The material forming the ultrasonic cleaning machine
Aluminum or stainless steel -- both are used in most cleaners, making them durable and long-lasting.
Water tanks-many detergents come with water tanks. Each can has a different size and can hold different gallons of solvent. Some don't have tanks. You will need a bowl or sink to use them. Sonic Soak is a good example.
Piezoelectric ceramic sensors-they are always at the bottom or side of the tank
Timers and temperature controllers -- not all models have this capability
On and off switches -- available in all models. Some models provide automatic shutdown
Drain-not all ultrasonic machines have this feature, but for machines with this feature, the drain helps to drain the solution after cleaning
Electricity -- it powers the transducer. The average power of most ultrasonic cleaning machines is 50 to 100 watts per gallon.
Shelves or baskets-help prevent scratches or etches when cleaning items
Operation mode-some ultrasonic cleaning machines have a scanning mode that produces slight fluctuations in frequency, while a pulse mode increases ultrasonic power.
Please note that the size of the water tank and basket should be taken into account when purchasing ultrasonic machines. Choose the size of the object you want to clean and clean.                                                     
                                                                                                        
Clean mechanism
After the power cord of the ultrasonic cleaner is plugged in and the machine is turned on, the transducer begins to change size almost immediately. It then converts electrical energy into ultrasonic energy.
Due to excitation, the transducer increases in size, generating high-frequency compressed sound waves and causing the rapid formation and rupture of cavitation bubbles.
As the compression wave continues, the cavitation bubbles grow larger, and when they reach a certain size and can no longer maintain their shape, the bubbles stir in the liquid to separate it.
These bubbles can affect objects in the tank, causing dust, dirt, bacteria, oil, pigments and other contaminants that may stick to the object to fall off. The same thing happens when you put a portable ultrasound machine in a sink or bowl of water.
Frequency
The frequency of ultrasound, measured in thonds of cycles per second, is one of the determinants of cavitation bubble size. The high frequency produces small bubbles that provide a gentle cleaning effect.
Low frequencies, on the other hand, produce relatively large bubbles that collapse inward in a very sudden and violent manner. You can hardly distinguish the size of the bubbles visually.
This means that if you want to remove dirt and other contaminants from durable items, you need a low-frequency ultrasonic cleaner. However, if you want to clean and clean delicate and soft items such as jewelry and food, you need to use more frequent ultrasonic cleaners.
They are also the perfect cleanser for items in narrow areas. But a frequency of 40 kHz is usually appropriate for most applications. Whether you want to grow or need a portable ultrasound machine, if you want to clean a variety of objects, please consider using dual-frequency ultrasonic cleaner.
It's ultrasonic power
As I said before, most ultrasonic cleaners run at 50 Watts-100 Watts per gallon. Increasing the power of the cleaner will result in increasing the number of bubbles produced during cavitation.
With the increase of power, the cleaning action of the machine becomes faster. However, it has a limitation. Once you exceed the power limit, you risk damaging the object you are cleaning and wasting energy.
It's nice to know that power is described in different ways when it comes to ultrasonic cleaning. And ultrasonic power, which has been discussed above.
In addition, we have the total power and peak power to drive the whole unit, that is, the ultrasonic power generated at the peak of the sound wave.
The difference between ultrasonic cleaning machine
There are different types of ultrasonic cleaning machines. They are:
Industrial heavy duty type-this type is equipped with heavier composite transducers and hard tooth generators, each of which can produce high power. Their tanks are made of heavy-duty welded stainless steel, and the generators are separated from the tanks. These types of ultrasonic cleaning machine is basically used for production cleaning, the effect is very good.
Small lab-sized desktop cleaners-they also have heavy-duty sensors, but not like heavy-duty industrial ones. The generator is better and more efficient at cleaning lab glass and small objects. In addition, the generator and the fuel tank are integrated in the same housing. Even if they can be used for a long time, they should not be used for production cleaning because they are not suitable for 24/7 operation.
Small toy-type systems-they can be called portable ultrasound machines. Sonic Soak is a good example of this type of ultrasonic cleaning machine. They are lightweight cleaners with simple generators and small transducers. This category is used for cleaning and cleaning jewelry, baby toys, clothing and food, such as vegetables, fruits, meat, etc.
Cleaning solutions
This is probably the most overlooked factor; however, it is one of the most important factors you must consider when using an ultrasonic cleaner.
Consider the properties of the fluid you want to use. Don't just buy cleaning fluid on the inside of the ultrasonic cleaning machine, do not look carefully. In general, most detergents are water-based. But you can use other cleaning solutions to speed up the cleaning process.
Make sure you choose a solution that does not have too high or too low surface tension. Make sure the solution can remove dirt and keep it in the solution. Also, make sure the liquid is safe to use. It should not be too alkaline or too acidic, but rather something fairly close to neutral.
In addition, any cleaning solution you use should be fully mixed with water and degassed quickly. In portable ultrasound machines and other larger machines, degassing takes three to four seconds.
If you intend to use an ultrasonic cleaner to clean food, it is recommended that you use water. However, if it is used to clean iron or other materials that may rust, make sure the cleaning fluid has an antirust agent to prevent the object from rusting after cleaning.
Alternatively, you can save yourself the stress of finding the perfect ultrasonic cleaning solution by asking the manufacturer of your cleaning machine.
Cleaning time
In general, the cleaning time of portable ultrasonic machines and other ultrasonic cleaners varies greatly. It depends on how dirty the object or part is. Not everything can be thoroughly cleaned in seconds.
The normal trial period can be between 2 and 10 minutes. To completely remove contaminants, you may need to perform multiple ultrasonic cleaning.
Some machines have a shorter cycle time, while others have a longer cycle time, which is suitable for people who need machines that require minimal supervision.
Ultrasonic cleaning procedure
To ensure effective cleaning, you may need to follow some good cleaning procedures.
You can follow some steps, but whether you skip some depends on the nature of the items and how dirty or contaminated they are. In general, ultrasonic cleaning procedures are:
Pre-rinse-perform this step if there is a large amount of contamination that needs to be removed. Warm water is used to remove large amounts of debris and contaminants from articles.
Put an object in an ultrasound canister -- a step no object can skip. After pre-rinsing items, place them in a water tank. This should be done methodically. You can use a basket instead of putting items directly into a water tank. For portable ultrasound machines such as Sonic Soak, which do not have a tank, you can put items in the sink and clean them.
After ultrasonic cleaning-you can skip this step if you use the right fluid.
All items that can be cleaned by an ultrasonic cleaning machine
Ultrasonic cleaning machine is widely used. It can be used for cleaning and cleaning food, baby toys, jewelry, surgical instruments, household tools, brittle materials and large engine parts. In addition, there are portable ultrasound machines that can help wash and clean clothes. They can be used in place of washing machines because some users find them very effective.
How to maintain the ultrasonic cleaning machine?
Now most of the ultrasonic cleaning machines have a warranty period of one to two years, if the user does not meet certain conditions, can be canceled. Here are some maintenance tips that can help you use an ultrasonic cleaner throughout your life:
Do not operate if the solution is too low. It will damage the transducer
Do not tilt the solution to prevent it from flowing into the equipment
Don't let the instrument touch the bottom of the water tank, or it will scratch or corrode the machine
Do not use highly alkaline or acidic solutions
Make sure that the ultrasonic washer is not placed on wet surfaces or on wet towels or clothes.
Ensuring proper maintenance of your cleaning machine can help you achieve optimal performance.
