What Are The Main Mechanical Effects Of Ultrasonic Embossing Machine?

In the specific application, ultrasonic emboding machine mainly has mechanical effect (such as particle vibration displacement, speed, acceleration, sound pressure and other mechanical amount of sound transmission medium), thermal effect (part of the energy of sound wave in the propagation process is absorbed by the medium for heat energy) and cavity effect. In the past, complex mechanical parts needed to be cleaned manually for a long time in a dirty environment, requiring a lot of manual labor. After the application of ultrasonic cleaning machine, not only improve the working environment, eliminate the harm of manual cleaning to the workpiece, but also reduce the labor intensity. On the basis of greatly improving the cleaning precision, the cleaning time is shortened to one fourth of the original.

Of course, not all the gas cores in liquid management can develop a cavity effect. Only when the applied ultrasonic frequency is the same as the natural frequency of the gas core, the cavity effect can continue to occur. It is also influenced by other social factors such as the intensity of sound waves, temperature changes in liquid media, and vapor pressure in different media. The ultrasonic frequency of inducing cavity effect is suitable for 20kHz ~ 80kHz. Too high frequency is not easy to control the cavity effect, even if it is produced, it needs to provide a lot of energy, and most of the energy in China is converted into heat energy, so that the ambient temperature of the medium has not been significantly improved.

The application of low intensity ultrasonic wave will not cause any change of medium state, and only the application of high intensity ultrasonic wave can produce strong impact on medium and cause cavity effect. For most chemical reactions, the reaction rate increases with increasing "sound intensity". However, the influence of ultrasonic intensity is greatly affected by the temperature of the medium.
