A simple ultrasonic bath - we assemble a device for domestic use with our own hands. Ultrasonic Cleaner (Professional Mini Ultrasonic Cleaner) How to use the ultrasonic cleaner

Throughout the development of mankind, certain inventions have regularly appeared, designed to simplify and improve people's lives. Technological progress never stands still, so the development of the scientific sphere is a completely natural and logical process.

Not so long ago, such a device as an ultrasonic bath gained popularity among consumers. Almost any owner can create this mechanism with his own hands, it is only important to have a certain list of materials available and strictly follow the manufacturing technology. This product is used mainly to clean certain objects, while the work is based not on standard methods, but on the use of such a relatively new phenomenon as ultrasound. Therefore, what is an ultrasonic cleaning bath, and how it functions, will be discussed further.

Principle of operation

From the name of this device it becomes clear what underlies its functioning. Ultrasound is a kind of vibration, the frequency of which exceeds 18 kHz. The liquid that is in such a bath is filled with a large number of bubbles, which burst under the influence of high pressure, creating an effect called cavitation.

The principle of operation is as follows: an object requiring cleaning is immersed inside the tank with a solution. After starting the device, the bubbles, bursting, act on the contaminated mechanism and remove plaque from it. This method allows you to get rid of dirt even in the most inaccessible parts of the product for manual processing, without violating its structural integrity.

What does an ultrasonic cleaning bath consist of?

Outwardly, this device is not very large, about 1 liter (there are samples of a larger size, containing 5, 10 or more liters), made, as a rule, of stainless steel. This is quite enough to process a variety of devices and mechanisms.

The design of such a product includes 3 main elements:

1. The emitter, the main purpose of which is to convert electrical vibrations created by ultrasound into mechanical vibrations, which are subsequently transferred to the bath liquid through its walls.
2. A generator that serves as a source of vibration.
3. A heating element. Its main function is to make the ultrasonic bath liquid have a constant temperature of 70°C. It is worth noting that sometimes such a structural component may not be included in the design of the device, but its presence definitely contributes to better cleaning.

Scope of ultrasonic baths

This method of removing dirt is much more effective than traditional options. To clean a wide variety of products, an ultrasonic bath is actively used in many areas:

• in medicine, its use allows thorough sterilization of surgical and laboratory instruments;
• in the engineering field, an ultrasonic bath plays the role of a unit that removes contaminants from pipes and other large parts after they have been polished and polished;
• these devices are widely used in jewelry, when periodically there is a need to clean jewelry that has lost its presentable appearance;
• employees of the printing house use an ultrasonic bath primarily for washing the structural parts of printers and other devices responsible for printing;
• the use of this multifunctional device also helps to clean silicon and quartz wafers, which form the basis of electronic production;
• motorists know firsthand about the need to clean the structural components of the vehicle, such as nozzles, filters, injectors, etc.

The main advantages of ultrasonic baths

If we compare such a system with other devices, then we cannot fail to note a number of its undeniable advantages, including:

1. An ultrasonic bathtub is a very easy-to-use product. For its functioning, it is only necessary to fill the container with the necessary solution, and the cleaning process can begin.
2. Any contamination even in the most inaccessible parts of an object can be removed with its help without any problems.
3. High performance indicators. The ideal result of cleaning a thing can be achieved by holding it inside the bath in just 2-3 minutes.
4. After the end of the procedure, no mechanical damage will appear on the surface of the product, since its processing takes place without the use of any aggressive means.

Main selection criteria

In order for the purchased ultrasonic bath to work as efficiently as possible, you need to familiarize yourself with some factors that affect the quality of its work.

As mentioned earlier, the presence in its design is welcome, since the cleaning time in this case is significantly reduced, and the positive result is more obvious. However, it should be noted that if the ultrasonic bath liquid contains a disinfectant solution, then it is not necessary to use additional energy to increase the temperature.

In addition, it is important to immediately determine which items will be cleaned, since the capacity of the device must correspond to the volume of products immersed in it.

Next, a few words should be said about how to make a similar device for removing dirt from automobile nozzles. It is these parts of the vehicle that most often require cleaning, so the specifics of the work must be described in more detail.

