Not all items can get clean sufficiently within a few seconds. The normal trial period can be between 2 — 10 minutes. To thoroughly and completely remove contaminants, you may need to perform an ultrasonic cleaning more than once. There are machines with lower cycle time while there are some with longer cycle time, which is suitable for people who need a machine that requires minimal supervision.
Ultrasonic Cleaning Procedure. To ensure effective cleaning, it may require that you follow some good cleaning procedures. There are some steps you can follow, but skipping s certain step or not depends on the nature of the items and how dirty or contaminated they are. Generally, ultrasonic cleaning procedures are:. The application of ultrasonic cleaners is vast. It can be used to wash and clean food items, baby toys, jewelry, surgical instruments, household tools, brittle materials, and massive engine parts.
Additionally, there exists some portable ultrasound machine that helps in washing and cleaning clothes. They can be used in place of laundry machines, as they are found effective by some users. How to Maintain and Ultrasonic Cleaners? Nowadays, most of the ultrasonic cleaning machines come with one to two years warranty, which can be voided if users do not meet certain conditions.
Here are some maintenance tips that can help you use the ultrasonic cleaner for a lifetime:. Whether you want a portable ultrasound machine or a heavy-duty industrial machine, you will find different models available on the market. The top 10 things to know about ultrasonic cleaning machine has provided you with reliable information that I believe should help you make the perfect choice when picking the best ultrasonic cleaner to meet your cleaning needs.

What is an ultrasonic cleaning machine? Top things to know about ultrasonic cleaners Closing words about ultrasonic cleaning machine What Is Ultrasonic? What Is an Ultrasonic Cleaning Machine? The Materials that make up an ultrasonic cleaning machine Aluminium or stainless steel — most of the cleaners are constructed with either of the materials, and this makes the ultrasonic cleaning machines durable and lasts a lifetime.
Tank — many of the cleaners come with a tank. Each tank varies in size and accommodates different gallons of solvent. There are some without tanks.
You will need a bowl or sink to use them. Sonic Soak is a perfect example. Piezoceramic transducers - they are always found at the bottom or side of the tank Timers and temperature controllers — this feature is not found in all models On and off switch — found in all models.
Some models offer automatic shut off Drainer — not all ultrasonic machines have this feature, but for the ones that have, the drainer helps to drain solution after cleaning Electrical energy — it powers the transducers. Most ultrasonic cleaners run at an average power of 50 watts to watts per gallon. The Cleaning Mechanism Once the power cable of an ultrasonic cleaning machine is plugged into a power source and the machine is switched on, the transducer starts changing size almost instantly.
The Frequency The frequency of ultrasonic waves is measured in thousands of cycles per second, and it is one of the determinants of the cavitation bubble size. Its Ultrasonic Power I have said it earlier that most ultrasonic cleaning machines operate at 50 watts — watts per gallon.
Differences In Ultrasonic Cleaners Ultrasonic cleaning machines come in different categories. They are: Industrial heavy duty type — This category comes with heavier compound transducers and hard-bitten generators that generate high wattage per transducers. Cleaning Solutions This is probably the factor that is mostly ignored; however, it is one of the important factors you have to consider when using an ultrasonic cleaning machine.
The Cleaning Time Typically, the cleaning time of portable ultrasound machines and other ultrasonic cleaners varies greatly.
Ultrasonic Cleaning Procedure To ensure effective cleaning, it may require that you follow some good cleaning procedures. Here is what we are offering for your dollar:. How do I get the best ultrasonic cleaning? To understand how an ultrasonic cleaner can perform cleaning or sonification, it helps to understand the principles of ultrasound and how they are applied in ultrasonic cleaning. Ultrasound is sound transmitted at frequencies beyond the range of human hearing.
Ultrasonic energy generated by piezoelectric transducer at a rate of 40, times per second creates cavitation, the mechanism for ultrasonic cleaning. Cavitation consists of the formation and collapse of countless tiny cavities, or vacuum bubbles, in the liquid. The energy produces alternating high and low pressure waves within the liquid in the tank. The liquid is compressed during the high-pressure phase of the wave cycle, then pulled apart during the low-pressure phase.
As the pressure in the liquid is reduced during the low-pressure phase, cavities grow from microscopic nuclei to a maximum critical diameter. During the subsequent high-pressure phase they are compressed and implode. The energy is powerful but safe for parts because it is localized at microscopic scale.
Factors affecting the strength of cavitation are:. Ultrasonic Cleaning Best Practices. For example, a microprocessor-based digital thermostatic control allows a constant display of the solution temperature for close monitoring and control. Heat also increases the chemical activity of cleaning solutions. Solution temperature generally should be kept between deg. If the temperature and time can be controlled, then repeatable cleaning consistency can be achieved.
Reduced surface tension will increase cavitation strength. Medium vapor pressure is most conducive to ultrasound activity. Low vapor pressure produces cavitation bubbles that implode with relatively greater force, but results in fewer bubbles and a higher cavitation threshold.
