Ultrasonic generator and transducer resonance point matching
The ultrasonic generator and transducer must find the resonance point. The actual frequency of the ultrasonic transducer is not the factory configuration frequency. It is related to the pasting process, the precision of the pasting, the amount of glue, the verticality of the fastening screw, and the water level. The water temperature is related to the additives of the cleaning medium and so on.
The ultrasonic generator and transducer need to find the resonance point. The actual frequency of the ultrasonic transducer is not the factory configuration frequency. It is related to the pasting process, the precision of the pasting, the amount of glue, the verticality of the fastening screw, and the water level. The water temperature is related to the additives of the cleaning medium and so on. When each ultrasonic generator is in use, it should be adjusted and adjusted according to the frequency of the ultrasonic generator. When adjusting the frequency, one thing needs to be paid attention to. That is to adjust the inductance of the ultrasonic generator first, according to the output ultrasonic power of the generator. Adjust the inductance of the size, current size, sound, cleaning effect, etc. to match, find the resonance point, and fine-tune the frequency to achieve the ultrasonic effect. Of course, the adjusted inductance is related to the power of the ultrasonic generator. For example, if the power is 5a, the adjusted current is about 4.5a. After fine-tuning the frequency, the ultrasonic current will reach the output effect. The advantages of this are: it will not cause the transducer to heat up due to the resonant point mismatch, and the temperature will be too high, which will easily burn out; it will not burn the generator power supply due to the mismatch between the generator and the transducer; at the same time, it can Ensure the effect.
