High Efficiency Ultrasonic Cleaning Transducer Stable Operation With Feedback Link

^{High Efficiency Ultrasonic Cleaning Transducer Stable Operation With Feedback Link}

^{What is the feedback signal of the ultrasonic generator and the advantages of our generator:
The perfect ultrasonic generator has a feedback link, which mainly provides feedback signals in the following two aspects.}

^{Output Power
When the ultrasonic generator input voltage changes, the output power of the generator also changes. The mechanical vibration of the ultrasonic transducer is unstable, resulting in poor working results. Therefore, it is necessary to stabilize the output power, and the power amplifier is adjusted correspondingly by the power feedback signal, so that the power amplification is stable.}

^{Frequency tracking
The transducer operates at the resonant frequency point with the highest efficiency and the most stable operation. The resonant frequency point of the transducer changes due to assembly and aging. If the changed frequency is only drifting, the change is not large, the frequency tracking signal can control the signal generator, so that the frequency of the signal generator tracks the resonant frequency point of the transducer within a certain range, so that the generator works at an optimal state.
The ultrasonic generator can monitor the operating frequency and power of the high-power ultrasonic system.
It can adjust various parameters in real time according to different requirements of users: such as power, amplitude, running time and so on.}

^{The advantages of Cheng Chengshan ultrasonic generator:
The super-audio electrical signal generated by the ultrasonic generator above 28 kHz is converted into mechanical oscillation of the same frequency by the piezoelectric inverse effect of the transducer, and is radiated in the cleaning liquid in the form of super-audio longitudinal waves. Due to the alternating positive and negative pressures of the super-audio longitudinal wave propagation, numerous tiny bubbles of more than 1000 atmospheres are generated and blasted at any time to form a fine local high-pressure bombardment on the surface of the cleaning object, so that the dirt on the surface and the gap of the object is rapidly peeled off. This is the "cavitation effect" unique to ultrasonic cleaning.}

^{The ultrasonic generators produced by our company have the following characteristics:}

• ^{Frequency fine-tuning: The frequency is adjusted so that the ultrasonic transducer always works at its optimum state, and the efficiency is maximized, and the adjustment range is 2%. Auto-following: Once the device has been initially set up, it can be operated continuously without the need to adjust the generator.}
• ^{Amplitude control: When the load changes during the operation of the transducer, the drive characteristics can be automatically adjusted to ensure a stable amplitude of the tool head.}
• ^{System protection: When the system works in an unsuitable operating environment, the generator will stop working and display an alarm to protect the device from damage.}
• ^{Amplitude adjustment: The amplitude can be increased or decreased instantaneously during the working process, and the amplitude setting range is 0%~100%.}
• ^{Automatic frequency search: The working frequency of the tool head can be automatically determined and stored.}
