Application of ultrasonic vibrator in cleaning
Due to its unique tubular design, the ultrasonic vibrator is particularly suitable for all types of pipe cleaning, the principle is to convert electrical energy into ultrasonic energy, and in accordance with its own laws to Limescale, water, pipe wall, so it gets a lot of energy. The vibration wave produced by the ultrasonic wave makes the scale, water and the inner wall of the pipe resonate. Because of the different vibration frequency of the scale, water and the inner wall of the pipe, the water molecules in the pipe collide violently, it can make the fouling layer on the heat transfer surface brittle, peeling, falling off, crushing, and discharge with the sewage of the equipment, thus realizing the thorough cleaning of the inner wall of the pipeline by the ultrasonic vibrator. In addition, the ultrasonic vibrator can also be used for the cleaning of the tank body, can be freely placed in any position of the cleaning tank, use is very flexible and convenient, and occupies a small volume space, cleaning does not leave a dead corner.

Application of ultrasonic vibrator in extraction of traditional Chinese medicine
The effective components of traditional Chinese medicine can be extracted by ultrasonic vibrator. Firstly, an extraction solvent is added to the container, and the Chinese medicinal herbs are crushed or cut into granules according to the need and put into the extraction solvent, on the one hand, ultrasonic wave can effectively break the cell wall of medicinal materials, and on the other hand, it can also produce cavitation effect and mechanical action in extracting solvent, on the other hand, it can speed up the molecular movement of the extraction solvent, and make the extraction solvent and the active components in the medicinal materials contact quickly, dissolve and mix with each other./n/nThe optimum temperature for extracting medicinal materials by ultrasonic vibrating rod is 40 ~ 60 °C, so it is not necessary to equip with boiler to provide steam heating, which is beneficial to saving energy and improving environmental pollution. What's more, it can protect the active ingredients in the medicinal materials which are unstable in heat, easy to hydrolyze or oxidize. The best effect can be obtained when the ultrasonic vibrator is operated for about 30 minutes, and the extraction efficiency is greatly improved compared with the traditional process, and it is not limited by the properties and molecular weight of the Chinese medicinal materials, it is suitable for the extraction of most kinds of Chinese medicinal materials and all kinds of components (including liquid-liquid extraction and solid-liquid extraction) . Therefore, the use of ultrasonic vibrator extraction of traditional Chinese medicine has been more and more widely used by pharmaceutical companies.

Application of ultrasonic vibrator in accelerating chemical reaction
The front end of the emitting head of the ultrasonic vibrator tool is attached to the external wall of the kettle body or extends into the kettle cavity of the kettle body. The Ultrasonic transducer can send ultrasonic waves to the chemical reactants in the kettle cavity, because of the"Cavitation" effect of ultrasonic wave, the treated liquid can change the activity of the reaction system, destroy the solvent structure of the chemical reactants in the tank cavity, and produce high temperature and high pressure which can trigger the chemical reaction, the formation of a local high-energy center, promoting the smooth chemical reaction, which is the use of ultrasonic vibration rod for catalytic chemical reaction of the main factors./n/nThe secondary effects of ultrasonic wave, such as mechanical vibration, emulsification, diffusion and crushing, are favorable to the full mixing of reactants in all directions, it can make the material make violent forced motion, accelerate the transfer and diffusion of the material, and can replace the traditional mechanical agitation. Of course, in practical application with the use of electric agitator, accelerated reaction effect is better.