Materials for the manufacture of ultrasonic bath for nozzles

Every car owner knows that for the stable operation of the engine it is very important to keep all its components in order. When an ultrasonic bath is used, it is safe to talk about the safety of the vehicle. However, such work performed at any service station will be very expensive. Therefore, you should figure out what ultrasonic baths for nozzles are in order to make such a device yourself.

But first you need to decide on the list of materials required for self-assembly. These include:

• A container that will serve as the basis. She can be any not too large basin.
• Washing machine with ultrasonic function. You can buy such a device in almost any household supply store.
• The simplest washing powder that does not have impurities and additional properties like a bleaching effect.
• Hot water.
• If available - a special spray for cleaning nozzles. However, it is quite possible to do without it.

Self-made ultrasonic bath for nozzles

The process of creating such a unit does not carry any complexity. To begin with, you should take a clean basin and draw hot water into it, in which you subsequently need to dilute the washing powder in approximately the same proportion as for washing. After that, the nozzles that need to be cleaned should be immersed in the liquid and lowered. Its operation time is about 30 minutes. At the same time, it is important to remember that the water in the basin should be changed until the smell of gasoline completely disappears during the operation of the device.

After the unpleasant odor is no longer felt, the nozzles should be placed directly in the center of the device, which will speed up the cleaning process. 6 hours is the standard time for which the bath should operate. will completely remove dirt and oil residues from car parts. In addition, this cleaning option will enable the owner to save a significant part of the financial resources.

A set of materials for mounting an ultrasonic bath

In order to construct such a device with your own hands, it is important to correctly understand the principle of its operation, otherwise complex manipulations will not lead to anything good. Having studied the features of the functioning of such a mechanism as an ultrasonic bath, you can assemble it with your own hands, having the following list of materials available:

• plastic or glass tube;
• a round magnet (such a detail can be found in many old speakers);
• coil;
• liquid intended for ultrasonic bath;
• porcelain container;
• pulse-based transformer;
• pump;
• steel frame.

After all the parts are prepared, assembly can begin.

Manufacturing process of ultrasonic cleaning bath

As mentioned earlier, such work must take place in strict accordance with a pre-prepared plan, so that the end result is positive. The diagram of an ultrasonic bath, which is displayed below, will help to understand the device of a home-made device.

The installation process begins with the fact that the coil must be wound on a prepared plastic or glass tube. A magnet should be placed on the remaining section of the rod. The resulting device is nothing more than a transducer called magnetostrictive.

All the following actions must be carried out according to the following algorithm:

1. A porcelain vessel should be installed in a steel frame.
2. After that, the bottom of this part should be equipped with a hole where the already manufactured converter should be placed.
3. Then, in the design of the vessel, it is required to build nozzles. These elements are designed so that liquid enters through them and subsequently drains. In the event that it is planned to design a large bath, it would be useful to take care of installing a pump that accelerates the flow of the solution.
4. At the end of the installation, an impulsive transformer is installed, the main function of which is to increase the voltage. For these purposes, any mechanism of this kind, taken from a TV or computer, is suitable.

The work is completed by checking the functioning of the ultrasonic bath. If the assembly process was performed correctly, then the operation of such a device will save a significant part of the budget and will make it possible to thoroughly and efficiently clean all the necessary parts.

An ultrasonic bath is a pretty useful household item. It will help to clean various objects from dirt, plaque or rust. A few years ago, ultrasonic cleaning of objects was considered fantasy or something unrealistic. Today, it is an effective way.

Such a bath can be made independently using improvised materials.

What is an ultrasonic bath?

Such a device can be purchased for little money in Chinese stores. But many masters do not trust their quality and try to collect such baths with their own hands.

Indeed, in almost every jewelry workshop or in a workshop where mobile phones are repaired, there is such an ultrasonic bath. Compared with mechanical cleaning methods, the ultrasonic method has several advantages:

• removes dirt in hard-to-reach areas, it is especially useful for jewelry with complex patterns and printed circuit boards;
• cleaning speed - all dirt is removed quickly and the master does not need to manually wash anything additionally and waste time on this;
• After cleaning, there are no mechanical damages.

For what devices and things can an ultrasonic bath be used?

• for the restoration and creation, repair of jewelry;
• in workshops where electrical devices and circuits of these devices are repaired;
• in medical institutions and chemical laboratories, where you need to thoroughly clean the working tool;
• in workshops where vehicles and circuits are repaired;
• in watch shops where there is a need to carefully and safely clean small parts.

