一(yi)(yi)、功(gong)(gong)(gong)率(lv)的(de)選擇 超聲波(bo)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果不一(yi)(yi)定與(功(gong)(gong)(gong)率(lv)×清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi)間)成正比,有(you)(you)時(shi)(shi)(shi)(shi)用(yong)(yong)(yong)(yong)小(xiao)功(gong)(gong)(gong)率(lv),花費很(hen)長時(shi)(shi)(shi)(shi)間也(ye)沒有(you)(you)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)除污垢。而(er)如果功(gong)(gong)(gong)率(lv)達到(dao)一(yi)(yi)定數值,有(you)(you)時(shi)(shi)(shi)(shi)很(hen)快(kuai)便將污垢去(qu)除。若選擇功(gong)(gong)(gong)率(lv)太大,空(kong)化強度(du)將大大增加,清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果是提高(gao)了,但這時(shi)(shi)(shi)(shi)使較精密的(de)零件也(ye)產生(sheng)蝕(shi)點,得(de)不償失,而(er)且清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)缸(gang)底部振動板處空(kong)化嚴重(zhong),水(shui)點腐(fu)蝕(shi)也(ye)增大,在采(cai)用(yong)(yong)(yong)(yong)三氯乙烯等有(you)(you)機溶劑(ji)時(shi)(shi)(shi)(shi),基本上沒有(you)(you)問題(ti),但采(cai)用(yong)(yong)(yong)(yong)水(shui)或(huo)水(shui)溶性(xing)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液(ye)時(shi)(shi)(shi)(shi),易于受到(dao)水(shui)點腐(fu)蝕(shi),如果振動板表面已受到(dao)傷痕,強功(gong)(gong)(gong)率(lv)下水(shui)底產生(sheng)空(kong)化腐(fu)蝕(shi)更嚴重(zhong),因此(ci)要(yao)按實際使用(yong)(yong)(yong)(yong)情(qing)況(kuang)選擇超聲功(gong)(gong)(gong)率(lv)。 二、頻(pin)率(lv)的(de)選擇 超聲清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)頻(pin)率(lv)從28kHz到(dao)120kHz之間,在使用(yong)(yong)(yong)(yong)水(shui)或(huo)水(shui)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)劑(ji)時(shi)(shi)(shi)(shi)由空(kong)穴作用(yong)(yong)(yong)(yong)引(yin)起的(de)物理(li)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)力(li)顯(xian)然對低頻(pin)有(you)(you)利,一(yi)(yi)般使用(yong)(yong)(yong)(yong)28-40kHz左右。對小(xiao)間隙(xi)、狹縫(feng)、深孔的(de)零件清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi),用(yong)(yong)(yong)(yong)高(gao)頻(pin)(一(yi)(yi)般40kHz以上)較好(hao),甚至幾百kHz。對鐘表零件清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)(shi),用(yong)(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)(yong)寬帶調(diao)頻(pin)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi),效(xiao)(xiao)果更良好(hao)。 三、清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)籃的(de)使用(yong)(yong)(yong)(yong) 在清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)小(xiao)零件物品時(shi)(shi)(shi)(shi),常使用(yong)(yong)(yong)(yong)網籃,由于網眼要(yao)引(yin)起超聲衰減,要(yao)特別引(yin)起注意(yi)。當(dang)頻(pin)率(lv)為(wei)28khz時(shi)(shi)(shi)(shi)使用(yong)(yong)(yong)(yong)10mm以上的(de)網眼為(wei)好(hao)。 四、清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)度(du)的(de)選擇 水(shui)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液(ye)最適宜的(de)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)溫(wen)度(du)為(wei)40-60℃,尤其在天冷時(shi)(shi)(shi)(shi)若清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)度(du)低空(kong)化效(xiao)(xiao)應差,清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)效(xiao)(xiao)果也(ye)差。因此(ci)有(you)(you)部分(fen)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)機在清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)缸(gang)外(wai)邊繞上加熱電熱絲(si)進行溫(wen)度(du)控制(zhi),當(dang)溫(wen)度(du)升(sheng)高(gao)后(hou)空(kong)化易發生(sheng),所以清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)(xi)...
