Ultrasonic cleaning generator
Ultrasonic generator is the role of the city into a high frequency alternating current signal with ultrasonic transducer, driven by ultrasonic transducer. High power ultrasonic power supply from the conversion efficiency considerations generally use the circuit form of switching power supply.
Ultrasonic power supply is divided into self excited type and its excitation power, self excited power called ultrasonic power, which is called ultrasonic cleaning generator.
28khz and 40khz,40khz and 80khz
Ultrasonic generator to generate a specific frequency signal, this signal can be sine signal, it is the frequency of ultrasonic transducer, the ultrasonic frequency is 25KHz, 28KHz, 35KHz, 40KHz, 100KHz believe that the use of the feedback signal: first is to provide output power signal, we know that when the ultrasonic generator output power will change, and then reflect on the ultrasonic transducer is mechanical vibration. The device, which makes the power amplifier stable. The second is to provide frequency tracking signal. When the ultrasonic transducer work at the resonance frequency of the highest, work the most stable, and ultrasonic transducer resonant frequency point will be the cause of the assembly and work after aging change, of course, the frequency of this change is only drift, change is not great, frequency tracking signal can control signal ultrasonic generator, frequency in a certain range of ultrasonic generator tracking ultrasonic transducer resonant frequency.
Ultrasonic cleaning generator is an important part of ultrasonic equipment, which is responsible for providing the ultrasonic transducer with ultrasonic frequency generator. In order to make the transducer work efficiently, not only the electric energy supplied by the generator is sufficient, but also the frequency of the transducer is consistent with the resonance frequency of the transducer. In general, the resonance frequency of the transducer can be changed due to heat, load change, aging and so on. Because in addition to the transducer loss caused by heat, welding tools hair heat is difficult to avoid. All of these factors will caused shift of the resonance frequency of the transducer. If the oscillation frequency of the generator is not adjusted, the working state of the transducer will be changed. It is not only inefficient to adjust the frequency of manual (manual) method, but it is not suitable for automatic production. Therefore, it is required that the generator has the function of automatically adjusting the frequency.