How to use an ultrasonic bath?

The presented device works according to the scheme sound pressure cavitation, which are formed under the direct influence of ultrasound. It turns out that a large number of bubbles appear in the liquid and when they burst, the effect of sound pressure is obtained.

In a liquid medium, ultrasonic waves propagate just as well as in air. It turns out that each bubble that bursts creates the effect of a microexplosion. When there are a lot of bubbles, and, accordingly, a lot of explosions, pressure is created in the bath, which is enough to exfoliate particles of dirt or rust.

Types of ultrasonic baths and pollution cleaning schemes

1. Industrial ultrasonic baths - first of all, they differ in their dimensions. The working volume of such baths can exceed 10 liters. The minimum volume of an industrial bath is 4 liters. Almost all devices are equipped with additional functions, such as liquid heating, timer, high-quality nozzles, additional settings for deep cleaning of devices.
2. Portable ultrasonic baths are small devices, with a capacity of less than one liter. Used for cleaning small parts at home or small workshops. More simple models have a simple design and a minimal set of functions.
3. Semi-professional small baths - they have volumes up to 4 liters. Equipped with nozzles, additional control or cleaning functions. Often have electronic control, timer. The tank is made of stainless steel.

What is unique about cleaning parts with ultrasound?

Ultrasound is a term from physics. This is the level of noise that is beyond the hearing of a person. The range of ultrasound oscillations is from 16 to 1000 kHz. By studying ultrasound, scientists have found that it is able to cause a kind of “boiling” of a liquid, during which the bubbles do not float to the surface, but explode. This causes additional waves. Conventionally, the process was called “cavitation”. It was he who formed the basis of the ultrasonic bath.

The size of the bubbles in the vessel depends on the pitch of the sound, the higher it is, the smaller the bubbles. Thanks to this phenomenon, in such devices it is possible to push out dirt from harder surfaces. It is important to consider that the higher the frequency index, the smaller the bubbles and the less they damage the surface of the parts. At a relatively low frequency, small bubbles can leave “marks” on the surface of parts, at the level of the smallest particles.

What do you need to create an ultrasonic bath with your own hands?

In order to create a bath with your own hands, you will need:

• a container made of stainless steel (it must be borne in mind that any field of activity requires its own bath size. For example, a small container is suitable for cleaning jewelry. And for a workshop for working with electrical appliances or for car repair, a much larger container is needed);
• an ultrasonic generator that creates the necessary vibrations;
• nozzle;
• device control unit, with which the cleaning parameters and the duration of the device are created;
• transducer - emitter of electrical vibrations, which are converted into mechanical ones and transmitted to the walls of the ultrasonic bath;
• round magnet (you can take a magnet from old speakers);
• coil with ferrite core;
• a small pump that will supply liquid to the container;
• a small tube made of clear plastic or glass.

It is important to remember that the ultrasonic bath itself does not clean the product. , and clears it, enhancing the effect of the solvent. Therefore, it is very important to correctly select the liquid for ultrasonic baths that will correspond to the type of contamination of the object.

It is forbidden to turn on a half-empty or empty bath. The liquid level in the container should always be checked before use, it should be ⅔ from the side. If there is too little liquid, then the load on the generator increases and it may break.

If you have all the necessary parts for making an ultrasonic bath - tubes and coil, nozzle, magnet, etc. - you can get to work. First, a ferrite coil is wound on a glass or plastic tube. In this case, you need to make sure that the ferrite rod hangs freely, it does not need to be strongly fixed. The magnet is attached to the end of the rod. From this comes the design of the emitter.

Drill a hole in the bottom of the vessel. It can be a ceramic or porcelain container. A hole is needed to insert a pre-made emitter into it. After this vessel is fixed in the bath. Then you need to attach the pipes for draining and supplying liquid.

It is worth noting that the solution enters the ultrasonic bath better if a pump is installed in it. By raising the voltage, a pulse transformer provides more efficient operation. This device can be taken in an old computer or TV.

After the initial assembly, the device must be tested. All malfunctions are best eliminated during testing, so it is important to pay special attention to testing the device.

During the inspection, the following rules should be observed:

• you can not turn on the unit without liquid, this can break the inner rod into pieces;
• before starting, it is better to inspect the appearance of the device, whether everything is connected correctly and whether it is well fixed;
• it is strictly forbidden to touch the product that is inside the ultrasonic bath at the time of cleaning.

