What is the function of the frequency sweep function on the ultrasonic generator
Ultrasonic generators are usually called ultrasonic electric boxes, ultrasonic generators, and ultrasonic power sources. Its function is to convert our mains electricity (220V or 380V, 50 or 60Hz) into a high-frequency alternating current signal that matches the ultrasonic transducer. From the form of amplifying circuit, linear amplifying circuit and switching power supply circuit can be used, and high-power ultrasonic power supply generally adopts the circuit form of switching power supply from the aspect of conversion efficiency. The linear power supply also has its unique application range. Its advantage is that it does not require strict circuit matching and allows the operating frequency to change continuously and rapidly. Judging from the current situation in the ultrasound industry, the ultrasonic generator adopts a separately excited oscillation circuit structure, which increases the output power by more than 10% compared with the previous self-excited oscillation circuit structure. The electrical performance meets the technical standards provided by Party A. The ultrasonic generator The working voltage of the device is AC220±; 10V. The ultrasonic generator has protection measures such as overvoltage, overcurrent, and output short circuit.
The ultrasonic generator has the function of fine-tuning the frequency, the adjustment range is 2%, under different working conditions, slightly adjusting the transducer to always work in the state, the energy conversion efficiency reaches a large, and the effect can be achieved under different working conditions.
Ultrasonic generator has a frequency sweeping function. During the cleaning process, the ultrasonic frequency is swept back and forth within a reasonable range to drive the cleaning liquid to form a fine backflow, so that the dirt on the workpiece is quickly removed from the surface of the workpiece while being ultrasonically stripped, improving the cleaning efficiency.
The ultrasonic generator has a power adjustment function, and the output power can be adjusted continuously from 10% to 100% to meet the requirements of various cleaning objects.
