Working principle and structural characteristics of 200kHz ultrasonic cleaning machine
Date: 2025-11-19Read: 1
The 200kHz ultrasonic cleaning machine works on the same principle as traditional ultrasonic cleaning machines, both utilizing the propagation of ultrasonic waves through liquid media to generate cavitation effects. The cavitation effect refers to the formation of tiny bubbles when ultrasound propagates in liquid, which continuously expand and collapse, releasing strong energy and generating high pressure and temperature, thereby removing dirt from the surface of objects. Compared to low-frequency ultrasonic cleaning machines (such as 20kHz, 40kHz), it has different characteristics.
200KHZ ultrasonic cleaning machineThe specific principle is as follows:
1. Generation of high-frequency ultrasound:
It converts electrical energy into mechanical energy through an ultrasonic generator and converts electrical signals into ultrasonic waves through a transducer. These fluctuations propagate at very high frequencies in liquids.
2. Formation of cavitation effect:
When ultrasound propagates in liquid, it causes violent vibrations of liquid molecules, resulting in the formation of a large number of tiny bubbles. These bubbles constantly expand and compress, ultimately leading to the collapse of the bubbles and the release of strong energy. This energy produces small impacts and frictional forces on the surface of an object, causing dirt or pollutants on the surface to detach from the surface.
3. Delicate cleaning of high-frequency vibration:
A high frequency of 200kHz means generating 200000 fluctuations per second. Compared with low-frequency ultrasound, high-frequency ultrasound has a more detailed and uniform cavitation effect, which can effectively remove small dirt and particles, especially suitable for cleaning high-precision equipment.
4. The function of ultrasonic cleaning solution:
Usually, specialized cleaning solutions are used during ultrasonic cleaning to improve the cleaning effect. Cleaning solution not only helps improve the transmission effect of ultrasonic waves, but also removes different types of pollutants such as grease, dust, rust, etc., enhancing the cleaning effect.
Composition and structure of 200kHz ultrasonic cleaning machine:
1. Cleaning tank:
The cleaning tank is the basic part of the ultrasonic cleaning machine, used to hold cleaning solution and items to be cleaned. The cleaning tank is generally made of stainless steel material to enhance corrosion resistance and compression resistance. The cleaning tank is usually equipped with a uniform ultrasonic wave zone inside, ensuring that every corner can be cleaned.
2. Ultrasonic transducer:
The transducer is a key component that converts electrical energy into mechanical energy. Transducers usually contain piezoelectric ceramics, which generate small mechanical vibrations under the action of electrical signals and transmit these vibrations to the cleaning solution. The number and arrangement of transducers will affect the cleaning effect of ultrasonic waves.
3. Ultrasonic generator:
The ultrasonic generator is responsible for converting the power input into ultrasonic frequency. It can control the ultrasonic frequency generated by the transducer by adjusting the output current and voltage. The signal output by the generator can be maintained at a frequency of 200kHz to meet high-precision cleaning requirements.
4. Heating system (optional):
Some are also equipped with heating systems to increase the temperature of the cleaning solution. The increase in temperature can help dissolve grease and dirt, enhance cleaning effectiveness, especially when cleaning oily substances, which can significantly improve cleaning efficiency.
5. Control panel:
The control panel is the interface for user device interaction. Users can adjust the working time, frequency, heating temperature and other parameters of ultrasonic waves through the control panel. Some devices are also equipped with digital displays that show real-time working status and related parameters.
6. Solution filtration system (optional):
It may also be equipped with a solution filtration system. This system can filter impurities generated during the cleaning process, maintain the cleanliness of the cleaning solution, and ensure that the cleaning effect is not affected.