Working with ultrasound requires strict adherence to safety rules when working with electricity.

Structural features of an ultrasonic bath

The main mechanism of this device considered to be an emitter. It transforms electrical oscillations into mechanical ones, which contribute to the purification of products. How well the parts will be processed depends on the correct functioning of the frequency generator and the heating element. In the bath, you must always maintain the temperature of the liquid no more than 70 degrees.

Particular attention should be paid to the liquid poured inside. Manufacturers of such ultrasonic baths recommend buying special liquids, such as Flux-off, Zestron FA +, Solins-us and analogues. Practicing masters actually use various options - and distilled water, and alcohol, and a solvent.

• gasoline "galosh";
• any window cleaners that contain alcohol in their composition;
• acetone, which can be used for metal objects;
• distilled water.

If it is necessary to clean an object from rust, it is recommended to take a solution of phosphoric acid and water. Or take a special rust converter. For example, a water-based solution Antinakipin.

Technological progress does not stand in one place, devices to facilitate human labor are gaining more and more popularity. Products consisting of many compounds and elements may break due to the presence of surrounding aggressors. In some cases, it is enough to clean the mounts and boards from dirt, but it is not possible to get close to hard-to-reach places. An ultrasonic bath is increasingly being used for cleaning.

What is an ultrasonic bath?

High frequency waves can act on materials in a corrosive environment. The principle of operation of an ultrasonic bath is to place the parts in a special liquid, then the components move under the influence of waves. An increase in pressure leads to the process of cavitation at the molecular level, the formed bubbles explode during the movement of atoms. How to use an ultrasonic bath, you can learn from the instruction manual for the product, pressure is applied to various materials in the necessary proportions.

The ultrasonic bath consists of a liquid bowl made of stainless metal alloys. For domestic use or cleaning of small products, a bath with a volume of up to a liter is used. Industrial production uses large volumes of bowls that can clean bulky items. The frequency and range of ultrasonic waves operates in modes from 18 to 120 kHz, sounds at such levels are not audible to humans. Impact st Ultrasound occurs in various fields, from hospitals to jewelry workshops, with certain skills it is possible to make an ultrasonic bath with your own hands.

Types of pollution

Various application environments make the ultrasonic cleaner a versatile device. The mechanism has found its main application in car services and industries, where it is necessary to remove the following types of pollution:

• solid deposits that appear during the operation of mechanisms;
• protective film coatings are removed before joining by soldering or inside products that interfere with normal operation;
• oxidation and corrosive deposits.

In a do-it-yourself ultrasonic bath, it is possible to wash printed circuit boards and other radio engineering materials. Before use, it is enough to immerse the part in the liquid, start the process.

Design features

The main component of the system, the emitter, is responsible for the work. Its purpose is to convert electrical energy into mechanical vibrations. The impact of energy occurs on the part through the wall of the device, as a result of which the cleaning process occurs. The ultrasonic bath includes a frequency generator whose device is responsible for generating waves by applying electrical vibrations.

The design of the ultrasonic bath

High-quality cleaning of parts is achieved by exposure to a wave at a certain temperature. The heating elements control the temperature of the liquid according to the set parameters. Impulse work requires the control of processes occurring during the processing of parts by ultrasound. Cleaning of parts is carried out in stages:

• the purified solution is poured into a container;
• the object is lowered, for better impact, stands are used so that the part is in the middle of the bowl;
• after turning on the device, bubbles form on the surface of the liquid;
• bubbles act on the part in hard-to-reach places, cleaning the dirt.

Processing of parts takes a long time, depending on the amount of contamination. Large deposits can be sonicated for up to 10 hours.

Application Benefits

A device purchased or made by oneself has a number of advantages over mechanical action on parts. The main advantages of using an ultrasonic bath:

• No waste of time, interaction with the part of the cleaning process is excluded, only intermediate control is necessary.
• The chemical does not harm human health under certain conditions. It is enough to wear rubber gloves when in contact with the machined part.
• Mechanical cleaning is not possible get rid of quickly and effectively from plaque and dirt in hard-to-reach places. Ultrasound will help you get to all the cracks and corners of the part without leaving dirt.
• Exposure of the part to ultrasound reduces to zero the risk of getting a damaged part as a result. Mechanical damage is excluded, which cannot be said about the mechanical cleaning method.

