一、功率(lv)的(de)(de)選(xuan)擇(ze) 超聲波清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)不一定與(功率(lv)×清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi)間)成(cheng)正比,有(you)(you)時(shi)(shi)用(yong)(yong)(yong)(yong)(yong)小(xiao)功率(lv),花(hua)費(fei)很(hen)長時(shi)(shi)間也沒有(you)(you)清(qing)(qing)(qing)除污(wu)垢。而如果(guo)(guo)功率(lv)達到一定數值,有(you)(you)時(shi)(shi)很(hen)快便將污(wu)垢去(qu)除。若選(xuan)擇(ze)功率(lv)太大(da)(da),空(kong)(kong)化強(qiang)度(du)(du)(du)將大(da)(da)大(da)(da)增(zeng)加(jia),清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)是(shi)提高了,但這時(shi)(shi)使(shi)(shi)(shi)(shi)較(jiao)精密的(de)(de)零(ling)件也產(chan)生(sheng)蝕點(dian),得不償失,而且清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸底部振動(dong)板處空(kong)(kong)化嚴(yan)重(zhong),水(shui)點(dian)腐蝕也增(zeng)大(da)(da),在采用(yong)(yong)(yong)(yong)(yong)三氯乙烯(xi)等有(you)(you)機溶(rong)(rong)劑(ji)時(shi)(shi),基本上(shang)沒有(you)(you)問題,但采用(yong)(yong)(yong)(yong)(yong)水(shui)或(huo)水(shui)溶(rong)(rong)性清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液時(shi)(shi),易于受到水(shui)點(dian)腐蝕,如果(guo)(guo)振動(dong)板表面已受到傷痕,強(qiang)功率(lv)下水(shui)底產(chan)生(sheng)空(kong)(kong)化腐蝕更嚴(yan)重(zhong),因此要(yao)按實際(ji)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)情況選(xuan)擇(ze)超聲功率(lv)。 二、頻(pin)率(lv)的(de)(de)選(xuan)擇(ze) 超聲清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)頻(pin)率(lv)從28kHz到120kHz之間,在使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)水(shui)或(huo)水(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)劑(ji)時(shi)(shi)由空(kong)(kong)穴(xue)作用(yong)(yong)(yong)(yong)(yong)引起的(de)(de)物(wu)理(li)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)力顯(xian)然對(dui)低頻(pin)有(you)(you)利,一般使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)28-40kHz左右。對(dui)小(xiao)間隙(xi)、狹縫、深孔的(de)(de)零(ling)件清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),用(yong)(yong)(yong)(yong)(yong)高頻(pin)(一般40kHz以(yi)上(shang))較(jiao)好(hao)(hao),甚至幾百kHz。對(dui)鐘表零(ling)件清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)(yong)(yong)寬帶調頻(pin)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),效(xiao)果(guo)(guo)更良好(hao)(hao)。 三、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)籃(lan)的(de)(de)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong) 在清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)小(xiao)零(ling)件物(wu)品時(shi)(shi),常使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)網(wang)(wang)籃(lan),由于網(wang)(wang)眼(yan)要(yao)引起超聲衰(shuai)減(jian),要(yao)特別引起注(zhu)意。當頻(pin)率(lv)為28khz時(shi)(shi)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)(yong)10mm以(yi)上(shang)的(de)(de)網(wang)(wang)眼(yan)為好(hao)(hao)。 四、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液溫(wen)度(du)(du)(du)的(de)(de)選(xuan)擇(ze) 水(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液最適宜的(de)(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)溫(wen)度(du)(du)(du)為40-60℃,尤其在天冷時(shi)(shi)若清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液溫(wen)度(du)(du)(du)低空(kong)(kong)化效(xiao)應差,清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)也差。因此有(you)(you)部分清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機在清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸外(wai)邊繞上(shang)加(jia)熱(re)電熱(re)絲(si)進行溫(wen)度(du)(du)(du)控(kong)制(zhi),當溫(wen)度(du)(du)(du)升高后空(kong)(kong)化易發生(sheng),所(suo)以(yi)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)...
