超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)清(qing)洗(xi)(xi)(xi)(xi)原理(li)(li)就是(shi)在(zai)(zai)清(qing)洗(xi)(xi)(xi)(xi)液(ye)中(zhong)(zhong)(zhong)產(chan)(chan)(chan)生(sheng)“空(kong)化(hua)(hua)(hua)(hua)效(xiao)應(ying)”，即(ji)清(qing)洗(xi)(xi)(xi)(xi)液(ye)產(chan)(chan)(chan)生(sheng)拉伸和(he)壓(ya)(ya)縮現象，清(qing)洗(xi)(xi)(xi)(xi)液(ye)拉伸時會(hui)產(chan)(chan)(chan)生(sheng)大量微小氣泡(pao)(pao)，清(qing)洗(xi)(xi)(xi)(xi)液(ye)壓(ya)(ya)縮時氣泡(pao)(pao)會(hui)被壓(ya)(ya)碎破裂。這些氣泡(pao)(pao)產(chan)(chan)(chan)生(sheng)和(he)破裂的(de)(de)(de)(de)局部壓(ya)(ya)強(qiang)可(ke)達到上千個大氣壓(ya)(ya)的(de)(de)(de)(de)沖(chong)擊(ji)力(li)，這種(zhong)極強(qiang)大的(de)(de)(de)(de)壓(ya)(ya)力(li)足以使得物(wu)質分子發生(sheng)變化(hua)(hua)(hua)(hua)，引起各(ge)種(zhong)化(hua)(hua)(hua)(hua)學和(he)物(wu)理(li)(li)變化(hua)(hua)(hua)(hua)（分解、化(hua)(hua)(hua)(hua)合、乳化(hua)(hua)(hua)(hua)、分散(san)等(deng)），可(ke)以用(yong)于(yu)清(qing)除剝離(li)物(wu)件表(biao)面(mian)(mian)的(de)(de)(de)(de)灰(hui)塵、油污(wu)、銹跡等(deng)雜質。 空(kong)化(hua)(hua)(hua)(hua)效(xiao)應(ying)是(shi)決(jue)定清(qing)洗(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)的(de)(de)(de)(de)最主(zhu)要因素(su)，而(er)超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)頻(pin)(pin)(pin)率則(ze)直(zhi)接影(ying)響著空(kong)化(hua)(hua)(hua)(hua)效(xiao)果(guo)(guo)，一般產(chan)(chan)(chan)生(sheng)空(kong)化(hua)(hua)(hua)(hua)效(xiao)應(ying)的(de)(de)(de)(de)超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)頻(pin)(pin)(pin)率以20KHz-80KHz最為適(shi)合。 頻(pin)(pin)(pin)率與(yu)液(ye)體中(zhong)(zhong)(zhong)氣泡(pao)(pao)的(de)(de)(de)(de)直(zhi)徑(jing)成(cheng)(cheng)反(fan)比(bi)，與(yu)滲透(tou)性成(cheng)(cheng)正(zheng)比(bi)。頻(pin)(pin)(pin)率越(yue)(yue)高(gao)，波(bo)(bo)長(chang)較(jiao)(jiao)短(duan)(duan)，空(kong)泡(pao)(pao)直(zhi)徑(jing)小，爆炸壓(ya)(ya)力(li)低(di)，滲透(tou)性好(hao)，適(shi)合于(yu)表(biao)面(mian)(mian)光滑度(du)高(gao)、精(jing)細(xi)工(gong)件的(de)(de)(de)(de)清(qing)洗(xi)(xi)(xi)(xi)。另外(wai)，頻(pin)(pin)(pin)率也(ye)不能過高(gao)，否則(ze)波(bo)(bo)長(chang)減短(duan)(duan)，空(kong)化(hua)(hua)(hua)(hua)作(zuo)用(yong)反(fan)而(er)會(hui)減弱(ruo)，從而(er)降低(di)清(qing)洗(xi)(xi)(xi)(xi)效(xiao)率。 反(fan)之，超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)頻(pin)(pin)(pin)率越(yue)(yue)低(di)，在(zai)(zai)液(ye)體中(zhong)(zhong)(zhong)產(chan)(chan)(chan)生(sheng)空(kong)化(hua)(hua)(hua)(hua)越(yue)(yue)容易，產(chan)(chan)(chan)生(sheng)的(de)(de)(de)(de)力(li)度(du)大，作(zuo)用(yong)也(ye)越(yue)(yue)強(qiang)，適(shi)用(yong)于(yu)表(biao)面(mian)(mian)粗糙(cao)且較(jiao)(jiao)難(nan)清(qing)洗(xi)(xi)(xi)(xi)的(de)(de)(de)(de)污(wu)垢。超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)頻(pin)(pin)(pin)率還影(ying)響著工(gong)作(zuo)時所產(chan)(chan)(chan)生(sheng)的(de)(de)(de)(de)高(gao)頻(pin)(pin)(pin)噪(zao)聲(sheng)(sheng)(sheng)(sheng)，頻(pin)(pin)(pin)率越(yue)(yue)低(di)，噪(zao)聲(sheng)(sheng)(sheng)(sheng)越(yue)(yue)大，一般在(zai)(zai)滿足清(qing)洗(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)的(de)(de)(de)(de)前提下，盡量選(xuan)擇(ze)較(jiao)(jiao)高(gao)的(de)(de)(de)(de)頻(pin)(pin)(pin)率。基于(yu)以上原理(li)(li)：1、低(di)頻(pin)(pin)(pin)17K-23K：適(shi)用(yong)于(yu)清(qing)洗(xi)(xi)(xi)(xi)污(wu)垢較(jiao)(jiao)重或者比(bi)較(jiao)(jiao)難(nan)清(qing)洗(xi)(xi)(xi)(xi)的(de)(de)(de)(de)工(gong)件，且氣泡(pao)(pao)爆破沖(chong)擊(ji)力(li)對(dui)工(gong)件表(biao)面(mian)(mian)不會(hui)造(zao)成(cheng)(cheng)傷害(hai)時，應(ying)選(xuan)擇(ze)低(di)頻(pin)(pin)(pin)超(chao)(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)(bo)清(qing)洗(xi)(xi)(xi)(xi)，例如(ru)：汽配、紡織(zhi)等(deng)。2、中(zhong)(zhong)(zhong)頻(pin)(pin)(pin)25K-28K：適(shi)用(yong)于(yu)清(qing)洗(xi)(xi)(xi)(xi)污(wu)垢稍重或者清(qing)洗(xi)(xi)(xi)(xi)難(nan)易適(shi)中(zhong)(zhong)(zhong)，且氣泡(pao)(pao)爆破沖(chong)擊(ji)力(li)對(dui)工(gong)件表(biao)面(mian)(mian)不會(hui)造(zao)成(cheng)(cheng)傷害(hai)時，應(ying)選(xuan)擇(ze)中(zhong)(zhong)(zhong)...