The scope of the ultrasonic bath is wide, the device is sold on special portals of household appliances or specialized outlets.

How to make an ultrasonic bath with your own hands

Before assembling an ultrasonic bath with your own hands, you need to figure out what offers are available on the market.

There are several types of bathtubs offered by manufacturers:

• Portable devices are used in the household, as well as in the processing of small products. The volume of the bowl varies from 1 to 2 liters, such a device costs from 5,000 to 20,000 rubles.
• Industrial modifications are used by large industries, car services, they allow you to process a large number of products at a time, the price can reach up to 50 thousand rubles.

Do-it-yourself ultrasound generator

With certain skills, it is possible to make an ultrasonic bath with your own hands. If you have the tools and access to accessories that are sold by radio parts stores, you can save up to 3 parts from the cost of a new device. For self-production, you will need the following elements:

• Container for immersion of products made of stainless steel. It should stand firmly in place, have a slight rise to access the bottom.
• Tube made of glass or plastic.
• A pump for pumping liquid, suitable for low power, its price is not so high.
• Magnet in the form of a circle, it is possible to dismantle from unused speakers.
• Coil with ferrite core, ceramic or porcelain court.
• Pulse transformer, sold by points of sale of radio components, the price starts from 300 rubles.

Also, for work, you will need liquid and power from a 220-volt electrical network.

Do-it-yourself ultrasonic bath assembly

After preparing all the materials, you can start assembling the ultrasonic bath with your own hands. The first step is to wind the ferrite wire around the plastic tube, the rod can be free-form, stable fastening is not required. The magnet is attached to the end of the rod, the result is a magnetic friction emitter.

The next step involves drilling holes with your own hands at the bottom of the bathtub tank. The vessel is attached to a steel container, holes are made nearby for supplying and draining the liquid. Nanos will help to quickly carry out the operations of supplying liquid to the bath; for draining, you can get by with a regular hose connected to the tank.

The pulse type transformer produces an increased voltage current, which increases the efficiency of the device. For lack of access to radio components, you can remove the transformer from an unusable TV or telescopic monitor. After assembling and connecting all elements of the ultrasonic transformer, a test run is performed. In the process of work, it is important to follow the safety rules, do not use the device without liquid, do not touch the part during processing.

What liquid is used in an ultrasonic bath

Liquid for ultrasonic baths can be found on sale less often than the device itself. To influence the parts to be cleaned, two solutions are used:

1. A solution of a surfactant with water is used to purify precious metals.
2. Alcohol based solution. The liquid that is used when cleaning circuit boards and microcircuits perfectly prevents the formation of corrosion on parts over time.

There are various options for solutions that are used at home. Some owners of ultrasonic baths use diesel fuel or gasoline, working with such elements requires increased care, because. they are explosive. It is independently possible to make a liquid from the main components of a powder or detergent.

Rules for the operation of ultrasonic baths

Working with the device does not differ in its design or manufacturer. A bathtub made by oneself, or purchased on the market, requires compliance with some safety rules. Also, the mechanism can simply break down if you do not follow the rules:

• The installation of the part is done only by wearing rubber gloves, this is due to the aggressive environment of the liquid, which can lead to allergies or other skin damage.
• The launch of an empty device is categorically excluded. When working with homemade structures, the ferrite rod may shatter into pieces under the influence of high-frequency electricity. In purchased devices, a shutdown function is installed in the absence of liquid.
• Before starting, it is important to inspect the body of the device for signs of leakage and other damage.

It is important to monitor the technical condition of the electrical circuit, short circuits, overheating of the transformer during prolonged use of the ultrasonic bath are not ruled out. When working with small parts, it is possible to save processing time and liquid, it is enough to place the part in a glass of liquid, then to the device filled with ordinary water.

Scope of ultrasonic baths

Based on the use of ultrasound, many parts are cleaned. The affordability of the design makes the use of ultrasonic baths in various industries more and more popular.

1. Jewelers use a bath to clean old pieces of soot and dirt. Hard-to-reach places can be easily cleaned using a special solution. The method is important because there are no traces of mechanical influences on the parts, which is especially important when working with antique parts.
2. Optical products, all kinds of lenses can be easily cleaned with ultrasound.
3. The electronic industry is used when processing old circuit boards, it is impossible to clean the elements of radio engineering by mechanical action, there is a possibility of damaging important connections.
4. The chemical industry has identified the device as a possible mechanism for accelerating processes through cavitation effects.
5. The automotive industry and printing stations use ultrasonic machines to wash mechanisms and assemblies.

