The working principle of ultrasonic transducer—Core Part of Ultrasonic Cleaning Systemby Farooq Gill ---
Beijing - The most important part of the ultrasonic cleaning system should be the ultrasonic transducer. According to the engineer from Beijing Yongda Ultrasonic which is the best China manufacturer for this device, there are two existing sorts of transducer in today’s market. The first one is the magnetic transducer which is made of nickel or the nickel alloy. The second one is the piezoelectric transducer which is made of lead Zirconate Titanate or other ceramic materials. For the second one, it applies the principle of piezoelectric effect which the piezoelectric material will be deformed if people put it into the changing electric field. Relatively speaking, the first magnetic transducer will occur related deformation in the magnetic field.
Regardless of the type of piezo transducer , the intensity of cavitation effect should be typically the most basic factor for the performance of the ultrasonic cleaning system. The ultrasonic is familiar with the sound waves, which are series of pressure points or an alternating compression and expansion waves. If the acoustic energy is strong enough, the liquid will be pushed in the expansion phase of the wave, thereby, it will generate bubbles. Then, in the compression phase of the sound wave, these bubbles will burst in liquid, which will produce very effective impacting that is particularly suitable for cleaning object. So, the quality of the ultrasonic transducer for cleaning system could totally determine the effect of the cleaning effect.
Theoretically, the bursting of the cavitation bubble will produce more than 10,000 psi of pressure and 11,000 centigrade temperatures. On the other hand, the impacting wave produced by the bursting will quickly radiate outward. However, the energy releasing of the single cavitation bubble is small. If there are several million cavitation bubbles produce bursting during per second simultaneously, the cumulative effect of it will be very strong and the powerful impacting force will cause into the spalling effect of dirt surface. This is the characteristic of the ultrasonic cleaning.
If the piezoelectric ceramic owns high quality and it could produce the ultrasonic energy is large enough, the cavitation phenomenon will generate around every corner into cleaning fluid so the ultrasonic cleaning can effectively clean the dirty in any cracks and holes. In addition to amazing cleaning effect, the cavitation caused by the transducer could also promote and accelerates the dissolution reaction of the surface film.
The effect of ultrasonic cleaning is mainly determined by the high quality ultrasonic cleaning transducer. So, if people who use ultrasonic cleaning machine want to get good cleaning effect, you must purchaser first class transducer.
