一、功(gong)(gong)率(lv)(lv)(lv)的(de)(de)選(xuan)擇 超聲波清(qing)(qing)洗(xi)(xi)(xi)(xi)效果(guo)(guo)(guo)不(bu)一定與(功(gong)(gong)率(lv)(lv)(lv)×清(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi)間(jian))成正(zheng)比,有時(shi)(shi)用(yong)(yong)(yong)小功(gong)(gong)率(lv)(lv)(lv),花費很長時(shi)(shi)間(jian)也(ye)沒有清(qing)(qing)除(chu)(chu)污(wu)垢(gou)。而如果(guo)(guo)(guo)功(gong)(gong)率(lv)(lv)(lv)達到(dao)一定數值,有時(shi)(shi)很快便將污(wu)垢(gou)去除(chu)(chu)。若(ruo)選(xuan)擇功(gong)(gong)率(lv)(lv)(lv)太大(da),空(kong)化(hua)強(qiang)度(du)將大(da)大(da)增加,清(qing)(qing)洗(xi)(xi)(xi)(xi)效果(guo)(guo)(guo)是提高(gao)了(le),但(dan)這(zhe)時(shi)(shi)使(shi)較(jiao)精密的(de)(de)零件也(ye)產生蝕點,得不(bu)償失,而且清(qing)(qing)洗(xi)(xi)(xi)(xi)缸底部振(zhen)動板處空(kong)化(hua)嚴(yan)重,水(shui)(shui)點腐(fu)蝕也(ye)增大(da),在(zai)采用(yong)(yong)(yong)三氯乙烯等(deng)有機(ji)(ji)溶劑(ji)(ji)時(shi)(shi),基本上沒有問題,但(dan)采用(yong)(yong)(yong)水(shui)(shui)或水(shui)(shui)溶性清(qing)(qing)洗(xi)(xi)(xi)(xi)液時(shi)(shi),易于(yu)受(shou)到(dao)水(shui)(shui)點腐(fu)蝕,如果(guo)(guo)(guo)振(zhen)動板表(biao)面已受(shou)到(dao)傷痕,強(qiang)功(gong)(gong)率(lv)(lv)(lv)下水(shui)(shui)底產生空(kong)化(hua)腐(fu)蝕更(geng)嚴(yan)重,因(yin)此要按實(shi)際使(shi)用(yong)(yong)(yong)情況選(xuan)擇超聲功(gong)(gong)率(lv)(lv)(lv)。 二、頻率(lv)(lv)(lv)的(de)(de)選(xuan)擇 超聲清(qing)(qing)洗(xi)(xi)(xi)(xi)頻率(lv)(lv)(lv)從28kHz到(dao)120kHz之間(jian),在(zai)使(shi)用(yong)(yong)(yong)水(shui)(shui)或水(shui)(shui)清(qing)(qing)洗(xi)(xi)(xi)(xi)劑(ji)(ji)時(shi)(shi)由空(kong)穴作(zuo)用(yong)(yong)(yong)引(yin)(yin)(yin)起的(de)(de)物理(li)清(qing)(qing)洗(xi)(xi)(xi)(xi)力顯然對低頻有利,一般(ban)使(shi)用(yong)(yong)(yong)28-40kHz左右。對小間(jian)隙、狹縫、深(shen)孔的(de)(de)零件清(qing)(qing)洗(xi)(xi)(xi)(xi),用(yong)(yong)(yong)高(gao)頻(一般(ban)40kHz以上)較(jiao)好(hao),甚至幾(ji)百kHz。對鐘表(biao)零件清(qing)(qing)洗(xi)(xi)(xi)(xi)時(shi)(shi),用(yong)(yong)(yong)400kHz。若(ruo)用(yong)(yong)(yong)寬(kuan)帶(dai)調頻清(qing)(qing)洗(xi)(xi)(xi)(xi),效果(guo)(guo)(guo)更(geng)良好(hao)。 三、清(qing)(qing)洗(xi)(xi)(xi)(xi)籃(lan)(lan)的(de)(de)使(shi)用(yong)(yong)(yong) 在(zai)清(qing)(qing)洗(xi)(xi)(xi)(xi)小零件物品時(shi)(shi),常使(shi)用(yong)(yong)(yong)網(wang)籃(lan)(lan),由于(yu)網(wang)眼(yan)要引(yin)(yin)(yin)起超聲衰減(jian),要特(te)別(bie)引(yin)(yin)(yin)起注意。當頻率(lv)(lv)(lv)為28khz時(shi)(shi)使(shi)用(yong)(yong)(yong)10mm以上的(de)(de)網(wang)眼(yan)為好(hao)。 四(si)、清(qing)(qing)洗(xi)(xi)(xi)(xi)液溫(wen)(wen)度(du)的(de)(de)選(xuan)擇 水(shui)(shui)清(qing)(qing)洗(xi)(xi)(xi)(xi)液最適宜的(de)(de)清(qing)(qing)洗(xi)(xi)(xi)(xi)溫(wen)(wen)度(du)為40-60℃,尤其在(zai)天冷時(shi)(shi)若(ruo)清(qing)(qing)洗(xi)(xi)(xi)(xi)液溫(wen)(wen)度(du)低空(kong)化(hua)效應差(cha),清(qing)(qing)洗(xi)(xi)(xi)(xi)效果(guo)(guo)(guo)也(ye)差(cha)。因(yin)此有部分清(qing)(qing)洗(xi)(xi)(xi)(xi)機(ji)(ji)在(zai)清(qing)(qing)洗(xi)(xi)(xi)(xi)缸外邊(bian)繞上加熱電熱絲(si)進行(xing)溫(wen)(wen)度(du)控(kong)制,當溫(wen)(wen)度(du)升(sheng)高(gao)后(hou)空(kong)化(hua)易發生,所以清(qing)(qing)洗(xi)(xi)(xi)(xi)...