Also, the device is widely used by car services when cleaning carburetors, injectors, throttle valves. Some mobile device repair centers use a bath to clean solder build-up from small parts.

Selection rules

Before choosing a bath, you should pay attention to many parameters, the main of which, if chosen incorrectly, can exclude the performance of work. Its price and power directly depend on the size of the device. Some modifications are equipped with touch panels for easy control. Cleaning small objects does not require an increased volume of the bowl, on the contrary, an increased volume requires a greater consumption of liquid, which cannot be reused.

One of the important criteria is the presence of a heating element that maintains the temperature of the liquid within certain limits. Heating is performed for a faster process, saving time for cleaning the product. The timer will allow you to set a certain time, notify when work is completed.

It is necessary to pay attention to the presence of a set of special clamps and baskets that will facilitate the immersion of the part into the container.

Ultrasonic bath repair

Regardless of the quality of the device, the use in an aggressive environment causes the need for repair. Maintenance and repair of an ultrasonic bath is not available for every service, due to the lack of qualifications of the craftsmen.

Self-repair of the mechanism includes a preliminary visual inspection. Surface analysis begins with checking the cable for breakdowns, no fluid leaks and rumbles inside the case, after which it is necessary to check:

• an electronic board attached to the bottom of the mechanism;
• batteries;
• piezo emitter;
• power switch or timer.

Ultrasonic bath diagnostics

Diagnostics of a specific node can be performed independently, the best would be the ability to install a failed element on another device. Some instructions describe how to carry out maintenance in sequence, it is better to follow the manufacturer's recommendations for safe operation and quick effect.

How does ultrasound work?

Ultrasound is a frequency fluctuation that is greater than 18 kHz (18,000 counts/sec). As a result of these vibrations, many tiny vacuum bubbles are formed in the liquid of the ultrasonic bath. During the high pressure phase, they explode, creating highly effective pressure waves. This process is called "cavitation" and with the help of it the particles of dirt are removed from the objects being cleaned in the ultrasonic bath.

The lower frequencies around 20 kHz used in ultrasonic cell disruption baths produce larger bubbles and more powerful pressure waves than the 35 kHz frequencies used for intensive but gentler cleaning. In order to achieve the effect of ultrasound in liquid, the high frequency generator converts the mains frequency to the corresponding frequency of the ultrasonic instrument. This frequency is then transformed into mechanical vibrations using the electromechanical transducers of the ultrasonic bath.

Benefits of Ultrasonic Cleaning

Ultrasonic cavitation allows you to quickly remove dirt from products, even from hard-to-reach places, such as cavities and holes, it can penetrate deep into the pores. Ultrasonic cleaning is superior to other cleaning methods and only takes a few minutes. In addition, ultrasonic cleaners provide gentle cleaning without mechanical damage such as scratches.

Advantages in production technology and sonochemistry

Cavitation in ultrasonic baths can be used not only to clean various objects, but also to contribute to a longer preservation of the oil and water emulsion compared to other production processes. For sonochemical processes in an ultrasonic bath, the reaction vessel must have a thin bottom. Thus, ultrasonic energy is propagated directly and efficiently into the reaction vessel.

How to choose an ultrasonic bath?

SONOREX ultrasonic cleaners operate with an intense cleaning frequency of 35 kHz. The size and number of objects to be cleaned determine the size of the ultrasonic bath.

When choosing an ultrasonic bath, consider the dimensions of accessories such as baskets. To avoid overloading, it is recommended to choose a slightly larger ultrasonic bath.

Should the ultrasonic bath be heated?

Cleaning agents heated in an ultrasonic bath reduce cleaning time and help remove dirt more quickly. For cleaning processes in laboratories, it is preferable to use heated ultrasonic baths.

Disinfectants must not be heated, since protein coagulation begins at 40 0 ​​C. Therefore, it is recommended to use ultrasonic baths without heating for disinfection.

What type of ultrasonic bath accessories should I use?

Cleaning objects and reaction vessels must not be placed on the bottom of the ultrasonic bath. The baskets avoid scratches on the parts to be cleaned and on the bottom of the ultrasonic bath. Beakers are placed in perforated ultrasonic bath lids and used for cleaning small objects or when working with aggressive solutions.

