Design of Ultrasonic Sealer Based on Embedded Microcontroller
Ultrasonic scale removal is a new scale prevention device,which adopts ultrasonic oscillator to carry out online scale prevention and scale removal of pipelines water scale. This paper adopts magnetostrictive combined with embedded controller,controlling PWM generator SG3525 to generate ultrasonic signal,whose two complementary frequency and duty cycle are adjustable,furthermore,controlling large power Insulated Gate Bipolar Transistor (IGBT) s on-off to control magnetostrictive oscillator,so that it can generate ultrasonic oscillation. On the base of analyzing ultrasonic oscillation systems working principle,design scale removal devices hardware circuit,and finish corresponding software program. simultaneously,establish corresponding experiment platform,make experiment analysis to ultrasonic scale removals performance,finally,carry through site operation,and thus validate scale removal devices validity. The result indicates that scale removal device meets design performances requirements.
