一(yi)(yi)、功(gong)率(lv)的(de)(de)選擇(ze) 超(chao)聲波清(qing)(qing)(qing)(qing)洗(xi)(xi)效(xiao)果(guo)(guo)不(bu)一(yi)(yi)定與(功(gong)率(lv)×清(qing)(qing)(qing)(qing)洗(xi)(xi)時(shi)(shi)間(jian)(jian))成正比,有(you)(you)時(shi)(shi)用(yong)(yong)(yong)小(xiao)功(gong)率(lv),花費很長時(shi)(shi)間(jian)(jian)也(ye)沒有(you)(you)清(qing)(qing)(qing)(qing)除(chu)污垢(gou)。而(er)如(ru)果(guo)(guo)功(gong)率(lv)達到一(yi)(yi)定數值,有(you)(you)時(shi)(shi)很快便將(jiang)污垢(gou)去除(chu)。若(ruo)(ruo)選擇(ze)功(gong)率(lv)太大,空(kong)化強度(du)將(jiang)大大增加,清(qing)(qing)(qing)(qing)洗(xi)(xi)效(xiao)果(guo)(guo)是提高了(le),但這時(shi)(shi)使(shi)較(jiao)精密的(de)(de)零(ling)(ling)(ling)件也(ye)產生(sheng)(sheng)蝕(shi)(shi)點(dian)(dian),得不(bu)償失(shi),而(er)且清(qing)(qing)(qing)(qing)洗(xi)(xi)缸(gang)底(di)(di)部(bu)振(zhen)動板處空(kong)化嚴重,水(shui)點(dian)(dian)腐(fu)蝕(shi)(shi)也(ye)增大,在(zai)(zai)(zai)采用(yong)(yong)(yong)三(san)氯乙烯等有(you)(you)機(ji)溶(rong)(rong)劑時(shi)(shi),基本上(shang)沒有(you)(you)問(wen)題,但采用(yong)(yong)(yong)水(shui)或水(shui)溶(rong)(rong)性清(qing)(qing)(qing)(qing)洗(xi)(xi)液(ye)時(shi)(shi),易于(yu)受(shou)到水(shui)點(dian)(dian)腐(fu)蝕(shi)(shi),如(ru)果(guo)(guo)振(zhen)動板表(biao)面已受(shou)到傷痕,強功(gong)率(lv)下水(shui)底(di)(di)產生(sheng)(sheng)空(kong)化腐(fu)蝕(shi)(shi)更嚴重,因此(ci)要(yao)按實際使(shi)用(yong)(yong)(yong)情況選擇(ze)超(chao)聲功(gong)率(lv)。 二、頻(pin)率(lv)的(de)(de)選擇(ze) 超(chao)聲清(qing)(qing)(qing)(qing)洗(xi)(xi)頻(pin)率(lv)從28kHz到120kHz之(zhi)間(jian)(jian),在(zai)(zai)(zai)使(shi)用(yong)(yong)(yong)水(shui)或水(shui)清(qing)(qing)(qing)(qing)洗(xi)(xi)劑時(shi)(shi)由空(kong)穴作(zuo)用(yong)(yong)(yong)引(yin)起(qi)的(de)(de)物理清(qing)(qing)(qing)(qing)洗(xi)(xi)力顯然對低頻(pin)有(you)(you)利,一(yi)(yi)般(ban)使(shi)用(yong)(yong)(yong)28-40kHz左右。對小(xiao)間(jian)(jian)隙(xi)、狹縫、深孔的(de)(de)零(ling)(ling)(ling)件清(qing)(qing)(qing)(qing)洗(xi)(xi),用(yong)(yong)(yong)高頻(pin)(一(yi)(yi)般(ban)40kHz以(yi)上(shang))較(jiao)好(hao)(hao),甚至幾(ji)百(bai)kHz。對鐘表(biao)零(ling)(ling)(ling)件清(qing)(qing)(qing)(qing)洗(xi)(xi)時(shi)(shi),用(yong)(yong)(yong)400kHz。若(ruo)(ruo)用(yong)(yong)(yong)寬(kuan)帶調頻(pin)清(qing)(qing)(qing)(qing)洗(xi)(xi),效(xiao)果(guo)(guo)更良好(hao)(hao)。 三(san)、清(qing)(qing)(qing)(qing)洗(xi)(xi)籃的(de)(de)使(shi)用(yong)(yong)(yong) 在(zai)(zai)(zai)清(qing)(qing)(qing)(qing)洗(xi)(xi)小(xiao)零(ling)(ling)(ling)件物品時(shi)(shi),常使(shi)用(yong)(yong)(yong)網籃,由于(yu)網眼要(yao)引(yin)起(qi)超(chao)聲衰(shuai)減,要(yao)特別引(yin)起(qi)注(zhu)意。當頻(pin)率(lv)為(wei)(wei)28khz時(shi)(shi)使(shi)用(yong)(yong)(yong)10mm以(yi)上(shang)的(de)(de)網眼為(wei)(wei)好(hao)(hao)。 四、清(qing)(qing)(qing)(qing)洗(xi)(xi)液(ye)溫(wen)度(du)的(de)(de)選擇(ze) 水(shui)清(qing)(qing)(qing)(qing)洗(xi)(xi)液(ye)最適宜的(de)(de)清(qing)(qing)(qing)(qing)洗(xi)(xi)溫(wen)度(du)為(wei)(wei)40-60℃,尤其在(zai)(zai)(zai)天(tian)冷時(shi)(shi)若(ruo)(ruo)清(qing)(qing)(qing)(qing)洗(xi)(xi)液(ye)溫(wen)度(du)低空(kong)化效(xiao)應差,清(qing)(qing)(qing)(qing)洗(xi)(xi)效(xiao)果(guo)(guo)也(ye)差。因此(ci)有(you)(you)部(bu)分清(qing)(qing)(qing)(qing)洗(xi)(xi)機(ji)在(zai)(zai)(zai)清(qing)(qing)(qing)(qing)洗(xi)(xi)缸(gang)外邊(bian)繞(rao)上(shang)加熱電(dian)熱絲(si)進行溫(wen)度(du)控制,當溫(wen)度(du)升(sheng)高后空(kong)化易發生(sheng)(sheng),所以(yi)清(qing)(qing)(qing)(qing)洗(xi)(xi)...
