To adjust the current peak of the ultrasonic generator to the highest peak, you can follow the steps below:
Understand the equipment parameters:
Consult the technical manual or instructions of the ultrasonic generator to understand the key information such as the maximum current peak of the equipment, the power supply voltage range, and the resonant circuit parameters.
Prepare tools:
Prepare the required tools, such as voltmeter, current clamp meter, screwdriver, etc.
Check the power supply:
Use a voltmeter to detect the power supply voltage and ensure that it is within the rated voltage range of the ultrasonic generator. If the power supply voltage is too low or too high, the current peak may not reach the highest.
Adjust the power supply voltage:
If the power supply voltage is not within the optimal range, adjust the power supply voltage appropriately to make it close to the rated voltage of the ultrasonic generator. This helps to increase the current peak.
Change the resonant circuit parameters:
The resonant circuit has a great influence on the output power and current peak of the ultrasonic generator. According to the technical manual of the ultrasonic generator, gradually adjust the inductor, capacitor and other components in the resonant circuit to achieve the best matching state. Specific steps may include:
Loosen the fixing screws of the inductor or capacitor in the resonant circuit.
Gradually increase or decrease the value of the inductor or capacitor while observing the current value displayed on the embedded ammeter.
When the current value approaches or reaches the highest peak, stop adjusting and tighten the fixing screws of the inductor or capacitor.
Adjust the amplitude modulation signal:
If the ultrasonic generator supports amplitude modulation, the current peak can be changed by adjusting the amplitude and frequency of the amplitude modulation signal. Specific methods include:
Adjust the amplitude control knob of the amplitude modulator to increase the amplitude of the output signal, thereby increasing the current peak.
Adjust the frequency control knob of the amplitude modulator to find the best frequency that matches the ultrasonic generator to increase the current peak.
Check the coupler status:
The ultrasonic generator and the transducer are connected through a coupler. If the coupler is in poor condition, it may cause the current peak to decrease. Check the condition of the coupler regularly to ensure that it is well connected and replace damaged coupler parts.
Check the output signal frequency:
The output frequency of the ultrasonic generator has a great influence on its output power and current peak. According to the technical manual of the ultrasonic generator, gradually adjust the output frequency to find the frequency point that makes the current peak reach the highest.
Step-by-step debugging:
During the debugging process, gradually increase or decrease the value of each parameter, while observing the current value displayed on the embedded current meter. Avoid adjusting too much at one time to avoid damaging the equipment or affecting the debugging effect.
Testing and verification:
After the debugging is completed, use an ultrasonic sensor or other equipment to receive the ultrasonic signal output by the generator to ensure that the signal can be received normally and the current peak has reached the maximum.
Please note that during the debugging process, be sure to follow the guidance of the technical manual and instructions of the ultrasonic generator and make adjustments according to the actual situation of the equipment. If you are not sure how to operate, it is recommended to consult professional technicians or equipment manufacturers for advice.
