超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)在(zai)(zai)液(ye)體中(zhong)(zhong)(zhong)(zhong)傳播(bo)，使(shi)(shi)(shi)液(ye)體和(he)(he)(he)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)槽在(zai)(zai)超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)頻(pin)率下振動(dong)，液(ye)體和(he)(he)(he)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)槽在(zai)(zai)自己(ji)的(de)(de)(de)(de)固有頻(pin)率（即(ji)聲(sheng)(sheng)頻(pin)）下振動(dong)，人(ren)們(men)聽到(dao)嗡嗡聲(sheng)(sheng)。沿著清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)行業(ye)的(de)(de)(de)(de)發展，越來越多的(de)(de)(de)(de)行業(ye)和(he)(he)(he)企業(ye)使(shi)(shi)(shi)用超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)機。依據超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)器的(de)(de)(de)(de)原理(li)，來源(yuan)于超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)換(huan)能器的(de)(de)(de)(de)高(gao)頻(pin)率振動(dong)數(shu)據信號根(gen)據超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)換(huan)能器轉換(huan)為(wei)(wei)(wei)高(gao)頻(pin)率現代控制理(li)論，散播(bo)到(dao)做(zuo)為(wei)(wei)(wei)物(wu)質的(de)(de)(de)(de)清(qing)(qing)(qing)(qing)(qing)理(li)有機溶(rong)劑中(zhong)(zhong)(zhong)(zhong)，超(chao)(chao)(chao)音(yin)(yin)(yin)波(bo)(bo)(bo)(bo)在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)潔(jie)液(ye)中(zhong)(zhong)(zhong)(zhong)粗(cu)密地前后左右放射性(xing)，使(shi)(shi)(shi)液(ye)體流動(dong)性(xing)而(er)造成數(shu)十萬米的(de)(de)(de)(de)直(zhi)徑50-500μm的(de)(de)(de)(de)細(xi)微(wei)汽泡(pao)(pao)，液(ye)體中(zhong)(zhong)(zhong)(zhong)存(cun)有的(de)(de)(de)(de)細(xi)微(wei)汽泡(pao)(pao)在(zai)(zai)音(yin)(yin)(yin)場(chang)中(zhong)(zhong)(zhong)(zhong)振動(dong)。這些氣(qi)(qi)(qi)泡(pao)(pao)形成并生長在(zai)(zai)超(chao)(chao)(chao)聲(sheng)(sheng)縱向傳輸負(fu)壓區,而(er)在(zai)(zai)正壓區,當聲(sheng)(sheng)壓達到(dao)一(yi)定值時(shi),氣(qi)(qi)(qi)泡(pao)(pao)迅速增加,然(ran)后突(tu)然(ran)關閉(bi)(bi)。并在(zai)(zai)氣(qi)(qi)(qi)泡(pao)(pao)閉(bi)(bi)合(he)時(shi)產生沖擊波(bo)(bo)(bo)(bo)，在(zai)(zai)其周圍(wei)產生上千(qian)個(ge)大氣(qi)(qi)(qi)壓，破壞不溶(rong)性(xing)污物(wu)而(er)使(shi)(shi)(shi)他們(men)分散于清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)液(ye)中(zhong)(zhong)(zhong)(zhong)，當團體粒子被油污裹著而(er)黏附在(zai)(zai)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)件(jian)表面時(shi)，油被乳化(hua)(hua)(hua)，固體粒子及脫離，從而(er)達到(dao)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)件(jian)凈(jing)化(hua)(hua)(hua)的(de)(de)(de)(de)目的(de)(de)(de)(de)。在(zai)(zai)這種被稱之(zhi)為(wei)(wei)(wei)“空化(hua)(hua)(hua)”效(xiao)應的(de)(de)(de)(de)過程中(zhong)(zhong)(zhong)(zhong)，氣(qi)(qi)(qi)泡(pao)(pao)閉(bi)(bi)合(he)可形成幾百度(du)的(de)(de)(de)(de)高(gao)溫和(he)(he)(he)超(chao)(chao)(chao)過1000個(ge)氣(qi)(qi)(qi)壓的(de)(de)(de)(de)瞬間高(gao)壓。超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)機的(de)(de)(de)(de)優點是(shi)：超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)效(xiao)果好，操作簡單。人(ren)們(men)聽到(dao)的(de)(de)(de)(de)聲(sheng)(sheng)音(yin)(yin)(yin)是(shi)20-20000Hz頻(pin)率高(gao)于20000Hz的(de)(de)(de)(de)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)信號,稱為(wei)(wei)(wei)超(chao)(chao)(chao)聲(sheng)(sheng)波(bo)(bo)(bo)(bo)。一(yi)個(ge)原因(yin)是(shi)液(ye)體中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)(de)局部拉應力形成負(fu)壓,壓力的(de)(de)(de)(de)減(jian)小使(shi)(shi)(shi)原溶(rong)解(jie)氣(qi)(qi)(qi)體飽(bao)和(he)(he)(he),但從液(ye)體中(zhong)(zhong)(zhong)(zhong)逃(tao)逸,成為(wei)(wei)(wei)一(yi)個(ge)小泡(pao)(pao);另一(yi)個(ge)原因(yin)是(shi)強拉應力將液(ye)體撕裂(lie)成一(yi)個(ge)孔,稱為(wei)(wei)(wei)空化(hua)(hua)(hua)。
