Cleanliness is essential in people's daily lives to ensure optimal health and overall well-being. Not only that, it is also an important step for different industries.

Especially in industry, cleaning all kinds of hardware parts and equipment during the operation of the dirt generated. Traditional cleaning methods may involve manual labour, irritating chemicals and mechanical scrubbing; they are not suitable for products with complex shapes and are time-consuming and laborious.

Ultrasonic cleaning has become an alternative for different manufacturing industries. This method is very effective in reducing cleaning time and operating costs. In particular, the need to clean complex parts of the enterprise.

In recent years, the research and development of ultrasonic cleaning technology has produced a variety of ultrasonic cleaning machines available today. Choosing the right washing machine is essential to get the best results. Key features of the washer include frequency, ultrasonic and heating power, transducer type, and unit tank size. It is also important to understand the working principle, advantages and applications of ultrasonic cleaning machines.

Ultrasonic cleaning system

The industrial ultrasonic cleaning machine has three main components for the system operation: the generator, the transducer and the water tank. Each component is essential to complete the ultrasonic cleaning system, which is discussed in detail below.

Generator

Ultrasonic generator is the most important part of ultrasonic cleaning machine. The ultrasonic generator generates the high frequency electrical signal needed for the operation of the ultrasonic cleaning system. It is important that they control the frequency and ensure that the selected frequency and power output of the system is maintained. The performance of the whole ultrasonic cleaning system will be greatly affected by choosing the right generator.

The generator must be adapted to the production environment and meet the general cleaning application requirements of users. Operating voltage, size, and desired type of cleaning are factors to be considered in the search for a suitable cleaning system. Frequency determination, ultrasonic cleaning and heating power, and other controls are essential for each cleaning application. Once specific cleaning requirements have been determined, it is clear to select the correct frequency and corresponding sensors and cleaning tanks.

In general, low frequencies produce large cavitation bubbles that produce a strong cleaning effect on parts or assemblies of more complex materials. Higher frequencies clean parts or assemblies made of softer materials more gently than lower frequencies. In all cases, high ultrasonic generator power is required to fill the cleaning tank with ultrasound. The generator must produce a uniform waveform for the most efficient cleaning action.

Transducer

The second component required for an ultrasonic cleaning system is the transducer. A transducer is a device that converts alternating electric energy into vibrating mechanical energy.

Sink

The third component of the ultrasonic cleaning system is the water tank. The ultrasonic tank holds the cleaning fluid, which is made of thick stainless steel to maintain a high temperature and prevent rusting. When the generator generates an electrical signal, a transducer in the water tank converts the signal into a wave in the cleaning fluid. The cleaned parts are placed in the tank and immersed in the cleaning fluid, and the cavitation bubbles generated by the sensor remove all surface contamination.

The cleaning tank needs to withstand mechanical cleaning, vibration and temperature rise, and its structure also meets different cleaning requirements.

Standard tank sizes are available in stock to meet most cleaning requirements. However, when the ultrasonic cleaning system is a disposable device, the size of the cleaning tank can accurately accommodate normally cleaned components. Custom tanks are most effective for long, narrow or oddly shaped parts. Companies with specially shaped parts for ultrasonic cleaning also benefit from custom tanks. Ultrasonic cleaning system can be customized, including slot, frequency, etc. .

Features of ultrasonic cleaning machine

Standard ultrasonic cleaning machines have additional features that can be used for more advanced models in addition to conventional mechanical cleaning, but the cleaning and degassing modes are fundamental to all of our industrial ultrasonic cleaning machines.

Scan Mode

The scanning mode provides a slight change in ultrasonic frequency to oscillate ultrasonic power, preventing hot spots or areas with intense cavitation, as well as dead zones with little or no cavitation. Parts are being cleaned evenly using the clean mode operation. The cleaning mode prevents damage to extremely precise components or reduces the effect of standing waves in the cleaning tank.

Degassing mode

Degassing mode is used to remove trapped air in fresh cleaning solution to restrain cavitation. This step can be done in a unit even without a degassing mode.

A typical example is the importance of degassing a new ultrasonic cleaning solution before cleaning or sample preparation operations begin. The entrained air in the new solution interferes with the cleaning or cavitation of the sample preparation process until it is removed.

Ultrasonic cleaning equipment

Ultrasonic cleaning equipment ranges from small desktop devices to large systems for a variety of industrial applications. The size of the tank may determine the success of an ultrasonic cleaning application. The most direct application may require only a small water tank. However, industrial cleaning has more complex cleaning systems, including rinsing, adding process canisters and hot air dryers. Automation is often added to reduce labor and ensure process consistency.

Table type ultrasonic cleaning machine

Desktop cleaners are usually small and are commonly used in doctor's offices and clinics, laboratories, and jewelry stores. The institute also uses desktop ultrasonic cleaners for research. It is also used in other industries that require small, delicate parts to be cleaned.

Industrial ultrasonic cleaning machine

Industrial ultrasonic cleaning machine has more functions than desktop, can meet the needs of intensive industrial cleaning. At present there are four series of industrial ultrasonic cleaning machines with different additional functions.

These industrial ultrasonic cleaning machines are carefully designed to withstand intensive industrial cleaning. They have larger tanks, which hold up to 8,000 litres, and can clean large parts and machines. Compared with the desktop, these cleaners have a complete additional function, can complement the ultrasonic cleaning.

Purpose and application

With a wide range of machines, liquid solutions and available new functions, ultrasonic cleaning technology has many applications in different industries, making ultrasonic cleaning machine with multi-functional and functional.

Industrial Applications

The machined parts will be polluted by various substances during production. When a part is processed on a machine, traces of lubricant may remain on the part and may become contaminated throughout the production process; this can leave particles on the surface, and such contamination is harmful. Manual scrubbing is time-consuming and can damage or scratch parts surfaces. All parts can be cleaned by ultrasonic wave, leaving no residue or damage on the metal surface. Industrial ultrasonic cleaning machines provide an economical and efficient solution to meet these cleaning requirements.

Automotive applications

Parts used in the manufacture and modification of automobiles, as well as parts maintenance, must be thoroughly cleaned before use. New parts used in manufacturing are rarely contaminated, but even these parts can show signs of contamination by processing compounds and metals. Parts used for reconstruction and repair usually have large deposits of carbon or grease. Other pollutants in the industry include oil, gasoline residues or metal contaminants.

Electronic applications

Ultrasonic cleaning system can safely and effectively remove solder paste and flux residues in circuit components. When using ultrasonic cleaner to clean PCB after wave soldering, it is easy to start immediately after soldering as long as the PCB is cooled below 70 ° C before starting the ultrasonic PCB cleaning process.
