What is an ultrasonic vibrator
Ultrasonic vibrating rod is also called ultrasonic vibrating rod. Compared with traditional ultrasonic vibrating plate, it has the characteristics of wider application range and longer service life. In industrial applications, the use of ultrasonic vibrating rods for cleaning, extraction, chemical reactions, antiscaling, water treatment, etc. is a very mature and widely used technology.
The ultrasonic vibrating rod is an alternating period of positive and negative pressure during the transmission process of the ultrasonic wave. At the positive phase, the molecules of the medium are squeezed to increase the original density of the medium. At the negative phase, the molecules of the medium are sparse and discrete, and the medium density Decrease. The ultrasonic vibrating rod can generate ultrasonic waves uniformly around 360 °, and the energy output is not affected by load changes such as liquid level and temperature difference. The ultrasonic vibrating rod generally includes high-power ultrasonic transducers, horns, and tool heads (transmitting heads). ), Which is used to generate ultrasonic vibration and emit this vibration energy into the liquid. The transducer converts the input electrical energy into mechanical energy, that is, ultrasound. Its manifestation is that the transducer moves back and forth in the longitudinal direction, and the amplitude is generally a few microns. Such amplitude power density is insufficient and cannot be used directly. The horns amplify the amplitude according to the design requirements, isolate the reaction solution and the transducer, and also play a role in fixing the entire ultrasonic vibration system. The tool head is connected to the horn, which transmits the ultrasonic energy vibration to the tool head, and the tool head emits the ultrasonic energy into the chemical reaction liquid.
