1、product detail drawing
The function of ultrasonic generator is to convert the mains electricity into the high frequency alternating current signal matched with the ultrasonic transducer, and drive the ultrasonic transducer to work. High power ultrasonic power supply generally adopts the circuit form of switching power supply from the aspect of conversion efficiency. Ultrasonic power supply is divided into excitation and its excitation power supply, the excitation power supply is called ultrasonic analog power supply, it is called the excitation power supply ultrasonic generator.
Ultrasonic generator using the world's leading other excitation vibration circuit structure, than the self-excitation vibration circuit structure in the output power of more than 10%. The form of ultrasonic amplifier circuit adopts linear amplifier circuit and switching power supply circuit.
Advantages of switching power supply circuit: high conversion efficiency, so high power ultrasonic power supply in this form.
Advantages of linear power supply circuit: it does not strictly require circuit matching, allowing continuous and rapid changes in operating frequency.
The ultrasonic generator produces a signal at a particular frequency, either a sinusoidal signal or an impulse signal, which is the frequency at which the transducer operates.
Ultrasonic equipment generally uses the ultrasonic frequency of 20kHz, 25kHz, 28kHz, 33kHz, 40kHz, 60kHz, 80kHz, 100kHz or above has not been used in large quantities.
Advantages:
1. Ultrasonic generator can monitor the working frequency and power of high-power ultrasonic system.
2, according to the user's different requirements, real-time adjustment of various parameters, such as power, amplitude, running time, etc.
3, frequency fine-tuning: adjust the frequency to make the ultrasonic transducer always work in the best state, the maximum efficiency, adjust the range of 2%.
4. Automatic frequency tracking: once the equipment completes the initial setting, it can operate continuously without adjusting the generator.
5. Amplitude control: when the load of the transducer changes in the working process, the driving characteristics can be automatically adjusted to ensure the stable amplitude of the tool head.
6. System protection: when the system works in an inappropriate operating environment, the generator will stop working and alarm display to protect the equipment from damage.
7, amplitude adjustment: amplitude can be increased or decreased instantly in the process of work, amplitude setting range: 0%~100%.
8. Automatic frequency search: it can automatically determine the working frequency of the tool head and store it.