Low viscosity promotes cavitation. It can cause the unit to fail because the parts will reflect the ultrasonic energy back into the transducer s. Always allow at least one inch between the tank bottom and the beaker or receptacle for adequate cavitation.
It is neither safe nor environmentally responsible. Solvents vaporize quickly. Vapors of flammable solutions can collect under the unit, where ignition is possible from electrical components. In the liquid versus cavitational activity relationship, it does not follow that less solution will intensify the activity. Units operate at optimum efficiency when filled to within one inch of the top.
This need not be repeated with subsequent use, as degassing is required only after the bath is freshly filled. This also permits free access of the sound waves to the parts. Solutions, as with most chemicals, become spent over time.
Solutions can become contaminated with suspended soil particles, which can settle to the tank bottom inhibiting ultrasonic transmission. What is the difference between direct and indirect cleaning? How long will it take to clean my parts? This is kind of like asking "How far is up? Cleaning time will depend on what you're cleaning, how many of what you're cleaning, and how dirty the thing your cleaning is.
A gummed up carburetor will take longer to clean than say, a dusty piece of jewelry. Temperature and cleaning solution also play a part in cleaning time. In general, a tank of hot, fresh solution will clean better and faster than a tank of just cold water.
Will an ultrasonic cleaner damage my parts? The thing to keep in mind with ultrasonics is that all they do is scrub indiscriminately. An ultrasonic bath doesn't know the difference between a flimsy coating on a lens or a layer of soil, and will scour both off.
However ultrasonics have been proven safe for most parts, and the biggest thing to consider to ensure the safety of your parts is choosing the correct cleaning solution. Do I have to fill my tank to the "Fill" line? Your ultrasonic cleaner's manufacturer designed the unit to work best when filled to that line. If under filled, the characteristics of the environment change, which could result in improper ultrasonic transmission, which in turn could result in poor cleaning performance or damage to the unit.
Units with a heater are especially at risk of damage due to underfilling. If the heating element isn't covered by the water line, warping of the tank itself could occur. The answer to this question depends on what you're trying to do.
In general, if are cleaning heavy or petroleum based soils from parts, hot water and thus a heated tank is recommended. Do you need them? Yes and No. The main function of insertable trays or baskets is to hold the part being cleaned off the bottom of the tank. For cavitation to occur, your ultrasonic cleaner needs about an inch between the transducer and the object being cleaned.
Baskets also assist in removing parts for the unit, and in some cases drainage. What's the best cleaning temperature? Generally ultrasonics work best between and degrees fahrenheit. It's important however to make sure these temperatures are safe for your parts before cleaning. How do I drain my ultrasonic cleaner?
Smaller units will not have a drain. Pour out your old solution, then rinse out your tank before adding new solution. Be sure to properly dispose of your cleaning solution.
Larger units will be equipped with a drain tube on the side or rear of the cleaner. Here's how to install and use it:. Hand tighten the drain valve onto the drain pipe over the white teflon sealing tape. Finish tightening the valve in place using an adjustable or a 21mm wrench.
Tighten the valve no more than one full turn when using the wrench until the handle is on top. Always use teflon sealing tape or a sealing paste designed for use with stainless steel if retightening or refitting of the drain valve is required.
Hand tighten the hose adaptor into the end of the drain valve. Slide the drain tube over the barbed hose adaptor end. Close the drain valve by turning the handle perpendicular to the valve body and the unit is ready to fill with solution. To open the valve and drain the tank, turn the handle so that it is in line with the valve body. What can I clean in my ultrasonic cleane r? Ultrasonics will clean just about any organic soil from any hard surface. If you can scrub it off with a brush, you can most likely get it off with ultrasonics.
Some common uses for ultrasonic cleaners include:. Consistent repeatable results every time. Our ultrasonic baths thoroughly remove blood, protein, reagents, and other contaminants. Powerful ultrasonics can support your industrial workflow.

Dec 13, 55 2 8 Cleveland, Ohio Country Region. I plugged it in and it hums and warms up the water.
There was no manual, so I am wondering a few things: 1. How long I should leave parts in there to clean? I did buy some Zenith, but it came without suggested timeframes. Can parts be left in the ultrasound too long? Do I need to worry if it is working properly - right frequency? Is there any way to tell or test it? Feb 19, 10 18 Country Region. You might think that "longer is better", but there are practical limits. Another thing to remember is that the cleaning solutions very often contain additives to brighten the wheels, plates and bridges.
If these parts are left in too long, the cleaning solution may very well go from brightening these parts to attacking these parts! So you CAN have 'too much of a good thing'.
Your best bet is to limit the cleaning time to 3 to 4 minutes, and the rinse time to 2 to 3 minutes. When you greatly exceed these time intervals, you begin to reach the point of diminishing returns. If the parts are extremely dirty, it is better to clean them more than once, using fresh solutions each time.
