Ultrasonic Cleaning of Large Diesel Engines
With increased regulations limiting shop time, labor and access to harsh chemicals, many engine builders are opting for more automated solutions that are also more friendly to the environment.ultrasonic cleaning of large diesel engines Ultrasonic cleaning is a highly efficient process that can clean even the largest diesel engines with ease. In fact, diesel remanufacturers are beginning to turn to this technology as their main method for cleaning large diesel engine parts. In a way, ultrasonic cleaning of large diesel engines and other automotive components has revolutionized the entire industry, making it a vital step for shops to take to become more competitive and profitable.
In the past, many shops used an extended soaking period and manual scrubbing to get their diesel parts clean. But now, with the introduction of ultrasonic cleaners, employees can simply place an engine block or other large diesel component into an appropriately sized ultrasonic cleaning tank and set a timer. This will allow them to go on to other work in the shop, while the ultrasonic cleaner will do the work for them. The ultrasonic frequency and temperature of the cleaning solution can be adjusted to suit the specific needs of each application.
What Contaminants Can Ultrasonic Cleaning Remove?
Using sound waves, an ultrasonic cleaning system generates microscopic bubbles in the cleaning solution through a process called cavitation. When the bubbles implode, they release high-energy microjets that dislodge contaminants from the surface of the part. This can include carbon deposits, grease, polishing compounds, oils, soot, fingerprints and more. This action is particularly effective on surfaces with tight crevices, as well as blind holes and cracks.
Ultrasonic cleaning is able to reach into the smallest crevices of large diesel engine parts, including fuel injectors and nozzles. This is important for a precise, accurate and reliable diesel remanufacturing process. In addition, ultrasonic cleaning is non-destructive, preserving the dimensional integrity of the part and not damaging the delicate surface coating.
Another benefit of using an ultrasonic cleaning machine is its ability to clean complex components with intricate geometries and delicate surface coatings, such as a diesel fuel filter or brake assembly. The ultrasonic cleaners can be programmed to create a specific vibration pattern to ensure that all parts are thoroughly cleaned. This helps to reduce rework and repair costs, as well as improve the quality of the final product.
The ultrasonic cleaning machines are powered by electric ultrasonic wave generators that use piezoelectric crystals to produce mechanical vibration. This vibration is transmitted to a cleaning solution that’s been placed in the cleaning tank or tub. The ultrasonic frequencies create cavitation within the solution, causing it to vibrate. This in turn creates a scrubbing action that dislodges the contamination and allows it to be rinsed away.
Although there are a wide variety of different sizes and types of ultrasonic cleaning machines, most of them consist of a tank that can hold an adequate amount of liquid, along with electric ultrasonic transducers and an electric current to power the generator. The ultrasonic waves vibrate the solution, creating cavitation and forcing it to agitate. This action is particularly effective on hard surfaces, as well as cracks and blind holes.
