一(yi)(yi)、功(gong)率(lv)(lv)的(de)(de)選(xuan)擇(ze)(ze) 超聲波清(qing)(qing)(qing)洗(xi)(xi)(xi)效果(guo)(guo)不一(yi)(yi)定(ding)與(功(gong)率(lv)(lv)×清(qing)(qing)(qing)洗(xi)(xi)(xi)時(shi)間)成正(zheng)比,有(you)(you)時(shi)用(yong)小(xiao)功(gong)率(lv)(lv),花費很(hen)長時(shi)間也(ye)沒有(you)(you)清(qing)(qing)(qing)除(chu)污垢。而如果(guo)(guo)功(gong)率(lv)(lv)達(da)到一(yi)(yi)定(ding)數值,有(you)(you)時(shi)很(hen)快(kuai)便將(jiang)污垢去除(chu)。若(ruo)選(xuan)擇(ze)(ze)功(gong)率(lv)(lv)太(tai)大,空(kong)(kong)化(hua)強度(du)將(jiang)大大增(zeng)(zeng)加,清(qing)(qing)(qing)洗(xi)(xi)(xi)效果(guo)(guo)是提高了,但這時(shi)使(shi)較(jiao)精密(mi)的(de)(de)零(ling)件(jian)(jian)也(ye)產生蝕(shi)點,得(de)不償失,而且清(qing)(qing)(qing)洗(xi)(xi)(xi)缸(gang)底部振(zhen)動板處空(kong)(kong)化(hua)嚴(yan)重,水(shui)(shui)點腐蝕(shi)也(ye)增(zeng)(zeng)大,在(zai)采(cai)用(yong)三(san)氯乙(yi)烯等有(you)(you)機(ji)溶劑(ji)時(shi),基(ji)本上沒有(you)(you)問題,但采(cai)用(yong)水(shui)(shui)或水(shui)(shui)溶性(xing)清(qing)(qing)(qing)洗(xi)(xi)(xi)液時(shi),易于受(shou)到水(shui)(shui)點腐蝕(shi),如果(guo)(guo)振(zhen)動板表面已受(shou)到傷痕,強功(gong)率(lv)(lv)下水(shui)(shui)底產生空(kong)(kong)化(hua)腐蝕(shi)更嚴(yan)重,因(yin)(yin)此(ci)要按實際(ji)使(shi)用(yong)情況(kuang)選(xuan)擇(ze)(ze)超聲功(gong)率(lv)(lv)。 二、頻(pin)(pin)率(lv)(lv)的(de)(de)選(xuan)擇(ze)(ze) 超聲清(qing)(qing)(qing)洗(xi)(xi)(xi)頻(pin)(pin)率(lv)(lv)從28kHz到120kHz之間,在(zai)使(shi)用(yong)水(shui)(shui)或水(shui)(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)劑(ji)時(shi)由空(kong)(kong)穴作(zuo)用(yong)引(yin)起的(de)(de)物理清(qing)(qing)(qing)洗(xi)(xi)(xi)力顯然(ran)對低(di)頻(pin)(pin)有(you)(you)利,一(yi)(yi)般(ban)使(shi)用(yong)28-40kHz左右。對小(xiao)間隙、狹縫、深孔(kong)的(de)(de)零(ling)件(jian)(jian)清(qing)(qing)(qing)洗(xi)(xi)(xi),用(yong)高頻(pin)(pin)(一(yi)(yi)般(ban)40kHz以(yi)上)較(jiao)好,甚(shen)至(zhi)幾百kHz。對鐘表零(ling)件(jian)(jian)清(qing)(qing)(qing)洗(xi)(xi)(xi)時(shi),用(yong)400kHz。若(ruo)用(yong)寬帶調(diao)頻(pin)(pin)清(qing)(qing)(qing)洗(xi)(xi)(xi),效果(guo)(guo)更良好。 三(san)、清(qing)(qing)(qing)洗(xi)(xi)(xi)籃(lan)的(de)(de)使(shi)用(yong) 在(zai)清(qing)(qing)(qing)洗(xi)(xi)(xi)小(xiao)零(ling)件(jian)(jian)物品時(shi),常(chang)使(shi)用(yong)網(wang)籃(lan),由于網(wang)眼要引(yin)起超聲衰減(jian),要特(te)別(bie)引(yin)起注意。當頻(pin)(pin)率(lv)(lv)為28khz時(shi)使(shi)用(yong)10mm以(yi)上的(de)(de)網(wang)眼為好。 四、清(qing)(qing)(qing)洗(xi)(xi)(xi)液溫度(du)的(de)(de)選(xuan)擇(ze)(ze) 水(shui)(shui)清(qing)(qing)(qing)洗(xi)(xi)(xi)液最適宜的(de)(de)清(qing)(qing)(qing)洗(xi)(xi)(xi)溫度(du)為40-60℃,尤其在(zai)天(tian)冷時(shi)若(ruo)清(qing)(qing)(qing)洗(xi)(xi)(xi)液溫度(du)低(di)空(kong)(kong)化(hua)效應差,清(qing)(qing)(qing)洗(xi)(xi)(xi)效果(guo)(guo)也(ye)差。因(yin)(yin)此(ci)有(you)(you)部分(fen)清(qing)(qing)(qing)洗(xi)(xi)(xi)機(ji)在(zai)清(qing)(qing)(qing)洗(xi)(xi)(xi)缸(gang)外邊繞上加熱電(dian)熱絲進行溫度(du)控制,當溫度(du)升高后空(kong)(kong)化(hua)易發生,所(suo)以(yi)清(qing)(qing)(qing)洗(xi)(xi)(xi)...
