it should be replaced immediately if it breaks.

3. Call the original manufacturer in time.

After testing the ultrasonic cleaner by the above two methods, there is no need to worry if there is still no effect. Users only need to go to the electrogen manufacturer, ask for more professional advice, and then carefully test according to their suggestions, I believe that they will be able to overcome many difficulties. Under normal circumstances, the original manufacturer will have a timely emergency plan for this situation, so users do not have to worry about the problem that cannot be solved by the original manufacturer.

1. The power supply of the ultrasonic cleaner and the power supply of the electric heater must have a good grounding device.

2. It is strictly forbidden to start the ultrasonic cleaner when there is no water or solvent in the tank, which will cause air vibration and cause scrap or damage to the vibrating head.

3. It is strictly forbidden to turn on the heating switch when there is no liquid in the cleaning equipment with heating system.

4. It is forbidden to hit the bottom of the cleaning cylinder with heavy objects (iron parts) to avoid damage to the energy converter chip.

5. The bottom of the cleaning cylinder should be washed regularly, and there should be no excessive debris or dirt.

6. Do not put your fingers into the cleaning tank during the operation of the cleaning machine, otherwise you will feel stinging or uncomfortable.

7. Each time the new liquid is changed, the parts can be washed only after the ultrasonic start.

8. Use water or aqueous solution as the cleaning agent, try not to use alcohol, gasoline or any combustible gas as the cleaning agent to add to the cleaning machine, which is easy to cause fire, etc.

9. The best way to make the ultrasonic cleaning effect is the best way to make the ultrasonic cleaning tank, the temperature of the ultrasonic cleaning tank is best to be 60 70, and the cleaning agent is correctly selected according to different cleaning objects. Cleaning agents are generally divided into water-based (alkaline) cleaning agents, organic solvent cleaning agents and chemical reaction cleaning agents. Water-based cleaners are usually the most commonly used, and different cleaning times are selected depending on the degree of contamination and the nature of the dirt to be cleaned.

The transducer inside the ultrasonic cleaner generally rarely fails, and if there is a problem, it is generally caused by the following reasons.

The ultrasonic transducer is damp.

Generally, a megohmmeter is used to check the plug connected to the transducer, and the insulation resistance value between the positive and negative poles of the transducer can be judged. Generally, the insulation resistance is greater than 30 megaohms. If this insulation resistance value is not reached, it is likely that the transducer is damp.

The maintenance method is to put the whole transducer (excluding the spray shell) into the oven to set about 100, dry for three hours or use a hair dryer to remove moisture until the resistance value is normal.

The transducer oscillator ignited, and the ceramic material shattered.

Repairs can be checked with a combination of visual and megohmmeter. Generally, as an emergency treatment measure, the individual damaged transducers can be disconnected, which will not affect the normal use of other transducers.

Transducer degumming.

We know that most manufacturers use adhesive to fix the transducer, but after long-term use of the ultrasonic cleaner, there will be degumming due to vibration. There are also manufacturers using cementation and screw fastening, generally will not appear degumming, due to the effect of the screw, the oscillator will not fall from the vibration surface after degumming, the general judgment method is to gently shake the tail of the oscillator by hand, carefully observe the glue situation of the vibration surface to make a judgment.

Generally, the power output of the ultrasonic power supply is normal after the oscillator is degummed, but because the oscillator is not well connected with the vibrating surface, the vibration effect of the vibrating surface is not good, and the oscillator is likely to burn out because the energy cannot be released after a long time. The degumming of the oscillator is more troublesome for the user to maintain, and it can only be sent back to the manufacturer for maintenance under normal circumstances. The most effective way to avoid the degumming of the oscillator is to pay attention not to impact the vibrating surface during daily use.

Vibrating surface perforation.

Generally, the ultrasonic transducer may be perforated after several years of full load use, which is caused by the long-term high-frequency vibration fatigue of the stainless steel plate of the vibrating surface.

