The principle of Ultrasonic Cleaner
1. What's Ultrasonic?
Generally speaking, ultrasonic refers to the sound wave with frequency larger than 20 KHz which is
beyond the upper limit of human ear.Ultrasonic is characterized by strong beam property and being easy
to collect energy through focusing. Ultrasonic is also an energy form, and when the intensity exceeds a
certain value, it can affect, change and damage the state, character and structure of matters through its interaction with sound bearing medium (commonly called ultrasonic power).
2. Ultrasonic Cleaner's Formation and Working Principle
A. Formation
Ultrasonic cleaner mainly consists of ultrasonic generator,circuit controller,transducer and cleaning tank.
B. Working Principle
Ultrasonic generator output oscillation power signal of ultrasonic frequency which is then through changed into mechanical oscillation with high frequency by transducer; next, the oscillation is introduced
into cleaning liquid, causing the cleaning liquid to produce ultrasonic cavitation effect which can generate
tens of thousands of tiny bubbles which are formed at the negative pressure region and fast closed in the positive pressure region;the closed bubbles form ten thousands of instant high pressure of small pressures,
and the continuously generated instant high pressure is like a sequence of small 'explosion' to impact the clearances on the surface of object, causing various pollutant sticking to the surface of object to flake off
so as to realize the purpose of cleaning.
