What Is the Definition of Ultrasonic and Megasonic Frequency?

Sound exists at much higher frequencies, which includes both ultrasonic and megasonic ranges. While these may not be audible to human hearing, these frequencies can be used in practical applications in megasonic and ultrasonic cleaning systems.

So how do megasonic and ultrasonic cleaning systems work? When liquids and gases are subjected to high-frequency sound at powerful energy levels, it leads to the formation of microscopic tears in these mediums.

When megasonic or ultrasonic sound energy goes through these mediums, it causes the microscopic tears to form into bubbles every second, and these bubbles collapse quickly. This process is known as “cavitation.”

Cavitation bubbles are high-energy bubbles. As each of these bubbles forms and collapses quickly, it generates shockwaves. When you place an object into these cavitation bubbles, it tends to be subjected to the energy of these implosions. These cavitation bubbles are so powerful that they can dislodge dirt or other contaminants off the surface of the object exposed. This is the kind of phenomenon which both the megasonic and ultrasonic cleaning system approach utilizes.

The megasonic and ultrasonic cleaning approach is revolutionary. This cleaning approach is faster, more thorough and more efficient. Since megasonic and ultrasonic cleaning systems are contactless cleaning systems, they do not require the use of harsh cleaning chemicals or mechanical scrubbing as conventional cleaning methods do.

The ultrasonic andmegasonic cleaning system approach are also environmentally friendly, since neither use cleaning chemicals. In conventional cleaning methods, they require the application of an involved chemical disposal system to meet compliance with environmental laws.

How Industrial Ultrasonic Cleaners Enhance Aerospace Safety

Aerospace parts and components used in rockets and aircraft need to withstand the extreme temperatures and operating conditions in which they are normally used. Part of the maintenance requires that they are cleaned from contaminants and checked regularly to maintain their functionality. Cleaning needs to be thorough to ensure that they won't malfunction during operation and put the passengers' and crew's safety at risk. Industrial ultrasonic cleaners are the better alternative in cleaning aerospace parts and components because they provide a more thorough and more efficient cleaning solution.

Ultrasonic cleaning systems work by generating an electric signal and converting it into sound waves inside the cleaning tank, which usually contains water (or water added with only a mild cleaning solution) and the part or component to be cleaned is immersed in it. With the ultrasonic sound waves travel through the cleaning solution, they produce pressure peaks and troughs.

Microscopic bubbles form in the pressure troughs and collapse in the peaks. These are called cavitation bubbles – high-energy bubbles that produce a powerful jet which removes contaminants from the surface of the object being cleaned. These bubbles can even clean inaccessible areas as well as irregular curves, holes and crevices of the contaminated aerospace parts, something which mechanical brushing cannot do. The result is a more complete and thorough cleaning action of these industrial parts.

Ultrasonic cleaning systems do not use harsh chemicals, intense mechanical brushing and pressure washing which are typical in conventional cleaning methods. With heavy contamination, conventional cleaning methods may not remove all the contaminants completely, and aggressive cleaning may damage parts or reduce their useful life.

High-Performance industrial ultrasonic cleaners deliver quick, thorough and comprehensive cleaning action that makes them suitable for a wide variety of cleaning applications. Since ultrasonic cleaning tanks do not involve the use and disposal of harsh chemicals, they are a safer and more environmentally-friendly choice for cleaning industrial parts.
