超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)在(zai)液(ye)體(ti)(ti)(ti)(ti)中(zhong)(zhong)傳播，使(shi)(shi)液(ye)體(ti)(ti)(ti)(ti)和清(qing)(qing)(qing)洗(xi)(xi)槽(cao)在(zai)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)頻(pin)(pin)(pin)率(lv)(lv)(lv)下振(zhen)動(dong)，液(ye)體(ti)(ti)(ti)(ti)和清(qing)(qing)(qing)洗(xi)(xi)槽(cao)在(zai)自己的(de)(de)(de)固(gu)(gu)有(you)頻(pin)(pin)(pin)率(lv)(lv)(lv)（即聲(sheng)(sheng)(sheng)頻(pin)(pin)(pin)）下振(zhen)動(dong)，人們聽到(dao)嗡嗡聲(sheng)(sheng)(sheng)。沿著(zhu)清(qing)(qing)(qing)洗(xi)(xi)行(xing)業的(de)(de)(de)發展(zhan)，越(yue)來越(yue)多的(de)(de)(de)行(xing)業和企(qi)業使(shi)(shi)用超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)洗(xi)(xi)機(ji)。依(yi)據(ju)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)洗(xi)(xi)器的(de)(de)(de)原理，來源(yuan)于(yu)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)換能(neng)器的(de)(de)(de)高頻(pin)(pin)(pin)率(lv)(lv)(lv)振(zhen)動(dong)數據(ju)信號根據(ju)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)換能(neng)器轉換為(wei)高頻(pin)(pin)(pin)率(lv)(lv)(lv)現代控制理論，散(san)(san)播到(dao)做為(wei)物質的(de)(de)(de)清(qing)(qing)(qing)理有(you)機(ji)溶(rong)劑(ji)中(zhong)(zhong)，超(chao)(chao)(chao)音波(bo)(bo)在(zai)清(qing)(qing)(qing)潔液(ye)中(zhong)(zhong)粗密地(di)前后(hou)(hou)左(zuo)右放射性(xing)，使(shi)(shi)液(ye)體(ti)(ti)(ti)(ti)流動(dong)性(xing)而(er)造成(cheng)(cheng)(cheng)數十萬米的(de)(de)(de)直徑(jing)50-500μm的(de)(de)(de)細微汽(qi)泡(pao)，液(ye)體(ti)(ti)(ti)(ti)中(zhong)(zhong)存有(you)的(de)(de)(de)細微汽(qi)泡(pao)在(zai)音場(chang)中(zhong)(zhong)振(zhen)動(dong)。這(zhe)些氣泡(pao)形成(cheng)(cheng)(cheng)并生長在(zai)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)縱(zong)向傳輸負(fu)壓區,而(er)在(zai)正壓區,當聲(sheng)(sheng)(sheng)壓達到(dao)一(yi)定(ding)值時(shi),氣泡(pao)迅速(su)增(zeng)加,然(ran)后(hou)(hou)突然(ran)關閉(bi)(bi)。并在(zai)氣泡(pao)閉(bi)(bi)合時(shi)產生沖擊(ji)波(bo)(bo)，在(zai)其周(zhou)圍產生上千個(ge)大氣壓，破壞不溶(rong)性(xing)污(wu)物而(er)使(shi)(shi)他們分散(san)(san)于(yu)清(qing)(qing)(qing)洗(xi)(xi)液(ye)中(zhong)(zhong)，當團體(ti)(ti)(ti)(ti)粒(li)子被(bei)油污(wu)裹著(zhu)而(er)黏(nian)附在(zai)清(qing)(qing)(qing)洗(xi)(xi)件表面時(shi)，油被(bei)乳化，固(gu)(gu)體(ti)(ti)(ti)(ti)粒(li)子及脫離，從而(er)達到(dao)清(qing)(qing)(qing)洗(xi)(xi)件凈(jing)化的(de)(de)(de)目(mu)的(de)(de)(de)。在(zai)這(zhe)種(zhong)被(bei)稱(cheng)之為(wei)“空(kong)化”效(xiao)應(ying)的(de)(de)(de)過程中(zhong)(zhong)，氣泡(pao)閉(bi)(bi)合可形成(cheng)(cheng)(cheng)幾百度的(de)(de)(de)高溫和超(chao)(chao)(chao)過1000個(ge)氣壓的(de)(de)(de)瞬(shun)間(jian)高壓。超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)洗(xi)(xi)機(ji)的(de)(de)(de)優點(dian)是(shi)：超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)洗(xi)(xi)效(xiao)果好，操(cao)作簡單。人們聽到(dao)的(de)(de)(de)聲(sheng)(sheng)(sheng)音是(shi)20-20000Hz頻(pin)(pin)(pin)率(lv)(lv)(lv)高于(yu)20000Hz的(de)(de)(de)聲(sheng)(sheng)(sheng)波(bo)(bo)信號,稱(cheng)為(wei)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)。一(yi)個(ge)原因是(shi)液(ye)體(ti)(ti)(ti)(ti)中(zhong)(zhong)的(de)(de)(de)局部拉應(ying)力(li)形成(cheng)(cheng)(cheng)負(fu)壓,壓力(li)的(de)(de)(de)減小使(shi)(shi)原溶(rong)解氣體(ti)(ti)(ti)(ti)飽(bao)和,但(dan)從液(ye)體(ti)(ti)(ti)(ti)中(zhong)(zhong)逃(tao)逸,成(cheng)(cheng)(cheng)為(wei)一(yi)個(ge)小泡(pao);另一(yi)個(ge)原因是(shi)強拉應(ying)力(li)將液(ye)體(ti)(ti)(ti)(ti)撕裂成(cheng)(cheng)(cheng)一(yi)個(ge)孔,稱(cheng)為(wei)空(kong)化。
