The blue whale takes you into the inner world of the ultrasonic washer machine
An ultrasonic wave is a sound wave with a frequency higher than 20000 Hz. It has good directivity, strong penetrating ability, and easy to obtain more concentrated sound energy. And it can travel long distances in water. It can be used for ranging, speed measurement, cleaning, welding, gravel, sterilization, and other disinfection. It has many applications in medicine, military affairs, industry, and agriculture. Ultrasound is so named because the lower limit of its frequency is approximately equal to the upper limit of human hearing.
So, what is the working principle of the ultrasonic washer machine? What are the main links and steps?
The principle of an ultrasonic cleaning machine is to convert the sound energy of the transducer and the power ultrasonic frequency source into mechanical vibration. And to radiate the cleaning liquid in the tank to the ultrasonic wave by cleaning the tank wall.
Due to the radiated ultrasound, the micro-bubbles in the liquid in the groove can keep vibration under the action of sound waves. When the sound pressure or the sound strong is stressed to a certain extent, the bubbles will expand quickly and then close suddenly. During this process, the instantaneous wave of the bubbles was closed, causing the pressure and temperature adjustment of 1012-1013Pa around the bubbles. The huge pressure generated by this ultrasonic vacuum can destroy insoluble dirt and differentiate them in the solution. Steam -type is then a direct impact on dirt.
With this knowledge, we have only a preliminary understanding of its inner "World". What is it like inside?
It can do just as we human beings think, it has a deep desire to give this society and the world its modest efforts to add a little bit of green to the Earth. At the same time, it is advocating that we should be green, and healthy. And cleanliness can be the guide. It can adhere to the road of sustainable development.
So, how does the ultrasonic washer machine add a little "green" to society and the world?
On the one hand, it destroys the adsorption between the dirt and the surface of the cleaning part, on the other hand, it can cause fatigue damage to the dirt layer and be separated from it. The vibration of the gas-type bubble will scrub the solid surface. Once the dirt layer has a seam, it can be drilled, the bubble immediately "drills" the vibration to cause the dirty layer to fall off. Because of the cavitation, the two kinds of liquid quickly disperse and empty in the interface. When the solid particle is wrapped by the oil pollution and sticks to the surface of the cleaning part, the oil is emptied and the solid particles fall off by themselves. When the ultrasonic wave propagates in the cleaning fluid, it will produce a positive and negative alternating sound pressure. It will form a jet and impact the cleaning part. At the same time, the non-linear effect will produce a sound flow and a micro-sound flow. Ultrasonic cavitation can produce high-speed micro-jet at the solid and liquid interface. All these effects can destroy dirt, remove or weaken the boundary dirt layer, and increase stirring and diffusion. And accelerate the dissolution of soluble dirt, strengthening the cleaning action of the chemical cleaning agent.
It can be seen that all the liquids can be immersed and the sound field has a cleaning effect. It is characterized by the cleaning of parts with very complex surface shapes. Especially after using this technology, the number of chemical solvents can be reduced. Thereby it greatly reduces environmental pollution.
It also has the following cleaning advantages: the effect of ultrasonic cleaning equipment is very good. The cleaning degree is high. The cleaning speed is fast. It is no need to contact the cleaning agent. It is safe and reliable. And there is no damage to the surface of the workpiece. It can save heat energy, cleaning agent, venue, and labor.
And better than conventional cleaning: especially for the workpiece surface more complex, bumpy, with blind hole mechanical parts, high precision products such as clocks, electronic components, circuit boards, etc. Using an ultrasonic washer machine can achieve very good results. At present, the industries we have come into contact with. They are using ultrasonic washer machines to clean glasses, watches, plastics, glass, machinery, electronics, jewelry, medical, hardware, bearings, hydraulic, aviation, ceramics, chemical fiber, pre-plating processing, and so on. It can be said to involve all aspects of modern industrial products. ultrasonic washer machine has shown great advantages. It will gradually replace the traditional cleaning methods.
