What is an ultrasonic cleaning machine and how does it work?
Before deciding what kind of ultrasonic cleaning machine to buy, get to know what an ultrasonic cleaning machine is and how it works.
Ultrasonic cleaning machine is a tool for cleaning objects by ultrasonic wave. It is used to clean all kinds of things, from exquisite jewelry to dirty carburetor, from glasses to industrial products.
The ultrasonic cleaning process is realized by acoustic cavitation. This is a process of generating tiny implosion bubbles on a microscopic scale. When these bubbles implode, they have the ability to produce a cleaning effect.
Ultrasonic cleaning machine is always used in combination with liquid cleaning solution. This liquid transmits ultrasonic waves to the surface of the object to be cleaned and also helps to remove pollutants.
What are the benefits of ultrasonic cleaning machine?
Let's take a look at some benefits of ultrasonic cleaning compared with other cleaning methods.
It can remove almost all pollutants. Using the correct cleaning solution, the ultrasonic cleaning machine can remove almost all pollutants. Can be used to remove oil stains, dirt, fingerprint stains, old paint, burnt carbon and so on. This operation can be carried out on most objects made of metal, plastic, glass, ceramics, etc.
However, with a few exceptions, it is important to use the correct cleaning solution to clean items. For example, aluminum will corrode if it is washed with the wrong solution.
Clean the hardest parts. Ultrasonic waves in the cleaning solution can reach places that cannot be reached by hands.
It takes very little time and energy. After entering the cleaning process, there is no need to do too much. In addition to inserting and taking out objects in the basket of the ultrasonic cleaner, you can finish cleaning by pressing a few buttons, and you can spend your time doing whatever you want.
Safe for the environment. Unlike other cleaning methods, there is no need to use irritating solvents. These are harmful not only to the environment, but also to the skin and lungs. In addition, there is no risk of being cut by sharp objects, such as manual cleaning of drill bits, scalpels or other sharp tools.
With these benefits, a good ultrasonic cleaning machine can easily recover the cost. You can make time without manual cleaning or spending money on expensive solvents. In addition, you don't have to go out to clean things professionally, saving time and money!

What is ultrasonic cleaning?
The principle of ultrasonic cleaning equipment of Jiangsu Jiujiu Jiayi Ultrasonic Technology Co., Ltd. is that the high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated into the medium? So as to achieve the purpose of cleaning the surface of parts.
Usage: It is suitable for cleaning stamping oil and mechanical oil produced in the processing of hardware, plastics and other workpieces, and can be diluted in different proportions and cleaned in different ways according to different conditions to meet the ideal cleaning requirements of workpieces.
What are the cleaning methods of ultrasonic cleaning machine?
Ultrasonic cleaning machines are generally used in large manufacturing plants to clean the dirt of those equipment. Then how to clean the ultrasonic cleaning machine when it is dirty? The following is the cleaning of the ultrasonic cleaning machine I arranged for you. I hope it will help you.
Cleaning of ultrasonic cleaning machine
1. According to the installation instructions, connect the temperature sensor signal line, ultrasonic drive line, heater control line and other lines between the electric control cabinet and the main engine of the ultrasonic cleaning machine, connect the 380VAC power supply, and install the water inlet pipe, drain pipe and overflow drain pipe of the cleaning machine.
2. Ultrasonic cleaning of pool water
Add a proper amount of clean water to the cleaning pool, and the liquid level shall be subject to immersion of the parts to be cleaned, generally not exceeding three quarters of the cleaning pool.
3. Ultrasonic cleaning and heating
Start the electric heating switch and point the white scale line on the water temperature adjustment knob to the appropriate temperature. When the cleaning machine is used, the maximum temperature of the cleaning agent shall not exceed 70℃.
4. Add cleaning agent to the ultrasonic cleaning machine.
When the water temperature rises to about 40℃, add UC-O3 cleaning agent into the cleaning pool, and slowly stir the clean water to fully dissolve it.
5. Pretreatment of ultrasonic cleaning machine
Before cleaning, it is advisable to simply clean the dirt on the surface of the parts with a bamboo knife to prolong the service life of the cleaning solution.
Ultrasonic wave can be used for precision cleaning, but its ability to treat sludge is weak, so yellow mud or sludge should be removed as much as possible in pretreatment.
Maintenance of ultrasonic cleaning machine
1) Frequently asked questions of ultrasonic transducer:
1 If the ultrasonic vibrator is damp, you can check the plug connected to the transducer with an megger, and you can judge the basic situation by checking the insulation resistance. Generally, the insulation resistance is required to be greater than 5 megohms. If the insulation resistance does not reach this value, it is generally that the sensor is wet. You can put the whole transducer in the oven, set it at 100℃ and dry it for 3 hours, or use a hair dryer to remove moisture until the resistance is normal.
2. When the transducer vibrator is ignited and the ceramic material is broken, it can be checked by naked eyes and megger. Generally, as an emergency treatment measure, individual damaged vibrators can be disconnected without affecting the normal use of other vibrators.
