一(yi)(yi)、功(gong)(gong)率(lv)(lv)(lv)的(de)選(xuan)(xuan)擇(ze)(ze) 超(chao)聲波清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)不(bu)(bu)一(yi)(yi)定與(yu)(功(gong)(gong)率(lv)(lv)(lv)×清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi)間)成正比,有(you)時(shi)(shi)用(yong)(yong)(yong)(yong)小(xiao)功(gong)(gong)率(lv)(lv)(lv),花(hua)費很長時(shi)(shi)間也沒有(you)清(qing)(qing)(qing)除污垢。而如果(guo)(guo)功(gong)(gong)率(lv)(lv)(lv)達到(dao)一(yi)(yi)定數值,有(you)時(shi)(shi)很快便將污垢去除。若(ruo)選(xuan)(xuan)擇(ze)(ze)功(gong)(gong)率(lv)(lv)(lv)太大(da)(da),空(kong)(kong)化(hua)強(qiang)度(du)將大(da)(da)大(da)(da)增(zeng)加,清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)是提(ti)高了,但這時(shi)(shi)使(shi)(shi)較精密(mi)的(de)零件(jian)也產生蝕點,得不(bu)(bu)償(chang)失,而且清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)底部振動板處空(kong)(kong)化(hua)嚴(yan)(yan)重,水(shui)(shui)點腐(fu)(fu)蝕也增(zeng)大(da)(da),在采用(yong)(yong)(yong)(yong)三(san)氯乙烯等有(you)機(ji)溶劑(ji)時(shi)(shi),基本上(shang)沒有(you)問題,但采用(yong)(yong)(yong)(yong)水(shui)(shui)或水(shui)(shui)溶性清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)(ye)時(shi)(shi),易(yi)于受到(dao)水(shui)(shui)點腐(fu)(fu)蝕,如果(guo)(guo)振動板表面(mian)已受到(dao)傷痕,強(qiang)功(gong)(gong)率(lv)(lv)(lv)下水(shui)(shui)底產生空(kong)(kong)化(hua)腐(fu)(fu)蝕更嚴(yan)(yan)重,因(yin)(yin)此要按實際使(shi)(shi)用(yong)(yong)(yong)(yong)情況選(xuan)(xuan)擇(ze)(ze)超(chao)聲功(gong)(gong)率(lv)(lv)(lv)。 二、頻(pin)率(lv)(lv)(lv)的(de)選(xuan)(xuan)擇(ze)(ze) 超(chao)聲清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)頻(pin)率(lv)(lv)(lv)從(cong)28kHz到(dao)120kHz之(zhi)間,在使(shi)(shi)用(yong)(yong)(yong)(yong)水(shui)(shui)或水(shui)(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)劑(ji)時(shi)(shi)由空(kong)(kong)穴作(zuo)用(yong)(yong)(yong)(yong)引起(qi)的(de)物(wu)理清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)力顯然對(dui)低(di)頻(pin)有(you)利,一(yi)(yi)般使(shi)(shi)用(yong)(yong)(yong)(yong)28-40kHz左右。對(dui)小(xiao)間隙(xi)、狹縫、深孔(kong)的(de)零件(jian)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),用(yong)(yong)(yong)(yong)高頻(pin)(一(yi)(yi)般40kHz以上(shang))較好,甚至幾(ji)百kHz。對(dui)鐘表零件(jian)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)(yong)(yong)400kHz。若(ruo)用(yong)(yong)(yong)(yong)寬(kuan)帶調頻(pin)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi),效(xiao)果(guo)(guo)更良好。 三(san)、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)籃(lan)的(de)使(shi)(shi)用(yong)(yong)(yong)(yong) 在清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)小(xiao)零件(jian)物(wu)品時(shi)(shi),常使(shi)(shi)用(yong)(yong)(yong)(yong)網籃(lan),由于網眼要引起(qi)超(chao)聲衰減,要特(te)別引起(qi)注意。當(dang)頻(pin)率(lv)(lv)(lv)為(wei)28khz時(shi)(shi)使(shi)(shi)用(yong)(yong)(yong)(yong)10mm以上(shang)的(de)網眼為(wei)好。 四、清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)(ye)溫(wen)度(du)的(de)選(xuan)(xuan)擇(ze)(ze) 水(shui)(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)(ye)最適宜(yi)的(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)溫(wen)度(du)為(wei)40-60℃,尤其在天冷時(shi)(shi)若(ruo)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)液(ye)(ye)(ye)溫(wen)度(du)低(di)空(kong)(kong)化(hua)效(xiao)應(ying)差,清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)效(xiao)果(guo)(guo)也差。因(yin)(yin)此有(you)部分(fen)清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)機(ji)在清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)缸(gang)外邊繞上(shang)加熱(re)電熱(re)絲進行溫(wen)度(du)控(kong)制(zhi),當(dang)溫(wen)度(du)升(sheng)高后空(kong)(kong)化(hua)易(yi)發生,所以清(qing)(qing)(qing)洗(xi)(xi)(xi)(xi)(xi)...
