What are the components of ultrasonic dispersion equipment
1. Ultrasonic vibration source (driving power): convert 50-60Hz commercial power into high-power high-frequency (15khz-100khz) power supply for transducer.
2. Transducer: convert high frequency electrical energy into mechanical vibration energy.
3. Horn: connect and fix the transducer and tool head, amplify the amplitude of transducer and send it to tool head.
4. Tool head (lead-in rod): it transmits mechanical energy and pressure to the working object, and also has the function of amplitude amplification.
5. Connecting bolt: connect the above components tightly.
First of all, we know that the range of ultrasonic high power is between 15k-70khz. The higher the ultrasonic frequency is, the more times of vibration is. If the amplitude is the same, the effect of high frequency is better than low frequency
However, people can't hear above 20kHz, so we suggest that the higher the ultrasonic frequency is, the smaller the transducer will be. There are piezoelectric ceramic pieces on the transducer (the number and diameter of piezoelectric ceramic pieces are different). Piezoelectric ceramics can be used as capacitors to store energy and radiate energy. However, the higher the frequency, the smaller the size of piezoelectric ceramics. The conclusion is that the higher the frequency, the smaller the power of ultrasonic. For example, 3000W can be achieved at 20K, 800W can be achieved at 30kHz,
So when we choose the ultrasonic frequency, if we consider industrialization, we can choose 20kHz
