35Khz 300w Ultrasonic High Power Transducer For Spot Plastic Welding Series

Description:

Ultrasonic waves convert high frequency electrical energy into mechanical vibration through a transducer. The characteristics of the transducer depend on the material selection and manufacturing process. The performance and service life of the ultrasonic transducer of the same size are very different. Commonly used high-power ultrasonic transducers are used in ultrasonic plastic welding machines, ultrasonic metal welding machines, various hand-held ultrasonic tools, ultrasonic emulsifier homogenizers, atomizers, ultrasonic engraving machines, etc.
Commonly used 15KHz 20KHz 28KHz 35KHz 40KHz 55KHz 70KHz and other products We can also design and manufacture non-standard ultrasonic transducers according to customer's special requirements to meet various needs.

Why is the wavelength of the sound wave measured at the resonant state of the transducer?

Resonance is conditional. For tube resonance, it is generally 1/4 wavelength resonance. The calculation formula is: 1/4 wavelength of sound wave = length of tube + effective length of tube diameter conversion; when resonance occurs, it can be used Calculate the wavelength of the tube and the diameter of the tube, and calculate the speed of sound (frequency multiplied by wavelength = speed of sound); if the wavelength is not calculated without resonance, the speed of sound cannot be calculated; whether the measurement system is in resonance or not is whether the sound energy is measured. At the maximum, the method is to use frequency scanning. When the sound energy output is maximum, the output frequency is recorded and then calculated. For the resonance measurement of the tube resonance, there is a defect, that is, the effective length of the diameter conversion; usually, the standing wave method for measuring the sound velocity is Measure adjacent peaks or nodes (half wavelength) of standing waves.
