超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)在(zai)液(ye)體(ti)中(zhong)(zhong)(zhong)(zhong)傳播(bo)，使液(ye)體(ti)和清(qing)(qing)洗(xi)(xi)(xi)(xi)槽(cao)在(zai)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)頻率下振動(dong)(dong)，液(ye)體(ti)和清(qing)(qing)洗(xi)(xi)(xi)(xi)槽(cao)在(zai)自己的(de)(de)(de)(de)(de)固有頻率（即聲(sheng)(sheng)(sheng)頻）下振動(dong)(dong)，人們聽到(dao)(dao)嗡嗡聲(sheng)(sheng)(sheng)。沿著清(qing)(qing)洗(xi)(xi)(xi)(xi)行業的(de)(de)(de)(de)(de)發展，越來(lai)越多的(de)(de)(de)(de)(de)行業和企業使用超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)洗(xi)(xi)(xi)(xi)機(ji)。依(yi)據(ju)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)洗(xi)(xi)(xi)(xi)器的(de)(de)(de)(de)(de)原理(li)(li)，來(lai)源(yuan)于超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)換能器的(de)(de)(de)(de)(de)高頻率振動(dong)(dong)數據(ju)信(xin)(xin)號根據(ju)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)換能器轉換為(wei)(wei)(wei)高頻率現代(dai)控制(zhi)理(li)(li)論，散播(bo)到(dao)(dao)做為(wei)(wei)(wei)物質(zhi)的(de)(de)(de)(de)(de)清(qing)(qing)理(li)(li)有機(ji)溶(rong)劑中(zhong)(zhong)(zhong)(zhong)，超(chao)(chao)(chao)音(yin)(yin)波(bo)(bo)在(zai)清(qing)(qing)潔液(ye)中(zhong)(zhong)(zhong)(zhong)粗密地前后左右放射性(xing)，使液(ye)體(ti)流動(dong)(dong)性(xing)而(er)(er)造成數十萬米的(de)(de)(de)(de)(de)直徑50-500μm的(de)(de)(de)(de)(de)細微汽泡(pao)，液(ye)體(ti)中(zhong)(zhong)(zhong)(zhong)存(cun)有的(de)(de)(de)(de)(de)細微汽泡(pao)在(zai)音(yin)(yin)場中(zhong)(zhong)(zhong)(zhong)振動(dong)(dong)。這些氣(qi)泡(pao)形(xing)成并(bing)生長在(zai)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)縱向傳輸(shu)負壓(ya)(ya)區,而(er)(er)在(zai)正壓(ya)(ya)區,當(dang)聲(sheng)(sheng)(sheng)壓(ya)(ya)達到(dao)(dao)一(yi)定(ding)值時,氣(qi)泡(pao)迅速增加,然(ran)后突然(ran)關(guan)閉。并(bing)在(zai)氣(qi)泡(pao)閉合時產生沖(chong)擊(ji)波(bo)(bo)，在(zai)其(qi)周圍產生上(shang)千個(ge)大氣(qi)壓(ya)(ya)，破(po)壞不溶(rong)性(xing)污物而(er)(er)使他(ta)們分散于清(qing)(qing)洗(xi)(xi)(xi)(xi)液(ye)中(zhong)(zhong)(zhong)(zhong)，當(dang)團體(ti)粒子被(bei)油污裹著而(er)(er)黏附(fu)在(zai)清(qing)(qing)洗(xi)(xi)(xi)(xi)件表面時，油被(bei)乳化，固體(ti)粒子及脫離，從(cong)(cong)而(er)(er)達到(dao)(dao)清(qing)(qing)洗(xi)(xi)(xi)(xi)件凈化的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。在(zai)這種被(bei)稱之為(wei)(wei)(wei)“空化”效應的(de)(de)(de)(de)(de)過程(cheng)中(zhong)(zhong)(zhong)(zhong)，氣(qi)泡(pao)閉合可形(xing)成幾百(bai)度的(de)(de)(de)(de)(de)高溫和超(chao)(chao)(chao)過1000個(ge)氣(qi)壓(ya)(ya)的(de)(de)(de)(de)(de)瞬間(jian)高壓(ya)(ya)。超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)洗(xi)(xi)(xi)(xi)機(ji)的(de)(de)(de)(de)(de)優點是(shi)：超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)洗(xi)(xi)(xi)(xi)效果好，操作簡單。人們聽到(dao)(dao)的(de)(de)(de)(de)(de)聲(sheng)(sheng)(sheng)音(yin)(yin)是(shi)20-20000Hz頻率高于20000Hz的(de)(de)(de)(de)(de)聲(sheng)(sheng)(sheng)波(bo)(bo)信(xin)(xin)號,稱為(wei)(wei)(wei)超(chao)(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)(bo)。一(yi)個(ge)原因是(shi)液(ye)體(ti)中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)(de)(de)局部(bu)拉應力形(xing)成負壓(ya)(ya),壓(ya)(ya)力的(de)(de)(de)(de)(de)減(jian)小(xiao)使原溶(rong)解氣(qi)體(ti)飽和,但從(cong)(cong)液(ye)體(ti)中(zhong)(zhong)(zhong)(zhong)逃逸,成為(wei)(wei)(wei)一(yi)個(ge)小(xiao)泡(pao);另一(yi)個(ge)原因是(shi)強拉應力將液(ye)體(ti)撕(si)裂成一(yi)個(ge)孔,稱為(wei)(wei)(wei)空化。
