超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)在(zai)液(ye)體(ti)(ti)中(zhong)傳播，使(shi)(shi)(shi)液(ye)體(ti)(ti)和清(qing)洗(xi)槽在(zai)超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)頻(pin)(pin)率(lv)下振(zhen)動(dong)(dong)，液(ye)體(ti)(ti)和清(qing)洗(xi)槽在(zai)自己的(de)固有(you)頻(pin)(pin)率(lv)（即(ji)聲(sheng)(sheng)(sheng)頻(pin)(pin)）下振(zhen)動(dong)(dong)，人們(men)聽到(dao)嗡(weng)嗡(weng)聲(sheng)(sheng)(sheng)。沿著(zhu)清(qing)洗(xi)行(xing)業(ye)的(de)發展，越(yue)來越(yue)多(duo)的(de)行(xing)業(ye)和企業(ye)使(shi)(shi)(shi)用超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)清(qing)洗(xi)機(ji)。依據超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)清(qing)洗(xi)器的(de)原(yuan)理(li)，來源于(yu)超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)換(huan)能器的(de)高(gao)(gao)頻(pin)(pin)率(lv)振(zhen)動(dong)(dong)數據信(xin)(xin)號根據超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)換(huan)能器轉(zhuan)換(huan)為(wei)(wei)(wei)高(gao)(gao)頻(pin)(pin)率(lv)現(xian)代控(kong)制(zhi)理(li)論(lun)，散播到(dao)做為(wei)(wei)(wei)物(wu)質的(de)清(qing)理(li)有(you)機(ji)溶(rong)(rong)劑中(zhong)，超(chao)(chao)(chao)(chao)音波(bo)在(zai)清(qing)潔液(ye)中(zhong)粗密地前后(hou)左(zuo)右(you)放射性，使(shi)(shi)(shi)液(ye)體(ti)(ti)流動(dong)(dong)性而造成(cheng)數十萬米(mi)的(de)直徑50-500μm的(de)細微汽泡，液(ye)體(ti)(ti)中(zhong)存有(you)的(de)細微汽泡在(zai)音場(chang)中(zhong)振(zhen)動(dong)(dong)。這些(xie)氣(qi)(qi)泡形成(cheng)并生(sheng)長在(zai)超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)縱向傳輸負(fu)壓(ya)(ya)區,而在(zai)正壓(ya)(ya)區,當聲(sheng)(sheng)(sheng)壓(ya)(ya)達到(dao)一(yi)定(ding)值時,氣(qi)(qi)泡迅速增加(jia),然(ran)后(hou)突然(ran)關閉(bi)。并在(zai)氣(qi)(qi)泡閉(bi)合時產(chan)生(sheng)沖擊波(bo)，在(zai)其周(zhou)圍產(chan)生(sheng)上千個(ge)大氣(qi)(qi)壓(ya)(ya)，破(po)壞(huai)不溶(rong)(rong)性污(wu)(wu)物(wu)而使(shi)(shi)(shi)他們(men)分散于(yu)清(qing)洗(xi)液(ye)中(zhong)，當團(tuan)體(ti)(ti)粒(li)子(zi)被油污(wu)(wu)裹著(zhu)而黏附在(zai)清(qing)洗(xi)件(jian)表面時，油被乳化(hua)(hua)，固體(ti)(ti)粒(li)子(zi)及脫離(li)，從(cong)而達到(dao)清(qing)洗(xi)件(jian)凈(jing)化(hua)(hua)的(de)目的(de)。在(zai)這種被稱之為(wei)(wei)(wei)“空(kong)化(hua)(hua)”效(xiao)應的(de)過程中(zhong)，氣(qi)(qi)泡閉(bi)合可形成(cheng)幾百度(du)的(de)高(gao)(gao)溫和超(chao)(chao)(chao)(chao)過1000個(ge)氣(qi)(qi)壓(ya)(ya)的(de)瞬(shun)間高(gao)(gao)壓(ya)(ya)。超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)清(qing)洗(xi)機(ji)的(de)優點是(shi)：超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)清(qing)洗(xi)效(xiao)果(guo)好，操作簡單。人們(men)聽到(dao)的(de)聲(sheng)(sheng)(sheng)音是(shi)20-20000Hz頻(pin)(pin)率(lv)高(gao)(gao)于(yu)20000Hz的(de)聲(sheng)(sheng)(sheng)波(bo)信(xin)(xin)號,稱為(wei)(wei)(wei)超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)。一(yi)個(ge)原(yuan)因是(shi)液(ye)體(ti)(ti)中(zhong)的(de)局(ju)部拉應力形成(cheng)負(fu)壓(ya)(ya),壓(ya)(ya)力的(de)減小使(shi)(shi)(shi)原(yuan)溶(rong)(rong)解氣(qi)(qi)體(ti)(ti)飽和,但從(cong)液(ye)體(ti)(ti)中(zhong)逃逸,成(cheng)為(wei)(wei)(wei)一(yi)個(ge)小泡;另一(yi)個(ge)原(yuan)因是(shi)強拉應力將液(ye)體(ti)(ti)撕裂成(cheng)一(yi)個(ge)孔,稱為(wei)(wei)(wei)空(kong)化(hua)(hua)。
