Ultrasonic vibration rods, also known as ultrasonic vibration rods, have a wider range of applications and longer service life compared to traditional ultrasonic vibration plates. In industrial applications, the use of ultrasonic vibration rods for cleaning, extraction, chemical reactions, scale prevention, water treatment, ฯลฯ. is a very mature and widely used technology.

The ultrasonic vibrating rod utilizes the alternating period of positive and negative pressure during the transmission process of ultrasound, which compresses the medium molecules during the positive phase, increasing the original density of the medium; When the phase is negative, the molecules in the medium are sparse and discrete, resulting in a decrease in the density of the medium. Ultrasonic vibration rods can generate ultrasonic waves uniformly around 360 °, and the output of energy is not affected by load changes such as liquid level and temperature difference. Ultrasonic vibration rods generally include high-power ultrasonic transducers, amplitude transformers, and tool heads (emission heads), which are used to generate ultrasonic vibration and emit this vibration energy into the liquid. The transducer converts the input electrical energy into mechanical energy, which is ultrasound. Its manifestation is that the transducer moves back and forth in the longitudinal direction, with an amplitude typically of a few micrometers. This amplitude power density is not sufficient and cannot be directly used. The amplitude transformer amplifies the amplitude according to the design requirements, isolates the reaction solution and transducer, and also serves to fix the entire ultrasonic vibration system. The tool head is connected to the amplitude converter, which transmits ultrasonic energy vibration to the tool head, which then emits the ultrasonic energy into the chemical reaction liquid
