超聲波清(qīng)洗機原理主要(yào)是將換能器,將功率超聲頻源的聲能,並且要轉換成機械振動,通過清洗槽壁使之將槽子中的清洗液(yè)輻射到超聲波。由於受到輻射的超聲波,使之槽(cáo)內液(yè)體中的微氣泡能夠在聲波的作用下從而保持振動(dòng)。
The principle of ultrasonic cleaning machine is to convert the ultrasonic energy of transducer and power ultrasonic frequency source into mechanical vibration, and make the cleaning solution in the tank radiate to ultrasonic through cleaning the tank wall. Because of the ultrasonic radiation, the microbubbles in the liquid in the tank can keep vibration under the action of acoustic wave.
當(dāng)聲壓或者聲強受(shòu)到壓力到達一定程度時(shí)候,氣泡(pào)就會迅速膨脹,然(rán)後又突然閉(bì)合。在這段過程中,氣泡閉合的瞬間產(chǎn)生衝(chōng)擊波,使氣(qì)泡周圍產生1012-1013pa的壓(yā)力及局調溫,這種超聲波(bō)空化所產生的巨大壓(yā)力(lì)能破壞不溶性汙物而(ér)使他們分化於溶液中(zhōng),蒸汽型空化對汙垢的直(zhí)接(jiē)反複衝擊。
When the sound pressure or sound intensity reaches a certain level, the bubble will expand rapidly and then close suddenly. In this process, shock wave is generated at the moment of bubble closure, which makes 1012-1013 PA pressure and local temperature around the bubble. The huge pressure generated by ultrasonic cavitation can destroy insoluble pollutants and make them differentiate into solution. The direct counter impact of steam cavitation on the fouling.
超聲波是一種振動頻率高於聲波的機械波,由換能晶片在電壓的激勵(lì)下發生振動(dòng)產生的(de),它具(jù)有頻率高、波長短、繞射現象小,特別是方向性好、能夠成(chéng)為射線而定向傳播等特點。
Ultrasonic wave is a kind of mechanical wave whose vibration frequency is higher than that of sound wave. It is generated by the vibration of transducer chip under the excitation of voltage. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, and can become a ray and propagate directionally.
超聲(shēng)波(bō)對液體、固體的(de)穿(chuān)透本領很大,尤其是在陽光不透明的固體中,它可穿透幾(jǐ)十米的深度。超(chāo)聲波碰到雜質或分界麵會產生顯著反射形(xíng)成反射成(chéng)回波,碰到活動物體(tǐ)能(néng)產(chǎn)生多普勒(lè)效應。因此超聲波檢測廣泛應用在工(gōng)業、國防、生物醫學等方麵。
Ultrasonic has great penetration ability to liquid and solid, especially in the opaque solid of sunlight, it can penetrate tens of meters deep. When the ultrasonic wave touches the impurity or interface, it will produce significant reflection and echo. When it touches the moving object, it will produce Doppler effect. Therefore, ultrasonic testing is widely used in industry, national defense, biomedicine and other aspects.
