The audio frequency electrical signal higher than 20kHz generated by the ultrasonic generator is converted into mechanical oscillation of the same frequency through the piezoelectric inverse effect of the transducer, and radiated in the cleaning solution in the form of ultrasonic longitudinal wave. Due to the alternating action of positive pressure and negative pressure of ultrasonic longitudinal wave propagation, countless tiny bubbles with more than 1000 atmospheres are produced and burst at any time, forming a fine local high-pressure bombardment on the surface of the cleaned object, which makes the dirt on the surface and in the gap peel off rapidly. This is the unique "cavitation effect" of ultrasonic cleaning. Using the latest external excitation control circuit, the ultrasonic density is greatly improved, the cleaning work is more detailed and the cleanliness is higher. The ultrasonic power generator has the function of frequency sweeping. By sweeping the ultrasonic frequency back and forth within a reasonable range during the cleaning process, it drives the cleaning fluid to form a slight reflux, so that the dirt of the workpiece can be quickly taken away from the surface of the workpiece while being stripped by ultrasonic, so as to improve the cleaning efficiency. The original imported high-power tube drive, with up to 95% power factor, ensures strong output power. The dirt with strong adhesion can also be removed quickly. In the working state, the frequency tracking is realized in real time. Ensure that the generator can keep automatic frequency tracking at any time when the frequency of the transducer changes when the water temperature, the number of workpieces and cleaning agent change, so as to achieve the best working state matching the frequency of the transducer.
