25/45khz 100W Dual Frequency Ultrasonic Piezo Ceramic Transducer Ultrasonic Therapy Transducer For Cleaning Machine

Ultrasonic transducer are mainly used in ultrasonic cleaning machines and laboratories. Three frequency bands, four frequency bands and five frequency bands can be selected from 25khz-135khz. The direction of clarity strength covers rough cleaning, fine cleaning, etc. Compared with single frequency transducers, more cleaning schemes are provided, but the cost will increase accordingly.

The effectiveness of ultrasonic cleaning machines varies between high and low frequencies in cleaning. When the ultrasonic frequency is high, the cavitation intensity and density generated in the liquid are low, and high-frequency ultrasound can penetrate grooves, fine seams, and deep holes. However, when the ultrasonic frequency is low, the cavitation intensity is high, the number of bubbles is small, and the cleaning effect on the surface of objects is large. The multi frequency ultrasonic cleaning machine consists of an ultrasonic generator and a ultrasonic transducer, a multi frequency ultrasonic transducer, and a separate transmission power supply. The ultrasonic generator not only generates a reference voltage, but also generates a continuous asymmetric triangular wave with a certain amplitude, while providing a synchronous square wave pulse signal for the T-shaped trigger to work. The circuit form of the ultrasonic cleaning machine is simple, easy to convert, and reliable in operation. The generator circuit of a multi frequency ultrasonic cleaning machine includes a control circuit, an oscillation circuit, and a power output circuit. The multi frequency ultrasonic cleaning machine is based on the single frequency ultrasonic cleaning machine, changing the size of the matching power inductance changes the oscillation frequency, realizing the multi frequency function, making the ultrasonic cleaning machine share the control circuit and ultrasonic transducer, simplifying the structure of the ultrasonic cleaning machine, and reducing the cost. That is, two or more ultrasonic transducer with different frequencies are installed in one cleaning cylinder, and ultrasonic transducer with different frequencies are driven by multiple generators. At the same time, there are multiple frequencies of ultrasonic waves in the cylinder, which also overcomes the problem of uneven cleaning caused by a single frequency cleaning standing wave field.
