Working principle of ultrasonic power supply
Ultrasonic power supply, also known as ultrasonic generator, is a device used to generate and provide ultrasonic energy to ultrasonic transducer. Its purpose is to convert our city power (220 V or 380 V, 50 Hz or 60 Hz) into a high frequency AC signal that can match with the ultrasonic transducer. The signal can be a sine signal or a pulse signal.
The ultrasonic screening system consists of power supply, connecting cable, transducer and resonator. The high frequency electricity generated by the power supply of ultrasonic vibration screen is converted into longitudinal oscillation wave of high frequency sinusoidal form through transducer. These oscillation waves are transmitted to the resonator to make the resonator resonate, and then the vibration is transmitted to the screen surface uniformly by the resonator. The material on the screen is subject to low-frequency three-dimensional vibration, and at the same time, the ultrasonic vibration is superimposed on it, which can not only prevent the mesh from blocking, but also improve the screening yield and accuracy.
