35Khz Ultrasonic Analog Power Supply for Sewing Machine with External Control

Description:

Ultrasonic generators, also known as ultrasonic power supplies, electronic boxes, and ultrasonic controllers, are important components of high-power ultrasound systems. The ultrasonic generator is divided into an analog generator and a numerical control generator.

In the design of the ultrasonic power source, the matching design of the generator and the transducer is very important. The design of the intelligent ultrasonic generator largely determines whether the ultrasonic device can work normally and efficiently. The matching of the ultrasonic episode to the transducer includes two aspects: impedance matching and tuning matching. Impedance matching transforms the impedance of the transducer into an optimal load, ie, an impedance transformation. Tuning matching allows the voltage and current across the transducer to be in phase, resulting in the highest efficiency, while series resonance improves the voltage across the transducer, which is beneficial for piezoelectric transducers.

Troubleshooting when the ultrasonic generator is not working properly:

Ultrasonic equipment uses sound waves to perform work. How do we judge whether the ultrasonic generator is working properly or not when there is a problem with the ultrasonic equipment? First, we turn on the power switch on the ultrasonic power control box, press and hold the sound test button on the power box. When the button is pressed, observe the “amplifier” reading, and then listen to the sound. When the sound is not sharp, the current does not exceed 0.5A (aluminum When the current does not exceed 0.8A (steel mold), it is considered normal.

At the same time, if there is an overload indicator light or a harsh sound, or a hoarse sound, when the welding head is loose or the screw is broken, tighten the welding head or replace the screw to solve the problem. Appears during use, this is not the case with new machines.)

After the button of the sound wave detection is pressed, if the current meter shows that the current is high, there is a power and frequency adjustment switch on the right side of the point box to adjust the power gear position adjustment switch to the desired position (1 is the lowest gear position). The slow twisting FM switch adjusts the current to a minimum. (Under normal adjustment, it has been adjusted to the best condition at the factory)
