Ultrasonic power is often referred to as an ultrasonic source, an ultrasonic generator. Its function is to convert electrical energy into a high frequency alternating current signal that matches the ultrasonic transducer. From the form of the amplifying circuit, a linear amplifying circuit and a switching power supply circuit can be used, and the high-power ultrasonic power source generally adopts a circuit form of a switching power supply in terms of conversion efficiency. Linear power supplies also have their own range of applications. It has the advantage of not requiring strict circuit matching and allowing continuous and rapid changes in operating frequency. From the current situation in the ultrasound industry, ultrasound is mainly divided into self-excited and its exciting power supply.

The principle of the ultrasonic power supply is to first generate a signal of a specific frequency by a signal generator. This signal can be a sinusoidal signal or a pulse signal. This specific frequency is the frequency of the transducer, and is generally applied to the ultrasonic frequency in the ultrasonic device. It is 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz; 100KHz or more is not yet used in large quantities. However, with the continuous development of precision cleaning. I believe that the use of the face will gradually expand.

The ultrasonic generator generates a signal of specific frequency, which may be a sinusoidal signal or a pulsed signal. This specific frequency is the frequency at which the transducer operates.

Ultrasonic equipment generally uses ultrasonic waves of 20 kHz, 25 kHz, 28 kHz, 33 kHz, 40 kHz, 60 kHz, 80 kHz, 100 kHz or more, and has not been used in large quantities.

Ultrasonic power matching circuit includes output transformer, inductor and transducer. This circuit isolates the high-voltage signal after power amplification with the output transformer, and then excites the series (parallel) resonant circuit composed of the resonant inductor and the ultrasonic transducer to make it resonate, convert the electrical energy into mechanical energy most effectively, and realize the ultrasonic Purpose of cleaning.
It is suitable for cleaning electroplating parts before plating, stainless steel hardware parts dewaxing, degreasing cleaning, metal products, copper and aluminum parts, mechanical parts, zinc alloy parts, clock parts, glasses, jewelry, glassware, etc., almost all hard plastics, Cleaning of oil, polishing paste, dust and other attachments remaining in the machining process of metal and hardware parts.
