The cleaning principle of ultrasonic cleaning machine

Date: 2022-09-20Number: 245

Ultrasonic cleaning has long been the preferred method of professional cleaning. Ultrasonic cleaning has existed for 60 years. These state-of-the-art and innovative cleaning technologies make it easy to remove stains, contaminants, debris, and dirt from even the most difficult-to-clean materials.

Since World War II, experts have seemed obsessed with the concept of ultrasound. This inaudible frequency of 20,000 to 100,000 cycles per second has long been a defining feature of everything from defense and military applications to medical technology.

The cleaning industry has not been shut out. Ultrasound now dominates cleaning. Using the principle of ultrasound, we can clean jewelry and medical equipment and other objects.

However, a lot of people do not quite grasp the ultrasonic cleaning machine cleaning principle.

They are made of a variety of materials

Although most people know about ordinary washing machines, many people don't know what an ultrasonic washing machine consists of. Ultrasonic cleaning machine consists of three basic components: cleaning tank, generator and transducer.

Cleaning tank: ultrasonic cleaning machine has a number of cleaning tank size to choose from, the size of the selected equipment depends on the size and number of items to be cleaned.

Generator: a generator is mechanical energy that converts electrical energy from its source into the form of sound waves. This sound wave consists of millions of tiny bubbles. Each bubble is filled with a vacuum effect called implosion. When the bubble collapses on the cleaned object, it implodes, removing debris from the object. This process is called cavitation.

Transducer: Transducer is the most important part of ultrasonic cleaning machine. The use of electrical energy generated by the generator, is the human ear can not hear the sound frequency, ultrasonic frequency is generally about 40kHz.

The transducer has two core parts: the frequency plate and the transducer itself. For most cleaners, piezoelectric crystals are used as active components. They are usually at the bottom.

Other features, such as timers, temperature control switches, and rack baskets, are available for many models. So before buying ultrasonic cleaning machine, to understand its role and specifications model. Ensure that the capacity of the selected washer is sufficient to meet the requirements.

How the cleaning took place

Connect the device to a power supply, turn on the power switch, and the generator and sensor start working immediately. As the generator gradually converts direct power into the electrical energy of the transducer, the transducer gradually vibrates and pulses. Gradually convert electrical energy into ultrasonic energy.

The transducer also generates high-frequency compressed sound waves due to its rapid movement. This type of motion eventually leads to the formation of cavitation bubbles, which, when this process occurs, pass through the cleaning fluid and are quickly cleaned.

The tiny bubbles can attack parts and remove contaminants. The strength of the process ensures that everything will look as good as new.

Frequency of ultrasonic cleaning

Ultrasound is about the frequency of sound. Ultrasonic frequency is measured in thousands of cycles per second. In general, ultrasound ranges from 20 khz to 100 khz. Most ultrasonic cleaning occurs at 40 to 60 khz.

The frequency level determines the type of cleaning that is created. At high frequencies, small bubbles can also form, providing a gentler, more detailed cleaning effect. Lower frequency should be used if large amounts of dirt and contaminants are to be cleaned. The lower the frequency, the larger the bubble, allowing the user to perform a more intense and aggressive cleaning action.

There are different types of ultrasonic cleaning machines

Not all ultrasonic cleaning machines are the same. Let's take a look at several different types of ultrasonic cleaning machines on the market.

Industrial cleaning fluid: to put it bluntly, this cleaning fluid is high-grade, suitable for industrial-type main use. As a result, such cleaning cans are either very large or custom designed. Similarly, generators are stronger, bring more power, and the transducer class is large.

Lab size/desktop washer: there are many sizes of lab or desktop cleaners to choose from. The space occupied is smaller than the industrial cleaning machine, committed to the 24-hour operation and set up. People usually bring more parts to assist in the cleaning operation.

Small-scale systems: these systems are generally suitable for home or small-scale enterprise environments and provide the functionality of larger systems, but with less capacity and functionality.

Some mistakes about ultrasonic cleaning machine

Misconception 1: Aluminum should not be used in ultrasonic equipment

That's not true at all. In fact, aluminum is sometimes used to test the uniformity of ultrasonic cleaning machines. Be sure to check the reading instructions to make sure which metals are safe.

Myth # 2: Power doesn't matter

Some people think that you only need to buy an ultrasonic equipment, you can clean all types of dirt or pollutants. In fact, there are many variables that affect performance.

Myth 3: the longer the cleaning time, the cleaner the cleaning

For most cleaning methods can indeed clean clean, but ultrasonic cleaning is not. A complete cycle is required to complete the cleaning process; in general, if the equipment has sufficient power, there is no need to repeat the cycle of cleaning, which does no good to the cleaning machine.

It is very important to choose the proper cleaning method

The cleaning process begins with the selection of a suitable cleaning solvent. Do not use substandard cleaning solvents, but also expect the cleaning machine can be efficient operation. Please pay attention to and read the instructions before purchasing cleaning solvents. Many cleaning solutions are water-based, but not all items are suitable for cleaning.

Once the equipment requirements to confirm the correct and appropriate cleaning program, the rest is relatively easy. First, use a washing machine to remove contaminants and debris. Next, place the cleaned items in the accessories basket and insert them into the water storage tank. Turn on the machine and finish cleaning quickly. The standard cleaning time is about 10 minutes.

Take care of the washing machine

Ultrasonic cleaning machines are generally granted a manufacturer's warranty of nearly 2.5 years. If there is any damage to the washing machine, you can go to the factory for warranty.

If the equipment is wrong operation caused by equipment failure, it may be necessary to pay their own warranty and so on. Please follow the instruction to use the washing machine.
