超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)在(zai)(zai)液(ye)體(ti)(ti)中(zhong)(zhong)(zhong)(zhong)傳播，使(shi)液(ye)體(ti)(ti)和(he)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)槽在(zai)(zai)超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)頻率下振(zhen)動(dong)，液(ye)體(ti)(ti)和(he)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)槽在(zai)(zai)自己的(de)(de)固(gu)有(you)頻率（即聲(sheng)(sheng)(sheng)(sheng)頻）下振(zhen)動(dong)，人們聽到(dao)嗡(weng)嗡(weng)聲(sheng)(sheng)(sheng)(sheng)。沿(yan)著(zhu)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)行業的(de)(de)發展，越來(lai)(lai)越多的(de)(de)行業和(he)企業使(shi)用超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機(ji)。依(yi)據超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)器(qi)的(de)(de)原(yuan)理，來(lai)(lai)源于(yu)超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)換能器(qi)的(de)(de)高(gao)頻率振(zhen)動(dong)數據信號(hao)根(gen)據超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)換能器(qi)轉換為高(gao)頻率現(xian)代(dai)控制理論，散播到(dao)做為物質的(de)(de)清(qing)(qing)(qing)理有(you)機(ji)溶(rong)劑中(zhong)(zhong)(zhong)(zhong)，超(chao)音波(bo)(bo)(bo)在(zai)(zai)清(qing)(qing)(qing)潔(jie)液(ye)中(zhong)(zhong)(zhong)(zhong)粗(cu)密地前后(hou)左右放射性(xing)，使(shi)液(ye)體(ti)(ti)流動(dong)性(xing)而(er)造成數十(shi)萬米的(de)(de)直(zhi)徑50-500μm的(de)(de)細微汽泡(pao)(pao)，液(ye)體(ti)(ti)中(zhong)(zhong)(zhong)(zhong)存有(you)的(de)(de)細微汽泡(pao)(pao)在(zai)(zai)音場中(zhong)(zhong)(zhong)(zhong)振(zhen)動(dong)。這些(xie)氣(qi)泡(pao)(pao)形成并(bing)生長在(zai)(zai)超(chao)聲(sheng)(sheng)(sheng)(sheng)縱向傳輸(shu)負(fu)壓(ya)(ya)區(qu),而(er)在(zai)(zai)正壓(ya)(ya)區(qu),當(dang)聲(sheng)(sheng)(sheng)(sheng)壓(ya)(ya)達到(dao)一(yi)(yi)定(ding)值時,氣(qi)泡(pao)(pao)迅速(su)增加,然(ran)后(hou)突然(ran)關閉。并(bing)在(zai)(zai)氣(qi)泡(pao)(pao)閉合時產生沖(chong)擊波(bo)(bo)(bo)，在(zai)(zai)其(qi)周圍(wei)產生上千個(ge)(ge)大氣(qi)壓(ya)(ya)，破(po)壞不溶(rong)性(xing)污物而(er)使(shi)他們分散于(yu)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)中(zhong)(zhong)(zhong)(zhong)，當(dang)團體(ti)(ti)粒子被油(you)污裹著(zhu)而(er)黏附在(zai)(zai)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)件(jian)表(biao)面時，油(you)被乳化，固(gu)體(ti)(ti)粒子及脫離，從(cong)而(er)達到(dao)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)件(jian)凈(jing)化的(de)(de)目的(de)(de)。在(zai)(zai)這種被稱之為“空(kong)化”效應的(de)(de)過程(cheng)中(zhong)(zhong)(zhong)(zhong)，氣(qi)泡(pao)(pao)閉合可形成幾(ji)百度的(de)(de)高(gao)溫和(he)超(chao)過1000個(ge)(ge)氣(qi)壓(ya)(ya)的(de)(de)瞬間高(gao)壓(ya)(ya)。超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機(ji)的(de)(de)優點是(shi)：超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果好，操(cao)作(zuo)簡單。人們聽到(dao)的(de)(de)聲(sheng)(sheng)(sheng)(sheng)音是(shi)20-20000Hz頻率高(gao)于(yu)20000Hz的(de)(de)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)信號(hao),稱為超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)(bo)。一(yi)(yi)個(ge)(ge)原(yuan)因是(shi)液(ye)體(ti)(ti)中(zhong)(zhong)(zhong)(zhong)的(de)(de)局(ju)部拉應力形成負(fu)壓(ya)(ya),壓(ya)(ya)力的(de)(de)減小(xiao)使(shi)原(yuan)溶(rong)解氣(qi)體(ti)(ti)飽(bao)和(he),但從(cong)液(ye)體(ti)(ti)中(zhong)(zhong)(zhong)(zhong)逃逸,成為一(yi)(yi)個(ge)(ge)小(xiao)泡(pao)(pao);另一(yi)(yi)個(ge)(ge)原(yuan)因是(shi)強拉應力將液(ye)體(ti)(ti)撕裂成一(yi)(yi)個(ge)(ge)孔,稱為空(kong)化。
