Replacement Telsonic 20khz Ultrasonic Plastic Welding Transducer with 2000w Power
Description:
Ultrasonic transducer is an energy conversion device that converts high-frequency electrical energy into mechanical energy. In fact, it is a piezoelectric ceramic whose frequency is the same as its resonant frequency. It uses the piezoelectric effect of the material to convert electrical energy into mechanical vibration. Under normal circumstances, ultrasonic waves are first generated by an ultrasonic generator, converted into mechanical vibration by an ultrasonic transducer, and ultrasonic waves are generated by an ultrasonic derivation device and an ultrasonic receiving device.

The physical definition of a wave is that the transmission of vibration in an object forms a wave. There must be two conditions for the formation of such waves: one is the source of vibration and the other is the propagation medium. The classification of waves generally has the following types: First, classification according to the direction of vibration and the direction of propagation. When the direction of vibration is perpendicular to the direction of propagation, it is called a transverse wave. When the direction of vibration coincides with the direction of propagation, it is called a longitudinal wave. Second, according to the frequency classification, we know that the human ear sensitive hearing range is 20HZ-20000HZ, so the wave within this range is called sound wave. Waves below this range are called infrasound waves, and waves above this range are called ultrasonic waves.
Transducer working mode
Due to different processing methods and requirements, the working mode of the transducer can be roughly divided into continuous work (lace machine, CD set machine, zipper machine, metal welding, etc.) and pulse type work (such as plastic welding machine). Different working methods The requirements for the transducer are different. In general, continuous operation has almost no pause time, but the operating current is not very large, the pulse operation is intermittent, there is a pause, but the instantaneous current is very large. On average, the power of both states is large.