1. Common faults of ultrasonic cleaners.

1. Insurance damage. If you find that there is no power display and no action after starting, you should first see whether the insurance in the power socket is damaged. It may be that the user is connected to the ground wire of the spike wheel and the live wire or the neutral wire, and there is no grounding (the ground wire of the machine is connected to the shell of the machine), and it may be that the machine is short-circuited, and the components are aging and the short-circuit phenomenon is present, resulting in damage to the insurance.

2. The transducer is damaged. It may be that the temperature will gradually rise due to the long-term use of the machine, which may cause the colloid to melt and the transducer to fall off or the transducer ceramic to break partially.

3. The power tube is damaged. The power tube on the motherboard will be short-circuited due to the long-term uninterrupted use of the machine or too little cleaning liquid.

4. The stabilizer tube is damaged. The damage of the stabilizer tube is generally caused by the start-up after the resistance of the power tube is small or short-circuited, and it is rarely damaged.

5. Damage to the control board (adjustable ultrasonic cleaner). Long-term continuous work is related to the aging of components, and sometimes it is related to the penetration of cleaning liquid.

6. Damage to inductance and isolation transformer. Due to the long-term operation of the machine, the inductance and transformer belong to the heat dissipation components, which may melt and burn out due to excessive temperature, resulting in a short circuit.

2. Daily maintenance of ultrasonic cleaner.

1. Insurance damage. Take out the insurance**, whether there is a break, use the multimeter to measure whether it is disconnected, and replace the new device.

2. The transducer is damaged. Use a shake meter to measure the dielectric strength of the transducer, the dielectric strength is less than 200m can no longer be used, and a new transducer must be replaced. The internal ceramics of the transducer can also break due to long-term use, making it unable to function properly.

3. The power tube is damaged. When the power tube is connected on the motherboard, use a multimeter to measure the resistance value of the pins on both sides of the power tube, which should be about 22 under normal circumstances. After removing the power tube (disconnected from the motherboard), the measurement pins should be impassable.

4. The stabilizer tube is damaged. Depending on the diode characteristics, it is forward and reverse is turned off. Measured with a multimeter diode file, the forward resistance is about 70, and the reverse is reversed. If the value deviation is too large or the forward resistance value is also the same, replace the new regulator tube.

5. Damage to the control board (adjustable ultrasonic cleaner). When the machine is not working, disconnect the control board from the motherboard. Powering on the motherboard, if the machine is working, it means that the control board is damaged and needs to be replaced.

6. Damage to inductance and isolation transformer. In most cases, the damage of inductors and transformers can directly see the traces of burnout, and replace the new devices.

Jiangsu Jiujiu Jiayi Ultrasonic Technology **** answers for you: ultrasonic cleaning machines are used in cleaning work in all walks of life During use, ultrasonic cleaning machines are affected by a variety of factors, and these factors can be controlled well, so that the cleaning machine can play its role to the maximum.

1. The influence of the physical and chemical properties of the cleaning liquid on the cleaning effect.

When choosing a cleaning agent, you should choose a cleaning agent with good chemical action and surface tension, and you should not choose a corrosive or volatile cleaning agent.

2. The influence of the temperature of the cleaning solution on the working effect of the cleaning agent.

If the temperature of the cleaning solution is too low or too high, it is abnormal, which will affect the performance of the ultrasonic cleaning machine. In addition, the flow rate of the cleaning liquid should not be too fast, the detergent needs to flow and renew constantly, but the flow rate should be well controlled.

3. The gas content in the detergent will also affect the working effect of the ultrasonic cleaner.

If the cleaning agent contains residual gases, the sound transmission loss will increase, the intensity of the shock wave will be reduced, and the working effect of the machine will be adversely affected.

The working effect of the ultrasonic cleaner is mainly affected by the above factors, so you may wish to refer to it when using it, so as to make the use effect better.
