全自(zi)動超(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)清(qing)(qing)(qing)洗(xi)(xi)機原理主要是(shi)將(jiang)(jiang)換(huan)能(neng)器，將(jiang)(jiang)功率(lv)超(chao)(chao)聲(sheng)(sheng)(sheng)頻(pin)源(yuan)的(de)(de)(de)聲(sheng)(sheng)(sheng)能(neng)，并且(qie)要轉換(huan)成(cheng)機械(xie)振(zhen)動，通(tong)過清(qing)(qing)(qing)洗(xi)(xi)槽壁使(shi)之將(jiang)(jiang)槽子(zi)(zi)中(zhong)(zhong)(zhong)的(de)(de)(de)清(qing)(qing)(qing)洗(xi)(xi)液(ye)輻(fu)射(she)(she)到(dao)(dao)超(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)。由于(yu)(yu)(yu)受(shou)到(dao)(dao)輻(fu)射(she)(she)的(de)(de)(de)超(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)，使(shi)之槽內液(ye)體(ti)(ti)(ti)(ti)(ti)中(zhong)(zhong)(zhong)的(de)(de)(de)微(wei)氣(qi)泡(pao)(pao)(pao)(pao)能(neng)夠在聲(sheng)(sheng)(sheng)波(bo)的(de)(de)(de)作(zuo)用(yong)(yong)下從(cong)而保(bao)持振(zhen)動。當聲(sheng)(sheng)(sheng)壓(ya)(ya)或者聲(sheng)(sheng)(sheng)強(qiang)受(shou)到(dao)(dao)壓(ya)(ya)力(li)到(dao)(dao)達一定程度(du)時(shi)(shi)候，氣(qi)泡(pao)(pao)(pao)(pao)就會迅速(su)膨(peng)脹，然后(hou)(hou)又突然閉合(he)。在這段過程中(zhong)(zhong)(zhong)，氣(qi)泡(pao)(pao)(pao)(pao)閉合(he)的(de)(de)(de)瞬間產(chan)(chan)生(sheng)(sheng)沖擊波(bo)，使(shi)氣(qi)泡(pao)(pao)(pao)(pao)周圍產(chan)(chan)生(sheng)(sheng)1012-1013pa的(de)(de)(de)壓(ya)(ya)力(li)及局調溫，這種超(chao)(chao)聲(sheng)(sheng)(sheng)波(bo)空化(hua)所產(chan)(chan)生(sheng)(sheng)的(de)(de)(de)巨大(da)壓(ya)(ya)力(li)能(neng)破(po)壞不(bu)溶(rong)(rong)性(xing)污(wu)(wu)(wu)(wu)物(wu)而使(shi)他們分化(hua)于(yu)(yu)(yu)溶(rong)(rong)液(ye)中(zhong)(zhong)(zhong)，蒸(zheng)汽型(xing)空化(hua)對污(wu)(wu)(wu)(wu)垢(gou)的(de)(de)(de)直接反復沖擊。一方面(mian)(mian)破(po)壞污(wu)(wu)(wu)(wu)物(wu)與清(qing)(qing)(qing)洗(xi)(xi)件(jian)表(biao)(biao)面(mian)(mian)的(de)(de)(de)吸(xi)附，另一方面(mian)(mian)能(neng)引起(qi)污(wu)(wu)(wu)(wu)物(wu)層的(de)(de)(de)疲勞破(po)壞而被(bei)駁(bo)離(li)，氣(qi)體(ti)(ti)(ti)(ti)(ti)型(xing)氣(qi)泡(pao)(pao)(pao)(pao)的(de)(de)(de)振(zhen)動對固體(ti)(ti)(ti)(ti)(ti)表(biao)(biao)面(mian)(mian)進行擦洗(xi)(xi)，污(wu)(wu)(wu)(wu)層一旦有縫可(ke)鉆(zhan)，氣(qi)泡(pao)(pao)(pao)(pao)立(li)即“鉆(zhan)入”振(zhen)動使(shi)污(wu)(wu)(wu)(wu)層脫(tuo)落(luo)，由于(yu)(yu)(yu)空化(hua)作(zuo)用(yong)(yong)，兩(liang)種液(ye)體(ti)(ti)(ti)(ti)(ti)在界面(mian)(mian)迅速(su)分散(san)而乳化(hua)，當固體(ti)(ti)(ti)(ti)(ti)粒子(zi)(zi)被(bei)油(you)污(wu)(wu)(wu)(wu)裹(guo)著而粘附在清(qing)(qing)(qing)洗(xi)(xi)件(jian)表(biao)(biao)面(mian)(mian)時(shi)(shi)，油(you)被(bei)乳化(hua)、固體(ti)(ti)(ti)(ti)(ti)粒子(zi)(zi)自(zi)行脫(tuo)落(luo)，超(chao)(chao)聲(sheng)(sheng)(sheng)在清(qing)(qing)(qing)洗(xi)(xi)液(ye)中(zhong)(zhong)(zhong)傳播時(shi)(shi)會產(chan)(chan)生(sheng)(sheng)正負交(jiao)變(bian)的(de)(de)(de)聲(sheng)(sheng)(sheng)壓(ya)(ya)，形(xing)成(cheng)射(she)(she)流，沖擊清(qing)(qing)(qing)洗(xi)(xi)件(jian)，同時(shi)(shi)由于(yu)(yu)(yu)非線性(xing)效應會產(chan)(chan)生(sheng)(sheng)聲(sheng)(sheng)(sheng)流和(he)微(wei)聲(sheng)(sheng)(sheng)流，而超(chao)(chao)聲(sheng)(sheng)(sheng)空化(hua)在固體(ti)(ti)(ti)(ti)(ti)和(he)液(ye)體(ti)(ti)(ti)(ti)(ti)界面(mian)(mian)會產(chan)(chan)生(sheng)(sheng)高速(su)的(de)(de)(de)微(wei)射(she)(she)流，所有這些(xie)作(zuo)用(yong)(yong)，能(neng)夠破(po)壞污(wu)(wu)(wu)(wu)物(wu)，除去或削弱邊界污(wu)(wu)(wu)(wu)層，增加攪拌、擴散(san)作(zuo)用(yong)(yong)，加速(su)可(ke)溶(rong)(rong)性(xing)污(wu)(wu)(wu)(wu)物(wu)的(de)(de)(de)溶(rong)(rong)解，強(qiang)化(hua)化(hua)學(xue)清(qing)(qing)(qing)洗(xi)(xi)劑的(de)(de)(de)清(qing)(qing)(qing)洗(xi)(xi)作(zuo)用(yong)(yong)。由此可(ke)見(jian)，凡是(shi)液(ye)體(ti)(ti)(ti)(ti)(ti)能(neng)浸到(dao)(dao)且(qie)聲(sheng)(sheng)(sheng)場存(cun)在的(de)(de)(de)地方都有清(qing)(qing)(qing)洗(xi)(xi)作(zuo)用(yong)(yong)，其(qi)特點適用(yong)(yong)于(yu)(yu)(yu)表(biao)(biao)面(mian)(mian)形(xing)狀非常復雜的(de)(de)(de)零件(jian)的(de)(de)(de)清(qing)(qing)(qing)洗(xi)(xi)。尤其(qi)是(shi)采用(yong)(yong)這一技術(shu)后(hou)(hou)，可(ke)減少化(hua)學(xue)溶(rong)(rong)劑的(de)(de)(de)用(yong)(yong)量(liang)，從(cong)而大(da)大(da)降低環境污(wu)(wu)(wu)(wu)染。
