The generator circuit of multi-frequency ultrasonic cleaning machine includes control circuit, oscillation circuit, power output circuit. There are two or more different frequencies of ultrasonic transducer installed in the cleaning cylinder, by multiple generators to promote the respective frequency of the ultrasonic transducer. At the same time there are a variety of frequency of ultrasonic waves in the cylinder, cleaning more uniform. This ultrasonic cleaning machine is a modern combination of ultrasonic cleaning machine.
The main application scenario of multi-frequency ultrasonic cleaner
The main function of multi-frequency ultrasonic cleaner is used in laboratory, medical decontamination, biochemistry, microbiology, pharmacology, physics, zoology, agronomy, food, pharmaceutical and other industries special apparatus cleaning and analysis of the object of sample pretreatment, crushing, emulsification, dispersion, solubilization, extraction extraction, defoaming degassing, accelerated chemical reaction, nano-preparation, etc.
Ultrasonic cleaning machine is mainly used in the solution medium to produce the cavitation reaction to achieve the purpose of cleaning. Generated cavitation reaction and ultrasonic frequency has an inseparable relationship, the lower the frequency, the greater the amplitude, the larger the bubble generated in the medium, the greater the impact force naturally, but the weaker the penetration, and vice versa, the smaller the bubble generated, the smaller the strength naturally, but the stronger the penetration. Then there is a natural balance between the need to both the power and penetration. And 40KHZ is now a typical representative of the market.
But single-frequency ultrasonic cleaning machine for some units is not satisfied, this way of cleaning with a single tank machine is often easy to make the ultrasonic cleaning tank cleaning dead space, affecting the effective cleaning of the object. Like laboratories, pharmaceutical plants, research units, etc. sometimes need to use two or more different frequencies, applied in the same experiment, or cleaning the same precision parts, then this time in order to take into account the different needs or cleaning cleanliness needs, you may have to get two or three different single-frequency ultrasonic cleaner, so buy more than one device not only occupies a large space, cleaning costs naturally also Is going to increase a lot, and the use of a change to use very inconvenient. In order to meet the needs of the market in many aspects of cleaning, this time multi-frequency ultrasonic cleaning machine has emerged, that is, a variety of frequencies in one cleaning equipment, the market is often called multi-frequency ultrasonic cleaning machine or multi-frequency ultrasonic cleaning equipment.
The main feature of the multi-frequency ultrasonic cleaning machine is that you can switch different frequencies according to different cleaning needs, not only to achieve a machine also saves the cost of cleaning, free of multiple equipment replacement operation using the complexity of the use and so on. In the ultrasonic cleaning, the frequency of high and low cleaning efficacy is different, the ultrasonic frequency is higher when the cavitation intensity in the liquid is low, high density, high-frequency ultrasound can reach deeper grooves, slits, deep holes; while the ultrasonic frequency is low, the cavitation intensity is high, the number of bubbles and the object surface cleaning effect is large.
