The ultrasonic generator is an important part of the high-power ultrasonic system. It can also be called an electronic box, ultrasonic drive power supply, and ultrasonic controller. It can be used for mask welding and plastic welding. It can also be installed on the production line to realize automated operation. Then, let's learn about the precautions for using the ultrasonic generator.
Precautions for using the ultrasonic generator:
1. When the ultrasonic emission surface of the diaphragm is submerged by 10mm, the ultrasonic generator power supply can be turned on. If there is no cleaning liquid in the cleaning tank, start the ultrasonic source to avoid damaging the transducer.
2. Prevent hard objects from impacting and vibrating the ultrasonic diaphragm, and do not place the workpiece directly on the diaphragm surface.
3. Do not make the cleaning liquid level higher than the diaphragm outlet during use. It is forbidden to wash with clean water to prevent water from overflowing from the outlet to the vibration plate or electrical box and causing malfunctions.
4. The diaphragm must not be immersed in strong acid or strong alkali liquid for a long time.
5. When changing the cleaning liquid, the temperature difference between the two should not be too large to prevent the vibration plate from deforming due to sudden cooling and rapid heat, causing the vibrator to fall off.
6. Too much dirt on the surface of the ultrasonic diaphragm will weaken the ultrasonic vibration force and reduce the cleaning effect. It should be cleaned in time.
7. When cleaning the dirt on the surface of the vibration plate, do not use a tool to cut or strongly vibrate the surface of the vibration plate.
8. When the power supply voltage changes beyond the allowable range of the machine, it should be suspended.
Advantages of ultrasonic generator:
1. The ultrasonic generator can monitor the working frequency and power of the high-power ultrasonic system.
2. Various parameters such as power, amplitude, and running time can be adjusted in real time according to user requirements.
Frequency fine-tuning: Adjust the frequency so that the ultrasonic transducer always works in a good state and improves efficiency. The adjustment range is 2%.
Automatic tracking: After the initial setting of the machine is completed, it can work continuously without adjusting the generator.
Amplitude control: When the load changes during the operation of the transducer, the drive characteristics can be automatically adjusted to ensure the stable amplitude of the cutter head.
System protection: If the system is running in an incorrect operating environment, the generator will stop running, issue a warning and protect the equipment from damage.
Amplitude adjustment: The amplitude can be increased or decreased instantly during operation.
Automatic tracking: The working frequency of the cutter head can be automatically measured and saved.
Ultrasonic power supplies are divided into self-excited and externally excited types. The self-excited power supply is called an ultrasonic analog power supply, and the externally excited power supply is called an ultrasonic generator. The ultrasonic generator adopts an externally excited oscillation circuit structure, and the output is increased by more than 10% compared with the self-excited oscillation circuit structure. The ultrasonic amplifier circuit adopts a linear amplifier circuit and a switching power supply circuit.
The above is the precautions for using the ultrasonic generator. If you need to know more, you can contact us at any time.
