60W Ultrasonic Transducer 40Khz Two Frequency For Car Engine/Block/Plastic Parts Ultrasound Cleaner Machine

Ultrasonic vibrator, also known as ultrasonic vibrator, refers to the overall structure of the transducer connected to the amplitude converter in the industry.

The ultrasonic vibrator uses the Piezoelectricity of piezoelectric ceramics to realize the mutual conversion of electrical energy and mechanical energy (acoustic vibration), and uses the front and rear radiation cover blocks matched with acoustic impedance to amplify the device. The frequency is fixed during production. You can customize transducers with different frequencies according to customer needs. The produced transducer vibrator can only be fixed at this frequency. In fact, the ultrasonic cavitation threshold is closely related to frequency. The higher the frequency, the higher the cavitation threshold. The lower the frequency, the lower the cavitation threshold, and the easier it is to generate cavitation.

At low frequencies, the time interval between compression and sparsity of liquids is longer. Enabling bubbles to grow to a larger size, enhancing cavitation strength, and facilitating cleaning effects. So low-frequency ultrasonic cleaning is generally used on the surface of large components or when the adhesion between dirt and workpiece surface is high. But it is easy to damage and corrode the surface of the workpiece. Therefore, parts with high surface requirements for the workpiece are not suitable for selecting lower frequencies. Moreover, the frequency is low and the generated noise is correspondingly high. High frequency ultrasound has strong penetration power, and it is recommended to clean components with high surface smoothness requirements or complex surfaces with many blind holes.

On the one hand, the noise of high-frequency ultrasound is also relatively low, making it suitable for cleaning some precision parts, such as electronic parts, small bearing processing, magnetic materials, etc. For some special workpieces such as integrated circuit chips and silicon wafers, it is advisable to choose higher frequency ultrasound for cleaning. For some large workpieces such as car engines, valves, etc., low-frequency ultrasound should be chosen for cleaning.

On the other hand, considering the effectiveness and economy of ultrasonic cleaning, the frequency is generally selected between 20~130KHz. The specific frequency selection should be determined through corresponding experiments. In summary, the frequency of the ultrasonic oscillator is fixed, so during production, there will be continuous testing procedures to determine whether the frequency is qualified, and production will be strictly carried out according to requirements.
