超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)在(zai)液(ye)(ye)(ye)體(ti)(ti)中(zhong)(zhong)傳播，使液(ye)(ye)(ye)體(ti)(ti)和清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)槽在(zai)超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)頻(pin)(pin)(pin)率(lv)下振動(dong)(dong)，液(ye)(ye)(ye)體(ti)(ti)和清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)槽在(zai)自己的(de)(de)(de)(de)固(gu)有(you)頻(pin)(pin)(pin)率(lv)（即聲(sheng)(sheng)(sheng)(sheng)頻(pin)(pin)(pin)）下振動(dong)(dong)，人(ren)們聽到嗡(weng)嗡(weng)聲(sheng)(sheng)(sheng)(sheng)。沿著清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)行業(ye)的(de)(de)(de)(de)發展，越(yue)來(lai)越(yue)多的(de)(de)(de)(de)行業(ye)和企業(ye)使用超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機。依據超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)器的(de)(de)(de)(de)原理(li)，來(lai)源于超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)換能(neng)器的(de)(de)(de)(de)高(gao)頻(pin)(pin)(pin)率(lv)振動(dong)(dong)數(shu)據信號根據超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)換能(neng)器轉換為(wei)(wei)(wei)高(gao)頻(pin)(pin)(pin)率(lv)現代控制理(li)論，散播到做為(wei)(wei)(wei)物質的(de)(de)(de)(de)清(qing)(qing)(qing)(qing)理(li)有(you)機溶(rong)劑中(zhong)(zhong)，超(chao)(chao)(chao)(chao)音(yin)波(bo)(bo)在(zai)清(qing)(qing)(qing)(qing)潔液(ye)(ye)(ye)中(zhong)(zhong)粗密(mi)地前后左右放射性，使液(ye)(ye)(ye)體(ti)(ti)流動(dong)(dong)性而(er)(er)造成數(shu)十(shi)萬(wan)米的(de)(de)(de)(de)直徑(jing)50-500μm的(de)(de)(de)(de)細(xi)微汽泡(pao)，液(ye)(ye)(ye)體(ti)(ti)中(zhong)(zhong)存有(you)的(de)(de)(de)(de)細(xi)微汽泡(pao)在(zai)音(yin)場中(zhong)(zhong)振動(dong)(dong)。這些氣(qi)(qi)(qi)泡(pao)形成并(bing)生(sheng)(sheng)長在(zai)超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)縱向(xiang)傳輸負壓(ya)(ya)區,而(er)(er)在(zai)正(zheng)壓(ya)(ya)區,當聲(sheng)(sheng)(sheng)(sheng)壓(ya)(ya)達到一定值時,氣(qi)(qi)(qi)泡(pao)迅速(su)增加,然后突然關閉。并(bing)在(zai)氣(qi)(qi)(qi)泡(pao)閉合(he)時產生(sheng)(sheng)沖擊波(bo)(bo)，在(zai)其(qi)周(zhou)圍產生(sheng)(sheng)上千(qian)個(ge)(ge)大(da)氣(qi)(qi)(qi)壓(ya)(ya)，破(po)壞不(bu)溶(rong)性污(wu)物而(er)(er)使他(ta)們分(fen)散于清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)(ye)中(zhong)(zhong)，當團體(ti)(ti)粒(li)子(zi)(zi)被油(you)污(wu)裹著而(er)(er)黏附在(zai)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)件(jian)表(biao)面(mian)時，油(you)被乳化(hua)(hua)(hua)，固(gu)體(ti)(ti)粒(li)子(zi)(zi)及脫(tuo)離，從(cong)而(er)(er)達到清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)件(jian)凈(jing)化(hua)(hua)(hua)的(de)(de)(de)(de)目的(de)(de)(de)(de)。在(zai)這種被稱(cheng)之為(wei)(wei)(wei)“空(kong)化(hua)(hua)(hua)”效(xiao)(xiao)應的(de)(de)(de)(de)過程中(zhong)(zhong)，氣(qi)(qi)(qi)泡(pao)閉合(he)可形成幾百度的(de)(de)(de)(de)高(gao)溫和超(chao)(chao)(chao)(chao)過1000個(ge)(ge)氣(qi)(qi)(qi)壓(ya)(ya)的(de)(de)(de)(de)瞬間(jian)高(gao)壓(ya)(ya)。超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機的(de)(de)(de)(de)優點是(shi)：超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)清(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果好，操作簡單。人(ren)們聽到的(de)(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)音(yin)是(shi)20-20000Hz頻(pin)(pin)(pin)率(lv)高(gao)于20000Hz的(de)(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)信號,稱(cheng)為(wei)(wei)(wei)超(chao)(chao)(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)。一個(ge)(ge)原因是(shi)液(ye)(ye)(ye)體(ti)(ti)中(zhong)(zhong)的(de)(de)(de)(de)局部拉應力(li)(li)形成負壓(ya)(ya),壓(ya)(ya)力(li)(li)的(de)(de)(de)(de)減(jian)小使原溶(rong)解氣(qi)(qi)(qi)體(ti)(ti)飽和,但(dan)從(cong)液(ye)(ye)(ye)體(ti)(ti)中(zhong)(zhong)逃(tao)逸,成為(wei)(wei)(wei)一個(ge)(ge)小泡(pao);另(ling)一個(ge)(ge)原因是(shi)強拉應力(li)(li)將液(ye)(ye)(ye)體(ti)(ti)撕裂成一個(ge)(ge)孔(kong),稱(cheng)為(wei)(wei)(wei)空(kong)化(hua)(hua)(hua)。
