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.
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.
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
The ultrasonic generators produced by our company have the
- 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.