What cleaning agents can be used in an ultrasonic bath?

TICKOPUR and STAMMOPUR cleaners and disinfectants have been specially developed for use in SONOREX ultrasonic cleaners. Water without appropriate additives does not clean.
Never use household detergents and deionized water in ultrasonic cleaners. Plastic inserts for ultrasonic baths must be used when working with acids or removing acidic residues. Flammable liquids must not be used directly in the ultrasonic bath.

Top 20 ultrasonic cleaning questions and answers.

Ultrasonic cleaning: questions and answers

1. What is ultrasonic cleaning?

Ultrasonic cleaning is a fast and efficient environmentally friendly cleaning method that uses ultrasonic energy that is passed through a suitable cleaning solution. This provides high-speed thorough removal of unwanted contaminants from the cleaned elements located inside the liquid container, subjected to the penetration of ultrasonic waves. This cleaning method is one of the most modern and effective ways to remove dirt from various objects, especially in the shortest possible time and without possible damage to the elements. The ultrasonic cleaning method is based on cavitation.

2. What is cavitation?

Cavitation is the process of rapid formation and dispersion of micro bubbles in a liquid. The phenomenon of cavitation occurs when ultrasonic waves travel through a liquid. Ultrasound (high frequency sound, typically 20 to 400 kHz) produces alternating high and low pressure waves that produce tiny cavities (bubbles). They begin to grow from microscopic size in the low pressure phase until they contract and then burst in the high pressure phase. The molecules of the liquid collide, releasing a huge amount of energy. The energy instantly increases the local temperature and generates a high energy flow directed to the surface of the object being cleaned. These bubbles have a huge energy, which is aimed at cleaning - its release separates contaminants from the surface being cleaned.

3. How to get an ultrasound?

The ultrasonic energy of high frequency sound waves is converted from high frequency electrical energy by a transducer. The cleaning power of the device depends on the type and power of the converter used.

4. How is the ultrasonic bath designed?

The ultrasonic bath module includes an ultrasonic generator and special transducers mounted on the bottom of a stainless steel tank. The tank must be filled with liquid to form the cleaning medium. The generator together with the transducer form alternating waves of compression and expansion in the liquid at very high frequencies, usually from 25 to 130 kHz.

5. What is the ultrasonic heater used for?

The ultrasonic cleaner uses a heating function to keep the solution at the right temperature between cleaning cycles. In turn, the heat needed for cleaning is generated by the cavitation process.

6. What is degassing and why is it needed?

Degassing is the process of preliminary removal of gases that may be present in the cleaning fluid. Cavitation should only occur after all gases have been removed from the cleaning solution. This provides a vacuum in the bubbles that form. They are destroyed when a high pressure wave hits the bubble wall and the released energy assists the detergent in breaking the bonds between the objects to be cleaned and their contaminants.

7. How to get the best cleaning result?

You can get the best ultrasonic cleaning result only after following these simple steps: choose the right type of ultrasonic bath and the right size tank; choose the appropriate cleaning agent suitable for your purposes; set the correct temperature and cleaning time.

8. What is direct and indirect cleaning?

When you place the items to be cleaned in the tank of the ultrasonic bath filled with cleaning solution, this is called direct cleaning. Objects are usually placed in a special perforated plastic tray or basket rather than on the bottom of the tank. However, for direct cleaning, you must choose a liquid that will not damage the tank of the ultrasonic cleaner. Otherwise, you can use a non-perforated tray or glass container, fill it with the cleaning liquid you need, and place the items inside. This method is called indirect cleaning. Keep in mind that the water level inside the tank should reach the fill line during cleaning, that is, about 3 centimeters from the top.

9. Why is a special cleaning solution needed?

You can use a variety of cleaning fluids, even clean running water. However, water itself does not have cleansing properties, so you will need to use a special cleaning solution to get the desired effect. You place objects to be cleaned in the solution to start this process, and cavitation helps the solution break the bonds between parts and contaminants. Special cleaning solutions contain certain ingredients to enhance the ultrasonic cleaning effect. For example, a decrease in the surface tension of a liquid leads to an increase in the level of cavitation. The liquid contains an effective wetting agent or surfactant.

