15L Ultrasonic Cleaning Device SUS304 Tank 1-30 Mins Timer Adjustable For Jewelry

How To Use Whale Cleen sonic Ultrasonic Jewelry Washer?

Ultrasonic cleaners are pretty easy to use. Just lower the parts to be cleaned into the tank, turn on the system and, voila, the cleaning begins. You can turn on the system using either control knobs or digital controls.

Also, by adjusting sound wave frequencies, you can change the number and size of bubbles or collapse them altogether. Note that, since there is a direct link between the frequency and the number of implosions, ultrasonic cleaning offers a very high level of process control; higher frequencies are better for removing very small particles.

Tips for choosing an Ultrasonic Jewelry Cleaner:

Operating Features

As noted above ultrasonic jewelry cleaners range from those with a simple on-off unit to those with features that are important to fast, thorough and safe cleaning. Ultrasonic offers products with these and other features from several manufacturers. Here is a representative checklist:

• A sweep mode is extremely important. Sweep provides a slight ± variation in ultrasonic frequency to provide more uniform cleaning to highly finished delicate products such as jewelry, watch parts and gemstones. Select a model with permanent sweep. (The alternative to sweep is "normal" which means fixed frequency. This has value in certain applications but not in cleaning jewelry.)
• Timers let you set the length of the recommended cleaning cycle length (often suggested by cleaning solution manufacturers and your personal user experience). When cleaning begins start the timer and attend to other matters. The unit will turn off at the end of the cycle. Time cycles depend on models.
• Temperature controls– thermostats – let you set the recommended cleaning temperature, also suggested by solution manufacturers (and your experience). Some equipment will automatically start the ultrasonic cleaning cycle when the set temperature is reached.

How Do Ultrasonic Cleaners Work?

A simple way that ultrasonic cleaners work is likening them to an automatic dishwasher, but with some added refinements. An automatic dishwasher, much the same as an ultrasonic cleaner, combines water and a detergent to remove grease, grime and other contaminants from objects being cleaned.

Applications for ultrasonic cleaners include cleaning precision optics and laboratory glassware. Instead of cleaning pots and pans and bowls, ultrasonic cleaners most often are used to clean various other metal and plastic products difficult or impossible to clean by other methods.

Components of an Ultrasonic Cleaner

• Tanks to hold the cleaning solution. Tanks should be of stainless steel; their volume depends on the size of objects being cleaned

• Ultrasonic transducers that create the cavitation and that are bonded to the bottom of the tank

• A generator to power the transducers

• Controls that range from a simple on-off switch to sophisticated microprocessors that govern cleaning time, sweep, pulse, degassing, temperature, ultrasonic frequency , ultrasonic power, auto safety shutoffs and other refinements. More on these below.

What Do Ultrasonic Transducers Do?

There are two basic types of transducers; piezoelectric (a.k.a. electrostrictive) or magnetostrictive, but their function is the same. They are excited by electric current provided by the ultrasonic cleaner's generator to vibrate at ultrasonic frequencies that cause the bottom (and sides as the case can also be) of the tank to vibrate and thus serve as a membrane. This vibration forms the vacuum bubbles that implode, (not explode) on contact with items in the ultrasonic cleaner tank thereby blasting loose and carrying away contaminants. There are also immersible transducers. Ultrasonic frequency is an important part of how ultrasonic cleaners work and is discussed next.

How to Choose an Ultrasonic Cleaner Frequency

Ultrasonic is typically defined as sound above the human range of hearing. Low frequencies such as 25,000 cycles per second or 25 kHz produce relatively large bubbles that implode more violently than those created at higher frequencies such as 37, 80 or 130 kHz that produce progressively gentle cleaning action. As an example, the radius of a cavitation bubble produced at 37 kHz is approximately 88 microns. At 80 kHz it is 41 microns.

As a bit of digression, the implosion of cavitation bubbles produce shock waves radiating from the site of the collapse and create temperatures in excess of 10,000°F and pressures in excess of 10,000 psi at the implosion site. Yet the process is so fast that there is little heat buildup and no damage to parts being cleaned. That said, one should never reach into an operating ultrasonic cleaner to check, reposition or remove parts for examination.

Removing gross contaminants from robust parts such as fabricated or cast metals requires lower frequency cleaners. Softer metals, plastics, and products with polished surfaces should be cleaned at higher frequencies. In addition to protecting polished surfaces smaller bubbles are better able to penetrate tight areas such as seams, crevices and blind holes.

Our point is that purchasing decisions for an ultrasonic cleaner should be made on more than price.
