一(yi)、功(gong)(gong)(gong)率的(de)(de)(de)選擇(ze)(ze) 超(chao)聲(sheng)(sheng)波清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)不一(yi)定與(功(gong)(gong)(gong)率×清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi)間(jian))成正比,有(you)(you)(you)時(shi)(shi)(shi)用(yong)(yong)(yong)小(xiao)功(gong)(gong)(gong)率,花費(fei)很長時(shi)(shi)(shi)間(jian)也(ye)沒有(you)(you)(you)清(qing)(qing)(qing)(qing)(qing)除(chu)污垢。而如(ru)果(guo)(guo)功(gong)(gong)(gong)率達到一(yi)定數值,有(you)(you)(you)時(shi)(shi)(shi)很快(kuai)便將污垢去除(chu)。若選擇(ze)(ze)功(gong)(gong)(gong)率太大(da)(da),空(kong)(kong)化強(qiang)度(du)(du)(du)將大(da)(da)大(da)(da)增加,清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)是提高(gao)了(le),但這時(shi)(shi)(shi)使較精密的(de)(de)(de)零件(jian)也(ye)產生(sheng)蝕點(dian),得不償(chang)失,而且清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸底部(bu)振(zhen)動板處空(kong)(kong)化嚴(yan)重,水點(dian)腐蝕也(ye)增大(da)(da),在采(cai)(cai)用(yong)(yong)(yong)三氯乙烯等(deng)有(you)(you)(you)機溶劑時(shi)(shi)(shi),基本上沒有(you)(you)(you)問題,但采(cai)(cai)用(yong)(yong)(yong)水或水溶性清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)時(shi)(shi)(shi),易于受到水點(dian)腐蝕,如(ru)果(guo)(guo)振(zhen)動板表(biao)面已(yi)受到傷痕,強(qiang)功(gong)(gong)(gong)率下(xia)水底產生(sheng)空(kong)(kong)化腐蝕更嚴(yan)重,因此(ci)要按(an)實際使用(yong)(yong)(yong)情況(kuang)選擇(ze)(ze)超(chao)聲(sheng)(sheng)功(gong)(gong)(gong)率。 二、頻率的(de)(de)(de)選擇(ze)(ze) 超(chao)聲(sheng)(sheng)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)頻率從28kHz到120kHz之(zhi)間(jian),在使用(yong)(yong)(yong)水或水清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)劑時(shi)(shi)(shi)由空(kong)(kong)穴作用(yong)(yong)(yong)引(yin)起的(de)(de)(de)物理清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)力顯然對低(di)頻有(you)(you)(you)利(li),一(yi)般(ban)使用(yong)(yong)(yong)28-40kHz左(zuo)右。對小(xiao)間(jian)隙、狹縫、深孔的(de)(de)(de)零件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),用(yong)(yong)(yong)高(gao)頻(一(yi)般(ban)40kHz以(yi)(yi)上)較好(hao),甚至幾(ji)百kHz。對鐘(zhong)表(biao)零件(jian)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi)(shi),用(yong)(yong)(yong)400kHz。若用(yong)(yong)(yong)寬帶調(diao)頻清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),效果(guo)(guo)更良好(hao)。 三、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)籃(lan)的(de)(de)(de)使用(yong)(yong)(yong) 在清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)小(xiao)零件(jian)物品時(shi)(shi)(shi),常使用(yong)(yong)(yong)網(wang)籃(lan),由于網(wang)眼(yan)要引(yin)起超(chao)聲(sheng)(sheng)衰減,要特別(bie)引(yin)起注(zhu)意。當(dang)頻率為(wei)28khz時(shi)(shi)(shi)使用(yong)(yong)(yong)10mm以(yi)(yi)上的(de)(de)(de)網(wang)眼(yan)為(wei)好(hao)。 四、清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)度(du)(du)(du)的(de)(de)(de)選擇(ze)(ze) 水清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)最適宜的(de)(de)(de)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)溫(wen)度(du)(du)(du)為(wei)40-60℃,尤其在天冷時(shi)(shi)(shi)若清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)溫(wen)度(du)(du)(du)低(di)空(kong)(kong)化效應差(cha)(cha),清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效果(guo)(guo)也(ye)差(cha)(cha)。因此(ci)有(you)(you)(you)部(bu)分清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機在清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸外邊繞上加熱電熱絲進行溫(wen)度(du)(du)(du)控(kong)制,當(dang)溫(wen)度(du)(du)(du)升高(gao)后空(kong)(kong)化易發生(sheng),所以(yi)(yi)清(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)...
