What is the ultrasonic generator for？Date: 2022-08-30Number: 219
The core component of an ultrasonic cleaning system is the ultrasonic generator, which provides electrical energy to the Ultrasonic transducer of the system. The ultrasonic generator's job is to receive the energy from the power supply and convert it to the appropriate frequency, voltage and ampere. Current from the power line is transmitted at a frequency of about 100 to 250 volts AC and 50 or 60 hertz. Most ultrasonic cleaning systems require an ultrasonic generator to power the Ultrasonic transducer at significantly higher voltages and specific frequencies for the operation of the ultrasonic cleaning system.
The choice of ultrasonic generator should be based on the application of specific cleaning requirements to achieve the best results. In addition to the power and frequency required to match the requirements of the transducer, the tank must be able to accommodate the largest part to be cleaned. In addition, power, frequency, and tank dimensions must be appropriate for the type of contaminant and the mechanical strength of the components involved in the cleaning application.
As a result of technological advances, ultrasonic generators are able to obtain feedback from the transducer, enabling them to maintain maximum ultrasonic cleaning by adjusting the frequency and power output. When necessary, the ultrasonic generator can provide customized waveform changes to optimize ultrasonic cleaning capabilities while reducing the possibility of part damage during cleaning.
The correct frequency is essential for effective ultrasonic cleaning. Low frequencies produce cleaning solutions with large, active cavitation bubbles. This method is most suitable for solid parts that are not damaged by hard surfaces that are less prone to pitting, as the cleaning effect generated by low frequencies is more powerful. Intermediate frequencies produce smaller cavitation bubbles, resulting in a milder cleaning effect. The highest frequency range is used for extremely sophisticated components such as medical components and electronic component.
A single frequency ultrasonic generator is usually used when a single process requires ultrasonic cleaning involving the same type of parts. A multi-frequency ultrasonic generator capable of generating multiple frequencies can also be used in facilities requiring ultrasonic parts cleaning for various parts with different characteristics.