3. Degumming of vibrator, our transducer adopts the double guarantee process of cementation and screw fastening, which will not happen under normal circumstances.
4 stainless steel vibration surface perforation. In general, the vibration surface may be perforated after the transducer is used at full load for 10 years.
2) Frequently asked questions about transducer of ultrasonic cleaning machine:
(1) The ultrasonic transducer is damp. Generally, the insulation resistance between the positive and negative electrodes of the transducer can be judged by checking the plug connected to the transducer with a megger. Generally speaking, the insulation resistance is required to be greater than 30 megohms. If the insulation resistance value cannot be reached, it may be that the sensor is wet. The maintenance method is to put the whole transducer into an oven, set the temperature at about 100℃, and dry it for three hours or use a hair dryer to remove moisture until the resistance is normal. When the transducer vibrator is ignited, the ceramic material is broken. Maintenance can be checked by naked eye and megger. In general, as an emergency measure, individual damaged sensors can be disconnected without affecting the normal use of other sensors.
⑵ transducer degumming. We know that most manufacturers use glue to fix transducers, but after long-term use, ultrasonic cleaning machines will be degummed due to vibration. There are also manufacturers who use screws to bond and fasten, which generally does not cause degumming. Because of the screw, the vibrator will not fall off the vibration surface after degumming. The general judgment method is to gently shake the tail of the vibrator by hand, carefully observe the glue on the vibration surface and make a judgment.
⑶ In general, after the vibrator is degummed, the output power of the ultrasonic power supply is normal. However, due to the poor connection between vibrator and vibrating surface, the vibration effect of vibrating surface is not good. After a long time, the vibrator is likely to burn out because the energy cannot be released. The vibrator is degummed, which is troublesome for users to maintain. Generally, it can only be sent back to the manufacturer for repair. The most effective way to prevent the vibrator from degumming is to be careful not to touch the vibration surface during normal use.
(4) Perforation of vibration surface. Generally, after several years of full-load use, the vibration surface of ultrasonic transducer may be perforated, which is caused by long-term high-frequency vibration fatigue of stainless steel plate on the vibration surface. The perforation of vibration surface indicates that the transducer has reached its service life and can only be replaced during maintenance.
3) Frequently asked questions of ultrasonic cleaner generator:
(1) Turn on the power switch of the ultrasonic cleaning machine, and the indicator light will not light up. In this case, it is necessary to check whether the power switch is in good condition and whether the leakage switch is closed. If the switch is in good condition, check whether the fuse is overloaded and blown, which can basically be solved.
⑵ After the ultrasonic cleaning machine turns on the power switch, the indicator light is on, but there is no ultrasonic output. This situation is more complicated. During maintenance, first check whether the connecting plug between the transducer and the ultrasonic power board is loose, and then check whether the fuse is blown. If everything is all right, it may be an internal fault of the ultrasonic generator. Open the power cord with a multimeter, and whether all the live wires are connected properly. After troubleshooting the generator, check whether the ultrasonic transducer is burnt out and needs to be replaced.
(3) The DC fuse of the ultrasonic cleaning machine is blown. It may be that the rectifier bridge stack or power tube is burnt out, or the transducer is aging and the current is unstable, which leads to the generator failure. Pay more attention to maintenance.
Use of ultrasonic cleaning machine
(1) The power supply of ultrasonic cleaning machine and heater must have good grounding devices.
⑵ It is forbidden to start the ultrasonic cleaning machine without cleaning liquid, that is, it is not allowed to turn on the ultrasonic switch without adding a certain amount of cleaning liquid to the cleaning cylinder.
(3) When there is no liquid in the cleaning equipment with heating equipment, it is forbidden to turn on the heating switch.
(4) It is forbidden to hit the bottom of the cleaning cylinder with heavy objects to avoid damaging the transducer chip.
5] The power supply of the ultrasonic generator should be a single power supply of 220V/50Hz, and equipped with a voltage regulator of more than 2000W W. ..
[6] Clean the bottom of the cylinder regularly without excessive sundries or dirt.
What is the principle of ultrasonic cleaning?
1, the principle of ultrasonic cleaning machine is mainly to convert the acoustic energy of power ultrasonic frequency source into mechanical vibration through the transducer, and radiate ultrasonic waves to the cleaning liquid in the tank through cleaning the tank wall. Due to the radiation of ultrasonic waves, the microbubbles in the liquid in the tank can keep vibrating under the action of sound waves. Destroy the adsorption of dirt and the surface of cleaning parts, cause the dirt layer to fall off due to fatigue damage, and the vibration of bubbles scrubs the solid surface.
2. Using ultrasonic cleaning, there are generally two kinds of cleaning agents: chemical cleaning agents and water-based cleaning agents. Cleaning medium is chemical action, while ultrasonic cleaning is physical action. These two actions are combined to completely and thoroughly clean the object.