10. What cleaning solution should I use?

You can find a wide variety of ultrasonic cleaners designed for specific applications. Modern solutions contain various detergents, wetting agents and other reactive components. The correct choice of cleaning solution determines the success of the cleaning process and helps to avoid unwanted reactions with the object being cleaned. Please consult our technical experts before choosing a product for your needs.

11. Which cleaning solution should not be used?

Never use flammable solutions or liquids with a low flash point (gasoline, benzene, acetone, etc.). The energy caused by cavitation generates heat, and high temperatures can form a hazardous environment in combustible solutions. Avoid using bleaches and acids. They can damage the stainless steel tub. Otherwise, if necessary, use them carefully, however, only for indirect cleaning. An appropriate container for indirect cleaning should be available, glass containers may be used.

12. When should the cleaning solution be replaced?

13. Why is it necessary to maintain the solution level at the level indicator mark?

Each time before cleaning, make sure that the level of the solution is in line with the bath level indicator. It should match the level indicator with trays and a basket inside. Otherwise, the characteristics of the cleaning process may be affected, the cleaning frequency may change, the cleaning efficiency may decrease, and your ultrasonic bath may even be damaged. Following this requirement allows for a higher circulation of the solution around the objects being cleaned and protects the heaters and transducers of the device from overheating and shock.

14. What is the duration of the cleaning process?

Cleaning time depends on a number of conditions, the most important of which are: cleaning solution, amount and type of contaminants in the facility, cleaning temperature and required level of cleanliness. You can observe the removal of contaminants immediately after the start of the cleaning cycle. You can adjust the duration of the cleaning process according to your needs. Usually, you will have to set approximately the required time, then check the result of the cleaning, and repeat the cleaning cycle if necessary. The actual use and result of cleaning helps the operator to determine the optimal time for certain types of objects as well as for specific types of dirt.

Heating helps the bath to make the cleaning process faster and more efficient. Usually cleaning solutions are formulated to provide better results and higher temperatures. You can determine the optimum temperature that suits your needs to provide the fastest and most effective results by experimenting with different types of dirt and objects being cleaned. Generally you can get the best results within 50°C

16. Should I rinse the parts after cleaning?

To remove any harmful or unwanted chemical residue from the cleaning agent, it is recommended to rinse the objects after cleaning. You can rinse in your ultrasonic bath filled with plain tap water, or use tap, distilled or deionized water and a separate container if needed.

17. Why should the ultrasonic bath be turned off when not in use?

Continuous operation of the bath increases the evaporation of the cleaning solution. This can cause the liquid level in the tank to drop, which can result in serious damage to the bath. Turn off the ultrasonic bath after completing the cleaning cycle and check the level of the solution before each operation in order to ensure the long life of the device.

18. Can ultrasonic cleaning damage my parts?

This cleanup method, with some caveats, is considered safe for most objects. Although a powerful release of energy occurs during cavitation, it is safe, since the energy is localized at a microscopic level. The first thing you should pay attention to is choosing the right cleaning solution. The ultrasonic power can increase the effect of the detergent on the items being cleaned. It is not recommended to use ultrasound to clean the following stones: emerald, malachite, pearl, tanzanite, turquoise, opal, coral and lapis.

19. What are the applications of ultrasonic cleaning?

Typically, this cleaning method is used to clean objects, parts and other objects with complex surface structures and objects that require special care. Ultrasonic cleaning will be useful in chemistry, automotive, engineering, polymer products, scientific research, health care, medicine, weapons, jewelry and other industrial applications.

20. What is prohibited when using an ultrasonic bath?

• Never place objects on the bottom of the cleaning tank. This can damage the bath as the ultrasonic energy is reflected back onto the transducers from the objects to be cleaned. Always use a cleaning tray or basket, ensuring that there is a 30 mm distance between the bottom of the tank and the objects to be cleaned.
• Do not drop the ultrasonic bath and avoid other shocks. This may damage the ultrasonic transducer.
• Never run a bath without liquid inside the tank.
• Never use flammable liquids such as gasoline, benzene, acetone for fire hazard reasons.
• Never use the ultrasonic bath in very dusty places.
• Never use the ultrasonic bath at very high temperatures for extended periods of time.
• Never attempt to clear explosive objects, ammunition, hand grenades, mines, etc.
• Never put animals or other living creatures inside the bath and do not use the bath to clean your pets.
